In this ever-expanding digital dental world, it is now possible for any size lab to offer one day turn around on simple cases, but generally 2 to 3-day turn-around time for anterior (or posterior) world class indirect ceramic veneer restorations that is just not possible with analog technology alone or with current chair side technology alone. With new scanners, and Laboratory 4 and 5 Axis milling machines, state of the Art printers it is possible for a dentist to prepare an anterior veneer case in the morning and have the case delivered in the afternoon with the concept developed by Dr McLaren called the Digital Dental Team. Current Technology allows direct scanning of preparations, or for the many dentists that don’t own scanners scanning the inside of an impression. Thus, this system allows the dentist to enter the “DDT” workflow conventionally or more ideally digitally.
The second part of the DDT concept is the amazing improvement in digital printers that now rival Type 4 Dental stone. There are several workflow paths that can be taken. For this course the path that will be taken, the master cast and master dies are printed in the same way, veneers are designed in a cad program they are then printed in a castable wax. They are invested in a speed investment and pressed in a high strength glass ceramic. The important part of the Digital Dental team is the high quality of the dense glass ceramics that can be layered, or used full contour. The original Vita material is an excellent material, along with the more recent Empress CAD, they work outstanding for this DDT technique. Lithium Disilicate or Zirconium Reinforced Lithium Silicate can also be used but require extra firings to completely crystallize and which makes it more challenging to do in one day.
For speed investment and pressing of machined wax E.Max has been a market leader, but the course authors still believe strongly in pressable “feldspathic glass” materials e.g. Empress and Vita Blocks. The last part of the DDT concept is what I like to call the “ENAMELIZER” and “FINISHER”. It is the magic that only a talented technician can apply to optimized or make a restoration look real. With for aforementioned technology, the machined veneers can be done very quickly after scanning either preps or impressions. The Enamelizer would take it from there, meaning adding small pieces of porcelain, maybe some color highlights, a “halo”, then a quick fire, the “finisher” would do a quick contour, stain and glaze. Also, possible is to used the materials “monolithic” and put natural texture and then surface paint, glaze, and polish the restoration. This technique can be just as esthetic as the micro-layering technique but can be done in a much shorter time.
So, from this DDT concept a 3-day course has been designed. This hands-on fast paced comprehensive three-day program is designed for both the treating dentist, the digital designer and the technician who will do the “Enamelizing” and “finishing”, i.e. the ‘WHOLE DDT” Join Dr. Ed McLaren DDS MDC, Dr Armen Mirzayan, Jed Archibald for this exciting and fast paced course.
