摘要:
The invention relates to a system and method for determining the occlusal surface of a patients jaw. The system comprises a contact-detecting member designed to be inserted between the patients teeth and means for calculating the distribution of occlusal forces in order to produce a map. The detector member comprises a removable flexible plate formed by a sheet of flexible plastic material solidly connected to a grid of pressure sensors comprising a first layer including three layers, two electrode layers sandwiching an intermediate layer having a resistivity that varies according to the pressure applied thereto. The electrodes define so-called intersection zones forming at least 5000 sensors having a square cross-section of less than or equal to 600 micrometres. The intermediate layer comprises a microcrystalline silicon semiconductor wafer having a thickness less than or equal to 50 nanometres.
