Abstract

Purpose: To evaluate the effect of the location of implants, radiation therapy, and soft tissue reactions on survival rates of dental implants in the extraoral maxillofacial prosthesis. Materials and methods: An electronic search was conducted for articles published in English, listed with Medline (PubMed) and Embase from 2000 to till date. The focused question was “Is there any effect of location, radiation, and soft tissue reactions on survival rates of dental implants in extraoral maxillofacial prosthesis?” The selection of articles was done according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 guidelines. The risk of bias was checked using the Newcastle–Ottawa scale. Results: The investigation identified a total of 10,800 titles of studies with extraoral maxillofacial prostheses, out of which 17 studies were included in this review based on the selection criteria. It was seen that there was an increase in the failure rate of dental implants in the extraoral maxillofacial prosthesis in presence of radiation. The mean survival rate of implants in nonirradiated areas was 82.6% whereas that of irradiated areas was 77.72%, suggesting a lower survival rate in irradiated areas. Conclusion: Radiation therapy does affect the survival rates of implants, but they are not a contraindication. Implant placement in such cases must be calculated and planned carefully, with special emphasis on the quality of bone, location of implants and their characteristics, compliance, and manual abilities of the patients, and their health status.
