This course will examine in detail, the criteria and design considerations utilized in the “reverse engineering” concept as well as fabrication techniques for state-of-the-art CAD/CAM milled titanium bar prostheses for treatment of the edentulous patient.
The course will include Nobel optical scanner instructional overview and hands-on participation in the use of NobelProcera design software for virtual custom bar design.
Participants will fabricate screw retained “resin base-bars” on which to diagnostically set denture teeth using Ivoclar Phonares II Nano-hybrid composite resin denture teeth. Proper positioning of denture teeth for occlusal schemes specific to implant supported restorations, which are critical to long term durability of the prostheses and will be discussed.
Detailed processing techniques for screw-retained hybrids (Fixed-detachables), will be presented and demonstrated utilizing Ivoclar’s state-of-the-art “Ivobase” injection processing system.
Other considerations specific to this arena of technology will be briefly reviewed including various design concepts and comparisons for hybrid bar styles such as Wrap-Around vs. Montreal, as well as common pitfalls such as inadequate vertical space, facially divergent implants, and “unfriendly” implant systems.
Materials and component science to insure state-of-the-art accuracy and durability will be discussed in depth.
Participants that have already completed this course may opt for the new advanced course that examines design and processing techniques specific to attached over-denture bar restorations as well as Nobel Clinician digital planning software for implant placement, the All-on-4™ and “Immediate Load Conversion” concepts from the Laboratory perspective.
