CAMLOG Hybrid Restorations

70 HYBRID RESTORATIONS WITH THE CAMLOG ® IMPLANT SYSTEM WAX-UP OF THE PRIMARY COMPONENTS The primary crowns are waxed up with the CAMLOG ® gold-plastic abut- ment similar to the conventional double crown technique. The minimum wax thickness over the base part must be 0.7 mm to achieve an optimal dis- charge behavior of the cast-on alloy. After wax-up, a suitable agent must be used to clean the fine gold margin and the area of the implant shoulder support of separating medium and wax particles (e.g. with a cotton swab soaked in alcohol). EMBEDDING AND CASTING The abutment is embedded according to the instruction manual of the muf- fle system used. We do not recommend the use of a wax wetting agents. The fine film from the agent can lead to a surplus of cast-on alloy on the margin or on the implant shoulder support. When embedding, the correct placement of the wax-up in the casting muffle is of importance. Volume ra- tios and pin angles must be selected so that the required temperature for formation of a metallic connection is achieved. This is particularly impor- tant for voluminous casts. CAUTION Do not cover the fine gold margin (0.3 mm) with wax. This can lead to a surplus of cast-on alloy on the margin or on the implant shoulder support. 0.3 mm gold margin Implant shoulder support DOUBLE CROWN RESTORATIONS
