    Abstract
  •   Objective  To research the accuracy and position of implant placement between the and the simple template, and analyse the factors which affect the accuracy of implant placement.  Methods  Thirty patients were selected from January 2019 to January 2020 in the First Affiliated Hospital of Bengbu Medical College, who were randomly divided into groups A and B (15 patients in each group). Cone beam computed tomography (CBCT) images were taken before surgery, and Tooth Implant software was used to design the pre-operative plan. Implants were placed in group A using the digital surgical template, and implants were placed in group B using the simple template. All patients in the two groups were subjected to CBCT after the operation. Pre-operative and post-operative CBCT images were matched, and the deviations between the placed position and the planned were measured, including shoulder deviation, apical deviation, depth deviation and angle deviation. Final repair work was performed after 6 months, and the pink esthetic score (PES) and white aesthetic scores were given.  Results  We placed 51 implants in the 30 patients. Patients in group B received 25 implants. The deviation in group A was (0.57±0.11) mm in the shoulder, (0.78±0.35) mm in the apex, (0.36±0.19) mm in depth and (2.37±1.13)° in angle. The deviation in group B was (1.32±0.23) mm in the shoulder, (1.04±0.15) mm in the apex, (0.86±0.35) mm in depth and (7.24±1.37)° in angle. A significant difference in deviation index was found between the two groups (all P < 0.05). The PES in group A [(9.19±0.74) points] was significantly different from that in group B [(7.95±0.76) points] after 6 months (P < 0.05).  Conclusion  The digital surgical template for implant surgery may improve the precision of implantation in the anterior maxilla and the aesthetic restoration result. digital surgical template for implant surgery.
