It was proposed that technologies derived from CAD-CAM and computed tomography may be useful for flapless implant treatment procedures. The aims of this study were to validate the reliability of this concept in a prospective 12-month clinical study. Twelve patients with fully edentulous areas in their mandibles were included in this study. A total of 71 implants were inserted in interforaminal regions by use of a CAD/CAM drill template(), specially designed for flapless implant surgery. To assess the degree of pain and discomfort, the patients were examined at 2 days and 1 week after surgery. Patient satisfaction and implant functionality were further evaluated at follow-up intervals of 1, 3, 6, and 12 months postoperatively. One implant failed early in 1 patient. All of the other implants were in a good functional state throughout the study. The mean marginal bone loss after 1 year of follow-up was 0.3 mm (SD, 0.1) at center, 0.5 mm (SD, 0.1) at canine and 0.7 mm (SD, 0.2) at distal fixtures, respectively. Statistically, there was not significant differences among each sites(P>.05)The mean ISQ change after 1 year of follow-up was -1.05 (SD, 2.76) at center, -0.85 (SD, 2.59) at canine and -1.27 (SD, 2.18) at distal fixtures, respectively. This prospective pilot study showed that the use of CAD/CAM technology and flapless implant surgery may be considered reliable for fully edentulous mandible of patients.
