平台转换种植体在上颌前牙区的临床应用
Clinical application of platform switching implants in maxillary anterior region
摘要
Abstract
Objective To evaluate the application effect of the platform switching implants in maxillary anterior region, to explore the effect of platform switching technology on the surrounding tissues. Methods 55 patients with 60 single maxillary anterior implants were divided into two groups:platform-switching implants group (Ankylos), 25 patients with 28 implants;butt-joint implants group (Nobel Replace), 30 patients with 32 implants. The patients received follow-up care more than 1 and 2 year after the final setting of the prosthesis, at which time periapical radiographs were taken. The marginal bone level around the implant and Pink Esthetic Score (PES) were measured for comparison. Results The average marginal bone changes of platform-switching implants after 1 year and 2 year were (-0.41 ± 0.36) mm and (-0.55 ± 0.33) mm respectively;and the ones of butt-joint implants were (-1.77 ± 0.54) mm and (-1.82 ± 0.61) mm. The average PES of platform-switched implants after 1 year and 2 year were 10.43 ± 1.37 and 10.32 ± 1.21 respectively;the ones of butt-joint implants were 9.21 ± 0.97 and 9.16 ± 0.95. There were significantly differences of marginal bone changes and PES between both groups (P<0.05). Conclusion Platform switching implant in the maxillary aesthetics area is more effective in preserving the surrounding bone tissue and aesthetic effect.关键词
