摘要
背景:瓷贴面和全瓷冠是现阶段较好的前牙美学修复方式。目的:比较瓷贴面和全瓷冠在前牙修复中的效果。方法:收集63例(267颗)行前牙美学修复患者的临床治疗资料,其中采用IPS e.max铸瓷贴面修复者26例(138颗),采用氧化锆全瓷冠修复者37例(129颗),修复后采用目测类比评分法评价患者满意度;由修复专业医师对修复体颜色、形态、半透明度、边缘美观效果进行美学效果评价;于修复后1,3,6,12,24个月复诊,对修复体颜色匹配、修复体完整度、边缘适合度及牙龈反应进行临床效果评价,2年后评价两种修复方式成功率。结果与结论:两组修复后均有较高的患者满意度及医师评价。随访2年内,瓷贴面组有2例出现色彩偏差、2例瓷贴面脱落、1例冠折裂、2例出现明显牙龈红肿,全瓷冠组有1例全瓷冠折裂、4例明显牙龈红肿;2年后两组修复成功率比较差异无显著性意义(P>0.05)。结果表明瓷贴面和全瓷冠均具有较好的前牙美学修复效果。
BACKGROUND：Both porcelain laminate veneer and al-ceramic crowns are good choices for aesthetic restorations of anterior teeth at present. OBJECTIVE：To compare the effects of porcelain laminate veneer and al-ceramic crown in aesthetic restorations of anterior teeth. METHODS：Totaly 267 teeth of 63 patients with esthetic defect were included in this study, among which, 138 incisors were restored with IPS e.max porcelain laminate veneer and 129 incisors were restored with zirconia al-ceramic crowns. The final appearance of each restoration was evaluated by patient’s satisfaction on visual analogue scales and the esthetic effect was evaluated by professional prosthodontists. Evaluation criteria included color, shape, translucency and margin effects. Al restorations were evaluated at 1, 3, 6, 12 and 24 months after restoration in terms of the color match, the integrity of restoration, marginal adaptation and gingival condition. The success rates of two restorations were analyzed 2 years later. RESULTS AND CONCLUSION：The porcelain laminate veneers and zirconia al-ceramic crowns both had the higher patient’s satisfaction and esthetic effect assessment. According to the clinical evaluation, two veneers presented with a higher color difference, two veneers were debonded, one veneer was fractured and two tooth appeared to have obvious gingivitis symptom in the porcelain laminate veneer group; while one al-ceramic crown was fractured and four teeth appeared to have obvious gingivitis symptom in the al-ceramic crown group during 2-year folow-up observation. But there was no statistical difference in the success rate between the two groups
（P 〉 0.05）. The porcelain laminate veneers and al-ceramic crown both have a good esthetic effect in the restoration of anterior teeth.
