Abstract(s)
O alongamento coronário é um dos procedimentos mais realizados em
Periodontologia. Engloba uma grande variedade de técnicas cirúrgicas e não cirúrgicas,
com o objetivo de aumentar a exposição da coroa dentária, em doentes com excesso de
tecido gengival, ou como técnica adjuvante a procedimentos restauradores.
Esta revisão bibliográfica tem como objetivo estudar as várias técnicas de alongamento coronário, suas indicações e contraindicações, bem como rever a importância da avaliação do fenótipo gengival no planeamento terapêutico.
Adicionalmente, serão revistos os fatores que influenciam a maturação dos tecidos moles periodontais e a posição final da margem gengival pós-cirúrgica.
Foi realizada uma pesquisa bibliográfica utilizando os termos “crown lengthening
surgery AND gingival biotype”, “crown lengthening surgery AND surgical techniques”,
“crown lengthening surgery AND gingival margin position” e “crown lengthening
surgery AND surgical complications”, nas bases de dados Pub-Med, Medline, Cochrane
e SciELO. Foi dada preferência a meta-análises, revisões sistemáticas e a estudos
randomizados controlados.
O alongamento coronário cirúrgico está indicado na abordagem de cáries ou fraturas subgengivais, em situações de invasão dos tecidos aderidos supracrestais e ainda
em casos com discrepância das margens gengivais. A gengivectomia e a realização de
cirurgia de retalho, com ou sem osteotomia, representam as técnicas cirúrgicas mais
aplicadas.
A extrusão ortodôntica é uma técnica não cirúrgica, normalmente utilizada como alternativa às técnicas cirúrgicas de alongamento coronário.
Apesar de serem conhecidos alguns dos fatores implicados na posição final da margem gengival, estão descritas situações de migração apical ou coronal da mesma, com o passar do tempo.
O alongamento coronário é uma técnica periodontal valiosa no sentido de recriar um sorriso harmonioso. Com este objetivo, a associação de procedimentos periodontais
e protéticos é muitas vezes necessária e benéfica.
Crown lengthening surgery is a commonly performed technique in Periodontology. It involves several surgical and non-surgical techniques, aiming to enhance the exposition of the crown, in patients with redundant gingival tissue or as an adjuvant technique to restorative procedures. This literature review aims to study the various crown lengthening techniques, their indications and contraindications, and review the importance of the gingival phenotype evaluation in the therapeutic plan. A literature review in Pub-Med, Medline, Cochrane e SciELO databases was performed using the terms “crown lengthening surgery AND gingival biotype”, “crown lengthening surgery AND surgical techniques”, “crown lengthening surgery AND gingival margin position” e “crown lengthening surgery AND surgical complications”. There was a preference for meta-analysis, systematic reviews and randomized controlled trials. Surgical crown lengthening is indicated while treating caries or subgingival fractures, in cases of invasion of the supracrestal gingival tissues or in situations where there are discrepancies in the gingival margin. Gingivectomy and flap surgery with or without osteotomy represent the most used crown lengthening surgical techniques. The orthodontic extrusion is the most used crown lengthening non-surgical technique, normally applied as an alternative to surgical procedures. Although several factors involved in the final position of the gingival margin are already known, there are still described situations of apical or coronal gingival migration over time. Crown lengthening is a valuable periodontal technique which can help recreate a harmonious smile. Also, the association between periodontal and prosthetic procedures is many times necessary and beneficial.
