【摘要】：背景:随着患者不断提升的美观要求,不管是前牙还是后牙修复,有一定强度且美观的基台材料越发引起人们的关注。目的:评价前牙区钛基台与氧化锆基台修复对种植体周围组织的影响。方法:选择行前牙区种植修复患者34例(40颗牙齿),植入Ankylos系统种植体并完成单冠修复,其中20颗采用钛基台,另20颗采用氧化锆基台,冠修复后12个月复诊,通过影像学评价种植体周围骨吸收量,同时检测牙周探诊深度、改良菌斑指数、改良龈沟出血指数及龈乳头指数,调查患者对种植修复的满意度,并应用红色美学评分标准进行美学评价。结果与结论:钛基台修复组与氧化锆基台修复组牙周探诊深度、改良菌斑指数、改良龈沟出血指数、龈乳头指数比较差异无显著性意义;两组修复后12个月的种植体周围骨吸收量无差异;两组患者对种植修复的满意度均较高,组间比较无差异;氧化锆基台修复组的红色美学评分高于钛基台修复组(P0.05)。结果表明,钛基台与氧化锆基台修复对种植体周围软硬组织的影响无差异,均能获得较好的临床修复效果,但氧化锆基台在前牙区美学修复存在一定优势,长期效果有待于进一步观察。
[Abstract]:Background: as patients continue to improve their aesthetic requirements, both anterior and posterior teeth are restored, More and more attention has been paid to the material of strong and beautiful abutment. Objective: to evaluate the effect of titanium abutment and zirconia abutment restoration on the surrounding tissue of the implant. For example, 40 teeth were implanted with Ankylos system implants and were repaired with single crown. Twenty of them were treated with titanium base and the other 20 with zirconia. The bone resorption around the implant was evaluated by imaging, and the depth of periodontal exploration and the improved plaque index were measured. Modified gingival sulcus haemorrhage index and gingival papilla index were used to investigate patients' satisfaction with implant restoration, and aesthetic evaluation was carried out by using red aesthetic score. Results and conclusion: periodontal probing depth of titanium and zirconia base abutment repair group was evaluated. There was no significant difference in plaque index, modified gingival sulcus bleeding index and gingival papilla index between the two groups. There was no difference between the two groups, and the red aesthetic score of the zirconia base restoration group was higher than that of the titanium base platform restoration group (P 0.05). The results showed that there was no difference in the effect of the titanium base and zirconia base restoration on the soft and hard tissue around the implant. But there are some advantages in aesthetic restoration of Zirconia abutment in anterior teeth, and the long-term effect needs further observation.
