To compare patient perception of custom made mouthguards of ideal and less than ideal designs in terms of their comfort and "wearability".
A mouthguard of ideal design (A) and one incorporating common design faults of underextension and unadjusted occlusion (B) were provided for 22 active sportsmen and women. They were not informed of the details of the design or the status of the protector. Half the participants were asked to wear mouthguard A first and the other half wore B first, each worn for one hour on two consecutive nights. Questionnaires were used to evaluate and rate the comfort and wearability of each mouthguard.
Eighteen people completed the study. The ideal appliance was rated as significantly more retentive and comfortable overall and specifically was more comfortable to lips, gums, and tongue. It was also recognised as being less bulky, less likely to keep the teeth apart, or to cause pain in the jaw muscles.
Comfort is likely to be increased if mouthguards are extended labially to within 2 mm of the vestibular reflection, adjusted to allow even occlusal contact, rounded at the buccal peripheries, and tapered at the palatal edges.
比较患者对理想设计和不太理想设计的定制护齿器在舒适度和“可佩戴性”方面的感受。
为22名现役男女运动员提供了一个理想设计的护齿器（A）和一个存在延伸不足和咬合未调整等常见设计缺陷的护齿器（B）。他们未被告知设计细节或保护器的情况。一半参与者先佩戴护齿器A，另一半先佩戴B，每人连续两晚各佩戴一小时。使用问卷评估并对每个护齿器的舒适度和可佩戴性进行评分。
18人完成了研究。理想的护齿器在总体上被评为固位性和舒适度明显更高，具体而言，对嘴唇、牙龈和舌头更舒适。它也被认为体积更小，不太可能使牙齿分开或导致颌肌疼痛。
如果护齿器唇向延伸至前庭反射内2毫米处，调整以允许均匀的咬合接触，颊侧边缘呈圆形，腭侧边缘呈锥形，则舒适度可能会提高。
