Resumo(s)
A frenectomia é uma técnica cirúrgica que consiste na remoção de freios.
Existem vários tipos de frenectomias assim como vários tipos de freios (freio labial
superior, freio labial inferior, freios laterais e ainda freio lingual), que podem,
efetivamente, ser submetidos a esta intervenção. Relativamente às várias técnicas
cirúrgicas de frenectomia, esta tese aborda desde as mais convencionais, com
envolvimento de bisturi, como a plastia em V-Y, a plastia em Z, a frenectomia
romboidal e a técnica de Miller, às técnicas com recurso ao laser e ao eletrobisturi,
sendo todas estas intervenções direcionadas e relativas ao freio labial superior. Quando
os incisivos centrais superiores erupcionam separados, se o osso não se deposita na
porção inferior do freio, surge então a presença de um espaço interincisivo denominado
de diastema, podendo este interferir na harmonia e estética do sorriso, assim como na
função, havendo passagem de ar e de saliva através do mesmo. A frenectomia labial
superior é muitas vezes realizada concomitantemente ao tratamento ortodôntico.
Hoje em dia, ainda existe muita controvérsia relativamente à inserção anómala
do freio, pois ainda não se conseguiu concluir se esta é a causa ou uma consequência do aparecimento do diastema interincisivo maxilar. Existem diferentes abordagens
terapêuticas para o encerramento do diastema, no entanto há uma grande discussão
acerca de como e qual o melhor momento em que este deve ser realizado, de modo a
conseguir-se obter os melhores resultados possíveis e também com menor grau de
recidiva.
Esta tese visa uma revisão bibliográfica sobre a influência da frenectomia no diastema interincisivo maxilar e pretende descrever qual o estado da arte, atualmente, acerca deste tema.
Frenectomy is a surgical technique that consists of removing frenulum. There are several types of frenectomies as well as several types of frenulum (upper lip frenulum, lower lip frenulum, lateral frenulum and even lingual frenulum) that can, effectively, be submitted to this intervention. Regarding the various surgical techniques of frenectomy, this thesis addresses the most conventional ones, with scalpel involvement, such as V-Y plasty, Z plasty, rhomboid frenectomy and the Miller´s technique, as well as the techniques using laser and the electrocautery, with all these interventions directed and related to the upper lip frenulum. When the upper central incisors erupt separately, if the bone is not deposited in the lower portion of the frenulum, then there is the presence of an interincisive space called the diastema, which can interfere with the harmony and aesthetics of the smile, as well as interfering with the function, with passage of air and saliva through it. Upper lip frenectomy is often performed concurrently with orthodontic treatment. Nowadays, there is still much discussion regarding the anomalous insertion of the frenulum, as it has not yet been possible to conclude whether this is the cause or a consequence of the appearance of the maxillary interincisive diastema. There are different therapeutic approaches to the closure of the diastema. However, there is a great discussion about how and what is the best time to be performed, in order to achieve the best possible results and also with a lower degree of recurrence. This thesis aims at a literature review on the influence of frenectomy on the maxillary interincisive diastema and intends to describe the state of the art currently on this theme.
