상악동 거상술을 이용하여 구치부에 식립된 Branemark Ti-Unite와 ITI SLA 임플란트의 임상적 평가

Abstract

The predictable outcome of implant placement in the atrophic maxilla with sinus floor elevation procedure(osteotome sinus floor elevation technique and window opening technique) is well documented. Aim of this study was to evaluate the efficacy of Branemark Ti-Unite implant system and ITI SLA implant system placed in the atrophic posterior maxilla with sinus floor elevation procedure. Eighty patients received placement of Branemark Ti-Unite implants(195 implants) in their atrophic posterior Maxilla with sinus floor elevation procedure(153 osteotome sinus floor elevation technique and 42 window opening procedure). Fifty patients received placement of ITI SLA implants(83 implants) in their atrophic posterior Maxilla with sinus floor elevation procedure(77 osteotome sinus floor elevation technique and 6 window opening procedure). Chart review were taken from each patient. The total failed implants were seven and the total implant survival rate was 96.4% in Branemark Ti-Unite system. The total failed implants were one and the total implant survival rate was 98.8% in ITI SLA system. The implant survival rate with osteotome technique was 96% and 97.6% with window opening in Branemark Ti-Unite system. The implant survival rate with osteotome technique was 98.7% and 100% with window opening. The implant survival rate with osteotome technique was 96% and 97.6% with window opening in ITI SLA system. The results of this evaluation show that the placement of Branemark Ti-Unite system as well as ITI SLA system is a reasonable treatment option for patients with the atrophic posterior maxillary area.
