dc.description.abstract Background: Computer-aided dental implant placement seems to be useful for placing implants by using a flapless approach. However, evidence supporting such applications is scarce. the aim of this study is to evaluate the accuracy of and complications that arise from the use of selective laser sintering surgical guides for flapless dental implant placement and immediate definitive prosthesis installation.Methods: Sixty implants and 12 prostheses were installed in 12 patients (four males and eight females; age range: 41 to 71 years). Lateral (coronal and apical) and angular deviations between virtually planned and placed implants were measured. the patients were followed up for 30 months, and surgical and prosthetic complications were documented.Results: the mean +/- SD angular, coronal, and apical deviations were 6.53 degrees +/- 4.31 degrees, 1.35 +/- 0.65 mm, and 1.79 +/- 1.01 mm, respectively. Coronal and apical deviations of < 2 mm were observed in 82.67% and 58.33% of the implants, respectively. the total complication rate was 34.41%; this rate pertained to complications such as pulling of the soft tissue from the lingual surface during drilling, insertion of an implant that was wider than planned, implant instability, prolonged pain, midline deviation of the prosthesis, and prosthesis fracture. the cumulative survival rates for implants and prostheses were 98.33% and 91.66%, respectively.Conclusions: the mean lateral deviation was < 1.8 mm, and the mean angular deviation was 6.53 degrees. However, 41.67% of the implants had apical deviation > 2 mm. the complication rate was 34.4%. Hence, computer-aided dental implant surgery still requires improvement and should be considered as in the developmental stage. J Periodontol 2012;83:410-419. en
