Exploring Park Avenue Dental’s CEREC® Service
By now, regular visitors to our Blog area should know that Park Avenue Dental is committed to providing our patients the latest technology in same-day crowns, fillings and tooth restoration. Known as CEREC® by Sirona Dental Systems, this is the world’s only platform for completing all ceramic dental restorations in one office visit – indeed, through the CEREC® machine, you can be in and out of our office in a single visit and boasting a permanent, all-ceramic crown, onlay or veneer.
What does this same day dentistry mean for you?
• Fewer injections
• Less drilling
• Less time out of your hectic schedule for dental implants
What is CEREC®?
CEREC® is an acronym for Chairside Economical Restoration of Esthetic Ceramics – in lay terms, this means a dentist can economically restore damaged teeth in a single appointment using a high-quality ceramic material matching the natural color of other teeth. CEREC® boasts two decades of clinical research and practical experience to support its success, with more than eight million restorations performed worldwide using this technology.
Pull back the curtain to find the wizard – that is, look inside the inner workings of the CEREC® system – and the advanced CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) technology comes to the forefront…a system which encompasses a camera, computer and milling machine in one instrument. At Park Avenue Dental, Dr. Michael Sherman, our recognized cosmetic dentist, uses a special camera to take an accurate picture of the damaged tooth, and this optical impression is transferred and displayed on a color computer monitor where he and his staff apply CAD tech to design the restoration. The CAM then takes over and automatically creates the restoration, and Dr. Sherman then bonds the new restoration to the surface of the old tooth…the whole process taking approximately just one hour.
The Benefits of CEREC®
• Single visit convenience
• Hi-tech accuracy
• Natural, tooth-colored restoration
• Biocompatible, anti-abrasive and plaque-resistant ceramic materials
• Metal and silver colored-free fillings
• Preservation of more healthy tooth material
• Extreme precision for lasting, natural results
Breaking Down the CEREC® Benefits
A tooth-colored restoration equates to the elimination of silver fillings that discolor your smile; using CEREC®, your filling is natural-looking, compatible with mouth tissue, anti-abrasive and even plaque-resistant. What’s more, dentists such as Dr. Sherman no longer need to create temporaries or take impressions and forward them to a lab – the traditional second visit has been eliminated. The CEREC approach boasts over a decade of clinical research and documentation to support it, and the restorations have been proven to be precise, safe and effective.
One of the most talked-about benefits of CEREC® is definitely its single appointment approach. While most dental restorative methods require more than one visit to the office, the CEREC® experience is completed in one single appointment from start to finish. Traditionally, the first visit to a dentist’s office included an anesthesia injection, a tooth preparation, an impression and a temporary restoration put on the tooth. The second appointment, normally a couple of weeks later, usually entailed an injection, the removal of the temporary – if it didn’t fall off – and a permanent restoration put on. But why go to the dentist for a second time if you don’t have to?
With CEREC®, it’s also all about the utilization of the finest dental materials. Compared to many years ago when dentists had few options to repair decayed and damaged teeth other than amalgam, gold and other metals, CEREC® uses strong, tooth-colored ceramic materials to restore your teeth to their natural strength, beauty and function. These materials, as used by Dr. Sherman and his staff, closely match the composition of natural tooth structure – this means that when you eat hot food and then drink something cold, the restoration and tooth expand and contract at nearly equal rates. The materials, meanwhile, are chemically bonded to your tooth so Park Avenue Dental can save as much healthy tooth tissue as possible while providing you with a dental restoration that, in turn, actually strengthens your tooth.
Did You Know?
The CEREC® method was developed by Professor Werner H. Mormann and Dr. Marco Brandestini at the University of Zurich in 1980, with the first patient treated using VITABLOCS Mark I ceramic blocks in 1985. Siemens obtained the license to market and further develop the CEREC® method in 1986 and launched the world’s first CAD/CAM platform in dentistry in the form of CEREC® 1 in 1987. The CEREC 2 system, introduced in ’94, consisted of inlays, onlays, crowns and veneers, and in 1997 the sale of Siemens AG’s dental division yielded the company Sirona.
In 2009, Sirona switched to a new imaging technology with the CEREC® Bluecam, based on shortwave blue light, which significantly increased the level of precision as compared to the previous 3D camera method. Since 2010, the implementation of Biogeneric has made it possible to individually reconstruct the occlusal surfaces of damaged or missing teeth while achieving a natural look.
The latest development in this area comes in the form of the CEREC Omnicam intraoral camera, introduced to the market in 2012, facilitating powder-free digital impressions in natural colors. As of October 2013, approximately 38,000 dentists worldwide have used the CEREC method, producing some 6.9 million restorations each year.
The Science Behind the Materials
Silicate ceramics – feldspar and glass ceramics – in particular have proven ideal for single tooth restorations (inlays, onlays, crowns and veneers) in the front and on the sides of the mouth. Conversely, low flexural strength of 100 to 450 megapascals makes adhesive attachment necessary; lithium disillicate is a glass ceramic that exhibits the material characteristics of oxide ceramics. This incredibly strong, translucent material – oxide ceramics in particular – is ideal for manufacturing high-strength bridge frameworks and crown copings in the front and sides of the mouth. Flexural strength of 300 to 600 megapascals (infiltration ceramics) or 600 to 1,300 megapascals (polycrystalline oxide ceramics) guarantees a high level of long-lasting durability and breaking strength.
Additional CEREC® Benefits
Okay, so we know CEREC® technology makes it possible to produce and integrate ceramic restorations in a single dental appointment, and that now it’s possible to reduce the amount of follow-up work and time-intensive occlusion adjustment that was often necessary in the past. But according to studies, the 10-year lifespan of CEREC inlays polished and milled by computer aid is not only significantly longer than that of gold inlays, but also exceeds that of individually laboratory-manufactured ceramic inlays. Further clinical studies have revealed that the success rate of CEREC restorations is 95.5-percent following a period of nine years and 84-percent after 18 years.
The digital mapping technology inherent in CEREC® that charts the inside of the patient’s mouth accurately – down to the last detail – ensures that there remains no issue with inaccurate dental impressions that lead the patient to experience discomfort with unsightly molds and unnecessary debris in their oral cavities.
Other Potential Applications for CEREC®
In conjunction with three-dimensional X-ray technology, CEREC® has also been used for implants since 2009. The dentist can fuse the CAD/CAM planning based on CEREC® with 3D X-ray data to coordinate the surgical and prosthetic implant planning and achieve the intended treatment results. Based on what has been dubbed “integrated implantology,” the dental professional is able to order the drilling templates from SiCat – a drilling template manufacturer – or if they have their own milling machine, produce them at their own office using CEREC® Guide.
