Prosthodontics, Fixed & Dental Technology

We have a problem! Laboratory technicians report that most impressions for crowns and fixed prostheses do not have adequate representation of tooth preparation margins. Dr. Christensen shows how every dentist can make perfect impressions almost every time! Subject included are reasons for inadequate impressions; making gingival healthy pre-operatively; great impression trays; the best impression materials; predictable tissue management; coping with difficult impressions; and a detailed, close-up clinical procedure for perfect impressions.

Zirconia-based restorations are replacing PFM and changing constantly! Update yourself in this important area with this excellent DVD. The all-ceramic indirect restorative revolution is providing both strength and esthetic excellence that was nonexistent in the past. Both high-strength glass or zirconia substructures are now successful. Understand the indications, strengths, and limitations of all-ceramic restorations; the benefits of the "press-to-zirconia" technique; and the advantages of one overlay ceramic.

Most dentists accomplish at least some complex fixed prosthodontic cases, but many practitioners have not had an overall rehabilitation course. There are numerous techniques and sequences to rehabilitate these debilitated patients. Some procedures are time-consuming, difficult and impractical; while others are relatively simple, logical and effective.

Many recent changes for indirect tooth restoration preparations have been proven. Dental laboratories report that incorrect tooth preparations are commonly observed. Additionally, the profession is changing rapidly towards using more all-ceramic crowns and fixed prostheses, and ceramic veneers, resulting in tooth preparations that require different characteristics from the past and optimal design for long-term service.

Great impressions are necessary to create maximum effectiveness in fixed and removable restorations, and you can make them! However, our lab colleagues tell us that excellent impressions are a rarity. This presentation includes several methods to make perfect impressions for crowns and fixed-prostheses almost every time. Removable partial dentures can be excellent restorations if the impressions are highly accurate with chewing pressure on the edentulous areas simulating actual use. The simple impression technique demonstrated shows how to accomplish just that!

Major changes have occurred in this area in the recent past! You know the evolution away from custom cast posts, but did you know the reasons for change from metal prefabs to fiber-reinforced, resin-based composite posts? Some bonding agents are not working with popular composite build-up materials. Many dentists are placing posts where they are not needed. Some practitioners are placing posts too deeply into tooth, and many are avoiding use of pin retention when it should be used.
