| Abstract | ||||
| The aim of this study is to evaluate the accuracy of implant placement using implant surgical guide by CBCT cast scan. Patients and methods: seven resin surgical guide models were used in this study. Implant position was virtually planned using 3D planning software. Surgical guides were designed on the software and exported in STL format. Ten implants were placed. The 3D position of the planned and placed implants, in terms of the linear deviations of the implant head and apex and the angular deviations of the implant axis, was compared by superimposing the pre- and postoperative CBCT using software. Data showed parametric distribution so; it was represented by mean and standard deviation (SD) values. Result: Angular deviation was 2.38 ± 0.37 degree. Coronal deviation of Implant was 0.49 ± 0.12 mm. Apical deviation of implant Apex was 1.28 ± 0.15 mm, although the implant position was slightly different than the planning but, there was no statistically significant difference. Conclusion Implant surgical guide fabricated with CBCT cast scan has accepted accuracy and it is less costly technique with accepted accuracy. | ||||
