Maximal bite force was measured and intraoral condition was examined in 89 patients at the Institute of Dentistry, University of Turku. These patients formed three different denture groups: those with complete dentures, those with full maxillary denture and partial mandibular denture, and those with natural dentition or skeleton-supported partial maxillary denture and partial mandibular denture. There were three age groups: greater than or equal to 70, 60-69, and less than or equal to 59 years old. Maximal bite force was recorded with an appliance at seven different measuring points by placing a biting fork between the antagonistic teeth while at the same time the occlusion was stabilized contralaterally with a plastic tube. Maximal bite force had a correlation with age and sex (P less than 0.01). In partial-denture groups high bite force had a correlation with the breaking of dentures (P less than 0.001 and P less than 0.05, respectively). Satisfied patients had a higher bite force than dissatisfied ones. When there was some disturbance in occlusion, the bite force was smaller, especially in full-denture groups (P less than 0.001). Full-denture wearers also had a good bite force, but the best biting area was located more posteriorly than in patients who still had some natural teeth left in both jaws. Changes in the denture-bearing mucosa in patients with complete dentures and negative height of the mandibular alveolar process decreased the bite force slightly.
在图尔库大学牙科学院对89名患者测量了最大咬合力，并检查了口腔状况。这些患者分为三个不同的义齿组：全口义齿患者、上颌全口义齿和下颌部分义齿患者，以及天然牙列或骨架支撑的上颌部分义齿和下颌部分义齿患者。有三个年龄组：70岁及以上、60 - 69岁和59岁及以下。通过将咬叉置于对颌牙之间，同时用塑料管在对侧稳定咬合，使用一种器械在七个不同测量点记录最大咬合力。最大咬合力与年龄和性别相关（P < 0.01）。在部分义齿组中，高咬合力与义齿折断相关（分别为P < 0.001和P < 0.05）。满意的患者比不满意的患者咬合力更高。当咬合出现某些紊乱时，咬合力较小，尤其是在全口义齿组（P < 0.001）。全口义齿佩戴者也有较好的咬合力，但最佳咬合区域比上下颌仍保留一些天然牙的患者更靠后。全口义齿患者义齿承托黏膜的变化以及下颌牙槽突高度负值会使咬合力略有下降。
