Please use our dental library to learn more about dental problems and treatments available. If you have questions, please contact us.

Oral and maxillofacial surgeons are unique among dentists in that they all have completed an additional four years of hospital-based training alongside medical residents, and can administer all types of anesthesia. If you have a diseased or impacted tooth that needs to come out, implants to be placed, a suspicious lesion that needs a biopsy, or any other oral health condition requiring surgical diagnosis or treatment, we can help. Learn more about Oral Surgery.

Snoring & Sleep Apnea

Chronic loud snoring is a common symptom of Obstructive Sleep Apnea (OSA), which occurs when the upper airway is blocked to the point of causing significant airflow disruption, or even no airflow whatsoever for 10 seconds or more. This can be a dangerous situation. Learn more about Snoring & Sleep Apnea.

Tooth Extractions

There are times when it is in your best interest to have a tooth extracted (removed). This could be the case for a variety of reasons, including: damage or trauma to the tooth; an impacted wisdom tooth that may cause trouble for you later on; or overcrowding. Learn more about Tooth Extractions.

Implant Dentistry

Dental Implant Video

If you are missing one or more teeth, dental implants offer the comfort and security of a permanent replacement that looks and functions just like your natural teeth. Dental implants also help preserve the tooth-supporting bone in your jaw that deteriorates when even one tooth is lost.

Oral Diagnosis & Biopsies

When it comes to detecting certain oral or systemic (whole-body) diseases, a thorough dental exam may be your first line of defense. Learn more about Oral Diagnosis & Biopsies.

Bone Grafting

Bone grafting, a minor in-office surgical procedure, is commonly used in dentistry to correct deficiencies in bone quality and to build support for teeth or dental implants. Learn more about Bone Grafting.

Sedation Dentistry & Anesthesia

We want you to have the most comfortable dental treatment experience possible. That's why we offer sedation, to help you relax, and/or anesthesia, to block your sensations of pain. Learn more about Sedation Dentistry.

Facial Trauma & Reconstructive Surgery

Oral and maxillofacial surgeons are capable of treating the full scope of injuries to the structures of the face, mouth or jaws — including the teeth, the bones of the jaws and face, and the tissue of the skin and gums. We can also treat congenital defects such as cleft palate.

TMJ Disorders

If you have chronic pain in or around your jaw, or find the movement of your jaw is restricted, you may be suffering from a temporomandibular joint (TMJ) disorder. Learn more about TMJ Disorders.

Treating Dental Emergencies

We can treat a variety of traumatic dental injuries, including teeth that have been moved or knocked out entirely. Please call our office for assistance, or click here to learn more about what to do in a dental emergency.

Cone beam dental scans.In the early 20th Century, not long after X-rays were discovered, medical professionals recognized their value as diagnostic tools: They could clearly reveal structures hidden inside the body without the need for risky surgery. At the dawn of the 21st century, a revolutionary new technology has entered the diagnostic arena. Today, Cone Beam Computed Tomography (CBCT) promises to change the way many dental problems are diagnosed and treated.

Cone Beam CT has some similarities with conventional X-rays, and also with the standard CT scans you would get in a hospital setting. But it's a quantum leap forward in technology and diagnostic precision. For the dentist, it offers the ability to visualize intricate structures inside the mouth, such as root canals, nerves and sinuses (air-filled spaces) in the jaw — in three dimensions — without surgery. For the patient, it can reduce the need for invasive procedures, shorten treatment time and offer the chance for a better outcome.

The detailed diagnostic images that CBCT provides have made it an essential tool in many dental specialties. But, as with any diagnostic tool that uses radiation, the medical benefits offered must be weighed against the (small) potential risks of the procedure.

How Cone Beam CT Works

X-rays, like visible light, are a form of energy on the electromagnetic spectrum. Just as light makes an image on photographic film (or a digital camera sensor), X-rays can also form an image. The difference is that energetic X-rays can penetrate bone and soft tissue, and reveal its hidden structure by their varying degrees of absorption; in other words, they form a grayscale picture of what's underneath the surface. But conventional X-rays are limited: Like a still-life picture, they show only one perspective on the scene.

Now imagine a “flip book” — the kind of small book made up of a series of pictures, each slightly different. When you rapidly page through it, you may see (for example) an animated cartoon or a still subject from different perspectives. If you could put together a flip book made from a series of X-ray “slices” of the same subject, taken at slightly different angles, you would be able to create an “animation” of the X-rays. And from there, it's only one more step to making a 3-D model.

That's exactly what CBCT scanners do. Using a rotating imaging device that moves around the patient's head, the scanner records between 150 and 600 different X-ray views in under a minute. Then, a powerful computer processes the information and creates a virtual model of the area under study. When it's done, the model appears as a three-dimensional image on a computer screen: It can be rotated from side to side or up and down, examined in greater or less detail, and manipulated in any number of ways — all without the patient feeling any discomfort... or even being present.

Where Cone Beam CT Is Used

The ability to see fine anatomical structures in 3-D has proven invaluable in treating conditions in many areas of dentistry.

  • Orthodontics: Having accurate information on the position of teeth and jaws helps determine exactly how and where teeth should be moved.
  • Dental implants: Detailed CBCT images are used to determine the optimum location for the titanium implants while avoiding nerves, sinuses and areas of low bone density.
  • Orthognathic Jaw Surgery and Temporo-mandibular Joint (TMJ) Disease: Patients benefit when the specialists who treat these conditions can evaluate their anatomy with the three-dimensional perspective that cone beam CT provides.
  • Oral Surgery: Treatment for tumors or impacted teeth is aided by the level of fine detail shown in these scans.
  • Endodontics: Dentists performing intricate procedures (like complex root canals, for example) can benefit from a clearer visualization of the tooth's anatomy.
  • Sleep Apnea: Imaging the tissues and structures of the nose, mouth and throat can aid in diagnosis and treatment of this dangerous condition.

Could Cone Beam CT Benefit You?

Each patient's situation is different, and must be carefully considered by a clinical professional before any test or procedure is performed. While CBCT delivers a smaller dose of radiation (X-rays) than many other diagnostic tests, it still carries a small risk — particularly for younger patients, or those with other health problems. As is the case for any medical procedure, all risks, benefits and alternatives are taken into account before the procedure is recommended.

Getting The Full Picture With Cone Beam Dental Scans Dental imaging took a major leap forward at the beginning of the new millennium with a three-dimensional technology known as cone beam computed tomography (CBCT). The name comes from the cone-shaped beam of x-rays the CBCT machine projects as it rotates around a person's head, taking multiple images that are compiled into a 3-D picture by a computer.
