Clinical comparison of magnetic attachment and ball⁃cap attachment in the complete denture restoration on mandibular edentulous jaw

Abstract

Objective To compare the clinical effect of magnetic attachment and ball⁃cap attachment in implant re⁃ habilitation 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 re⁃ ceived 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 satisfac⁃ tion 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 bet⁃ ter 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 (c2 = 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 peri⁃ odontal tissue, which make patients feel more comfortable and satisfied.
