【摘要】：目的:探讨种植体支持套筒冠式固定可摘修复体在无牙颌中的应用特点,评价其临床效果。方法:12例无牙颌患者采用种植体支持套筒冠式固定可摘修复,总共植入种植体82枚,完成上颌无牙颌修复5例,下颌无牙颌修复7例。其中4例采用全瓷结构修复,8例采用钴铬合金烤瓷修复。随访1~3年(平均约21个月),通过临床检查、影像学检查及患者满意度评估修复效果。结果:截至2013年8月,1枚种植体松动。1例钴铬合金烤瓷冠崩瓷,12例修复体固位、稳定性均良好,未见修复体折断、松动现象。最近复查时,1例患者的2枚种植体出现边缘骨吸收,分别约为0.8、1.0 mm。其余种植体边缘骨吸收不明显。结论:种植体支持套筒冠式固定可摘修复应用于无牙颌患者,近期临床效果可靠,满意度高,但远期效果仍需进一步观察。
[Abstract]:Objective: to evaluate the clinical effect of implant-supported sleeve crown removable prosthesis in edentulous jaw. Methods: a total of 82 implants were implanted in 12 patients with edentulous jaws. 5 cases were maxillary edentulous and 7 cases mandibular edentulous mandible. Among them, 4 cases were repaired with all-ceramic structure and 8 cases with cobalt-chromium alloy porcelain. The patients were followed up for 1 ~ 3 years (mean 21 months), and the effect of repair was evaluated by clinical examination, imaging examination and patient satisfaction. Results: as of August 2013, one implant was loosened, one case was disintegrating porcelain with cobalt-chromium alloy ceramic crown, 12 cases were retained, and the stability was good, no fracture or loosening of the prosthesis was observed. In the most recent reexamination, two implants developed marginal bone resorption in one patient, about 0.8 mm., respectively. The marginal bone resorption of the other implants was not obvious. Conclusion: the removable implant support sleeve crown fixation can be used in edentulous jaw patients. The short-term clinical effect is reliable and the satisfaction is high, but the long-term effect still needs to be further observed.
