Step 2 in RPD Framework Design: Drawing on the Cast
Posted on 10/19/2011
After surveying the cast, the case is ready for the framework design. Preferably, the design should be drawn on a diagnostic cast. This allows the technician to transfer the design to the working model using the normal procedures that are practiced in that particular lab.
While drawings on casts are ideal, in many cases they are just not practical due to time constraints faced by the doctor. In such cases, drawings on the Rx are helpful when accompanied by written instructions. Drawings on paper alone are often ambiguous and lead to common errors such as incorrect clasp design.
For complex frameworks, we highly suggest to ask the lab for a digital image of the waxup before casting. The photo below is an example of such a waxup. With an image, the doctor can easily correct simple mistakes and save a great deal of time and aggravation. At Streamline, we offer waxup design images free for any case and the design images can be approved on our website or through email.
