| Abstract | ||||
| Background: Zygomatic implants provide as an alternative to extensive grafting techniques for addressing atrophic posterior maxilla. The placement of zygomatic implants is technically complex, often leading to severe problems and various prosthetic difficulties due to inaccurate positioning. Virtual surgical planning enhances the precise placing of zygomatic implants and promotes advantageous prosthetic results. Aim of the study: This study was conducted with the aim of evaluating the three-dimensional morphological and functional accuracy of virtual surgical planning (VSP) guided zygomatic implant placement. Materials and methods: Zygomatic implants were utilized to support the posterior areas of the rehabilitation. The implant was placed by transferring the preoperatively planned position to the surgical field utilizing cone beam computed tomography (CBCT) and an implant planning software to create a 3D-printed surgical guide. A three-dimensional radiographic examination was carried out immediately to assess the precision of the virtual surgical planning. Results: A total of eight implants in this study. In all patients two zygomatic implants were inserted, one on each side. The mean linear coronal deviations between virtually planned and actually placed implants was 1.49 ± 0.53, which ranged from 1.01 – 2.90. The mean linear apical deviations between virtually planned and actually placed implants was 2.08 ± 0.55, which ranged from 2.89 – 6.89. The mean angular deviations between virtually planned and actually placed implants was 2.08 ± 0.55, which ranged from 2.89 – 6.89.
