Periodontal prosthesis: control of key factors from surgery to teeth preparation and to final cementation.

Prosthetic periodontal treatment with a fixed partial prosthesis has been carried tients affected by severe periodontitis in order to restore dentition to good health, function, and esthetics. The literature has proven that the biological capability of teeth with a reduced but healthy periodontium successfully supports a fixed partial prosthesis over time. In gren demonstrated that fixed bridges can be placed and successfully maintained on a minimal number of abutment teeth with significantly reduced peri-
