An oral implant for partially or fully edentulous patients is very useful for the reconstruction of occlusal function. Recently it has become widely used by many practitioners, and quite a few of these implant therapies have been reported. On the other hand, reports of failure of clinical therapeutic approaches with oral implant are relatively few. We report 30 failed implants in 20 patients. This investigation is based on clinical evaluations of patients who visited our clinic over the last 14 years. The results are as follows:
1. The patients were 11 males and 9 females. The ages of the patients ranged from 22 years to 80 years.
2. The chief complaint of these patients was swelling and pain at the implant site. This was the most common complaint (7 cases), followed by mobility of the fixture and pain (2 cases), mobility of the fixture (2 cases), pain (2 cases), fracture of the fixture (2 cases), altered sensation (2 cases), sensory disturbance (2 cases), and no complication (1 case).
3. Materials and the type of implant:metal implant (10 cases), alumina ceramic implant (10 cases), and endosteal implant (18 cases) are the most frequent, followed by endodontic and endosteal implant (1 case), and subperiosteal implant (1 case).
4. The major etiologic factors leading to failure are classified into three types:local infection (13 cases), impaired healing (4 cases), and overload (3 cases).
5. Thirteen patients complained immediately and wanted to remove the implant. Two patients had no complaint at their first consultation.
