Title Proximal Contact Maintenance Between Implant Supported Fixed Prosthodontics And Adjacent Teeth
Clinical Question In patients with implant supported fixed prosthetics, are the proximal contacts between the prosthetic and the adjacent natural teeth maintained with time?
Clinical Bottom Line Loss of proximal contact was observed between implant supported fixed prosthetics and adjacent natural teeth. The mesial proximal contact was lost most frequently. (See Comments on the CAT below)

#1) 21209989Koori/2010114 patients selected for natural teeth adjacent fixed prosthetics, implant supported fixed partial dentures and endosseous root form implants; pts suffering from significant systemic diseases were excluded.Retrospective study
Key results51% of mesial contacts and 15% of distal contacts were lost over time. Over time, it was shown that half of all proximal contacts were lost within 5.5 years.

The Evidence
This study is the first of its kind on this topic and has not yet been corroborated by other clinicians. It is also a retrospective study which does make it less valid that is desirable.
Applicability This study is relevant to any patient with an implant supported fixed prosthetic adjacent to natural teeth.

Interesting! Observed this on several occasions. Always mesial. Had radiographic evidence of contact on several, then contact was gone.
