Abstract

The canine tooth is important both functionally and aesthetically, being positioned between the anterior and posterior teeth. The upper canine has the longest eruption path, forming in the deepest part of the maxillary bone and often experiencing eruption disorders, leading to significant aesthetic and functional issues. Early detection and management of canine impaction are crucial in pediatric dentistry, which focuses on tooth growth and eruption. The prevalence of maxillary canine impaction ranges from 1.1% to 3.0%. In Western populations, palatal impaction is twice as common as labial impaction, while some Korean studies report more labial impaction. Maxillary canine impaction occurs more frequently in women and is associated with various factors such as structural obstacles, pathological conditions in surrounding tissues, developmental abnormalities, and genetic factors. Labial displaced canines are linked to narrow maxillary intercanine width, total dental crowding, and skeletal Class III malocclusion. Maxillary palatal displaced canine impaction is more prevalent in patients with familial agenesis of lateral incisors or conical supernumerary lateral incisors. Understanding these factors aids in early diagnosis and appropriate intervention for canine tooth impaction, ensuring optimal oral health and aesthetics.

상악 견치는 기능과 외모에 있어서 중요한 역할을 하지만, 맹출 장애로 인해 문제를 일으키는 경우가 많다. 상악 견치의 매복은 비교적 흔하며 구조적 장애, 발달 이상, 공간 부족, 유전과 같은 다양한 요인에 의해 발생할 수 있다. 상악 견치의 구개측 매복은 서양인에게서 흔한 것으로 보고되지만 한국인에게는 순측 매복이 더 흔한 것으로 관찰된다. 순측으로 변위된 상악 견치의 경우, 치아 총생 및 골격성 부정교합이 보일 수 있으며, 측절치의 선천적 상실이나 과잉 측절치는 상악 견치의 구개측 매복 가능성을 높일 수 있다. 상악 견치 매복의 조기 발견 및 적절한 처치는 조화로운 치열 발달과 정상적인 치아 기능을 위해 중요하다. 본 종설을 통해 매복 상악 견치의 다양한 처치법을 제안하고 그 원리를 설명하고자 한다.
