Prevalence of peri-implant diseases in fully edentulous patients restored with four implants supported fixed full arch prosthesis: a literature review

Restoring fully edentulous jaws with implant supported fixed prosthesis allows the restoration of function (phonetics and mastication), esthetics, and patients’ quality of life. This type of treatment is well validated by substantial body of scientific and clinical evidence (1-5). Implant 5–10-year survival rates supporting full-arch prosthesis can be as high as 98% (6,7). However, the focus of the older articles was implant osseointegration and overall survival, leaving some of the biologic complications unreported. Implant success has been re-defined, and newer evaluation parameters, such as soft tissue health, have been identified (8). Recent systematic review reported prevalence of peri-implant diseases of approximately 29% (9). This clearly highlights the importance of understanding peri-implant diseases, their cause, prevalence, and relationship between different types of prostheses. Peri-implant diseases have been classified into two major Review Article
