CAMLOG LOGFIT Prosthetic System

Logfit ® Prosthetic System for cementable crown and bridge restorations WAX-UP The framework is waxed up in the usual manner according to the design of the «reduced crown shape». Take care that adequate and uniform ceramic layer can be achieved for the veneering. The minimum wax thickness over the plastic coping should be at least 0.3 mm. Do not cast over the delicate coping edge. VERTICAL DIMENSION TO THE THE OCCLUSION LEVEL Information from implantologists for the length of implants used plays an important role in the prosthetic planning respectively restoration. Loading of the implant-bone interface is a result of the leverage relation generated by osseointegration-related resistance to the prosthesis load arm (equiva- lent to the supracrestal implant length plus the length of the crown above the implant shoulder). If IL is smaller than CL, then the load must be reduced (e.g. through prosthetic splinting). The length ratio of single crown to im- plant should be max. 0.8:1. The ideal framework form can be controlled with a previously prepared silicone index. TIP: To prevent non-axial loads and over contouring in the posterior area, we recommend reducing the wax-up to premolar size. IMPORTANT NOTE When burning out the casting muffle, swelling may occur due to the ther- mal expansion of the plastic and damage the investment compound in the area of the plastic coping. This can cause investment compound to be included in the casting metal. Therefore, a minimum wax thickness of 0.3 mm should be applied to the plastic coping. When heating, the wax softens first and gives the plastic enough space to expand. IL IL CL IL = Implant Length CL = Crown Length CL
