Abstract
AIM: To compare the maintenance requirements of implant supported fixed prostheses opposed by implant supported fixed prostheses natural teeth or complete dentures.
METHOD: The maintenance requirements were obtained by examining the dental records of 15 people, of whom 6 were edentulous in both arches and 9 edentulous in one arch. The results were compared to those obtained from 22 edentulous people in whom implants had been used in the mandible (control group). All the patients were treated with Nobel Biocare implants using standard implant and prosthetic protocols.
RESULTS: The main maintenance requirement was the need to repair part of the superstructure. The artificial teeth and the acrylic resin had to be repaired on 44 occasions in the group with implants in both jaws and 14 occasions in the group with implants opposed by natural
teeth. This compared with 2 occasions in the control group. Similarly the group with implants in both jaws were more likely to fracture the gold alloy framework, an event which occurred on 6 occasions. The Kruskal- Wallis one way analysis of variance on ranks was used
to identify significant differences and Dunn’s method of All Pairwise Multiple Comparison Procedures was used to distinguish which group differed from the other. The group with implants in both jaws was significantly different to the other two groups in relation to the higher incidence of fracture of the teeth and acrylic resin superstructure
(p<0.0001) and fracture of the gold alloy framework (p = 0.0002).
CONCLUSION: The maintenance requirements of implant supported fixed prostheses opposed by implant supported fixed prostheses are much greater than when opposed by natural teeth or complete dentures.
