Advanced Technology – CEREC

Precision Dentistry

When you seek care at our office, you are assured that Dr. Hashimoto and his staff utilize the latest in technology to enhance the quality and fit for your dental care. Our practice uses high power magnification to enhance the precision of patient care. Dentistry is micro-surgery. Using magnification that is similar to the one a surgeon uses enables us to create dental restorations with incredibly precise fit and finish. You just can’t fulfill that level of care with the naked eye. In addition to allowing precise, close-up work, the magnfier directs a beam of light directly on the teeth, minimizing glare for you. Many dentists use air-driven “hand-pieces” (the dental term for “drills”). While acceptable for many procedures, these “whiney sounding” air-powered hand pieces all have a degree of non-concentricity; they do not rotate perfectly smoothly. For the most precise aspects of restorative procedures, we use electric hand-pieces. This results in extraordinarily precise interfaces between your tooth and your new restoration ( crown, veneer, or filling). This will bring more comfort to you as well. With a more precise tool, there is less vibration and less noise.

Digital Imaging

Dr. Hashimoto chooses carefully which and when radiographs are taken. There are many guidelines that we follow. Radiographs allow us to see everything we cannot see with our own eyes. Radiographs enable us to detect cavities in between your teeth, determine bone level, and analyze the health of your bone. We can also examine the roots and nerves of teeth, diagnose lesions such as cysts or tumors, as well as assess damage when trauma occurs. Dental radiographs are invaluable aids in diagnosing, treating, and maintaining dental health. Exposure time for dental radiographs is extremely minimal. Dr. Hashimoto utilizes Digital Imaging Technologies within the office. With digital imaging, exposure time is about 50 percent less when compared to traditional radiographs. Digital imaging can also help us retrieve valuable diagnostic information. We may be able to see cavities better. Digital imaging allows us to store patient images, and enables us to quickly and easily transfer them to specialists or insurance companies.

Digital X-Rays:

Digital X-rays offer more precision since we view the image on a computer monitor, instead of holding up a 35mm film up to the light. Digital X-rays results in 1/6th the radiation exposure to you.

Laser Dentistry

For patients who do not look forward to needles, drilling, or numbness, Laser Dentistry may be the right choice. Laser dentistry is one of dentistry’s latest advances. The laser delivers energy in the form of light. Depending on the intended result, this energy travels at different wavelengths and is absorbed by a “target.” In dentistry, these targets can be enamel, decay, gum tissue, or whitening enhancers. Each one absorbs a different wavelength of light while reflecting others. Laser dentistry can be used for both tooth and soft tissue related procedures. Oftentimes no local anesthesia is required. Unlike with the dental drill, with laser dentistry there is no heat or vibration, making the procedure quite comfortable for most patients. For soft tissue (surgical) procedures it eliminates the need for suturing and healing is much faster. Lasers can be used to diagnose cavities. They can find hidden decay in teeth in early stages, and in some cases the decay can be reversed through hygiene and fluoride treatment and may never need filling.

Areas of dental care that benefit from laser technology:

Dental lasers have been shown to be safe and effective for treating both children and adults.

Intraoral Camera

Many patients, especially younger patients, are very familiar with the latest technology and are comfortable with the high tech practice. Computers and TV screens are their primary method of information processing. Dr. Hashimoto utilizes intraoral camera technology that helps enhance your understanding of your diagnosis. An intraoral camera is a very small camera – in some cases, just a few millimeters long. An intraoral camera allows our practice to view clear, precise images of your mouth, teeth and gums, in order for us to accurately make a diagnosis. With clear, defined, enlarged images, you see details that may be missed by standard mirror examinations. This can mean faster diagnosis with less chair-time for you! Intra oral cameras also enable our practice to save your images in our office computer to provide a permanent record of treatments. These images can be printed for you, other specialists, and your lab or insurance companies.

Cerec

The CEREC Procedure

Let’s face it, very few of us have perfect teeth, free of decay and fillings. You can probably see a filling or two in your own mouth, which do just that — “fill” a cavity, or hole, in your tooth left from the excavation of decayed tooth structure. In many cases, those fillings are made of metal material and can go bad, weaken the tooth, or get additional decay under or around it. In fact, 1.2 billion of these metal fillings will need to be replaced in the next 10 years. CEREC is a method used by thousands of dentists worldwide since 1987 not only to replace these fillings, but also to restore any tooth that is decayed, weakened, broken, etc. to its natural strength and beauty. Better yet, it’s done with all-ceramic materials that are tooth-colored in a single appointment!

Exam and Preparation

First, your Dentist examines the tooth and determines the appropriate treatment. It could be a simple filling, or a full crown, depending on how much healthy tooth structure is remaining and the clinical judgment of your Dentist. Next, he or she administers an anesthetic and prepares your tooth for the restoration, removing decayed and weakened tooth tissue. This preparation is just like he or she would do for many other restorative techniques.

Optical Impression

Then, your Dentist takes an Optical Impression of the prepared tooth. Instead of filling a tray with impression “goop” that you must bite into and hold in your mouth until it hardens, your Dentist coats the tooth with a non-toxic, tasteless powder. A camera is then used to take a digital picture of your tooth. This whole Optical Impression process takes only a minute or two.

No Temporaries

Next, the CEREC machine helps the Dentist create the restoration for your tooth. The CEREC 3D software takes the digital picture and converts it into a 3-dimensional virtual model on the computer screen. Your Dentist then uses his or her dental expertise to design the restoration using the CEREC 3D computer program. Within a few minutes, your Dentist clicks a button, and the restoration design data is sent to a separate milling machine in the office. A ceramic block that matches your tooth shade is placed in the milling machine. About 5-30 minutes later, your all-ceramic, tooth-colored restoration is finished and ready to bond in place. Finally, your Dentist tries the restoration in your mouth to ensure proper fit and bite. The restoration is then polished and bonded to the prepared tooth. Your tooth is restored with no “temporary” or return trip necessary. All of this is done in a single appointment! Ask us about CEREC today.

What is CEREC? CEREC is an acronym…

  • Chairside: The technology is in the dental operatory and used while you are in the chair
  • Economical: The procedure is economical for both dentist and patient
  • Restorations: The procedure restores your tooth to its natural beauty, function, and strength
  • Esthetic: The restorations are metal-free and tooth-colored
  • Ceramic: High-strength ceramics are used that are close in composition to your natural tooth structure.

CEREC is an advanced dental restorative system that allows your dentist to restore decayed teeth, place crowns, remove defective amalgam fillings, or place cosmetic veneers in just one appointment. This allows you to have the highest quality, most lifelike dental restorations in just one visit to the dentist…in, out, and on with your busy life.

CEREC Acquisition Unit

The CEREC Acquisition Unit is mobile and houses a medical grade computer and the CEREC camera. Your dentist uses the camera to take a digital picture of your prepared tooth. This picture is used instead of a traditional impression. This means no impression tray and material for you to gag on. The computer and CEREC 3D software converts the digital picture to a three-dimensional virtual model of your prepped tooth. Your dentist then designs your restoration right on screen using the software while you wait (and watch!). This software can assist your dentist with designing any single tooth restoration: crowns, inlays (fillings), onlays (partial crowns), and veneers. Once your dentist has designed your restoration (usually about 5 minutes), he or she clicks a button, and the design data is communicated via a wireless radio signal to the CEREC Milling Unit.

CEREC Milling Unit

Your dentist or dental assistant selects a ceramic block that matches the shade of the tooth being repaired. He or she then inserts the block into the Milling Unit. The data from the Acquisition Unit is used to direct two diamond-coated burs to carve the block into the indicated shape of the restoration. This process usually takes 8 to 18 minutes depending on the size and type of restoration. After the milling is finished, your dentist polishes the finished filling or crown and bonds it into place.
