Abstract

Compared with traditional full dentures, mandibular implant overdentures have the advantage in that good support and retention can be obtained even with two implants. When manufacturing a mandibular implant overdenture using two implants, it is important to place the implant in the correct position. The long-term prognosis of overdenture is good when two implants are placed in the direction vertical to the occlusal plane and parallel to each other at the canine position. However, it is difficult to place two implants in the correct position in edentulous patients, and if you use surgical guides in these cases, you can get help in placing the implants in a prosthetically advantageous position. This case, a 57-year-old male patient, came to our hospital with all upper and lower teeth removed due to periodontal disease. Therefore, the maxilla was restored with a traditional full denture and the mandible was restored with an implant overdenture using two implants, which resulted in satisfactory functional and esthetic results.
