Abstract
Aim: To evaluate and compare the maximum bite force (MBF) among completely edentulous patients with different facial types and to assess its variation according to gender.
Materials and methods: A total of 120 completely edentulous subjects (60 males and 60 females) aged 50-60 years were classified into euryprosopic, mesoprosopic, and leptoprosopic facial types based on facial index measurements. Maximum bite force was recorded bilaterally in the premolar-molar region using a custom-made strain gauge transducer, and the mean value was calculated for each subject. Data were analyzed using one-way ANOVA and independent t-tests, with statistical significance set at p < 0.05.
Results: The mean (±SD) MBF values for Euryprosopic, Mesoprosopic, and Leptoprosopic facial types were 6.327 ± 1.505 kg f, 4.406 ± 0.709 kg f, and 3.070 ± 1.263 kg f, respectively, with a statistically significant difference among groups (p < 0.001). Males demonstrated significantly higher MBF (5.615 ± 1.627 kg f) compared to females (3.586 ± 1.334 kg f) (p < 0.001). Euryprosopic individuals exhibited the highest bite force, followed by mesoprosopic and leptoprosopic subjects.
Conclusion: Maximum bite force in completely edentulous individuals varies significantly with facial morphology and gender. Higher bite forces were observed in Euryprosopic individuals and males, suggesting superior masticatory efficiency.
Clinical significance: Assessment of facial morphology and bite force before prosthetic rehabilitation may aid in optimizing denture design, improving occlusal balance, and enhancing masticatory performance and patient satisfaction.
目的：评价和比较不同面部类型的全无牙患者的最大咬合力（MBF），并评价其在性别上的差异。材料与方法：选取年龄50 ~ 60岁的120例完全无牙者（男60例，女60例），根据面部指数分为全颌、中颌和细颌三种类型。使用定制的应变计传感器记录双侧前磨牙区域的最大咬合力，并计算每个受试者的平均值。资料分析采用单因素方差分析和独立t检验，p < 0.05为差异有统计学意义。结果：全斜面型、中斜面型、细斜面型的平均MBF值（±SD）分别为6.327±1.505 kg f、4.406±0.709 kg f、3.070±1.263 kg f，组间差异有统计学意义（p < 0.001）。男性MBF（5.615±1.627 kg f）明显高于女性（3.586±1.334 kg f） （p < 0.001）。全眼个体的咬合力最高，中眼和细眼次之。结论：全无牙个体的最大咬合力因面部形态和性别的不同而有显著差异。在Euryprosopic个体和雄性中观察到更高的咬合力，表明优越的咀嚼效率。临床意义：义齿康复前评估面部形态和咬合力有助于优化义齿设计，改善咬合平衡，提高咀嚼功能和患者满意度。
期刊介绍：
The Journal of Contemporary Dental Practice (JCDP), is a peer-reviewed, open access MEDLINE indexed journal. The journal’s full text is available online at http://www.thejcdp.com. The journal allows free access (open access) to its contents. Articles with clinical relevance will be given preference for publication. The Journal publishes original research papers, review articles, rare and novel case reports, and clinical techniques. Manuscripts are invited from all specialties of dentistry i.e., conservative dentistry and endodontics, dentofacial orthopedics and orthodontics, oral medicine and radiology, oral pathology, oral surgery, orodental diseases, pediatric dentistry, implantology, periodontics, clinical aspects of public health dentistry, and prosthodontics.
