摘要
目的:对比玻璃纤维桩与铸造金属桩应用于牙体缺损修复的疗效.方法:纳入牙体缺损患者93例(142个牙),其中47例(72个牙)用玻璃纤维桩修复,46例(70个牙)用铸造金属桩修复.修复后24个月随访,观察修复体松动脱落、桩钉折断、颜色匹配、边缘密合、修复体完整等情况,并检测牙周碱性磷酸酶(ALP)水平及牙周袋深度(PD).结果:与修复前相比,修复24个月后,ALP水平铸造金属桩组明显上升(P＜0.05),玻璃纤维桩组则无明显变化(P＞0.05);两组的PD在修复前后均无统计学差异(P＞0.05).玻璃纤维桩组修复体颜色匹配情况及边缘密合度明显优于铸造金属桩组(P＜0.05);桩核冠损坏,玻璃纤维桩组3例,铸造金属桩组22例,两组修复成功率分别为98.61％、88.57％ (P ＜0.05).结论:玻璃纤维桩修复牙体缺损,较铸造金属桩更美观,并具有更加突出的力学性能、更高的修复成功率及更轻的牙周影响.
Abstract
AIM:To compare the effects of glass fiber post with cast metal post in the restoration of tooth defect.MEHODS:142 teeth with tooth defect in 93 patients were repaired by implementation of glass fiber post (72 teeth in 47 cases) and metal casting post (70 teeth in 46 cases) respectively.After the completion of the repair operation,the patients were followed-up for 24 months,the prosthesis loosening off and post nail breakage,color matching,edge fitting and restoration completeness were observed,periodontal alkaline phosphatase(ALP) level was measured.RESULTS:24 months after repair,glass fiber group showed better restoration color matching and edge fitting than metal casting group (P ＜ 0.05);post nuclear crown damage was found in 3 cases in glass fiber group and 22 cases in metal casting group (P ＜ 0.05).The success rate of glass fiber group and metal casting group was 98.61％ and 88.57％ respectively(P ＜ 0.05).24 months after repair,ALP level in metal casting group increased (P ＜ 0.05),in glass fiber group did not significantly changed (P ＞ 0.05).CONCLUSION:Glass fiber post is more effective than cast metal post in the restoration of tooth defect.
