Objective To investigate the clinical effect of prosthesis combined with bolt-shaped attachment on unilateral maxillary defect. Methods Four patients with unilateral maxillary defect and two months after operation were treated with bolt-type attachment and hollow titanium cast prosthesis restoration to repair jaw defects and dentition defects. The voice clarity test and self-assessment And other indicators to evaluate the clinical effect. Results After the four patients were repaired, the speech intelligibility was significantly improved. The stability of the prosthesis was good, and it was comfortable to wear. The self-assessment of the patients was excellent. Conclusions The bolt-shaped attachment and the hollow titanium cast stent-shaped prosthesis repair technique can effectively repair the voice, appearance and occlusion of unilateral maxillary defect patients. The clinical effect is satisfactory.
