What are the risks of a partial implant-supported bridge?

Peri-implantitis (inflammation around implants) occurs where hygiene is poor (5-15% within 10 years). Screw fractures (2-4%) result from overloading or incorrect torque settings. Ceramic fractures occur with trauma or grinding (3-7% depending on the material). Bone loss around implants leads to mobility if not monitored adequately. Allergic reactions to titanium are rare (<0.5%) but possible. An incorrect bite causes muscle pain and joint problems if not corrected. Smoking triples the risk of failure because of reduced blood supply. Annual CBCT scans detect asymptomatic bone changes early. Prevention through strict aftercare considerably minimises complications.
