The feasibility of removal of salivary calculi with the aid of high energy shock waves was investigated. The postulation was, that salivary stones can be fragmented and no harm will be done to the surrounding tissues. An in vitro experiment was done with a lithotriptor to test the effect on a salivary stone and an extracted upper molar containing an amalgam restoration. Also investigated was whether a patient can be positioned in a prone position on the lithotriptor. In the in vitro experiment, the salivary stone was fragmented very quickly, but the amalgam restoration also fragmented. The patient could be positioned in the correct position on the lithotriptor, but because of the expected damage to the dentition, the experiment was not carried out on the patient.
研究了借助高能冲击波清除唾液腺结石的可行性。推测是唾液腺结石可被击碎且不会对周围组织造成损害。用碎石机进行了一项体外实验，以测试对唾液腺结石和一颗含有汞合金修复体的拔除上颌磨牙的影响。还研究了患者能否俯卧在碎石机上。在体外实验中，唾液腺结石很快就被击碎了，但汞合金修复体也被击碎了。患者可以在碎石机上处于正确位置，但由于预计会对牙列造成损害，所以未对患者进行该实验。
