초록

아름다운 미소는 좌우 대칭을 이루며 2 - 3 mm 치은을 보이는 상태를 일컫는다. 과다한 치은노출은 "거미 스마일"로 불리며 미적 장애로 인식되어 왔는데 원인으로는 지연맹출, 상악의 과도한 수직성장, 윗입술의 과도한 움직임 또는 짧은 윗입술로 등으로 보고되어왔다. 한편 클로스트리디움 보툴리눔 세균에서 생성된 외독소인 보툴리눔 독소는 투여된 부위의 신경말단에서 아세틸콜린의 유리를 막아서 근육 수축을 약화시켜 윗입술 과잉 운동으로 인한 치은과다노출증의 새로운 치료법으로 주목 받고있다. 현재까지 입술 주변 근육에 보툴리눔 독소를 주입하는 방법에 대한 많은 연구가 있었지만 아직 표준화 된 연구 방법과 치료 방법이 없어 치료 효과에 대한 논란이었다. 본 종설의 목적은 이러한 지난 과거의 연구들에서 적응증을 선택하기 위한 요소 및 보툴리눔 독소 치료의 효과를 분석하고자 한다. 특히 치은과다노출증에서 보툴리눔 독소 주사의 최적의 용량과 최적의 주사부위를 제시하고자 하였다.

A beautiful smile is made when it is symmetrical and gums are displayed less than 2 - 3 mm. Excessive gingival display also known as "gummy smile" is often recognized to be unaesthetic. Causes of gummy smile can be caused by delayed eruption, vertical maxillary excess, hypermobile upper lip, or a short upper lip. Meanwhile botulinum toxin which is an exotoxin produced from Clostridium botulinum, works by blocking the release of acetylcholine from the cholinergic nerve end plates leading to inactivity of the muscles. The application site and weakens the muscle tone is drawing attention as a gummy smile treatment caused by hypermobile upper lip. There have been many studies about the method of injecting botulinum toxin into muscles around the lips, but there is still no standardized research method and treatment method, so there is controversy over the therapeutic effect. The aim of this study is to review the previous studies about the predictors of indication and effects of gummy smile treatment using botulinum toxin injection. Especially we tried to propose a protocol for optimal dose and efficient injection point through the anatomical considerations for gummy smile treatment using botulinum toxin.
