ARE THERE ANY CONCERNS AND WHAT IS THE EXPERIENCE OF THE PATIENTS?
Very often we face the question of whether it is possible to do all ceramic crowns if the patient had already done metal ceramic crowns and now wishes to change them? The answer is yes, it is possible, but there are some concerns. If you have read this carefully, you already know that the method of tooth preparation is completely different for the all ceramic and metal ceramic crown. This means that after the tooth has already been filed down 2 mm under the gums for the metal ceramic crown, the edge for all ceramic crown will also have to be 2 mm. This means that we no longer have that gentle contact of the gums and the all ceramic crown. Therefore, by replacing the crown, it is sometimes possible that the gums respond to the all ceramic crown as they did to the metal ceramic one, reacting with inflammation and mild bleeding when brushing your teeth. Therefore, in addition to the classic toothbrush, it is necessary to include electric dental irrigators in your daily hygiene routine, a tooth cleaning machines using water pressure. This way, every minor problem can be regulated.
The second common question is about the treated teeth that have darkened long time ago, so patients wonder if such dark tooth will make the all ceramic crown look gray. We can say that it will not, and this is the moment when a team of experienced dental technicians takes its place. It is necessary to have photographs of the current state of the patient’s teeth, determining the color of the adjacent teeth, so that the ceramic base of this darkened tooth can be done in 2 shades brighter color compared to the color of adjacent teeth. After the application of ceramics in the final phase and the final glaze there will be no differences between the current living and treated teeth and an aesthetic excellent solution is reached. If this treated tooth has a large tooth mass loss and the all ceramic crown can not be done, then it is necessary to make a reinforcement for which bonding made of glass is used, the so-called fiberglass posts. Such bonding is transparent, very firm and is cemented into the tooth root canal. An impression for the all ceramic crown is taken over it, and you still get to keep the aesthetics.
Molded metal posts which are cemented on the teeth on which we would like to place the all ceramic crowns are not an ideal base for them and no one can guarantee the ideal aesthetics of such solution. It is necessary to consider carefully whether there are any other solutions for this case.
