RESUMEN

Introducción: el alargamiento de corona relacionado con la estética tiene como objetivo revelar una longitud adecuada de la corona y disminuir la exposición gingival. El procedimiento incluye gingivectomía y alveolectomía para restablecer el tejido gingival supracrestal requerido protésicamente según la dimensión fisiológica. Mediante un escaneo intraoral del maxilar, mandíbula y posición intercuspídea máxima y utilizando un software especializado, se diseña de manera digital la forma de los dientes y el contorno gingival. Este diseño genera una imagen de la restauración estética deseada para el prostodoncista y periodoncista. La fabricación física del diseño es asistida por computadora (CAD-CAM), creando una guía quirúrgica de resina acrílica moldeada al vacío para determinar la longitud de la corona clínica requerida en la cirugía. Objetivo: el caso interdisciplinario presentado describe una técnica innovadora empleando el flujo digital mediante un software que, a partir de un escaneo oral, diseña de manera digital un Mock-Up utilizado como guía para la cirugía periodontal. Presentación del caso: acude a clínica de la Maestría en Periodoncia de la Universidad Autónoma de Coahuila (UAdeC) paciente de 52 años, ASA I, para una cirugía periodontal con fines estéticos. Se procedió a la cirugía, colocando el Mock-Up en la región anterosuperior como guía para la gingivectomía. Luego, se realizó el levantamiento de colgajo antes de la alveolectomía, tomando en cuenta la longitud del tejido gingival supracrestal. Por último, se suturaron los tejidos blandos con técnica de colchonero horizontal. Resultados: siete días después, se retiran los puntos apreciando una cicatrización correcta y uniforme de los tejidos. Conclusiones: este abordaje digital ofrece una reducción significativa del tiempo quirúrgico, además de una estética satisfactoria y una precisa arquitectura gingival (AU)

Introduction: crown lengthening for aesthetic purposes aims to reveal an adequate crown length and reduce gingival exposure. The procedure includes gingivectomy and alveolectomy to restore the prosthetically required supracrestal gingival tissue according to physiological dimensions. Through an intraoral scan of the maxilla, mandible, and maximum intercuspidal position, and using specialized software, the shape of the teeth and the gingival contour are digitally designed. This design generates an image of the desired aesthetic restoration for the prosthodontist and periodontist. The physical fabrication of the design is computer-assisted (CAD-CAM), creating a vacuum-formed acrylic resin surgical guide to determine the clinical crown length required in surgery. Objective: the presented interdisciplinary case describes an innovative technique using digital workflow through software that, from an oral scan, digitally designs a Mock-Up used as a guide for periodontal surgery. Case presentation: a 52-year-old ASA I patient attended the Periodontics Master's clinic at Universidad Autónoma de Coahuila (UAdeC) for periodontal surgery with aesthetic purposes. The surgery was performed by placing the Mock-Up in the anterosuperior region as a guide for gingivectomy. Then, a flap was raised before the alveolectomy, considering the length of the supracrestal gingival tissue. Finally, the soft tissues were sutured with a horizontal mattress suture technique. Results: seven days later, the sutures were removed, showing correct and uniform tissue healing. Conclusions: this digital approach offers a significant reduction in surgical time, in addition to satisfactory esthetics and precise gingival architecture (AU)

RESUMEN

O sorriso gengival possui inúmeras causas, podendo acontecer por motivos esqueléticos, musculares ou por alteração no desenvolvimento dos tecidos de suporte. No entanto, na atualidade, a estética vermelha e a branca têm se apresentado completamente passíveis de transformações e com uma gama de procedimentos cirúrgicos ou não cirúrgicos para sanar as queixas dos pacientes. O objetivo geral deste trabalho é mostrar o poder que a odontologia tem frente às questões estéticas, como, por exemplo, a vergonha de sorrir por não se sentir confortável com os dentes curtos e com uma grande faixa de gengiva sendo exposta. O método utilizado foi um relato de caso. Que descreve todos os passos clínicos do tratamento de um paciente de 40 anos, que estava insatisfeita com o seu sorriso por apresentar erupção passiva alterada juntamente com hiperatividade do lábio superior. O plano de tratamento escolhido foi de realizar a cirurgia de aumento de coroa clínica estético, seguido de clareamento dentário e posteriormente um reposicionamento labial, com ajuda da toxina botulínica. Finalizando, para ajudar na cicatrização, o uso de laserterapia. O resultado de todo o processo cirúrgico envolvido neste trabalho, é satisfação do paciente, materializando o sonho deste, devolvendo segurança e espontaneidade ao sorrir. Pôde-se observar que através da combinação de técnicas cirúrgicas periodontais para tratar o sorriso gengival, obtém-se êxito tanto no sentido científico quanto no biológico, alcançando um sorriso esteticamente mais atrativo(AU)

Gummy smile has numerous causes, which can occur for skeletal or muscular reasons or due to changes in the development of supporting tissues. However, nowadays, the red and white aesthetics have been completely capable of transformation and with a range of surgical or non-surgical procedures to resolve patients' complaints. The general objective of this work is to show the power that dentistry has in the face of aesthetic issues, such as, for example, the shame of smiling due to not feeling comfortable with short teeth and a large strip of gum being exposed. The method used was a case report. Which describes all the clinical steps of the treatment of a 40-year-old patient, who was dissatisfied with her smile due to an altered passive eruption together with hyperactivity of the upper lip. The chosen treatment plan was to perform aesthetic clinical crown augmentation surgery, followed by tooth whitening and later lip repositioning, with the help of botulinum toxin. Finally, to help with healing, the use of laser therapy. The result of the entire surgical process involved in this work is patient satisfaction, materializing the patient's dream, restoring security and spontaneity when smiling. It was observed that through the combination of periodontal surgical techniques to treat gummy smile, success is achieved both in the scientific and biological sense, achieving a more aesthetically attractive smile(AU)

RESUMEN

OBJECTIVE: To compare the clinical periodontal parameters of teeth restored with a single ceramic crown, with and without crown lengthening procedure. METHODS: This prospective, longitudinal, controlled, and single-blinded clinical trial involved 22 patients with a total of forty-one teeth with ceramic crowns. The teeth were divided into two groups: test (n = 21), comprising teeth rehabilitated post crown-lengthening surgery, and control (n = 20), comprising teeth rehabilitated without crown-lengthening surgery. Plaque index (PI), gingival index (GI), probing depth (PD), bleeding on probing (BoP), and clinical attachment level (CAL) were compared between groups (surgically treated and non-surgically treated) and within each group for each type of site (treated -tt; adjacent - ad; and nonadjacent - nad). Additionally, gingival phenotype (GP), gingival recession (GR), and keratinized tissue width (KTW) were also assessed post- restoration. Statistical analyses used a significance level set at 5 %. RESULTS: PI, GI, and BoP were reduced, but no statistically significant differences were observed within each group or between groups for most follow-up periods. CAL of the TT sites was consistently higher in the test group, and PD was also higher in the test group (p < 0.05), except at T3. adPD, nadPD, adCAL, and nadCAL demonstrated no significant differences between groups and periods. A significant association was identified between GP and the occurrence of GR, with the thick-flat phenotype demonstrating less association with GR, regardless of whether crown lengthening was performed or not. CONCLUSION: Crown-lengthening surgery in rehabilitated teeth does not significantly affect PI and GI after 12 months. Although crown-lengthening surgery affected PD and CAL in TT sites, it did not affect adjacent and non-adjacent sites. CLINICAL RELEVANCE: These findings emphasize the importance of considering individual patient factors and the potential impact on periodontal tissues when planning crown-lengthening surgery. Clinicians must have a comprehensive understanding of the dynamics of the periodontal tissues involved in restorative treatments to optimize the procedure, increase success rates, and minimize potential complications.

RESUMEN

A busca por um sorriso considerado perfeito tem sido cada vez maior e isso tem se tornado um desafio para o Cirurgião-Dentista, visto que um sorriso harmônico não envolve somente dentes, mas também gengiva. A exposição excessiva da gengiva ao sorrir ou falar é considerada uma característica antiestética, pois gera uma desarmonia entre dentes, gengiva e lábios. Quando o paciente expõe 3 milímetros ou mais de gengiva ao sorrir, chamamos essa exposição de Sorriso Gengival. O presente trabalho tem como objetivo relatar o tratamento de um caso de sorriso gengival, onde foi realizada cirurgia periodontal ressectiva a fim de diminuir a exposição de tecido gengival ao sorrir. Descrição do caso: Paciente adulto 21 anos, sexo masculino, procurou atendimento no curso de graduação em Odontologia do Centro Universitário da Serra Gaúcha ­ FSG, com queixa de insatisfação estética devido ao tamanho de seus dentes e mostrar muito tecido Gengival ao sorrir. Após anamnese, exame clínico e radiográfico, o paciente foi diagnosticado com Sorriso gengival. O plano de tratamento proposto foi de cirurgia periodontal ressectiva. Conclusão: A partir do exposto, podemos concluir que o tratamento do sorriso gengival depende de sua etiologia. Um correto diagnóstico é de extrema importância, pois dependendo do fator etiológico do sorriso gengival, o plano de tratamento pode ser elaborado de acordo com a necessidade do paciente. No caso apresentado, o procedimento escolhido, cirurgia periodontal ressectiva, se mostrou efetivo no tratamento do sorriso gengival, devolvendo estética e satisfação ao paciente(AU)

The search for a smile that is considered perfect has been increasing and this has become a challenge for the Dental Surgeon, since a harmonious smile does not only involve teeth, but also gums. Excessive exposure of the gums when smiling or talking is considered an unsightly feature, as it creates disharmony between teeth, gums and lips. When the patient exposes 3 millimeters or more of gum when smiling, we call this exposure Gummy Smile. The present work aims to report the treatment of a case of gummy smile, where resective periodontal surgery was performed in order to reduce the exposure of gingival tissue when smiling. Case description: A 21-year-old adult patient, male, sought care at the undergraduate course in dentistry at the Centro Universitário da Serra Gaúcha ­ FSG, complaining of aesthetic dissatisfaction due to the size of his teeth and showing a lot of gingival tissue when smiling. After anamnesis, clinical and radiographic examination, the patient was diagnosed with gummy smile. The proposed treatment plan was resective periodontal surgery. Conclusion: From the above, we can conclude that the treatment of gummy smile depends on its etiology. A correct diagnosis is extremely important, because depending on the etiological factor of the gummy smile, the treatment plan can be elaborated according to the patient's needs. In the case presented, the chosen procedure, resective periodontal surgery, proved to be effective in the treatment of gummy smile, restoring aesthetics and patient satisfaction(AU)

RESUMEN

O anseio por um sorriso harmônico tem se tornado cada vez maior, uma vez que muitos pacientes relatam desconforto ao sorrir, pois correlacionam a estética do sorriso a problemas de baixa autoestima e em alguns casos suscetibilidade a alterações psicossociais decorrente aos padrões estéticos impostos pela sociedade. O sorriso gengival é uma das grandes queixas relatadas por pacientes. A exposição excessiva de gengiva maxilar pode ser decorrente a fatores gengivais, ósseos, dentários e musculares. Dentre os tratamentos disponíveis para diminuir essa exposição, contamos com cirurgias periodontais, aplicação de toxina botulínica, tratamentos ortodônticos, cirurgia ortognática e reposicionamento labial. O tratamento adequado será definido de acordo com o fator etiológico de cada caso. Diante disso o objetivo do trabalho é realizar um relato de caso sobre aumento de coroa clínica estética. A paciente estava descontente com a exibição de uma grande quantidade gengival ao sorrir. Após estudos clínicos e de imagem o diagnóstico foi de erupção passiva alterada, tipo IB. O tratamento de escolha foi a gengivoplastia associada a remodelação óssea osteotomia e osteoplastia. O tratamento estético vai além de uma boa aparência, através deste trabalho, foi possível evidenciar impactos benéficos que o sorriso harmônico pode acarretar na vida do indivíduo, atendendo suas expectativas e a do cirurgião-dentista(AU)

The desire for a harmonic smile has become increasing, since many patients report discomfort when smiling, as they correlate smile aesthetics to problems of low self-esteem and in some cases susceptibility to psychosocial changes due to aesthetic standards imposed by society. Gummy smile is one of the major complaints reported by patients. Excessive exposure of the maxillary gingiva may be due to gingival, bone, dental and muscular factors. Among the treatments available to reduce this exposure, we have periodontal surgeries, botulinum toxin application, orthodontic treatments, orthognathic surgery and lip repositioning. The appropriate treatment will be defined according to the etiological factor of each case. Therefore, the objective of this work is to carry out a case report on aesthetic clinical crown augmentation. Patient discount with the display of a large amount of gingival when smiling. After clinical and imaging studies, the diagnosis was an altered passive eruption, type IB. The treatment of choice was gingivoplasty associated with bone remodeling, osteotomy and osteoplasty. Final comments and conclusions: The aesthetic treatment goes beyond a good appearance, through this work, it was possible to evidence beneficial impacts that the harmonic smile can have on the individual's life, meeting their expectations and that of the dentist(AU)

RESUMEN

OBJECTIVES: To evaluate the stability of periodontal tissues 3 (T3), 6 (T6), and 12 (T12) months after esthetic crown lengthening (ACL) and the possible correlations between changes in those structures. MATERIALS AND METHODS: Twenty individuals were evaluated through clinical assessment, photography, and tomography. Measurements included gingival margin (GM), clinical crown length (CCL), interdental papilla height (PH) and width (PW), gingival thickness (GT), bone thickness (BT), probing depth (PD), distance between alveolar crest and GM, distance between alveolar crest and cementoenamel junction. Nonparametric and correlation statistics were performed (p < 0.05). RESULTS: CCL at T0 was 7.42 ± 0.70 mm and increased to 9.48 ± 0.49 mm immediately after ACL, but it decreased to 8.93 ± 0.65 mm at T12. PD decreased 0.60 mm from T0 to T6, and it increased 0.39 mm from T6 to T12. BT decreased 0.20 mm, while GT increased 0.29 mm from T0 to T12. Both PW and PH showed enlargement in T12. A positive moderate correlation was found between CCL/T0 and CCL/T12, GT/T0 and AC-GM/T12, BT/T0 and GT/T12. A few negative moderate correlations were PD/T0 and CCL/T12, PD/T0 and PH/T0, PD/T0 and BT/T12. CONCLUSIONS: ACL procedure was effective. Although some rebound occurred, that was not clinically important. PD tended to reestablish its original length, partially due to a migration of GM during the healing period. Besides, a thickening of supracrestal soft tissues was observed. CLINICAL RELEVANCE: The present study centers on the factors influencing the stability of periodontal tissues after esthetic crown lengthening, underscoring the procedure's influence on esthetics and biology and the need for careful treatment planning.

RESUMEN

OBJECTIVES: The aim of this case series is to present the potential applications of the GingivalStat approach, that is, the use of temporary gingival stabilizers, to favor early gingival margin remodeling and prevent the occurrence of gingival rebound following esthetic clinical crown lengthening. CLINICAL CONSIDERATIONS: Four patients requiring clinical crown lengthening were treated for esthetical and functional reasons. The surgical approach included: (a) gingival margin recontouring; (b) full-thickness flap elevation; (c) osteotomy (to achieve an adequate dimension between the alveolar bone crest and the CEJ) and osteoplasty (to reduce the bone thickness and improve the buccal bone anatomic profile, where indicated); (d) temporary gingival stabilizer placement using a block-out resin or a composite (the GingivalStat approach); and (e) flap repositioning, adaptation, and suture. One- to five-year follow-ups, reported in the different case scenarios, show evidence of clinically stable gingival margins around the treated teeth. CONCLUSIONS: Within the limits of this case series, it can be concluded that the GingivalStat approach appears as a further maneuver to cope with clinical crown lengthening procedures at esthetic sites. GingivalStat seems to favor gingival margin contour remodeling during the early phase of healing as well as prevent the occurrence of gingival rebound. CLINICAL SIGNIFICANCE: GingivalStat approach may guide gingival margin remodeling and prevent gingival rebound after wound healing of sites submitted to esthetic clinical crown lengthening.

RESUMEN

OBJECTIVE: To explore the feasibility of the usage of digital guides in combination with low- and high-power lasers for the treatment of excessive gingival display, also known as "gummy smile". CLINICAL CONSIDERATIONS: Excessive gingival display due to altered passive eruption can affect patient's perception of their own esthetics and consequently have an impact on self-confidence. Therefore, the management of this condition should offer a predictable and stable long-lasting solution. To attain these objectives, digital planning emerges as a tool in optimizing the outcomes of crown lengthening surgery for this condition by enhancing precision through the use of surgical guides. Additionally, the usage of high- and low-powered lasers can provide a safe approach because of their tissue selective removal properties. CONCLUSIONS: The technique described showed satisfactory clinical results in the short- and long-term follow-up, leading to an improvement in patients' self-esteem. This approach integrates digital and laser technologies to deliver a surgical treatment characterized by precision, efficiency, and safety. CLINICAL SIGNIFICANCE: Digital dentistry has contributed to innovative dental procedures, as personalizing surgical guides for patients, assisting and guiding incisions of the gingival margins, as well as the extension of the osteotomy, during the procedures for increasing the clinical crown. Furthermore, smile esthetics are directly related to an individual's improved emotional and social quality of life.

RESUMEN

A estética tem um papel importante na aceitação e autoestima das pessoas e, em virtude disso, os pacientes buscam cada dia mais ter um sorriso harmonioso. As reabilitações estéticas devem envolver um planejamento completo, atrelando função e estética, avaliando tamanho dos dentes, perfil e alturas gengivais, altura do sorriso e corredor bucal. Por conta disso, a odontologia nos permite uma série de abordagens terapêuticas diferentes que chegam a resultados satisfatórios para o paciente. Sendo assim, o presente trabalho tem como objetivo descrever um relato de caso de uma paciente com queixa estética do seu sorriso devido à diferentes tonalidades, formas e tamanhos dos dentes. Após anamnese, exame clínico e radiográfico, o plano de tratamento proposto foi de harmonizações periodontal com aumento de coroa e enxerto gengival, além de coroas em cerâmicas de dissilicato de lítio. Dentro desse contexto, mostra-se que uma abordagem multidisciplinar para reabilitação estética e funcional do sorriso é fundamental, a qual nos proporciona equilíbrio e naturalidade entre estética branca e vermelha no resultado do tratamento reabilitador(AU)

Aesthetics plays an important role in people's acceptance and self-esteem and, as a result, patients increasingly seek to have a harmonious smile. Aesthetic rehabilitations must involve a complete planning, linking function and aesthetics, evaluating tooth size, gingival profile and heights, smile height and buccal corridor. Because of this, dentistry allows us a series of different therapeutic approaches that reach satisfactory results for the patient. Therefore, the present work aims to describe a case report of a patient with an aesthetic complaint of her smile due to different shades, shapes and sizes of teeth. After anamnesis, clinical and radiographic examination, the proposed treatment plan was periodontal harmonization with crown augmentation and gingival graft, in addition to lithium disilicate ceramic crowns. Within this context, it is shown that a multidisciplinary approach to the aesthetic and functional rehabilitation of the smile is fundamental, which provides us with balance and naturalness between white and red aesthetics in the result of the rehabilitation treatment(AU)

RESUMEN

OBJECTIVES: The present study aimed to compare the guided dual technique with the conventional technique in esthetic crown lengthening (ECL). MATERIALS AND METHODS: The trial registration number is NCT04922086. Twenty-four participants diagnosed with altered passive eruption (APE) type I subcategory B were selected and allocated into two groups. In the control group (n = 12), the ECL procedure was planned by clinical examination and transgingival probing; in the test group (n = 12), the ECL procedure was carried out using digital planning and a double guide. Clinical parameters were assessed at baseline, immediately after the intervention (IAI), and at 4, 8, and 12 months of follow-up. RESULTS: The clinical crown length (CCL) mean at baseline was 8.09 mm (± 0.77) and increased significantly to 9.92 mm (± 0.62) IAI, with minimal significant reduction after 12 months (9.47 mm [± 0.60]) in the control group. Similarly, in the test group, the mean CCL at baseline was 8.04 mm (± 0.69) and increased significantly to 9.94 mm (± 0.57) IAI, with minimal reduction after 12 months (9.35 mm [± 0.80]). No differences were found between the mean CCL determined in the digital planning and after 12 months. No correlation was found between gingival thickness and gingival margin stability. High esthetic satisfaction was demonstrated by participants/specialists without differences between groups. CONCLUSIONS: In conclusion, the guided dual technique was as effective as the conventional technique for treatment of APE, with stable results after 12 months of follow-up. CLINICAL RELEVANCE: The guided dual technique aims to transfer both the gingival and bone resection planned position to facilitate the ECL surgical procedure and increase treatment predictability.

RESUMEN

AIM: To assess the effect of aesthetic crown lengthening (ACL) and lip repositioning surgery (LRS) on perception of smile attractiveness. MATERIALS AND METHODS: Preoperative and 6-month postoperative smile photographs of ACL- or LRS-treated patients were evaluated by 100 raters (five gender-balanced groups of ten per procedure) of diverse background (dental students, general dentists, periodontists and laypersons with and without any aesthetic concerns about their own smile). Smile attractiveness was rated by visual analogue scale (VAS). Multivariate mixed-effect models were applied to determine the effect of procedure, rater (age, gender and group) and case (gingival display and GD) on smile attractiveness rating. RESULTS: Average preoperative and postoperative VAS scores for ACL patients were 3.8 ± 2.0 and 6.2 ± 1.9, respectively. Corresponding LRS patient values were 4.8 ± 2.0 and 6.4 ± 1.9. Treatment, baseline GD and rater age were significant determinants (p < .001) of smile attractiveness for both procedures. Rater gender was not significant. Rater group was significant (p < .032) only for ACL. Procedure (p < .001), baseline VAS (p < .001), change in GD (p ≤ .002) and rater age (p ≤ .017) were significant determinants of smile attractiveness change from preoperative to postoperative. CONCLUSIONS: ACL and LRS are two periodontal plastic surgery procedures that deliver significant smile attractiveness improvements, in the eyes of both laypersons and dental professionals.

RESUMEN

Una de las causas de la evolución de la periodontitis es la formación de defectos óseos y pérdida de inserción clínica. Una manera de eliminar el defecto intraóseo y su bolsa periodontal es eliminar las paredes de hueso que componen el defecto para colocar el complejo dentogingival en una posición más apical. La cirugía ósea es un procedimiento periodontal resectivo que involucra la modificación del tejido óseo del soporte dental, la cual es una modalidad del tratamiento periodontal quirúrgico que puede utilizarse para eliminar eficazmente los defectos óseos periodontales para estabilizar la inserción periodontal. El objetivo del presente estudio es realizar una revisión de la literatura sobre las consideraciones actuales, técnicas y principios de la cirugía ósea resectiva en el paciente periodontalmente comprometido (AU)

One of the causes of the evolution of periodontitis is the formation of bone defects and loss of clinical attachment, where one way to eliminate the intraosseous defect and its periodontal pocket is to eliminate the bone walls that make up the defect to place the dentogingival complex in a more apical position. Bone surgery is periodontal surgery that involves the modification of the supporting bone tissue of the teeth, which is a modality of surgical treatment that can be used to effectively eliminate periodontal defects and stabilize the periodontal insertion. The aim of the present study is to conduct a literature review about the considerations, techniques and principles of resective bone surgery in the periodontally compromised patient (AU)

RESUMEN

A proposta desta revisão da literatura foi avaliar as técnicas empregadas no afastamento gengival para prótese dental incluindo métodos mecânicos, químicos-mecânicos e cirúrgicos. A técnica de afastamento gengival deve ser previamente avaliada pelo profissional e a sua indicação, dependerá de cada situação clínica. Nesta revisão foram apresentadas as vantagens e desvantagens das técnicas de afastamento gengival incluindo fio afastador embebido ou não em soluções químicas, técnicas cirúrgicas, procedimentos a base de laser, curetagem gengival e eletro cirurgia. Após a realização desta revisão verificamos que o método químico-mecânico é o mais utilizado pelos profissionais. Atualmente podemos considerar que mesmo com a utilização de tecnologias mais elaboradas, como por exemplo scanners intraorais, quando o término do preparo dental estiver ao nível gengival ou subgengival se faz necessário o afastamento gengival. Para atingir o sucesso de uma prótese dental e importante coexistir uma harmonia entre a prótese e os tecidos periodontais circunvizinhos. (AU)

The aim of this review was to assess the use of gingival retraction methods in the fixed tooth supported prosthesis including mechanical, chemicals-mechanical and surgical methods. The choice of the best gingival retraction technique should be considered previously by the professional and it depends of each individual clinical conditions. In this review were discussed the advantages and the disadvantages of each gingival retraction technique including mechanical, chemical and surgical methods. In this review, we could understand that chemicals-mechanical technical is the most indicate by dentists. Nowadays, we can consider that even with the hightech use in dental area, such as intraoral scanners, when the margin of the restoration is placed sub-gingivally the gingival retraction should be considered. For the successful in dental prosthesis, a healthy coexistence between the restoration and their surrounding periodontal structure should be the goal of a prosthodontist. (AU)
