CAMLOG Hybrid Restorations

47 HYBRID RESTORATIONS WITH THE CAMLOG ® IMPLANT SYSTEM BROADENING OF AN EXISTING FULL DENTURE INTO A BALL ABUTMENT-RETAINED FULL DENTURE An existing mucosa-supported full denture can be converted into a ball abutment-retained prosthesis in principle, but this will weaken the prosthe- sis. Because it is known that the chewing force increases with implant- retained dentures, the denture can fracture without metal reinforcement. This procedure can only be considered as a temporary solution. SELECTION AND INSERTION OF THE CAMLOG ® BALL ABUTMENTS After the CAMLOG ® implants have healed, the CAMLOG ® ball abutments are inserted. In conformance with the specified implant diameters and gin- gival heights, the clinician selects the CAMLOG ® ball abutments intra- orally and uses the driver for ball abutment to screw them into the previ- ously cleaned CAMLOG ® implants. Information about torques, see page 46. Different abutment heights can be selected to compensate for differences in levels in the gingival margin and implants. The ball heads should be at a uniform level for the best possible retention effect. The ball abutment pla- teau should be approx. 1 mm supragingival. IMPRESSION TAKING OF THE CAMLOG ® BALL ABUTMENTS The impression is taken over the CAMLOG ® ball abutments directly without accessories. The CAMLOG ® ball abutments must be fully overmolded and integrated with impression material. Silicone or polyether are suitable im- pression materials. 1mm
