The silent period in the masseter and in the anterior portion of the temporal muscle during tooth tapping, the rate of tooth tapping and the jaw jerk reflex evoked by a tap on the chin were compared in individuals with oral implant bridges and with natural teeth. Thirteen women with osseointegrated oral implant bridges in one or both jaws, aged 42-59 years, were compared with 10 women, aged 42-64 years, with natural teeth. There was no difference between women, aged 42-64 years, with natural teeth. There was no difference between women with implant bridges and those with natural teeth in tooth tapping rate or in the occurrence, latency or duration of the jaw jerk reflex. A silent period during tooth tapping was found in 12 of the 13 women with implant bridges. The latency of the silent period was the same as in the subjects with natural teeth but the duration tended to be somewhat longer. The jaw jerk and the silent period were the same in individuals with implants in both jaws as in the whole implant group. It is therefore concluded that periodontal or mucous membrane receptors cannot be solely responsible for the silent period.
比较了植入口腔种植桥的个体和天然牙个体在叩齿时咬肌和颞肌前部的静息期、叩齿频率以及轻敲下巴诱发的下颌反射。将13名年龄在42 - 59岁、单颌或双颌植入骨整合口腔种植桥的女性与10名年龄在42 - 64岁、拥有天然牙的女性进行比较。42 - 64岁拥有天然牙的女性之间没有差异。植入种植桥的女性与拥有天然牙的女性在叩齿频率、下颌反射的发生、潜伏期或持续时间方面没有差异。在13名植入种植桥的女性中，有12名在叩齿时出现了静息期。静息期的潜伏期与拥有天然牙的受试者相同，但持续时间往往稍长一些。双颌植入种植体的个体的下颌反射和静息期与整个种植体组相同。因此得出结论，牙周或黏膜受体不能单独对静息期负责。
