RESUMO
Introduction: The crown lengthening surgery and the transurgical restoration are alternative procedures to enable the restoration of teeth inaccessible to the conventional techniques and restore the lost biological space. Objective: This study aimed to present clinically the reconstruction of a right maxillary second molar through crown lengthening surgery associated with transurgical restoration with composite resin in a patient treated in the Integrated Clinics of the University of Ribeirão Preto. Case report: Patient E.H.C.V., female, aged 51 years, attended the dental clinic of the University of Ribeirão Preto. The anamnesis showed a favorable health history and the clinical examination showed great tooth crown destruction of tooth #17. The treatment planning included the crown lengthening periodontal surgery with regularization of alveolar bone on the buccal surface of tooth #17, rubber dam isolation, the restauration of the compromised area with composite resin, and suture in the same session. After 7 days, the sutures were removed and the restoration polished. Conclusion: It can be concluded that the use of this technique is a viable, fast, and satisfactory solution, with good results, favoring the health and aesthetics, returning function and better social life to the patient.
RESUMO
Propósito: Describir una serie de casos en los que, por diferentes motivos, se debió realizarcirugía de alargamiento coronal, preparación dental y toma de impresión definitiva en unacita en dientes pilares de rehabilitación con prótesis fija. Métodos: Se reportan veinte casosde pacientes que requirieron tratamiento de rehabilitación definitiva en un número corto decitas por motivos de discapacidad, dificultad en la apertura bucal, poco tiempo en la ciudad,enfermedad sistémica o aprehensión. Dichos pacientes se sometieron a cirugía de alargamientocoronal, preparación dental y toma de impresión definitiva en zonas no estéticas enuna sola cita. Cuando fue requerido, hubo tratamiento previo de endodoncia y elaboraciónde postes. Resultados: No hubo complicaciones posquirúrgicas diferentes a las de todacirugía periodontal, como inflamación, dolor o sangrado, entre los veinte casos tratados.Conclusión: No se presentaron complicaciones en ninguno de los casos tratados. Se proponeesta conducta clínica en casos en los cuales esté indicada una cirugía de alargamientocoronal, preparación dental y toma de impresión definitiva en la misma cita...
Purpose: To describe a series of cases that, for different reasons, required crown lengthening surgery, dental preparation, and definitive dental impression performed in thesame appointment on pillar teeth for fixed dental prosthesis. Methods: This study reports a series of 20 patients who required definitive rehabilitation treatment in a small numberof appointments due to disability, mouth opening shortness, short stay in town, medicalcondition, or apprehensiveness. Patients underwent crown lengthening surgery, dental preparation,and definitive dental impression in non-aesthetic areas in the same appointment.When it was necessary, root canal and restoration with posts were carried out. Results:There were not postsurgical complications other than the usual localized periodontal inflammation,pain, and bleeding. Conclusion: There were no complications in the treatedcases. This clinical approach is recommended in cases where crown lengthening surgery,dental preparation and definite dental impressions in the same appointment are indicated...

O objetivo deste estudo clínico foi monitorar longitudinalmente a regeneração da papila interdentária (PI) após cirurgia de aumento de coroa. Foi selecionado, em 23 pacientes (idade média 32,5 anos) sem doença periodontal, um total de 30 dentes pré-molares com coroa clínica curta ou com invasão do espaço da distância biológica pela cárie, fratura dentária ou término cervical pré-existente. Os procedimentos cirúrgicos realizados foram: incisão, rebatimento de retalho total, ressecção óssea e sutura do retalho. Os parâmetros clínicos, como presença de placa e sangramento gengival nos sítios mesial e distal do pré-molar, e presença de cratera gengival, aspecto stippling e dobra nas PI, foram avaliados antes da cirurgia e nos períodos pós-operatórios de 1, 2, 3, 4, 5, 6 e 12 meses. Os resultados evidenciaram alterações morfológicas na PI durante todo período pós-operatório. A porcentagem média inicial de PI com aspecto stippling foi de 18,2%, reduzindo para 9,2% no primeiro mês pós-cirúrgico, e aumentando significantemente para 80,8%, aos 12 meses. A porcentagem média inicial de PI com cratera gengival e dobra de 49% e 63,9% aumentou significantemente para 76% e 100%, um mês após cirurgia, e reduziu significantemente para 11,4% e 32,9%, aos 12 meses, respectivamente. Os autores sugeriram a utilização da dobra como um parâmetro que permita ao profissional monitorar clinicamente a regeneração da PI.
The aim of this clinical study was to longitudinally observe the regeneration of the interdental papilla (IP) following surgical crown lengthening. A total of 30 premolars, which presented short clinical crown or loss of biological width due to caries, tooth fracture or preexisting cervical preparation, from 23 patients (mean age 32.5 years) without periodontal disease, was selected. The surgical procedures comprised incision, full-thickness flap, osseous resection and flap suture. The clinical parameters included presence of plaque and gingival bleeding at the mesial and distal aspects of the premolar and presence of gingival crater, stippling aspect and "folding" of the IP, before surgery and at postoperative periods of 1, 2, 3, 4, 5, 6 and 12 months. The results revealed morphological changes in the IP throughout the postoperative period. The initial mean percentage of IP with stippling aspect was 18,2%, then reduced to 9,2% at the first postoperative month and significantly increased to 80,8% at 12 months. The initial mean percentages of IP with gingival crater and "folding", 49% and 63,9%, were significantly increased to 76% and 100% at one month after surgery and significantly reduced to 11.4% and 32,9% after 12 months, respectively. The authors suggested utilization of "folding" as a parameter that allows the professionals to clinically observe the regeneration of the IP.
