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.
对15例无牙颌患者的无症状阻生牙进行了长期评估。记录并分析了15例患者的17颗阻生牙。它们位于义齿承托区和正接受修复前手术的区域。除1例在1年随访期后失访外，所有患者均接受了1至10年的临床和影像学随访，平均随访4年。无牙颌中埋于骨内或被黏膜覆盖的无症状阻生牙未给患者带来任何问题。本研究结果支持以下观点：只要覆盖组织完整，就无需拔除义齿承托区或正接受修复前手术区域的无症状阻生牙。建议采取影像学监测策略。
