Why Choose Cerec Restorations (same day crowns)

Cerec is a new way of filling teeth and replacing old restorations . It can be used for large filling crowns and even bridges.

Why do patients love it? The CadCam system cerec uses means that you can have your tooth prepared and the crown or inlay ( large filling) created in our surgery and fitted in our surgery in a single visit. There are no impressions required and no need for the temporary crown which many patients understandably worry may come off between visits or reveal the fact they are undergoing treatment.

This is all made possible by the technology this system uses. In short the tooth is prepared as normal, then a 3D optical impression (scan) is recorded of your tooth, using a small specialised camera designed to fit neatly in your mouth. This replaces the need for the old putty/wash impressions many patients associate with dental treatment and orthodontics. The camera also scans the teeth which will meet the crown when you chew and constructs a tooth coloured crown/inlay to fit exactly making it immediately comfortable to bite on requiring minimal if any adjustment. Our patients can then leave the surgery with their new crown or inlay fitted in harmonious function with their natural teeth.

The Advantages of CEREC;

  1. A better fitting inlay or crown, for the first time in dentistry we are able to construct a crown made to fit the tooth. There are a number of stages involved with preparing crowns and inlays in the traditional way and many of these stages can lead to inaccuracies . These include taking a mould in the first instance , transporting it to the laboratory when shrinkage can occur and finally making a replica stone model on which to construct the crown creates even further possibility of distortion. Finally a crown is constructed in the laboratory to fit the model created, dental technicians are very good and will create a perfect fit to the model however there is always a possibility that the crown may not fit the actual tooth in your mouth exactly since the model may be slightly inaccurate. This is frustrating for patients, dentists and dental technicians who have all played their part diligently. The optical impression taken by the CEREC avoids these traditional limitations since we are working to the exact dimensions of the tooth in the mouth, the inlay or crown is then constructed to fit the tooth not a model.
  2. The inlay or crown is prepped, milled and fitted in one visit. This means only one anaesthetic is required which is always an advantage for patients.There is no requirement for a temporary crown or inlay. Temporary crowns and inlays are placed on the prepared tooth between visits while the laboratory is creating the final restoration. They have two important functions, they protect the tooth from sensitivity and bacteria but they also ensure things remain stable between visits. Teeth can move if not covered which is clearly not helpful in this scenario as it may compromise fit . A good temporary will ensure this does not happen. However despite our best efforts sometimes teeth move very slightly and the crown requires a surface adjustment when fitting. Every effort is made to make a temporary crown you are happy with aesthetically however it is a temporary and therefore cannot be completely customised to your smile in the fashion a permanent crown can. There is also undoubtedly the chance that your temporary could come out meaning an unexpected visit to the surgery to have it rebonded. Murphy’s Law states that a temporary will debond at the least convenient time!!
  3. This is an adhesive dental system. This simply means that we are using modern tooth coloured material which facilitates using modern dental adhesive technology. Essentially we can “stick” the restoration to your tooth and the tooth is not required to be shaped in any particular fashion to ensure the restoration locks in. This freedom allows us so retain the maximum amount of your natural tooth. This is called Biomimetic Dentistry, that protects the integrity of the tooth, producing a restoration that seeks to mimic what was there and so provide a strong long-lasting restoration.
