Clinical application of dynamic navigation system in autotransplantation of teeth
Objective:To evaluate the feasibility of the application of DNS in autotransplantation of teeth,by compa-ring the dynamic navigation system(DNS)guided autotransplantation of teeth and 3D print-assisted autotransplantation of teeth.Methods:A total of 40 cases of autotransplantation of teeth completed in the Oral surgery Department of the Affiliated Stomatology Hospital of Xi'an Jiaotong University from March 2023 to June 2024 were collected and randomly divided into DNS group and 3D group.The former performed autotransplantation of teeth guided by DNS,and the latter performed auto-transplantation of teeth assisted by 3D printing.The time of alveolar socket preparation,the number of fitting attempts of the donor tooth,the operation time and the transplant success rate of the two groups were analyzed respectively.Results:The time of alveolar socket preparation,the number of fitting attempts of the donor tooth and the operation time in DNS-guided auto-transplantation of teeth were significantly better than those in 3D printing group(P<0.05),and there was no statistical differ-ences in transplant success rate(P>0.05).Conclusion:DNS can accurately complete alveolar socket preparation through preoperative digital personality design,decrease extra-alveolar time,simplify the overall surgical process,reduce the number of adjustment of transplanted teeth,and improve the efficiency and accuracy of surgery.Therefore,this technique is suitable for autotransplantation of teeth and recommended for clinical popularization.
