A systematic review and meta-analysis on the effects of crown lengthening on adjacent and non-adjacent sites

Abstract

Clinical and esthetic alterations on the adjacent/non-adjacent teeth can lead to clinical and esthetic alterations, which must be considered in surgical planning.

Multidisciplinary Management of Subgingivally Fractured Maxillary Incisor: A Clinical Case Report

“…By contrast, surgical crown lengthening is a faster procedure but involves removing the supporting alveolar bone, produces a high gingival contour, hampering soft tissue aesthetics and decreases the crown-root ratio [11,13]. The surgical procedure also compromises the periodontium of the adjacent non treated teeth [14]. This approach produces aesthetic problem in the anterior area, however, the palatal location of the subgingival fracture in our case permitted the exposure with a palatal flap elevation and osteotomy with minimal manipulation of the labial and interproximal tissues.…”

Retalho de reposição apical no tratamento de erupção passiva alterada – Caso Clínico

“…O alongamento coronário é indicado maioritariamente em casos onde se pretende melhorias estéticas, especialmente na presença de assimetrias gengivais, excesso gengival ou em situações clínicas de erupção passiva alterada. 10 O alongamento coronário contempla várias técnicas, incluindo a gengivectomia ou retalhos de reposicionamento apical, que poderão incluir ou não cirurgia óssea ressectiva. O retalho de reposicionamento apical deverá ser considerado sempre que uma excisão de tecidos por gengivectomia resulte numa largura gengival pós-operatória inferior a 3 mm.…”

“…Devido a este conceito, é imperativo que o alongamento coronário diste 3 mm entre a crista óssea e a JAC ou margem da restauração, garantindo a preservação deste espaço. 1,10,11 De modo a atingir um alongamento coronário proporcional e estético é vantajoso utilizarem-se medidores de proporção de Chu. Estas sondas de proporcionalidade adicionam uma abordagem biológica à técnica cirúrgica periodontal.…”

Does Surgical Crown Lengthening Procedure Produce Stable Clinical Outcomes for Restorative Treatment? A Meta‐Analysis

“…The indication for crown lengthening surgery suggests the need for proper access to sufficiently isolate the final prepared margins and to circumvent the consequences of improperly placed restorative margins that may lead to gingival inflammation and consequently periodontal deterioration . Crown lengthening is usually achieved by an apically positioned flap (APF) either with or without osseous resection or gingivectomy …”

“…4,5 The indication for crown lengthening surgery suggests the need for proper access to sufficiently isolate the final prepared margins and to circumvent the consequences of improperly placed restorative margins that may lead to gingival inflammation and consequently periodontal deterioration. 6,7 Crown lengthening is usually achieved by an apically positioned flap (APF) either with or without osseous resection or gingivectomy. [8][9][10] There are significant voids in the knowledge of several procedural aspects and clinical outcomes such as crown length (CL) increase, position of gingival margin (PGM), biological width (BW), bone level changes, probing depth (PD), and clinical attachment level (CAL) regarding esthetic surgical crown lengthening (SCL).…”
