Metal free crowns- no black lines

If you have a dental crown, this article is for you. In the old days of dentistry, there were only a few types of crown. Namely: 1. Metal crowns 2. Gold crowns 3. Porcelain bonded to metal crowns Now metal and gold crowns have their place, but they do not look like teeth! Porcelain bonded to metal crowns were devised to overcome this problem and still provide adequate strength. Over the years, these have proven to be a great success on the whole. However, they still contain metal and all too often a black line would appear around the gum line due to gum recession (ever heard of the term 'long in the tooth'?) At Progressive Dentistry, we aim to use metal free crowns wherever possible. There are a number of metal free crowns now available which have certain indications for the area required. For example, zirconia crowns are extremely strong and durable with compressive strengths of 900MPa. These are excellent at the back of the mouth. Empress E max crowns are highly aesthetic and are our choice for front teeth. Have a look at some photos:

The choice is clear- metal free! If you have crowns and would like replaced due to the dreaded black line or would like more aesthetic crowns, please do not hesitate to contact us. Treatment completed by Dr Nissit Patel. Laboratory work completed by Andy Foster.

Case of the Month April 2021- Ceramic Crowns

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 inv… READ MORE

Dental Crowns: What Are They, Procedure & Cost

Dental crowns are one of the most common dental procedures but many people are not aware what a crown is exactly.

A dental crown is needed when the underlying tooth is heavily broken down and a routine filling will not be sufficient.

Dental implants- all ceramic crowns

As you will be aware, dental implants are the best way to replace missing teeth. Whether you are missing one, several or all of your teeth, dental implants can help. In the past, dental implant crowns (the actual tooth replacement) was a combination of a titanium abutment (screwed into the implant) and a porcelain fused to metal crown. This was fine and provided a perfectly good, robust result. However, for front teeth especially, the aesthetics of such restorations were possibly not great. Today, we are … READ MORE

All ceramic crowns- no black lines

In general, we adopt a metal free policy wherever possible. This is especially the case at the front of the mouth where aesthetics are highly important. We now routinely use all ceramic crowns for front teeth. The great advantage of these crowns is that with no metal, the aesthetics are excellent and there is no issue with the dreaded 'black' line visible at the gum level. The photograph below shows a super close up view of some front teeth. One of them has an all ceramic crown. Can you tell which one? W… READ MORE
