Abstract: Objective: To evaluate the clinical outcome of full arch implant placement using digital pioneer drilling guide and full guide. Methods: The present study was conducted on 15 patients who received full arch implant placement in the Department of Implantology School and Hospital of Stomatology, Tianjin Medical University between October 2016 to October 2020. There were 6 males and 9 females aged (57.5±6.3) years. There were 6 cases of complete dentition loss and 9 cases of single arch dentition loss. For specific surgical site, 11 were maxilla edentulous and 10 were mandible. 11 cases were conducted with the help of digital pioneer drilling guide and the other 10 cases were accomplished using digital full guide. A total of 121 implants were placed. Three dimensional positions of implants were compared pre- and post-surgery to assess the accuracy of these digital guides. The accuracy of the two digital guides and the duration of implant operation were evaluated. Results: 121 implants were placed under digital guide. One implant disloaded three months after provisional prosthesis and the patient was subsequently loaded on the rest 5 implants. All other cases were finished according to the original plan and no failure happened during the review period. For maxillary and mandible fully guided implant placement, the implant insertion axial direction angulation, and cervical and apical deviation were significantly smaller than digital pioneer drilling guided surgery (P<0.05). The operation time of patients with full digital guide was significantly shorter than that of patients with pioneer drill guide, no matter in maxilla or mandible. Conclusion: Full guided system is more accurate and reduced the operation time in contrast to pioneer drilling guided for full arch implant placement.
