Screw retained Dolder Bar for multiple implants The MIS “Multi-Unit” System is to be used with Biocom or Seven implants of standard or wide platforms. Using a screw retained Dolder Bar for multiple implants is a staged process. This manual illustrates the construction of a “cast-metal” framework (Dolder Bar) for multiple implants to retain a removable full denture with titanium riders, using the closed-tray impression technique. This manual is concisely written with clear “full-color” illustrations for each step. Component areas appear next to each step for clear and easy reference. Advantages Implants of standard and wide platforms can be used. ▪ Angulated abutments can be used. ▪ Suitable for limited interocclusal dimensions. ▪ Outstanding aesthetic phonetics and function. ▪ Economical, simple procedures. General Information1. Initial planning is of utmost importance. The dentist performing the prosthetic stage of the treatment should be an active participant, together with the surgeon, regarding implant choice, type of prosthesis, and the “three dimensional” positioning of the implant. It is a “prosthetic driven procedure.2. Dolder construction must be done with a parallelometer.3. Relining of dentures is more complex.4. The patient must be informed of proper denture use and hygiene.
