RESUMEN
OBJECTIVES: The present study aimed to explore the impact of different periodontal surgical treatments on the quality of life and postoperative morbidity. MATERIALS AND METHODS: The present study is a single-center, prospective, observational cohort trial. One hundred fifty-five patients, referred to the Periodontal Department of Bologna University who needed periodontal surgical treatment, were recruited. The self-reported perception of the postoperative course was assessed using the following anonymous questionnaires: Italian oral health impact profile (I-OHIP-14), visual analog scale (VAS) to evaluate the intensity of the pain, and 5-point Likert scale. RESULTS: Patients reported a mean OHIP-14 total score of 9.87±8.5 (range 0-42), significantly influenced by the female sex, flap extension, and periodontal dressing. A mean VAS score of 2.96±2.39 (range 0-9) was calculated, and was found to be influenced by the presence of vertical releasing incisions and palatal flap extension. Of the 155 subjects, 40 (25.8%) patients reported bleeding as a post-surgical complication, 96 (61.9%) swelling, 105 (67.7%) eating discomfort, and 44 (28.4%) reported speech discomfort. CONCLUSIONS: Within the limitations of the nature of the present study, periodontal surgical procedures have a low impact on patients' quality of life evaluated through the OHIP-14 and VAS pain questionnaires. CLINICAL RELEVANCE: Periodontal surgical procedures are safe procedures, with a limited duration of postoperative discomfort as well as the incidence of complications.

Root coverage procedures have become very common in clinical dental practice. Even though these techniques are considered safe, the clinician may face several issues during the therapy due to their surgical nature. Some of these issues can be defined strictly as complications inherent to the procedure, whereas others are medical errors or treatment errors. This review will focus on describing treatment errors and complications that may arise during different phases of the root coverage therapeutic process and on how to prevent and manage them.

OBJECTIVES: The treatment of gingival recessions (GRs) is operator-sensitive and dependent upon several local anatomical factors. The aim of this study was to introduce a difficulty score for the treatment of localized GRs with the coronally advanced flap (CAF) and to test its consistency among different operators. MATERIALS AND METHODS: A rubric (difficulty score) consisting of the assessment and grading of 8 anatomical parameters (anatomical papilla, apical and lateral keratinized tissue width, apical and lateral frenum, vestibulum depth, scar tissue, and mucosal invagination) is described based on the available evidence and the authors' experience. Inter-examiner agreement, with the score, was tested on 32 localized GRs among four different experienced practitioners. RESULTS: Minor discrepancies were observed in the total scores between the reviewers (intraclass correlation coefficient [ICC] 0.95). A good reproducibility, with ICCs ranging from 0.56 to 0.98, was found for the individual parameters. All models showed high absolute variance contribution conveying true differences among the cases, and small examiner variance, demonstrating minor systematic variability among the four reviewers and reproducible evaluations. CONCLUSIONS: The proposed difficulty score for the treatment of GRs with CAF was reproducible among different operators. Clinical interventional studies are the next step to validate the clinical magnitude of the present score. CLINICAL RELEVANCE: A novel tool for evaluating the difficulty of the treatment of isolated gingival recession using CAF was described. Clinicians can benefit from this score when assessing the expected level of complexity of the surgical case.

Treatment of gingival recessions affecting mandibular incisors is scarcely documented. Despite a shallow vestibule depth being considered a poor anatomical condition, it has never been measured nor deemed a clinical parameter affecting the outcome of root coverage procedures. This study describes a vertically and coronally advanced flap (V-CAF) + connective tissue graft (CTG) technique to obtain root coverage and increased vestibule depth in the treatment of gingival recessions affecting mandibular incisors. Twenty patients with single gingival recessions were treated. The results showed that V-CAF+CTG is effective in increasing residual vestibule depth and in reducing recession depth. Immediately after surgery, a vestibule-depth increase of 5.9 ± 1.2 mm was reported, which was statistically significant compared to baseline, and it remained stable after 12 months (4.8 ± 1.1 mm). The mean percentage of root coverage was 98.3% ± 5.2% for all treated recessions, and complete root coverage (CRC) was achieved in 90% of cases (18 of 20). V-CAF+CTG could be considered a successful technique in terms of vestibule depth increase and CRC for the treatment of single gingival recessions in the mandibular incisors.

BACKGROUND: The incidence of a peri-implant soft tissue dehiscence/deficiency (PSTD) is not a rare finding. Despite multiple previous attempts aimed at correcting the PSTDs, a classification of these conditions has not yet been proposed. This lack in the literature may also lead to discrepancies in the reported treatment outcomes and thus misinform the clinician or the readers. The aim of the present article was therefore to present a classification of peri-implant PSTD at a single implant site. METHODS: Four classes of PSTDs were discussed based on the position of the gingival margin of the implant-supported crown in relation to the homologous natural tooth. In addition, the bucco-lingual position of the implant head was also taken into consideration. Each class was further subdivided based on the height of the anatomical papillae. RESULTS: Subsequently, for each respective category a surgical approach (including bilaminar techniques, the combined prosthetic-surgical approach or soft tissue augmentation with a submerged healing) was also suggested. CONCLUSION: This paper provides a new classification system for describing PSTDs at single implant sites, with the appropriate recommended treatment protocol.

PURPOSE: To report the 5-year clinical and aesthetic outcomes of a novel surgical-prosthetic approach for the treatment of buccal soft tissue dehiscence around single dental implants. MATERIALS AND METHODS: Twenty patients with buccal soft tissues dehiscence around single implants in the aesthetic area were treated by removing the implant-supported crown, reducing the implant abutment, coronally advanced flap in combination with connective tissue graft and final restoration. After the first year, patients were recalled three times a year until the final clinical re-evaluation performed 5 years after the final prosthetic crown. Complications, bleeding on probing (BoP), peri-implant probing depth (PPD), clinical attachment level (CAL), keratinized tissue height (KTH), soft tissue coverage and thickness (STT), patient satisfaction (VAS) and aesthetic assessment (PES/WES) were evaluated 5 years after the final restoration. RESULTS: Of the 20 patients enrolled in the study, 19 completed the study at 5 years. A total of 99.2% mean soft tissue dehiscence coverage, with 79% of complete dehiscence coverage, was achieved at 5 years. A statistically significant increase in buccal soft tissue thickness (0.3 mm 0.1-0.4 P < 0.001) and keratinized tissue height (0.5 mm 0.0-1.0; P < 0.001) at 5 years with respect to 1 year was demonstrated. The patient aesthetic evaluation showed high VAS scores with no statistical difference between 1 year and 5 years (8.75 ± 1.02 and 8.95 ± 0.91 respectively). A statistical significant PES/WES score improvement was observed between baseline and 5 years (9.48 ± 2.68; P < 0.001), but not between 1 and 5 years. CONCLUSIONS: Successful aesthetic and soft tissue dehiscence coverage outcomes were well maintained at 5 years. The strict regimen of post-surgical control visits and the emphasis placed on the control of the toothbrushing technique could be critical for the successful long-term maintenance of soft tissue dehiscence coverage results.

Criteria for successful implants, in the rehabilitation of a single missing tooth in the esthetic area, should be determined by composite outcomes, including functional and esthetic aspects of soft tissues and the reconstruction, as well as patient-reported outcomes. This paper focuses on current methods in esthetic assessment and patient-centered/reported outcomes in single-tooth implant rehabilitation in the esthetic area. The relationship between subjective, patient-based esthetic evaluations and objective, professional-based esthetic evaluations is reviewed. In spite of increasing interest in the assessment of 'success' in implant dentistry, it is not yet possible to provide evidence-based conclusions because of the lack of consensus on a universal implant-supported crown esthetic index. There is also a need to standardize reporting of patient-centered outcomes in partially edentulous patients treated with implants.

Loss of dentition leads to functional and esthetic challenges that are determined by the anatomic features of the edentulous area. These features can complicate the prosthetic rehabilitation of such patients, especially in situations where optimal esthetic outcomes are desired. For these reasons, reconstructive plastic surgery procedures, aimed at restoring the alveolar ridge to its former dimensions, have become of great clinical interest. These reconstructive plastic surgery procedures frequently involve soft-tissue augmentation, performed to improve the quality and quantity of mucogingival tissue with the aim to achieve an ideal esthetic result. This review will focus on the description and expected outcomes of different surgical techniques for soft-tissue augmentation in edentulous areas, as described in the literature. Although more information from a larger number of studies and randomized controlled clinical trials is needed, it is possible to draw some conclusions, namely: pouch procedures are the first choice for soft-tissue augmentation, especially in high-demand esthetic areas; roll techniques are possible in shallow buccolingual soft-tissue augmentations; and onlay, inlay and combination grafts are less suitable for soft-tissue augmentation because of their poor esthetic results.

Altered passive eruption is described as a condition in which the relationship between teeth, alveolar bone and soft tissues creates an excessive display of gingiva, commonly known as a 'gummy smile'. While there are authors who consider altered passive eruption to be a risk to periodontal health, its impact is greatest in terms of oral esthetics. The aim of periodontal management in such cases is not only to improve patient esthetics but also to restore periodontal health by re-establishing the normal relationship between the gingival margin, alveolar bone crest and cemento-enamel junction. The aim of this article is to present a narrative review of the etiology, classification and management of altered passive eruption.

Treatment of buccal gingival recession is performed for esthetic concerns, root sensitivity, root caries and cervical abrasion resulting from incorrect toothbrushing. Over the years, clinicians and researchers have improved surgical techniques to achieve surrogate end points, such as complete root coverage, gingival recession reduction or keratinized tissue increase, ignoring the input from the patient regarding the true indications for treatment. In the past few years there has been an emphasis to include patient-centered outcomes in the evaluation of root-coverage procedures. The aim of this narrative review is to describe the professional objective assessment of the esthetic results after root-coverage procedures and the patient perception of outcome in terms of esthetics, postoperative morbidity and dentinal hypersensitivity resolution after the treatment of gingival recessions. The need to align professional (surrogate) end points with patient-centered outcomes (true end points) in the future is emphasized.

Soft-tissue dehiscence at the facial aspect of an osteointegrated implant is a common complication which impacts on the final esthetic result. The etiology and ways of diagnosing this condition are still controversial. Many factors seem to influence the position of the peri-implant soft-tissue margin, and some of these have been studied more carefully than others. Various surgical and combination surgical-prosthetic approaches have been described to treat soft-tissue dehiscence, with the latter appearing to be more predictable. This paper focuses on the factors affecting peri-implant soft-tissue margins and describes the different treatment approaches, reported in the literature, to treat buccal soft-tissue dehiscence, with more focus on the prosthetic-surgical-prosthetic approach.

The present case report describes a modification of the connective tissue graft wall technique with enamel matrix derivative applied to treat deep vertical bony defects. The technique presented uses a palatal incision to gain access to the bony defect. Deep infrabony defects affecting two maxillary central incisors associated with interdental and buccal gingival recession were treated. At 1 year after surgery, 9 and 6 mm of interdental clinical attachment level gain were seen in cases 1 and 2, respectively. The position of the interdental papilla was improved, and complete root coverage was achieved. Radiographs demonstrated bone fill of the infrabony components of the defects. This report encourages the possibility to improve, in one surgical session, regenerative and esthetic parameters in the treatment of deep infrabony defects.

The present case report describes the application of the connective tissue graft wall (CTGW) technique for the treatment of deep lingual gingival recessions associated with probing pockets and bone loss. Two deep lingual gingival recessions affecting the mandibular central incisors associated with severe lingual attachment and bone loss were treated. The surgical technique comprised a connective tissue graft (CTG) placed below a trapezoidal-type coronally advanced flap (CAF) acting as a lingual soft tissue wall of the infrabony defect. One year after the surgery, clinically significant root coverage, an increase in lingual keratinized tissue (KT) height and thickness, and clinical attachment level gain were achieved in both treated teeth. This case report encourages the application of the CTGW technique to improve both root coverage and regenerative parameters in lingual gingival recessions associated with severe attachment and bone loss.

The aim of the present case series study was to evaluate the short- and long-term (3 years) soft tissue stability of a surgical technique combining transmucosal implant placement with submarginal connective tissue graft (CTG) in an area of shallow buccal bone dehiscence. A sample of 20 patients were treated by positioning a transmucosal implant in an intercalated edentulous area. A CTG sutured to the inner aspect of the buccal flap was used to cover the shallow buccal bone dehiscence. Clinical evaluations were made at 6 months (T1) and 1 (T2) and 3 (T3) years after the surgery. Statistically significant increases in buccal soft tissue thickness and improvement of vertical soft tissue level were achieved at the T1, T2, and T3 follow-ups. A significant increase in keratinized tissue height was also found at T3. No significant marginal bone loss was recorded. The submarginal CTG technique was able to provide simultaneous vertical and horizontal soft tissue increases around single implants with shallow buccal bone dehiscence and no buccal mucosal recession or clinical signs of mucositis or peri-implantitis at 1 and 3 years.

The aim of this parallel double-blind randomized controlled clinical trial was to describe a modified approach using the coronally advanced flap (CAF) with triangular design and to compare its efficacy, in terms of root coverage and esthetics, with a trapezoidal type of CAF. A sample of 50 isolated Miller Class I and II gingival recessions with at least 1 mm of keratinized tissue apical to the defects were treated with CAF. Of these recessions, 25 were randomly treated with trapezoidal CAF (control group) while the other 25 (test group) were treated with a modified triangular CAF. The clinical and esthetic evaluations, made by the patient and an independent periodontist, were performed 3 months, 6 months, and 1 year after the surgery. No statistically significant difference was demonstrated between the two CAF groups in terms of recession reduction, complete root coverage, or 6-month and 1-year patient esthetic scores. Better 3-month patient esthetic evaluations and better periodontist root coverage, color match, and contiguity assessments were reported after triangular CAF. Trapezoidal CAF was associated with greater incidence of keloid formation. Single-type gingival recessions can be successfully covered with both types of CAF. The triangular CAF should be preferred for esthetically demanding patients.

The aim of the present case series article was to provide a standardized approach for the early restorative phase after a crown-lengthening surgical procedure. Different advantages can be ascribed to this approach: the clinician can prepare a definitive prosthetic finishing line in the supragingival location; the early postsurgical temporization allows the conditioning of soft tissues, especially the interdental papillae, during their maximum growing phase; and the clinician can choose the time for the definitive prosthetic rehabilitation in a patient-specific manner according to the individual potential and duration of the soft tissue rebound. In this study, this standardized approach was applied to the treatment of two esthetic cases requiring crown-lengthening procedures.

This paper presents a novel electromyography (EMG)-driven hand exoskeleton for bilateral rehabilitation of grasping in stroke. The developed hand exoskeleton was designed with two distinctive features: (a) kinematics with intrinsic adaptability to patient's hand size, and (b) free-palm and free-fingertip design, preserving the residual sensory perceptual capability of touch during assistance in grasping of real objects. In the envisaged bilateral training strategy, the patient's non paretic hand acted as guidance for the paretic hand in grasping tasks. Grasping force exerted by the non paretic hand was estimated in real-time from EMG signals, and then replicated as robotic assistance for the paretic hand by means of the hand-exoskeleton. Estimation of the grasping force through EMG allowed to perform rehabilitation exercises with any, non sensorized, graspable objects. This paper presents the system design, development, and experimental evaluation. Experiments were performed within a group of six healthy subjects and two chronic stroke patients, executing robotic-assisted grasping tasks. Results related to performance in estimation and modulation of the robotic assistance, and to the outcomes of the pilot rehabilitation sessions with stroke patients, positively support validity of the proposed approach for application in stroke rehabilitation.

The case reports in this article describe a surgical approach for improving root coverage and clinical attachment levels in Miller Class IV gingival recessions. Two gingival recessions affecting maxillary and mandibular lateral incisors associated with severe interdental hard and soft tissue loss were treated. The surgical technique consisted of a connective tissue graft (CTG) that was placed below a coronally advanced envelope flap and acted as a buccal soft tissue wall of the bony defect treated with enamel matrix derivative (EMD). No palatal/lingual flap was elevated. In the first clinical case, 6 months after surgery a ceramic veneer was placed to correct tooth extrusion and improve the overall esthetic appearance. One year after the surgery in both cases, clinically significant root coverage, increase in buccal keratinized tissue height and thickness, improvement in the position of the interdental papilla, and clinical attachment level gain were achieved. The radiographs demonstrate bone fill of the intrabony components of the defects. This report encourages a novel application of CTG plus EMD to improve both root coverage and regenerative parameters in Miller Class IV gingival recessions.

AIM: The aim of this study was to compare the clinical and aesthetic outcomes of two different surgical approaches for the treatment of deep gingival recession affecting the mandibular incisors. METHODS: Fifty patients with Miller class I and II gingival recessions (≥ 3 mm) in the lower incisors were enrolled. Twenty-five patients were randomly assigned to the control group and the other 25 patients to the test group. All defects were treated with the coronally advanced flap + connective tissue graft (CAF + CTG) and in the test group the labial submucosal tissue (LST) was removed. Post-operative morbidity was evaluated at 1 week. Clinical and aesthetic evaluations were made at 1 year. RESULTS: Statistically greater recession reduction, probability of CRC (adjusted OR 7.94 95% CI = 1.88-33.50, p = 0.0024) and greater increase in GT were observed in the test group. Greater graft exposure and increase in KTH were demonstrated in the control group. Better aesthetics outcomes were observed in the test group. No statistically significant between groups differences were demonstrated in patient analgesic assumption and post-operative discomfort and bleeding. CONCLUSIONS: LST removal during CAF + CTG surgery is indicated to provide better root coverage and aesthetic outcomes in the treatment of gingival recessions affecting the lower incisors.

AIM: Primary aim of this study was to evaluate if patient morbidity was improved by diminishing graft thickness and height; secondary objective was to evaluate if such graft modifications influence root coverage and aesthetic outcomes. METHODS: 60 Miller class I and II gingival recessions (GR) (≥ 3 mm in depth) were treated with the coronally advanced flap plus extraoral de-epithelialized free gingival graft (FGG). In 30 randomly selected control GRs ("big graft group"), the FGG thickness was ≥ 2 mm and the height was equal to bone dehiscence (BD); in the other 30 test defects ("small graft group"), the thickness of the FGG was <2 mm and the height was 4 mm. The post-operative patient morbidity was assessed 1 week after the surgery. The clinical and aesthetic evaluations were performed 1 year after the surgery. RESULTS: Lower analgesic assumption, better post-operative course evaluations, better patient colour match scores and better periodontist aesthetic assessments were reported in the "small graft" group. No statistically significant differences were demonstrated between the two groups in terms of recession reduction, CRC and increase in KTH. Greater GT increase was obtained in the control-treated sites. CONCLUSIONS: Coronally advanced flap plus CTG of reduced thickness and height was associated with less patient morbidity, better aesthetic evaluations with no difference in RC outcomes.
