两种黄金基底烤瓷全冠对牙周的影响分析

Effects of two auric-based porcelain complete veneer crown on periodontium

目的探讨金钯合金基底烤瓷全冠和金沉积基底烤瓷全冠对修复患者牙周状况的影响。方法在严格限定轴面外形、边缘适合性、牙周状况等方面的情况下,选取欲做上颌中切牙黄金基底烤瓷全冠22例男性患者(31颗),分别做金钯合金烤瓷修复(10例共16颗)和金沉积烤瓷修复(12例共15颗),调查其戴入时和戴入1年后的牙周状况。结果两种基底烤瓷全冠在修复前与修复1年后的GCF量及ALP、AST水平的差异有统计学意义(P<0.05);两种基底烤瓷全冠相比,GCF量及ALP、AST水平的差异有统计学意义(P<0.05)。结论牙体做黄金烤瓷全冠修复体后牙周组织将发生改变,而金沉积基底烤瓷全冠对牙周组织的影响小于金钯合金基底烤瓷全冠。

Objective To investigate the effects of Au-Pd-based porcelain complete veneer crown and porcelain crowns with galvanized frames on prosthetic patients＇ gingiva. Methods Under circumstances of strictly limiting crown contour,margin discrepancy and periodontal conditions, to select 22 male patients who wanted their upper central incisors auric-based porcelain complete veneer crown restored. To restore them with Au-Pd-based porcelain complete veneer crown（10 cases and total 16 teeth） and porcelain crowns with galvanized frames （12 cases and total 15 teeth）. The periodontal conditions were investigated before and one-year after restoration. Results After cementation of two kinds of crowns, both amount of GCF and level of AST and ALP increased significantly （P〈0.05）. While the effects of two groups on periodontium showed statistically significant change, too（P〈0.05）. Conclusion Periodontium will change after Au-based porcelain complete veneer crown restoration. The effects of porcelain crowns with galvanized frames are smaller than Au-Pd-based porcelain complete veneer crown on periodontium.
