Survival and complication rates of tooth-implant versus freestanding implant supporting fixed partial prosthesis: a systematic review and meta-analysis

Purpose: This systematic review was performed to compare tooth, implant and prosthesis failures biological technical complications in toothimplant vs freestanding supported fixed partial prostheses, order evaluate the effectiveness predictability combining teeth implants same prosthesis. Study selection: A comprehensive literature research conducted, according PRISMA (Preferred Reporting Items for Systematic Reviews Meta-Analyses) statement, identify human trials, with a minimum sample size of 10 patients, comparing tooth-implant prostheses. Four groups meta-analyses were based on patients treated implant-supported prostheses: abutment failures, mechanical complications, prosthetic (technical) complications. Results: The search yielded 749 records, after removal duplicates. Based title assessment, abstracts reading full-texts evaluation, 8 articles, published between 1999 2013, fulfilled inclusion criteria included meta-analysis. studies were: 4 controlled clinical 2 prospective retrospective cohort studies. meta-analysis revealed no significant difference implant-implant number (implant or tooth) lost, Conclusions: Within limitations present review, although remains first choice, joining support partially edentulous becomes valid alternative an acceptable success rate.
