Abstract

The outcomes of 153 ITI titanium plasma-sprayed screw implants were studied in 39 patients. Four implants were placed in the edentulous mandible between the mental foramina and used as support for a denture prosthesis. Thirteen implants in six patients had been lost during the follow-up time of 3 to 10 years (mean 5.6 years). The mean annual bone resorption was 0.25 mm (SD 0.29 mm; range 0 to 1.37 mm). Bone loss was smaller in patients with prosthetic loading applied within 7 postoperative days than in those with delayed prosthetic treatment. No evidence of bone loss was seen around 37 (26.4%) implants. The cumulative and overall success rates for titanium plasma-sprayed implants were 80.8% and 91.5%, respectively. The corresponding figures for the patients were 86.8% and 94.9%.

摘要

对39例患者中153颗ITI钛等离子喷涂螺钉种植体的治疗结果进行了研究。在下颌无牙区颏孔之间植入4颗种植体，用作义齿修复的支撑。在3至10年（平均5.6年）的随访期内，6例患者中的13颗种植体丢失。平均每年骨吸收为0.25毫米（标准差0.29毫米；范围0至1.37毫米）。术后7天内进行修复加载的患者骨丢失比延迟修复治疗的患者小。37颗（26.4%）种植体周围未见骨丢失迹象。钛等离子喷涂种植体的累积成功率和总体成功率分别为80.8%和91.5%。患者的相应数字分别为86.8%和94.9%。
