Work Instruction GUIDE-SYSTEM

Guide System 19 Mounting the implant analogs Before mounting, the implant analogs are attached to the corresponding insertion posts, and both the connection gap and the groove on the in- sertion post above being blocked out with wax. The implant analogs are inserted in the guiding sleeves of the template. Here, care must be taken to ensure that the orientation fits the position of the mark on the top of the guiding sleeve. The orientation of the groove is identical to the position of the surfaces on the insertion post. The mark on the top of the guiding sleeve and the surface of the insertion post must therefore meet up directly (see graphic). IMPORTANT NOTE The shoulders of the insertion posts must lie on the top of the guiding sleeves. Only then is the exact final position achieved! To ensure the correct position of the insertion posts, a sufficient quantity of wax is used to mount the insertion posts fitted in the exact position in the template. The drilling template is placed on the working model or snapped into position on the analogs of the temporary implants. The im- plant analogs may not come into contact with the walls of the drill holes in the model. The implant analogs are then mounted in the model and the material (e.g., plaster, epoxy, etc.) preferably flows from the underside of the model into the drill hole. After the material has cured, the template is removed from the model by loosening the mounted insertion posts. Any residual wax on the coronal margin of the implant analogs is removed. Fabricating the temporary restoration The long-term temporary restoration can then be fabricated on the wor- king model using, for example, bar components (Passive-Fit) or the tem- porary abutment as an esthetic, non-functional bridge restoration. To guarantee a tension-free seating, a temporary reconstruction must be bonded in the mouth to the bar bases or the temporary abutment (Pas- sive-Fit). For stability reasons, the implants should be splinted together with a temporary restoration. Temporary single tooth restorations can be fabricated on the temporary abutment in the conventional manner. Alternatively, temporary restorations can be fabricated using CAD/CAM techniques.
