CAMLOG Hybrid Restorations

29 HYBRID RESTORATIONS WITH THE CAMLOG ® IMPLANT SYSTEM INVESTMENT, CAST AND DEVESTMENT 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 agent. However, if wax wetting agents are used, it must be suitable for use with POM plastic components. When embedding, the correct placement of the wax-up in the casting muffle is of importance. Volume ratios and pin an- gles must be selected so that the required temperature for casting is achieved. This is particularly important for voluminous casts. We recom- mend phosphate bound investment materials. The manufacturer's process- ing instructions must be observed and the mixing ratios and preheating times accurately observed. We recommend you do not use any quick heat- ing processes (speed investment materials). The cast delay time must be kept as brief as possible. After casting, the cast object must be slowly cooled to room temperature and the object gently devested. We recommend gentle devestment in an ultrasonic bath with waterjet or stripping. After casting, suitable reworking reamers are available to remove/smooth out casting residues for reworking the screw seat and the shoulder contact area to the CAMLOG ® bar abutment. After trimming the bar, it is checked for a precision fit. Good hygiene capacity must be ensured. A distance of min. 2 mm to the gingiva must be main- tained to prevent insufficient cleaning and associated changes to the mu- cous membrane. Example: Milled bar construction Reworking reamer, for base for bar abutment, for the screw seat Ø 3.3/3.8/4.3 mm and 5.0/6.0 mm Reworking reamer, for base for bar abutment, for the plane surface/cone seat Ø 3.3/3.8/4.3 mm and 5.0/6.0 mm Reaming out the screw channel of the cast bar base Reaming out the inner cone and plane surface of the cast bar base Cast bar base Cast bar base Cast bar Cast bar The secondary framework, e.g. electroplating technique, is then fabricated. Example: Milled bar construction with secondary framework using the electroplating technique and tertiary structure
