The aim of this study is to evaluate the maximum bite force (MBF) with different denture base materials in completely edentulous patients.
MBF was evaluated in randomly selected 100 completely edentulous patients. Patients were selected from the Outpatient Clinic, College of Dentistry, Aljouf University, Saudi Arabia. The patients were randomly divided into two equal groups: Group I (control group): Patient received a conventional heat-cured acrylic complete denture (Vertex™ Regular, Vertex-Dental B.V., The Netherlands) and Group II (experimental group): Patient received a thermoplastic complete denture (Vertex™ ThermoSens, Vertex-Dental B.V., The Netherlands). MBF measurements were taken at the time of new denture placement and after 6 months of denture use. Statistics were analyzed using independent -test to compare the MBF measurements between both groups.
At the time of denture placement, there was no significant difference in bite force measurements between both groups. Bite force is increasing considerably after 6 months of denture use, and it was higher than MBF recorded at the time of new prosthesis placement in the same group. The MBF values were considerably higher in patients with a thermoplastic denture than patients with conventional acrylic denture with statistically significant difference after 6 months of denture use.
After 6 months of denture use, patients with a thermoplastic denture have a higher biting force than patients with a conventional acrylic denture. Therefore, it could be considered a treatment plan option according to the ridge nature and quality to solve the problem of diminished bite force in old age patients.
本研究旨在评估全口无牙患者使用不同义齿基托材料时的最大咬合力(MBF)。
随机选取100例全口无牙患者评估其最大咬合力。患者选自沙特阿拉伯阿尔朱夫大学牙科学院门诊。将患者随机分为两组,每组人数相等:第一组(对照组):患者佩戴传统热凝丙烯酸全口义齿(Vertex™ Regular,荷兰Vertex-Dental B.V.公司);第二组(试验组):患者佩戴热塑性全口义齿(Vertex™ ThermoSens,荷兰Vertex-Dental B.V.公司)。在新义齿佩戴时及佩戴6个月后测量最大咬合力。采用独立样本t检验分析统计数据,以比较两组之间的最大咬合力测量值。
义齿佩戴时,两组的咬合力测量值无显著差异。义齿使用6个月后咬合力显著增加,且高于同一组新义齿佩戴时记录的最大咬合力。使用义齿6个月后,佩戴热塑性义齿患者的最大咬合力值显著高于佩戴传统丙烯酸义齿的患者。
义齿使用6个月后,佩戴热塑性义齿的患者比佩戴传统丙烯酸义齿的患者咬合力更高。因此,根据牙槽嵴的性质和质量,可将其视为一种治疗方案选择,以解决老年患者咬合力下降的问题。
