目的探讨黏结固位与螺丝固位在后牙种植义齿单冠修复中的应用效果。方法选取柘城县中西医结合医院后牙种植患者为研究对象,共计110例共154枚种植体。其中72枚采用螺丝固位,82枚采用黏结固位。随访2年并比较两种治疗方式下改良菌斑指数,种植体周围骨吸收量,患者满意度,并发症等,分析两种治疗方式的特点。结果 82枚黏结固位种植体,无支架断裂或桥体松动发生,4枚烤瓷冠瓷层出现裂痕或破裂。72枚螺丝固位种植体,8枚螺丝松动,12枚烤瓷冠瓷层出现裂痕或破裂。1年的骨吸收量分别(0.439±0.037),(0.428±0.012)、2年的骨吸收量分别为(0.535±0.040),(0.519±0.027),两种固位方式的改良菌斑、改良出血指数,固位功能,咀嚼功能,美观程度,舒适程度,总满意度评分上无显著性差异。结论螺丝固位与黏结固位具有相似的临床效果,均为后牙种植义齿单冠修复的可靠治疗方式。
Objective To investigate the effect of adhesive fixation and screw fixation on single crown restoration of posterior dental implant prosthesis. Methods Patients of posterior teeth in Integrative Medicine Hospital of Tancheng County were selected as the research object, a total of 110 cases of 154 implants. Of these, 72 are screwed and 82 are bonded. Followed up for 2 years and compared the two methods of treatment to improve the plaque index, bone resorption around the implant, patient satisfaction, complications, analysis of the characteristics of the two treatment methods. Results 82 cemented implants, no stent fracture or loose bridge occurred, four ceramic porcelain crown cracks or rupture. 72 screws retainer, 8 screws loose, 12 porcelain crown porcelain cracks or rupture. The bone resorption in one year was (0. 439 ± 0 037) and (0 428 ± 0 012) respectively, and the bone resorption in 2 years were (0.535 ± 0.040) and (0.519 ± 0.027), respectively. Bleeding index, retention function, masticatory function, aesthetic appearance, comfort level and total satisfaction score had no significant difference. Conclusion The screw fixation and adhesive fixation have similar clinical effects, all of which are the reliable treatment for the restoration of posterior denture single crown.
