The endodontic endosseous implant has been used to stabilize the mobile tooth which is affected by periodontal disease or trauma. We treated the luxated teeth of the anterior lower region using endodontic endosseous implants ten years ago. The disturbance of the masticatory function and esthetic problems of these teeth were not recognized. However, inflammation of the periapical region has reoccurred due to insufficient bonding of the implant to the canal walls. Furthermore, plaque control by the patient was not performed perfectly due to absorption of the alveolar bone and roots. Another kind of dental implant, Brånemark implant system, was installed into the mandible after removal of the endodontic endosseous implanted teeth. The occlusal function was restored completely, and mobility of the Brånemark implant was not observed.
When an implant does not lead to satisfactory progress for a long time, another kind of the dental implant should not be installed due to resorption of the alveolar bone. We recommend that if the inflammation surrounding the implant occurs occasionally and plaque control by the patient is not achieved sufficiently due to resorption of the alveolar bone, the replacement with a more predictable dental implant should be done as soon as possible.
