Our Technology

When you seek care at our office, you are assured that Dr. Knollman and his staff utilize the latest in technology to enhance the quality and comfort of your dental care.

Digital Imaging

Intraoral Image Quality and Dose Summary of Results

Dental Intraoral Image Quality
and Dose Summary of Results

Dr. Knollman chooses carefully which and when radiographs are taken. There are many guidelines that we follow. Radiographs allow us to see many things 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. Knollman utilizes digital imaging technologies within the office. With digital imaging, exposure time is about 90 percent less when compared to traditional radiographs.

Digital imaging allows us to store patient images, and enables us to quickly and easily transfer them to specialists or insurance companies.

The need for additional x-rays is negated; reducing your exposure and expense. Digital X-rays offer more precision since we view the image on a computer monitor,

The Wand© Computer Controlled Anesthesia System

STA – Single Tooth Anesthesia

The Wand© - STA Anesthesia System applies anesthesia to a single tooth - Asheville Dentist Dr Knollman

Finally dental injections can be painless, as dentists use the Wand to deliver anesthesia without pain. It’s so gentle it’s even ideal for use on children.

Dental Anesthesia in the Computer Age

A computer helps guide the dentist to the exact spot where you need anesthesia. The Wand© works more quickly than the conventional method so that you will spend less waiting time in the chair. For some uses, in fact, it works almost instantly.

The Right Amount in the Right Place

When anesthesia is delivered too quickly it can pool up in your gums, causing discomfort even after the dental work is done and the anesthesia has worn off. The Wand© solves that by delivering the right amount at the optimal rate. It gets the anesthesia to the spot where it’s needed, without numbing a large part of your mouth. So if you’re having just one tooth worked on, The Wand© can even numb just that one tooth.

Takes the Pain Out of your Dentist Visit

The digital precision of The Wand© even allows us to work on several parts of your mouth during one visit if needed. Which could mean fewer visits back here for you. Once you leave this office, you can get on with your life right away. You won’t have the usual lingering numbness, tingling, or mouth-biting while the anesthesia is wearing off.

Intraoral Camera

Dr. Knollman utilizes intraoral camera technology that helps enhance your understanding of your diagnosis. 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!

Intraoral 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, a dental 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!

CEREC 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 administers an anesthetic and prepares your tooth for the restoration, removing decayed and weakened tooth structure. This preparation is just like he 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 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 10 – 20 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 teeth 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 10 to 20 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.
