Purpose of the review. To evaluate the survival and clinical efficacy of subperiosteal dental implants versus endoosal implants in severe jaw atrophy. Only clinical trials (randomized, cohort, prospective) for 2010-2025 are included in the review. Methods. The databases (PubMed, Scopus, etc.) were searched according to PRISMA; selected studies reporting implant survival rates, duration of follow-up, and incidence of complications. 10 studies with a total of ~ 300 patients were analyzed. Results. Modern individually manufactured subperiosal dental implants show a high short-term survival rate of about 95-97% for 1-5 years, which is similar to that of endoosal implants in patients with bone atrophy (for example, 96-98% survival). Long-term survival of subperiosal implants is somewhat lower: in some series – ~ 80-85% at the 10-year milestone, while for standard endoosal implants this figure reaches ~ 90-95%. The frequency of complications in subperiosteal implants is higher on the side of soft tissues: partial exposure of the metal frame was observed in ~ 20-25% of cases, infectious complications in ~ 5%. Instead, for endoosal implants with severe atrophy, typical sinus complications (rhinosinusitis) ~ 10-15% and the risk of perforation. Conclusions. Modern subperiosteal implants (CAD/CAM and 3D printed) are a viable alternative to traditional endoosal implants in patients with severe bone atrophy. Short-term survival of subperiosteal implants is not inferior to endoosal ones, but there is a higher incidence of soft tissue complications. Further prospective studies with a longer follow-up period are needed to confirm the long-term efficacy of subperiosteal implants.
