文题释义:
种植体周围软硬组织健康的重要性:除了关系到种植义齿良好的美学外观,也直接影响到种植体的长期稳定性与使用寿命。软组织异常可能会导致骨吸收的发生,因此种植修复后龈组织保持健康连续的龈缘曲线十分重要。影响种植体周围软硬组织健康状况的因素,包括修复体材料类型、基台材料类型、边缘适合性及边缘位置等多个方面。
种植体修复基台的选择:对于牙龈非薄龈生物型患者,选择氧化锆基台或钛基台修复,牙龈颜色并无明显区别;对于牙龈薄龈生物型患者,即牙龈黏膜厚度不足2 mm时,氧化锆基台与钛基台修复在美观上的区别较明显;对于牙龈较薄患者,灰色钛基台被种植体周围牙龈覆盖,前牙区会透出钛基台的基底色,影响美观,而白色的氧化锆基台,存在不同的对光反应,可表现出较好的半透明性。同时对于笑线较高的患者来说,没有金属边缘的暴露,氧化锆基台毋容置疑有着更大的美学优势。
 
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(P < 0.05)。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: With the increasing aesthetic pursuit of patients, an aesthetic abutment with certain strength has aroused people’s attentions either in the anterior or posterior tooth repair.
OBJECTIVE: To evaluate the effects of titanium abutment and zirconia abutment on peri-implant tissue in anterior teeth.
METHODS: A total of 40 anterior teeth from 34 patients were selected and received single crown restoration with Ankylos implants. Among them, titanium abutments were used in 20 teeth, and zirconia abutments in the other 20 teeth. All the patients were re-visited at 12 months after crown restoration. Peri-implant marginal bone resorption length (MBL), periodontal probing depth (PD), modified plaque index (mPLI), modified sulcus bleeding index (mSBI), and papilla index (PP) were detected; patient satisfaction investigation was carried out; and aesthetic assessment was done based on the pink esthetic score (PES).
RESULTS AND CONCLUSION: There were no differences between two groups in MBL, PD, mPLI, mSBI, PP. Patients in both groups were satisfied with the treatment outcomes with insignificant difference (P > 0.05). The PES value in the zirconia abutment group was significantly higher than that in the titanium abutment group (P < 0.05). Overall, titanium and zirconia abutments show the similar effects on the peri-implant tissues and both can achieve good clinical outcomes. However, zirconia abutments have certain advantages in the aesthetic restoration for anterior teeth, and further investigation on long-term effects is warranted.
