Risk factor model of mechanical complications in implant‐supported fixed complete dentures: A prospective cohort study

Abstract: Within the limitations of this study, the results suggest that clinical success is associated to framework design with retention pins equal or longer than 4 mm. Quality of life improved with IFCD treatment, even in patients with mechanical complications.

“…A recent risk factor model of mechanical complications in implant‐supported fixed complete dentures did not register a significant association between gender and mechanical complications; whereas a recent retrospective study investigating the frequency and type of complications associated with interim, immediate loaded full‐arch prostheses per All‐on‐4 protocol did not disclose any significant association between gender and mechanical complications in interim prostheses in function for an average period of 6 months . Possible explanations for these differences may rely on the study follow‐up, with the present study comprising an evaluation with at least 10 years compared to the average of 6 months and 3 years of the previous cited investigations; or in the lack of control for other variables of interest (such as bruxism) in the present study. The type of prosthetic material used in the restoration also impacted significantly the risk of mechanical complications, with metal‐acrylic and metal‐ceramic prostheses exerting a protective effect when compared with acrylic‐resin prostheses.…”

“…These patients present, to a greater or lesser extent, gingival inflammation that may cause peri-implant bone loss [64][65][66][67][68][69][70][71][72]. This peri-implant bone loss may be directly affected by the stress generated in the implant-bone-prosthesis area; the higher the transferred force, the higher the risk of peri-implantitis [21,[73][74][75][76][77][78][79]. The amount of cortical bone could also be a factor to be considered when choosing the material for manufacturing the prosthesis, as this cortical bone is poorly vascularized, fragile, rigid, and regenerates slowly [80][81][82][83][84].…”
