Abstract
BACKGROUND:Precision attachment has been used in complete denture in mandibular edentulous patients because of its strong retention, higher masticatory efficiency, and prevention of alveolar bone resorption. Among them, magnetic attachment and bal-cap attachment are commonly applied for mandibular complete denture. OBJECTIVE:To compare the clinical treatment effects of magnetic attachment and bal-cap attachment-retained complete denture used in mandibular edentulous patients. METHODS:This study included 50 patients with dentition defects, 28 males and 22 females, aged from 40 to 82. And they were randomly divided into two groups (n=25 in each) and treated with magnetic attachment and bal-cap attachment retention of mandibular removable partial denture. Masticatory function was tested after 6 months of wearing denture, and the satisfaction of patients and the periodontal health of abutments were surveyed after 2 years of wearing denture. RESULTS AND CONCLUSION: After 6 months of wearing denture, two groups had both higher masticatory efficiency, but no significant differences between two groups were found. After 2 years of wearing denture, the retention conditions and comfortable satisfaction of the magnetic attachment group was significantly higher than that of the bal-cap attachment group (P < 0.05). The gingival index, sulcus bleeding index and abutment mobility in the magnetic attachment group were significantly lower than those in the bal-cap attachment group (P < 0.05). And the alveolar bone height of the magnetic attachment group was significantly higher than that of the bal-cap attachment group (P < 0.05). Experimental results indicate that the mandibular restoration complete denture with magnetic attachment shows superiority in retention than with bal-cap attachment. The magnetic attachment provides better retention and better protection for periodontal tissue compared with the bal-cap attachment.关键词
