Abstract:Objective To evaluate and compare the clinical effect between lingualized occlusion complete denture and anatomical bilateral balanced occlusion complete denture. Method From January 2016 to June 2017, 72 edentulous patients who were selected were randomly divided into two groups and were respectively made lingualized occlusion complete denture and anatomical bilateral balanced occlusion complete denture. Masticatory efficiency and occlusion pressure were examined at 1, 3, and 6 months. Satisfaction rate was examined by questionnaire. Results Compared with anatomical bilateral balanced occlusion complete denture, the masticatory efficiency and satisfaction rate of comfort level, stability, and masticatory function in lingualized occlusion complete denture group was higher(P<0.05). The occlusion pressure was less in the lingualized occlusion complete denture group(P<0.05). Conclusion Compared with the complete denture of anatomic bilateral balanced occlusion, the complete denture of lingualized occlusion has higher satisfaction rate in comfort level, stability, and masticatory function, with the higher masticatory efficiency and less occlusion pressure, which delays the absorption of alveolar ridge in edentulous patients with low alveolar ridge.
