CAMLOG Hybrid Restorations

50 HYBRID RESTORATIONS WITH THE CAMLOG ® IMPLANT SYSTEM RELINING OF A BALL ABUTMENT-RETAINED FULL DENTURE The denture-bearing area must be checked at regular intervals and if necessary adjusted by relining to ensure that the ball-retained, soft tissue- supported denture retains its long-term function. IMPRESSION TAKING The denture base is prepared in accordance with the procedures for a relin- ing impression. For easy removal of the relining impression, the lamella retention inserts must be deactivated in the matrices with the screwdriver/ activator for ball abutment matrix before taking the impression. The lamella retention insert must not be extend out of the matrix housing (see "Setting the retention force"on page 42). The relining impression is taken over the CAMLOG ® ball abutments directly without accessories. The CAMLOG ® ball abutments must be fully over- molded and integrated with impression material. Silicone or polyether are suitable impression materials. CAST FABRICATION After the impression is taken successfully, the clinician must communicate the implant diameters used for cast fabrication to the dental laboratory. Brass ball abutment analogs of the appropriate diameter are then inserted in the matrices in the impression without stabilizing rings. The guide areas of the circular plateau ensure that the implant axis is transferred precisely to the master cast. The cast is fabricated in the usual manner with suitable material.
