Clinical Evaluation of Osseointegrated Implant in Elderly Patient

Abstract

POI 2 Piece Implant ^®having been applied to the Implant therapy clinically since 1991 has hitherto raised a successful result for the young through old broadly.
We herewith report this time of our clinically examination made for eldery patient having been kept under Implant therapy for a long period.
The patient was an old man of 78 years old whose alveolar ridge was found absorbed remarkably, resulting in unfitness of full denture. So he wanted to receive the Implant therapy for him. He was treated of anterior mandible by inserting 4 of POI 2 Piece Implant ^®32-14F in March, 1992. But I of 4 Implants had failed during healing period. Bioceram ^®Implant had been inserted at the positions 32 and 42 each additionally. After the healing period had passed, the cement-fixing type of prosthesis had been loaded there. Although having been kept preferable of his condition for prognosis after setting prosthesis, he visited our dental office, chief complaint of pain in the base of cantilever on the both sides in 1998. Therefore, we removed the cantilever and set end-free denture. He visited our clinic again in April, 2002, appealing for him to become hard to remove the end-free denture on account of abnormal shrinking of the muscle of his right arm. As I also found his super structure unstable due to loosing of its straight post, I removed the super structure, repaired the used end-free denture by adding tooth thereto, and modified it into the overlay denture using the ball attachment on June 10, 2002. After setting new overlay denture to the patient October 5 2002, no such troubles as swelling and pain bade been eliminated completely, and the denture has been kept good stably since then, keeping good condition.
As shown above in a case, I think it would be necessary to take into consideration modification of design of prosthesis for improvement of cleaning efficiency as well as simplification of prosthesis and easier recoverability of denture as the edge of patients is becoming higher and higher in these years.
