The purpose of this study is to explore the effectiveness of porcelain veneer technology on periodontitis in rats, so as to better guide clinical practice. Using 70 rats the periodontitis rat model was established. Porcelain veneer was used to repair the rat teeth. Follow-up evaluation of the curative effect was carried out at 2, 4, 6 and 8 weeks after operation, so as to gain a certain understanding of the treatment of periodontitis with porcelain veneer. The results showed that after porcelain veneer restoration, the teeth of periodontitis rats constructed by string ligation became wider, the space between teeth become smaller, the height of tooth bone decreased and the teeth were closely adhered to the gingiva. After operation, alveolar bone volume significantly increased (P<0.05). The follow-up results showed that the success rates of porcelain veneer were 100, 100, 97.5 and 95 % on the 2, 4, 6 and 8 week after operation. These results indicated that the ceramic veneer exerted a good restorative effect on rat teeth with periodontitis and has a high stability after operation. It is hence worth further investing future in clinical research
