DEVICE FOR MEASURING THICKNESS OF MAXILLARY SINUS BONE AND LENGTH OF ROOT CANAL AND METHOD USING THE SAME

摘要

PURPOSE: A device for measuring maxillary sinus bone thickness and length of root canal and measurement method using the same are provided, which can accurately measure thickness of the maxillary sinus bone and prevent damage of maxillary sinus membrane. CONSTITUTION: A device for measuring maxillary sinus bone thickness and length of root canal comprises an insert terminal(30) which is inserted into the alveolar bone; a fixed terminal(60) which is electrically connected to a part of the human body; and a controller unit(80) which is connected to the insert terminal and fixed terminal and judges whether electricity is put through or not between the insert terminal and fixed terminal.
