目的对Cermage聚合瓷高嵌体和多面嵌体修复根管治疗后大面积缺损的磨牙与前磨牙临床疗效进行评价。方法选择2013年3—12月大连医科大学附属第一医院口腔科就诊的52例患者的54颗患牙,完善根管治疗后,按照嵌体预备原则行Ceramage聚合瓷高嵌体和多面嵌体修复,患者戴入修复体后即刻和1年后随访,参照美国公共健康协会(USPHS)的修正标准制定此次研究的嵌体评估标准。结果修复后即刻检查修复体固位、边缘密合性、牙龈邻接关系以及修复体颜色匹配程度等,44颗聚合瓷嵌体试戴后参照各项嵌体评估标准均达到A级,修复效果满意;10颗修复体颜色与牙齿稍有差异,颜色匹配程度达到B级,修复体颜色的匹配性达81.5%。修复后1年随访率94.2%,失访3例;1年后再次检查评估,51颗修复体表面视诊、探诊均光滑,未出现粗糙面,边缘密合度好,未出现继发龋、牙体折裂,修复效果达到A级;3例修复体边缘有轻微着色,修复效果达到B级;9例修复体与牙体颜色和透明性有差异但不明显,修复效果达到B级;3例修复体与邻牙出现轻微食物嵌塞,但牙线可清除,牙龈稍有红肿,修复效果达到B级;36例修复体各项评估标准满意程度与可接受程度均达到100%。结论Ceramage聚合瓷高嵌体和多面嵌体修复是用于后牙根管治疗后牙体缺损的一个优先考虑的选择。
Objective To evaluate the clinical effects of Cermage polymeric inlays and multiple premolars in the treatment of large defects after root canal treatment. Methods From March to December 2013, 54 patients with 52 teeth diagnosed in Department of Stomatology, the First Affiliated Hospital of Dalian Medical University were enrolled in this study. After root canal therapy, Ceramage polymeric inlays and inlays The intimacy criteria for this study were established immediately following the patient’s insertion into the prosthesis and 1 year after the visit, with reference to the revision of the US Public Health Association (USPHS). Results After the repair, the prosthesis retention, marginal adhesion, gingival abutment and the color matching degree of the prosthesis were examined immediately. All the 44 inlays were tested with reference to the evaluation criteria of inlays to achieve Grade A, the repair effect was satisfactory The color of the 10 prostheses was slightly different from that of the teeth. The color matching degree reached grade B, and the color matching of the prosthesis reached 81.5%. After one year of follow-up, the rate of follow-up was 94.2% and 3 cases were lost to follow-up. After one year, they were re-examined and evaluated. The surface appearance of 51 prostheses was visualized. Tooth fracture, the repair effect to A grade; 3 cases of prosthetic edge slightly colored, the repair effect to B grade; 9 cases of prosthesis and dental body color and transparency are different but not obvious, the repair effect to B grade; 3 A slight food impaction was found in the prosthesis and the adjacent teeth. However, the floss was cleared and the gums were slightly red and swollen, and the repair effect reached Grade B. The satisfaction and acceptability of all the 36 prostheses were all 100%. Conclusions Ceramage Polycrystalline Inlays and Inlays Restoration is a preferred option for tooth defects after posterior root canal therapy.
