초록
무치악 환자의 보철치료에서 총의치를 이용한 보철 치료 시 각화 점막을 통해 교합력을 분담하므로 저작력과 저작 능률이 떨어지고 특히 지지 점막 면적이 작은 하악의 경우 상악에 비해 통증 발생 등의 부작용이 더 많다. 치조골 흡수가 많은 환자일수록 이는 더 심화되나 하악 구치부 측의 하치조신경관의 존재 때문에 임플란트를 동반한 적극적 치료가 어려운 경우가 많다. 이에 본 증례에서는 상악에는 전통적인 총의치를 제작하고 하악은 치조골 높이가 충분한 전방부에만 임플란트를 식립하여 all-on-4 방법으로 치료한 환자에서 좋은 경과를 보여 보고하고자 한다.
Abstract
In the case of edentulous patients, the total amount of occlusal force is dispersed by the keratinized gingiva during mastication, in result, causing lower masticatory and chewing efficiency. In particular, the mandibular area has more side effects such as pain than the maxilla has. It gets worse when the patient has more absorption of alveolar bone, but the implant treatment is often interrupted due to the existence of the inferior alveolar nerve. In this case, a patient treated with the all-on-4 method by placing the implant in the anterior part of mandible and with the conventional complete denture for the maxilla has maintained without complications and was satisfied with the restoration both functionally and esthetically.
