  • Title: [Study on retention and stability of linear occlusal complete dentures].
    Author: Zhang P, Xu J.
    Journal: Zhonghua Kou Qiang Yi Xue Za Zhi; 2003 Jan; 38(1):46-8. PubMed ID: 12760777.
    Abstract:
    OBJECTIVE: To learn retention and stability of linear occlusal complete dentures by investigating the subjective feelings of patient and the value of retention force. METHODS: Static retention forces of maxillary and mandibular dentures were measured for 25 patients wearing linear occlusal dentures by using Hz-1 retention dynamometer. The subjective feelings of patients in functional state were gained simultaneously through questionnaire. RESULTS: Linear occlusal dentures demonstrate good retention in static and dynamic state. Among patients with severe resorption of residual ridge (RRR), mandibular linear occlusal dentures (shown good retentive subjective feelings) demonstrate significantly smaller retention force than those with slight or medium degree of RRR. There is no correlation between the subjective feelings and the values of retention forces of mandibular dentures. The subjective feelings of patients wearing new linear occlusal dentures are much better than that of old anatomic occlusal dentures. CONCLUSION: Linear occlusal dentures improve the performances of dentures by enhancing their stability during mastication movement.
