Passive definitive fit of bar-supported implant overdentures.

ABSTRACT

A passive fit is an important prerequisite for implant-supported prostheses. It limits the amount of stress transferred to the bone-implant interface and ensures long-term osseointegration. A simplified technique is proposed for the fabrication of passive bar-supported implant overdentures. The use of titanium industrial components enhances the precision of fit, and the passivity is achieved with an intraoral luting sequence and laser welding. The method is quick and standardized, and does not require sophisticated steps. This article shows the results of 7 cases 18-24 months (mean 21.4) after the loading of cases.
