CAMLOG Hybrid Restorations

51 HYBRID RESTORATIONS WITH THE CAMLOG ® IMPLANT SYSTEM RELINING NOTE Before relining, the inner configuration of the matrices must be insu- lated with Vaseline to prevent acrylic from getting into the matrices. This would destroy the matrices. The prosthesis is relined in the usual dental manner. After relining, the pros- thesis is trimmed and the inner configuration of the matrices cleaned. The clinician then activates the lamella retention inserts with the screw- driver/activator for ball abutment matrix (see "Setting the retention force" on page 42), the occlusion checked and the finished prosthesis inserted in its final position. FOLLOW-UP/RECALL Ball abutment-retained prostheses should be checked for functional reli- ability initially at intervals of about three months. In doing so, harmful pros- thetic movements can be detected early and eliminated by appropriate measures (replacement/activation/deactivation of matrices, relining, occlu- sion check). The prosthesis is cleaned and the patient instructed again under conditions of poor hygiene. NOTE Only clean the components of the ball abutments with suitable instru- ments. Metal instruments can damage them. REPLACING THE LAMELLA RETENTION INSERT The retention force of the lamella retention insert may be reduced by stress or wear. To replace it, use the screwdriver/activator for ball abutment matrix to unscrew it counter-clockwise from the matrix housing (see "Setting the retention force" on page 42). The new lamella retention insert is screwed in clockwise into the matrix housing. Make sure that it is placed axially. For a controlled adjustment of the retention force, the lamella retention insert is first screwed in completely and then unscrewed one complete turn. This sets the retention force to about 200 g (basic setting). The total retention force can be individually adjusted at the time of insertion of the denture.
