PURPOSE. In this study, the retrospective radiographic study is executed to evaluate amount of bone loss of various conditions in patients using customized abutment for 4 years of follow-up.

MATERIALS AND METHODS. The subjects of this study were implant fixed dental prosthesis using CAD/CAM customized abutments. CAD/CAM customized abutment and fixed dental prosthesis were manufactured by the Prosthodontics Department of Chosun University Dental Hospital from August 1, 2011 to July 31, 2012. Radiological assessments were performed on the patients who were treated by the fixed prosthodontics. After each treatment, a retrospective study was performed for a total of 4 years at 3 months, 6 months, 1 year, 2 years, 3 years, and 4 years.

RESULTS. As a result of the study, the customized abutment using CAD/CAM showed less bone loss than the results of existing research. There was no statistically significant differences at alveolar bone loss between splinting group and non-splinting group (respectively 0.27 mm, 0.5 mm). Also, there were statistically significant differences at alveolar bone loss in mx. anterior, mx. posterior, mn. anterior and mn. posterior part (respectively 1.37 mm, 0.39 mm, 0.00 mm, 0.30 mm).

CONCLUSION. The customized abutment using CAD/CAM showed less bone loss than the results of existing research, there were statistically significant differences at alveolar bone loss in implant positions.
