【摘要】:目的:评价碳纤维增强"All-on-4"即刻修复体的临床效果。方法:根据纳入标准及排除标准,收集2008年4月至2014年3月在北京大学口腔医学院种植中心应用"All-on-4"技术完成的上颌或下颌无牙颌种植即刻修复体,根据有无碳纤维增强分为对照组和增强组。2008年4月至2012年12月共纳入对照组60例患者(男32例,女28例),完成即刻修复体71例(上颌28例,下颌43例);2013年1月至2014年3月共纳入增强组23例患者(男13例,女10例),完成即刻修复体28例(上颌9例,下颌19例)。记录修复体相应患者的详细病例资料,以永久修复日期为截点,观察即刻修复体在使用期间内有无折裂,增强组即刻修复体组织表面有无纤维暴露及口内黏膜情况,扫描电镜观察碳纤维与树脂交界面的结合情况。结果:对照组和增强组即刻修复体在患者年龄[(57.3±10.1)岁vs.(55.1±11.4)岁]、性别(男32例和女28例vs.男13例和女10例)、上/下颌位(上颌28例和下颌43例vs.上颌9例和下颌19例)、术前即刻拔牙病例数(46例vs.23例)、修复体平均使用时间[(7.8±1.3)个月vs.(7.5±1.1)个月]及即刻修复体对颌牙列状态分布方面差异无统计学意义(P0.05)。对照组71例即刻修复体共发生21例(29.6%)基托折裂,碳纤维增强组28例即刻修复体,在行使功能期间未发现有修复体折裂,增强组即刻修复体折裂率显著性低于对照组(P=0.001),且修复体组织表面均未见碳纤维暴露,口内黏膜正常无刺激。扫描电镜可见碳纤维与树脂之间结合相对紧密,纤维表面可见黏附的树脂颗粒。结论:对"All-on-4"即刻修复体基托树脂进行碳纤维增强,能减少修复体折裂的发生,效果可靠。
[Abstract]:Objective: to evaluate the clinical effect of carbon fiber reinforced "All-on-4" immediate prosthesis. Methods: according to the inclusion criteria and exclusion criteria, the immediate prostheses of maxillary or mandibular edentulous implants were collected from April 2008 to March 2014 in the Center of Dental Medicine, Peking University, using "All-on-4" technique. From April 2008 to December 2012, 60 patients (32 males and 28 females) were included in the control group, and 71 cases (28 maxillary, 43 mandible) were performed immediate prosthesis. From January 2013 to March 2014, 23 patients (13 males and 10 females) were included in the enhanced group, and 28 cases (9 maxillary, 19 mandible) were performed immediate prosthesis. The detailed case data of the corresponding patients were recorded, and the date of permanent repair was taken as the cut-off point to observe whether the immediate prosthesis had fracture or not, and whether the tissue surface of the immediate prosthesis in the enhancement group was exposed to fibers and the mucous membrane in the mouth. The interface between carbon fiber and resin was observed by SEM. Results: the age of the patients with immediate prosthesis in the control group and the enhanced group [(57.3 卤10.1) years old vs. (55.1 卤11.4) years old] and sex (32 males and 28 females vs.) were found. 13 males and 10 females, upper / mandibular position (28 maxillary and 43 mandibular vs.) There were 9 cases of maxilla and 19 cases of mandible, and 46 cases of vs.23 were extracted immediately before operation. There was no significant difference in mean service time (7.8 卤1.3) months vs. (7.5 卤1.1) months and immediate prosthesis in the distribution of maxillary dentition status (P0.05). In the control group, 21 cases (29.6%) of the immediate restoration occurred in the control group, and 28 cases in the carbon fiber reinforced group. No fracture was found during the exercise of the function. The fracture rate was significantly lower in the enhancement group than that in the control group (Pn0.001), and no carbon fiber exposure was found on the surface of the prosthesis, and there was no irritation in the oral mucosa. Scanning electron microscope showed that carbon fiber and resin bonded relatively closely, the surface of the fiber adhesive resin particles can be seen. Conclusion: carbon fiber reinforcement of "All-on-4" immediate prosthesis base resin can reduce the fracture rate and the effect is reliable.
