目的
本研究的目的是评价191个瓷贴面的临床质量，并探讨牙龈反应在一个长期的调查。
材料和方法
临床检查由两名经校准的检查员按照修改的加州牙科协会/Ryge标准进行。此外，边缘指数，乳头出血指数，龈沟探诊深度，并增加牙龈退缩记录。形成两个年龄组以评估佩戴时间对临床结果的影响。使用Kaplan-Meier生存估计方法、卡方检验和Kruskal-Wallis检验对结果进行统计学评价。
结果
失败率为4%，其中6/7的失败发生在贴面与牙本质部分粘结时。99%的边缘完整性可接受，63%的边缘完整性被评为极好。17%的患者存在浅表边缘变色。31%的患者发现轻微的边缘退缩，25%的患者发现探诊出血。
结论
瓷贴面提供了一个可预测的和成功的治疗方式，保留了最大的健全的牙齿结构。只有当贴面部分粘结到牙本质上时，才存在失败的风险增加。估计10年内的生存概率为91%。
PURPOSE
The objective of this study was to evaluate the clinical quality of 191 porcelain laminate veneers and to explore the gingival response in a long-term survey.
MATERIALS AND METHODS
The clinical examination was made by two calibrated examiners following modified California Dental Association/Ryge criteria. In addition, margin index, papillary bleeding index, sulcus probing depth, and increase in gingival recession were recorded. Two age groups were formed to evaluate the influence of wearing time upon the clinical results. The results were statistically evaluated using the Kaplan-Meier survival estimation method, Chi-squared test, and Kruskal-Wallis test.
RESULTS
A failure rate of 4% was found. Six of the total of seven failures were seen when veneers were partially bonded to dentin. Marginal integrity was acceptable in 99% and was rated as excellent in 63%. Superficial marginal discoloration was present in 17%. Slight marginal recession was detected in 31%, and bleeding on probing was found in 25%.
CONCLUSION
Porcelain laminate veneers offer a predictable and successful treatment modality that preserves a maximum of sound tooth structure. An increased risk of failure is present only when veneers are partially bonded to dentin. The estimated survival probability over a period of 10 years is 91%.
