Porcelain Crowns For many years there has been increasing patient demands for improved aesthetics in dental restorations. This demand has been especially strong in the area of front teeth that require crowns (caps). There have been many attempts to make an ALL porcelain crown. In other words, a crown that would not have a metal substructure under it. The reasons for wanting to eliminate the metal are primarily to get rid of the dark line at the very edge of the crown and to let more light pass through the porcelain. There have been MANY attempts over the past decade or more to provide "all porcelain" crowns. But despite what the manufacturers claim there have been problems with the "all porcelain" systems.
There have been improvements in metal based porcelain crowns as well.
Using gold metals instead of darker metals for a "warmth" of colour.
Better (much better) porcelains for better colours.
Better preparing of teeth so that there is sufficient porcelain at the biting edges for natural light to come through.
No metal exposed at any areas that can be seen .....what is referred to as "porcelain margins".
The two biggest pluses with metal/porcelain crowns are....
Much stronger than "all porcelain" (despite what the manufacturers claim).
Less tooth reduction usually.
Porcelain Veneers Chipped, cracked, worn teeth or
discoloured teeth. Veneers take very careful case planning so that the end result is exactly what the patient want. Though veneers require preparation of the teeth, it is generally much less than full crown preparation.
This is a very long lasting solution to aesthetics.
Problem Treatment Options Treatment Blending It is possible to use a combination of methods listed above to achieve the best possible results. An example of this is bleaching the teeth before placing veneers or bonding so that the lightest shade may be used. Another possibility is to have orthodontic care (braces), before attempting veneers or bonding.
The Crownless Dental Bridge
The CBW® bridge system has been developed to make crownless bridges without damaging sound teeth. Strong bridgework of single or multiple pontics is possible for replacing both anterior and posterior teeth.
It is increasingly considered to be unacceptable, by dentists as well as patients, to fully grind down healthy elements in order to fit a conventional bridge.
The Crownless Bridge Works (CBW®) anchor implant system has been developed to solve these problems.
Because this technique uses a combination of pin-anchoring and adhesive fitting, it has a number of advantages over etched bridges and conventional bridges:
In comparison with conventional bridges, hardly any healthy dental tissue is sacrificed Due to the pin-anchoring, the bridge element can withstand more pressure, which is distributed better between the abutments
Due to the lack of crown edges there is no periodontal pressure, as is the case with conventional bridges
Less interference with the existing occlusion and articulation due to the lack of abutment crowns or extensive retainers
The treatment is largely reversible and repairable
The treatment procedure is straightforward and involves less time than is the case with conventional bridges
The material costs are lower in comparison with conventional bridges
The treatment is not very stressful for the patient
Because this technique involves no crown edges or extensive metal retainers and the abutments are kept fully intact, it has major aesthetic advantages.
To avoid aesthetic problems, for instance in case of very thin abutment teeth in the front area, zirconium (a tooth colored ceramic material) anchors are available. Zirconium anchors are also very suitable in combination with fully ceramic bridge-elements (e.g. Empress æ).

Patients find these partials extremely comfortable, and durable without sacrificing aesthetics. The material can be used for all partials, unilateral removable replacements (Nesbits), and full dentures.
