Evaluation of the marginal precision of one‐piece complete arch titanium frameworks fabricated using five different methods for implant‐supported restorations

Abstract

The computer-aided procedures analyzed in the present study were able to produce a precision-fitting framework, with no significant differences among them and, at the same time, showed a greater precision compared with the traditional casting methods or with the use of prefabricated titanium copings. However, it should be noted that, even if group 2 frameworks were not as accurate as groups 3 and 4, cast titanium sovrastructures laser welded to prefabricated titanium copings showed significantly better marginal precision than the frameworks produced with the lost wax technique.
