Zusammenfassung

Objective To compare the clinical effect of magnetic attachment and ball-cap attachment in implant rehabilitation in mandibular edentulous patients. Methods 128 mandibular edentulous were divided into A, B two groups according to double-blind randomization. There were 64 people in each group. Subjects in group A and B received routine oral examination, panoramic radiograph to establish the model of alveolar bone and make restoration plan. The magnetic attachment was applied in patients of group A in restoration treatment, while ball-cap attachment was used in group B. Patients of both groups were recalled a year later, and the periodontal tissue health and satisfaction were evaluated. The periodontal tissue health was examined according to clinical standards. Results The gingival health status of group A and B showed significant differences (P = 0.00), The gingival health status of group A was better than group B. The mobility was also analyzed. The results showed that group A was better than group B in mobility of abutments (P = 0.003), There was no significant difference (χ2 = 1.875, P > 0.05) in aesthetics. There was significant difference (P < 0.05) between two groups in fixity, chewing ability and comfortability. Group A were better than group B. Conclusion The magnetic attachment shows better performance in implant retention and protects the health of periodontal tissue, which make patients feel more comfortable and satisfied.
