초록
상악 전치부에서 임플란트의 순구개측 식립 위치는 보철물의 심미성을 결정하는 중요한 요소이다. 그러나 상악 전치부의 얇은 순측골은 발치 후에 상당한 양이 흡수되어, 임플란트가 이상적 식립 위치보다 구개측에 식립될 수 있다. 본 상악 중절치 상실 증례들에서 다소 구개측에 식립된 임플란트의 보철 수복을 위하여 UCLA 지대주를 이용하였다. 또한 타과와 협진으로 발치 후 흡수된 치조골 외형과 치은의 형태 회복을 위하여 골유도재생술을 시행하였고, 인접전치를 재배열 하였다. 충분한 임시 보철물 수복 기간으로 치은 형태의 심미적 회복을 확인한 뒤에 최종 보철 시행하였으며, 임플란트 보철을 통한 치아 상실 부위의 기능, 심미 회복이 만족할 만한 결과를 보였다.
Abstract
The labio-palatal location of the implant in the maxillary anterior region is one of the important factors affecting the aesthetics of the implant prosthesis. However, the thin labial bone of maxilla could be absorbed in significant amounts after extraction of the teeth, which makes the implant be placed on the palatal side rather than the ideal location. In fact, in the cases of maxillary central incisor loss, UCLA was used for prosthetic restoration of palatally placed implant. In addition, with multidisciplinary treatment, GBR (Guided Bone Regeneration) was performed for compensating the absorbed alveolar bone and adjacent anterior tooth were aligned. Definitive restoration was performed after confirming aesthetic recovery of the gingiva with sufficient provisional restoration period. There were satisfactory results of functional and esthetic recovery of tooth loss through implant prosthesis.
