OBJECTIVES To study the accuracy of partially guided and fully guided templates applied to implant surgery of anterior teeth. MATERIALS AND METHODS Sixty patients who were scheduled to receive dental implant treatment in the anterior region were enrolled and randomly assigned to one of the following study groups (n = 20 each): routine implant-supported restoration treatment (control group, 30 implants), implant-supported restoration treatment using a partially guided template (test group 1, 36 implants), and implant-supported restoration treatment using a fully guided template (test group 2, 33 implants). The depth of implant was controlled for fully guided template. After implantation, planned implants and placed implants were superimposed using digital software, and the deviations (angular, coronal, apical, depth) were analyzed. Esthetic parameters were assessed at baseline, 6 months, and 1 year after the final restoration. Pink esthetic score (PES) and white esthetic score (WES) were respectively used to evaluate the soft tissue and restoration esthetic outcome. Each parameter of PES and WES is assessed with a 0-1-2 score with 2 being the best and 0 being the worst score. RESULTS There were significant differences in all of the deviation parameters between the control group, test group 1, and test group 2 (p
