| Abstract | ||||
| Objective: To compare accuracy of surgical guided implant produced by intraoral scanner and desktop scanner in partially edentulous patients. Material and methods: ten partially edentulous patients were selected for implant placement . a total of 42 implants were placed in 4 males and 6 females (8 bilateral cases and 2 unliteral cases), with mean age of 47 years (42-55 years) were included. Patients were randomly divided into 2 equal groups (n=21 each): group one Surgical guide manufactured using intra oral digital impression. while group two Surgical guide manufactured using model cast scanning by desktop scanner. a pre cone beam CT scan was done and post CBCT was done after implant placement with the same parameters of pre CBCT. superimposition of CBCT scans was made. the linear and angular deviations of placed implants were measured. Results: In the intraoral scan group, the mean 3D angular deviation, platform 3D deviation, apical 3D deviation and vertical deviation were 2.5°, 0.7 mm, 1.1 mm and 0.6 mm, respectively. While in desktop scanner group the mean 3D angular deviation, platform 3D deviation, apical 3D deviation and vertical deviation were 2.6°, 0.1mm, 1.1mm and 1.1mm, respectively. Conclusion: effect of both scanning protocols on apical , coronal , vertical and angular deviations of placed implants is comparable , although intraoral scanner shows less vertical deviation.
