Abstract:
BACKGROUND:Dental implantation in maxilary 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 enroled. 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 folowed 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 maxilary esthetic zone and precisely localize the dental implantation site.
