show more/lessThe use of digital techniques has found its way in modern dentistry, although it is still not common standard.
This overview will demonstrate the possibilities of a complete virtual planning, starting from pre-implantology. With 3-D planning as a intermediate step and individual abutments as final stage before prosthetic work this lecture will show the capabilities that the use of latest technologies could offer the modern surgeon.
The complete procedure will be demonstrated on clinical cases step by step.
- Showing the importance of pre-operative planning
- Providing an overview of CAD/CAM possibilities
- Demonstrating the complete treatment incl. intermediate steps
- Definition of the benefits for the surgeon/patients
show more/lessAll-ceramic restorations provide better esthetics and biocompatibility than metal ceramics. However, many early all-ceramic systems were plagued by relatively low fracture strengths and an uncertain long-term clinical behaviour.
Since many years dental technicians have manipulated metals and ceramics using the same traditional methods. These methods are time-consuming, sensitive and unpredictable. With multiple steps, many variables and a need for innate hand-eye coordination skills. For many years, CAD/CAM dental restorations have been considered novel, on the cutting edge of treatment technologies, but expensive and somehow not for everyone. At the beginning, some of the first blocks were also not really esthetic. Today, with the latest developments, we can confirm the predictability and add the reduction in prices, which make this technology affordable for almost everyone and the simplicity and esthetics of materials launched recently.
On one hand, current CAD/CAM high-strength ceramic materials provide fracture strength and fracture toughness up to ten times higher than traditional ceramic materials, on the other hand, it is possible to mill a block of ceramic and get a polychromatic crown or veneer that with minimum staining or just by polishing can achieve an almost identical appearance to a natural tooth. Lithium disilicate blocks with a translucency close to the most esthetic restoration done with the refractory die technique with powder/liquid ceramics are a reality.
The materials and the technology is there! But we need to know first that they exist and what is possible to achieve with them, in order to think over the suitable material for each particular case.
The lecture will try to give the basic knowledge to understand how different materials are processed, and based on their mechanical and esthetic properties predict how they will behave in our patients mouth. It will try to clear up the dilemma of which CAD/CAM ceramic is suitable for each indication and in which cases high translucent, low translucent or more opaque blocks should be used based on fully documented clinical cases on high definition from A to Z.
show more/lessHaving successfully negotiated the planning, preparation, and prescription of your CAD/CAM restoration, the cementation stage represents the culmination of all your efforts, like a climber reaching the top of the mountain.
This stage is not difficult, but a successful outcome need as much care as the preceding stages, specially with all-ceramics materials. Once a restoration is cemented there is no chance for modification or correction. You have to get it right from the first time.
The way we prepare will define the fit of the restoration and at the same time it will have an influence on the cementation line and the stress transferred to the interface.
Resin cements have been available to the dental profession for two decades, but the number of clinical steps involved and their technique sensitivity have made resin cementation a complex process. We already know about the superiority of clinical and physical properties of resin cements compared to phosphate, polycarboxylate and glass-ionomer cements. On feldspathic or leucite reinforced blocks, the use of them is mandatory anyway!
A few years ago, self-adhesive resin cements were launch to the dental profession, claiming to be the best compromise between both worlds, almost as fast and simple as the conventional cements, but with comparable mechanical properties to the resin cements. Evidence show us that some of those claims became truth and others not. Can we use them safely for all the indications? Do we really have an advantage using them? Which are their drawbacks?
The lecture will present, a brief timeline of different cements, problems associated with cementation, indications for the different materials, light curing techniques and tipical mistakes during cementation.
Step by step procedures will be shown with fully documented clinical cases on high definition.
