How can we make intra-oral cementation safer? Residual excess cement is a known risk factor for peri-implant disease, and know that it is an all-to-common consequence of current installation techniques. This presentation will discuss how adjacent gingiva, abutment, and prosthesis deign affect the flow of excess cement as it is ejected from between the margins of the abutment and prosthesis during installation. There also will be a discussion of how to control the flow of excess cement and thus prevent the problem of residual excess cement; this alone promises to reduce iatrogenic complications by 60%, as extrapolated from the work of Wilson 2008.

It is not only the excess cement that can be a problem. There are a number of reports about techniques that attempt to minimize the cement volume ejected beyond the margins of the prosthesis. These techniques, unfortunately, do not consider the danger of creating cement voids under the prosthesis that can breed oral pathogens thus creating peri-implant disease. Discussion will include a new cement application technique that minimizes the formation of cement voids and therefore makes intra-oral cementation even safer.

Learning Objectives: Upon completion of this course, participants should be able to:

1. Identify the iatrogenic contribution to the incidence of peri-implant disease and its resulting treatment complications

2. Understand why intra-oral cementation still is a necessary part a safer of prosthesis installation protocol
