Prospective clinical evaluation of mandibular implant overdentures: Part II--Patient satisfaction and preference

J Prosthet Dent. 1995 Apr;73(4):364-9. doi: 10.1016/s0022-3913(05)80332-4.


In a crossover experimental design, a prospective clinical study was performed with 17 subjects with existing complete dentures. After data collection, two implants were placed bilaterally in the anterior mandible. Conventional dentures were modified into implant overdentures by use of O-ring and magnet attachments. Each attachment was maintained with each subject for 6 months. Subjects responded to patient satisfaction and preference questionnaires about the conventional denture and each attachment. Subjects were satisfied with both attachment overdentures but showed a strong preference for the O-ring. Both attachments resulted in a significant increase in patient satisfaction when compared with the conventional denture.
