A common scenario leading to a single visit porcelain restoration is a patient who breaks a tooth over the weekend on a hard piece of food or while playing sport. The person is then in severe pain due to exposed cracked tooth and manages to see the dentist on Monday morning. Instead of placing a temporary filling and rescheduling them for a crown or onlays at a later date we are able to prepare the tooth and create a ceramic tooth coloured restoration before the patient has to return to work.
This is a possibility today simply because of "BONDED CERAMICS" or CEREC.
With CEREC at your dentist's side, you can be in and out in a single visit with a permanent (long term), all ceramic crown, inlay, or veneer! For you, as a patient, this means fewer injections/needles, less drilling, no messy impressions and less time out of your hectic schedule.
We understand you as a patient want the highest quality restoration that will last, look good, are metal free and can be done with as little dental visits as possible. With the new 3D cerec software the highest possible precision restoration can be done in less than 1 hour for a single tooth from start to finish.
Most dental professionals and patients would agree that metal based restorations should be avoided if at all possible. By contrast, all-ceramic materials offer outstanding benefits. They are biocompatible, biometric, display tooth-like mechanical properties and allow you to conserve much more natural tooth tissue. CEREC is a stepping stone in modern ceramic dentistry.
When teeth wear down or fracture from trauma or develop a large cavity from decay, dentists have to use some type of artificial material for repair. 20 years ago dentists used silver and mercury-based amalgam for fillings, cast gold for inlays and onlays, and many different types of 'crowns' to repair teeth. With the advent of resin technology in the last 10 years tooth coloured restorations have become more favourable option and can sometimes be straightforward economical solutions. We also call these plastic fillings or composite fillings. However, these are short to middle term solutions, especially in teeth which do not have a lot of strength left in them or have more than 2-3 walls missing. This is where cerec or bonded ceramics can help restore broken down teeth to normal function and aesthetics with either a crown or an onlay.
A CEREC tooth restoration isn't just convenient, With CEREC, your dentist can use strong, tooth coloured ceramic materials to restore your teeth to their natural strength, beauty, and function. These materials also closely match the composition of the natural tooth structure. This means when you eat hot food and then drink something cold, the restoration and tooth expand and contract at almost equal rates. So, pain and sensitivity are reduced and you can go on with your life. Also, the materials used are chemically bonded to your tooth, so your dentist can save as much healthy tooth tissue as possible while providing you with a dental restoration that strengthens your tooth, looks natural and seals the tooth in the process to prevent underlying nerve irritation.
We as your dentist can use CEREC for more than just crowns and fillings. CEREC is capable of producing any single tooth restoration. Chipped or discoloured front teeth can be repaired with beautiful CEREC porcelain front crowns or veneers. Your smile is one of your biggest assets and having a smile designed with CEREC veneers can enhance it further.
Healthy, natural teeth have a highly glossy, lustrous appearance with an extremely tough surface (the hardest in the human body). CEREC is one of the most biometric materials available today. Plastic fillings can be made to look aesthetically pleasing but are not as durable over the life of a tooth, and may require replacement more often, roughly every 2-5 years.
Hot drinks and cold foods make acrylic and metal fillings expand and contract much more than a tooth, gradually opening 'micro-gaps' at the edges of fillings. This is one of the main reasons for early failure of traditional materials. 'Micro-leakage' caused by these very small gaps can also cause tooth sensitivity, staining and new decay.
The surface of teeth naturally wear down with time. Silver fillings and metal restorations can be too abrasive and can damage your natural teeth. It is better to use a dental material that wears the same way as a tooth - crowns and ceramic restorations made from CEREC have been engineered so this happens as naturally as possible as opposed to silver amalgam or hard metals that can be more abrasive to opposing tooth structure.
Decay weakens teeth by creating cavities and defects in the natural shape of a tooth. With 3D modelling and computer designed restorations, a precise restoration can be made allowing a secure bond between dental ceramic and natural tooth the first time. Dental bonding using ceramic (CEREC) can return 93% of the original strength to a damaged tooth.
Your dentist will remove decay and old filling material, at the same time smoothing your tooth to make the right shape for the new restoration. A dental impression of silicone rubber makes a mould-this sets in your mouth and makes an impression of the fine details of your teeth. Dental technicians make inlays, onlays and crowns for dentists using the mould made from the dental impression. It normally takes 2 weeks before the dentist can complete the treatment. Patients need to wear a temporary crown during the construction period which sometimes is irritating and can fall out when eating some sticky foods.
Using a highly specialised camera attached to a computer, a series of images are captured inside your mouth. These are processed and result in a virtual model of your tooth visible on the computer screen. Using a library of possible shapes and uniquely-designed software tools, the 3-D computer version of the new restoration is produced. The 3-D model is electronically transmitted to the 'milling unit', where diamond-coated instruments shape a ceramic block to form the new restoration. This process takes place chair-side, and lasts only minutes.
Worldwide, a CEREC restoration is placed every 20 seconds. With a history of nearly 20 years, this equipment has helped dentists place over 12 million restorations. Using metal free materials that are the closest to your natural enamel, CEREC gives you the highest quality restorative care.
