数字化快速成型牙种植导板辅助修复上前牙种植：12个月随访

Digital rapid prototyping implant template assists anterior tooth restoration in maxillary esthetic zone: a follow-up of 12 months

BACKGROUND: Dental implantation in maxillary esthetic zone is difficult to achieve desired outcomes. OBJECTIVE: To observe the feasibility of digital rapid prototyping implant template for anterior implantation.METHODS: Eighty patients scheduled to receive anterior implant treatment were enrolled. According to the wishes of patients, they were divided into two groups, with 40 cases in each group, and were given routine implant treatment (control group) and digital rapid prototyping template-aided dental restoration (observation group). After implantation, the X-axis, Y-axis and Z-axis errors of the two groups were measured, and the patients were followed up for 12 months.RESULTS AND CONCLUSION: After implantation, the errors of X, Y and Z axes in the observation group was significantly lower than those in the control group (P < 0.05); at 24 hours after implantation, patients in the two groups showed good appearance of the anterior tooth with no dental prosthesis loosing. Imaging examinations in the two groups showed no obvious bone resorption. These findings indicate that the aid therapy using digital rapid prototyping can obtain satisfactory therapeutic effect on anterior tooth restoration in the maxillary esthetic zone and precisely localize the dental implantation site.
