Description
Pawaris Ngamdumrongkiat and Ramon Urapepon report a 2026 multicentre retrospective pilot study on whether bone loss around dental implants signals risk of prosthetic screw loosening in full-arch fixed dentures. Screw loosening is among the most common mechanical problems in these full-jaw restorations, which rest on four or six implants.
The team analysed 43 arches from 32 patients at three private clinics in Bangkok, Thailand, treated between 2017 and 2025. Screw loosening occurred in ten arches, or 23.3 percent. The number of implants showing surrounding bone loss was linked to loosening, and arches with three or more affected implants loosened sooner, at 19.5 months versus 30.0. The authors call the findings exploratory.
