Abstract:

Background and aim: The aim of current systematic review and meta-analysis study was evaluate Dental Implant Survival in Patients Undergoing Vascularized Maxillary or Mandibular Reconstruction. Methods: From the electronic databases, PubMed, Scopus, LILACS, Web of Science, EBSCO, LIVIVO, and Embase have been used to perform a systematic literature over the last five years between 2016 and September 2021. Effect size and Risk ratio with 95% confidence interval (CI), fixed effect model and Inverse-variance or Mantel-Haenszel method were calculated. The Meta analysis have been evaluated with the statistical software Stata/MP v.16 (The fastest version of Stata). Results: 1452 studies were selected to review the abstracts, the full text of 39 studies was reviewed. Finally, eight studies were selected. Implant Survival in 294 patients who underwent Dental Rehabilitation with 1138 total implants (Microvascular Flaps) was 94% (ES, 0.94 95 % CI 0.60, 1.29) and in the Preirradiation Implant Placement in 9 patients with 59 implants was 93% (ES, 0.93 95 % CI 0.36, 1.50). Statistically significant difference of survival outcomes between radiotherapy and no radiotherapy group observed (p=0.00); radiotherapy significantly increased the risk of implant failure. Conclusions: in patients Undergoing Vascularized Maxillary or Mandibular Reconstruction, Osseointegrated dental implant placement is successful technique and improve their quality of life and oral function, and should be given special attention in these patients.
