영문 초록

Purpose: Simultaneous implantation has been traditionally limited to patients with at least 5 mm of residual bone to ensure that the implant is completely stabilized. This is considered to be one of the most critical factors for primary implant stability and parallelism and, subsequently osseointegration. Recently, improved initial implant stability is provided by advancement of surgical techniques, implant designs and surface treatments. This has led surgeons to extending simultaneous treatment option to patients with below 4 mm of residual bone height, despite the lack of much data. The purpose of this study was to retrospectively evaluate and compare the status of implants which are installed by delayed and simultaneous methods. Material and methods: The subjects were patients(121 patients, 278 implants) who had been operated with sinus lifting from 2003 to 2007 in Sun Dental Hospital. Lateral window approach with autograft and xenograft(1:1 ratio) were carried out for all sinus lifting. 4 types of implant were used. The mean follow up period was 26.3 months(19 - 58 months) in delayed group, and 22.8 months(18 - 43 months) in simultaneous group. Results: The survival rate of implant restoration of this study was 98.2% in delayed group and 91.7% in simultaneous group. In simultaneous group, wide-platform type implants showed 100% survival rate. The total average of marginal bone loss in radiographs was 0.96 ± 0.29 mm in delayed group and 1.02 ± 0.31 mm in simultaneous group. Conclusion: Simultaneous implantation with sinus lifting(below 4mm of residual bone height) could be predictable treatment.
