The Relevance of a New Generation of Monobloc Posts and Impression Copings for Implant-supported Fixed Partial Dentures: A 2-year Clinical Prospective Study With the FM-Clip System on EVL Implants (SERF)
The use of monobloc posts for implant-supported fixed partial dentures is interesting for biomechanical and biological reasons, but it suffers from a lack of precision during the impression phase. The use of a new generation of monobloc posts associated with individual impression copings with a piston offers a simple and efficient impression procedure for small and medium implant-supported fixed partial dentures. This article presents the FM-Clip system for EVL implants composed of new straight monobloc posts and small impression copings with a piston for precise impressions and easy production of implant-supported fixed partial dentures.Abstract
New generation of titanium monobloc post with a round internal-angle cervical limit (FM-Clip system). This shape allows it to clip individual impression copings.Figure 2. Individual impression coping FM-Clip with removable piston and side spouts for the evacuation of the excess impression material.Figure 3. The FM-Clip set: a titanium monobloc post, an individual impression coping FM-Clip in 2 parts (a perforated coping sleeve and a piston), and a protection cap.
Coping sleeves filled with light silicone, individually positioned on the new-generation posts and activated with the piston. The impression material escapes through the side spouts of the coping sleeves.Figure 5. Global overimpression taken with putty silicone on the entire dental mandibular arch.
Working cast in a high-quality epoxy resin. Notice that the direct impression from the new monobloc posts is very precise, particularly in its relation with the peri-implant tissues. It easily allows the realization of a quality interim fixed partial denture or even the definitive prosthesis directly.Figure 7.
