| abstract |
A Head fixation apparatus includes a frame and a fixation structure for repeatably and reproducibily fixing the frame to a patient's head such that locations within the head are spatially definable with reference to frame. The fixation structure includes a cast of the patient's upper teeth and/or palate. The fixation structure further includes a support for rigidly connecting the cast to the frame and biasing structure operable between the head and the frame and/or the fixation structure to bias the cast into positive contact with the upper teeth and/or palate. The apparatus is used in stereotatic diagnosis and treatment. |
