Asymptomatic impacted teeth in edentulous jaws undergoing preprosthetic surgery. A long-term evaluation.

A long-term evaluation is made of 15 patients with asymptomatic impacted teeth in edentulous jaws. Seventeen impacted teeth in 15 patients were recorded and analysed. They were located in denture-bearing areas and in areas undergoing preprosthetic surgery. All patients, except one lost after 1-year period, were followed clinically and radiographically for 1 to 10 years with an average of 4 years. The asymptomatic impacted teeth in edentulous jaws embedded in bone or covered with mucosa did not cause any problem to the patients. The findings of this study support the view that removal of asymptomatic impacted teeth in denture-bearing areas, or in areas undergoing preprosthetic surgery, is unnecessary as long as the integrity of the covering tissues is preserved. A policy or radiological surveillance is recommended.
