Application of digital prosthesis in the repair of palatal fistula in rabbits / 中国组织工程研究

ABSTRACT

BACKGROUND: Digital impression technology has been widely used in the oral field. Compared with traditional impression technology, it is more convenient and accurate. OBJECTIVE: To explore the application of digital prosthesis for repairing palatal fistula in rabbits. METHODS: The rabbit models of palatal fistula were established by surgery. One month later, 10 rabbit models of palatal fistula were scanned by digital intraoral scanning system. The medical silicone rubber prosthesis for palatal fistula was manufactured by digital impression technology and digital design. After wearing the prosthesis, SUN LB, LAN YY, ZHOU HY, HUY. Application of digital prosthesis In me repair of palatal fistula In rabbits.  Zhongguo Zuzhi Gongcheng Yanjiu. 2020;24(14)2192-2196. DPI10.3969/j.issn.2095-4344.2228 the accuracy, retention and sealing properties of the prosthesis were examined. The study was approved by the Laboratory Animal Ethical Committee of Hospital of Stomatology, Southwest Medical University. RESULTS AND CONCLUSION: After digital prosthesis repaired palatal fistula, the accuracy, retention and sealing properties of the prosthesis were good. To conclude, the digital prosthesis for palatal fistula repair by digital impression technology achieves accurate repair, and has certain clinical values.
