ABSTRACT
<p><b>OBJECTIVE</b>To evaluate treatment outcomes of mandibular complete denture supported by two endosteal magnetic-attachment implants in edentulous patients with severe mandibular alveolar ridge absorption.</p><p><b>METHODS</b>Eight edentulous patients with severe mandibular alveolar ridge absorption were chosen. Each of them was treated with a complete denture supported by two CDIC implants. The implants were inserted at the areas of two the first premolars respectively. After five months, two magnets were adhered to the inside of the complete dentures. Retention, masticatory efficiency and maximal masticatory force were measured before and after the magnets were adhered and six months later.</p><p><b>RESULTS</b>Statistical analysis revealed that retention, masticatory efficiency and maximal masticatory force were all increased after the magnets were adhered (P < 0.01) and six months later (P < 0.01).</p><p><b>CONCLUSION</b>Retention, maximal masticatory force and masticatory efficiency were significantly increased after the endosteal magnetic attachment implants were applied. It is concluded that mandibular complete denture supported by two endosteal magnetic attachment implants is an effective method for severe alveolar ridge absorption cases.</p>
