In recent years, implants have been widely used in dental and oral fields. Many cases have been reported, and the indication of implants has been investigated. Many cases progressed well, but a few cases did not. The unfavorable cases of dental implant were reexamined by clinical observation. The results were as follows 1. The number of unfavorable cases of dental implant increased until 1992 but decreased after 1993. 2. The patients were 20 males and 29 females, and 83.7% of them were 40-69 years of age. 3. Pain was the most common chief complaint of the patients, followed by swelling. 4. Systemic diseases, including hypertension and diabetes mellitus, were noted in 63.3% of the patients. 5. Only 24.5% of the patients who visited our department were referred to us by the dentists who performed the implantations. 6. Right after implantation, 26.5% of the patients showed symptoms. 7. Treatment at our department was removal of most of the implants.
