Our case of the month for September 2022 is a lovely smile transformation done the Progressive Dentistry way with invisalign full, teeth whitening & a new front dental crown. When we plan these types of treatments, we often will look at whether the teeth are in the right place first. Why is this so important? Well the reason is simple. If the teeth are not in the right place or well aligned, any cosmetic treatment will be a big compromise. For instance, in the days gone by, there was a fad for porcelain veneers and crowns. If the teeth were wonky to start with, this would mean having to cut a lot of healthy tooth to make the ceramic veneers or crowns. This is not a good idea! For every heavily prepared tooth, around 17-20% of the nerves die. This means root canal treatment and a risk the tooth will not last a life time.
 

Our case of the month for April was one involving E Max crowns by Ivoclar, which is our opinion, give the best aesthetic results. In the past, tooth coloured dental crowns had a layer of metal underneath for strength with the ceramic bonded on the outside. Now these could look perfectly acceptable but there were issues. Having two layers means that more of the underlying tooth has to be cut down to accommodate the material. For any of you that has read any of our posts knows that we believe in minimally invasive dentistry, cutting away more tooth than necessary just does not sit right with us. Another issue with metal ceramic crowns is that the metal layer may become visible over time as the gums recede which gives that classic grey line around the tooth. Not very desirable. One of the main advantages of ceramic crowns is that there is no metal underneath and this grey line will never be an issue. 

The aesthetic qualities of E max crowns are second to none. Our case shows that the crowns can be fully customised with translucency at the edges, varying shades, light reflection and opaque areas to name a few. The skill of the dental technician plays a huge role here and we work with some excellent laboratories know for excellence. 

For our case, Ceramic Studios in Kensington made the wonderful E max crowns fully which were fully customised.
 

In the past, back teeth that required crowns or large fillings were given gold restorations. This was a sensible decision given that back teeth are used for chewing food and any crown or filling must therefore be able to withstand the high forces. Gold is an excellent material as it is extremely strong and biocompatible. However, it looks like gold and not like a tooth! Due to advanced in modern dentistry and materials, we are now able to provide back crowns that are completely tooth like and contain NO metal. These are called all ceramic crowns. They are also biocompatible and very strong. One example we like to use at Progressive Dentistry is the E-max crown. 

Below is an example of replacing a gold crown with an E-max all ceramic crown:
