Masticatory forces associated with porcelain and acrylic resin occlusal surfaces on osseointegrated implant-supported prostheses opposing natural teeth were studied in five healthy subjects. A three-channel electronic force transducer carrying a fixed prosthesis with either acrylic resin or porcelain occlusal surfaces and balanced articulation was used to record masticatory forces while the subjects chewed various foods. It was found that mean peak masticatory forces varied considerably from subject to subject but were consistent within each subject. No differences related to tooth material could be detected in the load rates. Forces directed away from the implants were noted in all subjects.
在五名健康受试者中,研究了与种植体支持的固定修复体上的瓷和丙烯酸树脂咬合面相对的天然牙相关的咀嚼力。使用带有丙烯酸树脂或瓷咬合面的固定修复体以及平衡咬合的三通道电子力传感器,在受试者咀嚼各种食物时记录咀嚼力。结果发现,平均峰值咀嚼力在受试者之间差异很大,但在每个受试者内部是一致的。在加载速率方面未检测到与牙齿材料相关的差异。在所有受试者中均观察到远离种植体的力。
