口腔中的臼齒具有複雜之幾何外形,由其咬合面上呈現高低不平的形態,這種特性有助於其在咀嚼過程中有效研磨及壓碎食物,但在終年累月長時間咀嚼狀態下,磨耗現象將應運而生。本研究嘗試設計一組可模擬口腔咀嚼行為之簡易型模擬器,該模擬器在與動態材料試驗機結合後,透過試驗機上所具備的各種控制功能,進一步仿真模擬出口腔內牙齒之上╱下運動以及研磨、撕裂及攪拌食物之橫向動作。
本研究將利用該模擬器對不同之復形材及臼齒琺瑯層切片進行後續一系列之磨耗試驗。實驗結果顯示,在同種材料與異種材料互磨情況下,三種實驗復形材當中以軟質基地填加奈米鋇玻璃粒子之CharmFil Plus-A3具最佳之抗磨耗性。在動態負載磨耗試驗當中,此時上/下試片在正常磨損磨耗機構外會因受到反覆應力作用而伴隨產生疲勞磨耗,因此其磨耗損失會較相同條件之負載情況高出甚多。針對口腔環境效應的影響,由於人工唾液具備較高之潤滑性,因此其磨耗損失會低於另一以去離子水為磨耗環境之試片。兩種環境在各加入不同比例之石灰後,此時硬質石灰顆粒在磨耗過程中相當於是研磨切削粒子,它含量的多寡左右了復形材之磨耗損失嚴重程度。
The molars inside oral cavity reveal a complicate morphology on their occlusal planes. Such a characteristic is helpful for grinding and avulsing foods. Owing to a long-time routine use, the wear of molars will become an important problem inside oral cavity. In this investigation, a simple oral wear simulator including two divided units has been designed. This simulator was constructed with a dynamic material testing machine (Instron 8801). By using the multiple control and real time monitoring functions of above facility, the oral motion behavior can be simulated while the wear research of molars and restorative materials are proceeding.
Three types of restorative materials and the enamel of molars were used as the wear samples in the simulator. The experimental results indicate the CharmFil Plus-A3 with soft matrix and strengthening Barium glass particles in nano-scale reveals a good wear resistance in both the wearing situation of similar and dissimilar material combinations. In case of dynamic loading, the wear loss of samples is larger than that in the static loading under the same degree of loading condition. This was due to the extra mechanism of fatigue wear occurs in the dynamic loading situation. In case of the comparison of environmental effect on the wear, the wear loss of sample in artificial saliva has been demonstrated smaller than that in the distilled water owing to a batter lubrication of the artificial saliva. By adding lime particles into above two lubricants, the wear loss of samples increases rapidly by increasing the adding concentration of lime particles.
