Abstract
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
<br> (P > 0.05). The porcelain laminate veneers and al-ceramic crown both have a good esthetic effect in the restoration of anterior teeth.关键词
