Aesthetic Crown Lengthening: Case Reports

The crown lengthening is indicated for aesthetic purposes, exposure of subgingival caries, crown fractures or a combination of these, which can be characterized as aesthetic or functional, related to restorative indications, and restoration of biological width. Several factors need to be evaluated in the aesthetic planning for optimizing the smile, with the inclusion of an increase in the clinical crown, emphasizing the quality of the thin or thick periodontal phenotype, an adequate band of keratinized tissue and the size of the biological width. A correct diagnosis of the gummy smile etiology, as well as an assessment of clinical characteristics and anatomical dimensions, is of fundamental importance prior to the patient's approach. It determines and guide decisions regarding the possibilities of treatment and prognosis of cases. The aim of this study was to report two cases of cosmetic periodontal surgery with techniques commonly used for this purpose: gingivectomy and flap surgery with osteotomy.

El alargamiento clínico de corona está indicado con fines estéticos, exposición de caries subgingivales, fracturas coronarias o alguna combinación de estas, y puede caracterizarse como estético o funcional, relacionado con indicaciones restaurativas y restauración del espacio biológico. Varios factores deben ser evaluados en la planificación estética para optimizar la sonrisa, con la inclusión del aumento clínico de coronas, destacando la calidad del fenotipo periodontal delgado o grueso, la gama adecuada de tejido queratinizado y la dimensión del espacio biológico. Un diagnóstico correcto de las causas asociadas a la sonrisa gingival, así como una valoración de las características clínicas y dimensiones anatómicas, son de fundamental importancia antes de abordar al paciente, para determinar y orientar decisiones respecto a las posibilidades de tratamiento y pronóstico de los casos. El objetivo de este estudio fue reportar dos casos de cirugía periodontal estética con técnicas comúnmente utilizadas para este fin: gingivectomía y cirugía de colgajo con osteotomía.

Therapy of gingival recessions using laterally positioned flap plus connective tissue graft: Case reports

ABSTRACT: Background: Gingival recession is an usual clinical condition with a multifactorial etiology, and its surgical treatment aims to improve aesthetics through root coverage, reducing dentin hypersensitivity, minimizing the risk of cervical caries, and increasing keratinized tissue. Objective: The aim of this study was to report the therapy used for two clinical cases of gingival recession in lower incisors. Methods: Miller class III and II gingival recessions were treated using the lateral flap associated with the connective tissue graft, with the maintenance of a keratinized tissue band in the tooth adjacent to the recession. Results: After 6 months a partial root coverage was obtained in the first case, above 70%, and complete root coverage at second case, with increase of keratinized tissue in both. Conclusion: The lateral flap associated with a connective tissue graft showed an effective technique, with good results in root coverage, gain of keratinized tissue, reduction of hypersensitivity and satisfactory esthetics in the treatment of Miller's class II and III gingival recession.
