24 I I industry report _ CAMLOG Guide System fixation for the preparation of radiological ma- terials. The fixation is facilitated by temporary implants in a suitable position. Inordertoensureaccuratetransferability,the fixation must be performed under radiological control in the identical position as the one for the implantation. The scan template is fabricated based on prosthetic requirements (functional, aesthetic). A bone-anchored and prosthetic-oriented scan can be taken under radiological control owing to the unique fixation of the scan template using the interim implants. The thickness of the mucous membrane can be measured by fitting the radio-opaque tooth along the plaster surface. The distance from holding sleeve to bone surface must not exceed 3.5 mm.
