To investigate the effect of varying interdental bite platform thickness of the scuba mouthpiece on airway efficiency.
10 male divers had their mean peak flow measured for free breathing, maximum flow with diving mouthpiece, teeth in occlusion, and for five experimental mouthpieces with different thickness of interdental bite platform (1 mm, 2 mm, 3 mm, 4 mm, and 5 mm).
The connecting airway between the demand valve and mouthpiece was found to be a major limiting factor in airway efficiency. An interdental bite platform of 4 mm resulted in the greatest air flow with a further increase in thickness resulting in air flow restriction.
The use of an interdental bite platform of 4 mm placed between the premolar and molar teeth ensures the greatest airway efficiency and also results in a design which provides the least temporomandibular joint discomfort for the diver.
研究水肺咬嘴不同牙间咬台厚度对气道效率的影响。
10名男性潜水员分别测量其自由呼吸时的平均峰值流量、佩戴潜水咬嘴且牙齿咬合时的最大流量，以及使用五种不同牙间咬台厚度（1毫米、2毫米、3毫米、4毫米和5毫米）的实验咬嘴时的最大流量。
发现需求阀与咬嘴之间的连接气道是气道效率的主要限制因素。4毫米的牙间咬台可产生最大气流，厚度进一步增加则会导致气流受限。
在前磨牙和磨牙之间使用4毫米的牙间咬台可确保最大气道效率，并且还能设计出为潜水员带来最小颞下颌关节不适的咬嘴。
