연구 목적: 양악 총의치를 사용 중인 환자를 대상으로 하악에 4개의 작은 직경의 임플란트를 식립하여 implant supported overdenture로 전환 시 환자의 만족도 (저작, 유지, 발음, 심미, 사회적 문제, 심리적 문제)를 평가하였다. 연구 재료 및 방법: 60세 이상의 완전 무치악 환자 중 상하악 총의치를 장착한 환자를 대상으로 하였다. 수술 전에 진단 스텐트를 이용한 방사선 사진 (CT, panorama) 촬영을 시행하고 현재 사용하고 있는 의치에 대한 만족도에 대해 조사하였다. 그 후 하악 이공 전방부에 4개의 mini dental implant 식립 및 immediate loading 후 방사선 사진 촬영을 하였다. 식립 1달후와 3달 후에 방사선 사진을 촬영하였으며 수술 전과 동일한 설문지를 통한 overdenture 사용 시 만족도 조사하였다. 결과: 현재 9명의 환자를 대상으로 시행하였다. 1. 총 36개의 임플란트를 식립하였으며 이중 1개의 임플란트가 실패하여 97.2%의 생존률을 보였다. 2. 임플란트 식립 전, 후만족도 비교는 oral health impact profile 49를 이용한 설문 조사를 통해 이루어 졌다. 저작 시 불편감, 유지, 발음, 심미, 사회적 활동시 불편감, 심리적 불편감 등으로 비교 분석하였으며 5점 기준으로 불편감이 심할수록 낮은 점수를 부여하였다. 그 결과 전반적으로 만족도가 상승하였다. 그 중 유지력 면에서 가장 크게 만족도가 상승하였으며 사회활동시 불편감, 심리적 불편감, 저작시 불편감, 심미, 발음 순으로 개선되었다. 결론:이번 연구를 통하여 mini dental implant를 이용한 의치를 사용시 환자의 만족도가 높아진 것을 볼 수 있었다. 추 후 좀 더 많은 환자를 통해 장기간 연구를 할 예정이며 추가적인 방사선 사진을 촬영하여 임플란트 주위 골 소실 여부를 관찰할 예정이다.
Abstract
PURPOSE: In cases when implant supported overdenture is made by using standard size implant, additional procedure such as bone surgery and bone grafting can be required. And it gives burden to doctor and patient in terms of cost. Therefore, it is necessary to find the implant therapy for the edentulous patients in making denture with accordable cost and simple procedure. MATERIALS AND METHODS: Edentulous patients with upper and lower dentures participated in this study. Before the operation, survey about patient’s satisfaction to the existing dentures was carried out. Surgical procedures included four small diameter implants installation anterior area and immediate loading. One and three month after the procedure, the same survey about patient’s satisfaction was carried out, and radiography was taken. RESULTS: We are doing research to the nine patients. Survival rate is 97.2 percent. The comparison of patient’s satisfaction before and after surgery is performed based on oral health impact profile 49. We analyze mainly with masticatory discomfort, retention, aesthetics, social problem, psychological discomfort problems. As a result, satisfaction level is increased at all factors. Retention is the most increased satisfactory factor followed by mastication difficulty, pronunciation, psychological discomfort, social discomfort, aesthetics in order. Marginal bone loss is 0.21 mm at 12 weeks after implant placement. CONCLUSION: This research reveals that the denture supported by mini dental implant increases patient’s satisfaction. This study will be continued with more patients for a long time and we are scheduled for taking additional radiography to check whether peri-implant bone resorption occurs or not.
