摘要

Immediate provisionalization with definitive customized abutment is beneficial for maintenance of the marginal bone and surrounding gingival tissue. To fabricate the definitive customized abutment before implant surgery, however, is of considerable uncertainty because it is difficult to place the implant exactly in the position and angulation as planned. This report describes a case in which computer-guided immediate implant placement and provisionalization with definitive CAD/CAM abutment was applied with a stereolithographic surgical guide. Due to the relatively proper implant position provided by this approach, the treatment process proceeded relatively smoothly, and the clinical outcomes with regard to esthetics and function were satisfactory. The technique used saved a lot of chair time, and the postsurgical discomfort of the patient was extremely low; therefore, implementation of the technique in similar clinical situations may well be appropriate.
