The purpose of the present study was to determine the distribution and level of temperature, in a model of a maxillary canine, the surrounding periodontal tissues, and the bones, during a System B heat obturation technique simulation.
The temperature distribution was determined by using a three-dimensional finite element analysis. The tooth was assumed to have undergone an endodontic treatment before the application. Heat applications of 200 degrees C and 100 degrees C were considered.
By using the virtual model and the simulation technique, the maximum temperature in the periodontal ligament was found to be 43.5 degrees C.
Within the assumptions and the limitations of the study, it was determined that the simulation of System B technique created no potentially harmful levels of temperature throughout the maxillary canine model.
本研究的目的是在模拟System B热充填技术的过程中，确定上颌尖牙模型、周围牙周组织和骨骼中的温度分布及水平。
采用三维有限元分析确定温度分布。假设牙齿在应用该技术前已接受过根管治疗。考虑了200摄氏度和100摄氏度的热应用。
通过使用虚拟模型和模拟技术，发现牙周膜中的最高温度为43.5摄氏度。
在本研究的假设和局限性范围内，确定System B技术的模拟在整个上颌尖牙模型中未产生潜在有害的温度水平。
