For decades, dental x-rays have helped us accurately diagnose and treat a wide array of dental diseases and conditions. But even with recent advances in digital imaging, the traditional x-ray does have one drawback: its two-dimensional view doesn’t always provide the “big picture” that a three-dimensional viewpoint can provide.
But a new type of x-ray technology can do just that: known as cone beam computed tomography (CBCT), these machines record hundreds of digital images as a cone-shaped beam of x-ray energy is projected through a device that rotates around a person’s head. A computer then assembles the images into a single three-dimensional image that can be manipulated on screen to view from various angles. Not only does this provide greater context and detail, it does so with no more radiation exposure than a standard 20-film digital full-mouth x-ray series.
While CBCT hasn’t replaced the traditional x-ray, it’s making its mark in a number of specialized areas of dentistry. The following are just a few of the ways CBCT is improving both accuracy and treatment outcomes.
Orthodontics. CBCT can provide a much more detailed view of the entire jaw; this can help us determine the best locations for realigning teeth safely and effectively.
Dental Implants. With a CBCT scan we can precisely locate nerve canals, sinuses and adjacent teeth before implant surgery to locate the best position for the implant.
TMD Treatment. To help develop the best treatment approach for alleviating the pain and dysfunction of temporo-mandibular joint disease (TMD), a CBCT scan can provide us detailed information on how the disease is affecting a patient’s joints, teeth, sinuses and airway.
Impactions. An impacted tooth can exert damaging pressure against the roots of neighboring teeth. A CBCT scan allows us to observe the impacted tooth from various vantage points to determine the best treatment approach for neighboring teeth, nerve canals and sinuses.

Daily fatigue or complaints of your snoring from family have led you to see your doctor about the problem. After an exam and a test session in a sleep lab, your problem now has a name — obstructive sleep apnea.
This common sleep-related breathing disorder (SRBD) occurs when the soft tissues in the back of the throat over-relax during sleep. The relaxed tissues obstruct air flow to the trachea (windpipe) and cause “apnea,” where you cease to breathe. The lack of oxygen causes you to wake, even for a micro-second, to begin breathing again. This may occur multiple times throughout the night, diminishing the quality of your sleep and leading not only to drowsiness and daily fatigue but also contribute to cardiovascular disease or other systemic conditions.
The most effective treatment for sleep apnea is the use of a Continuous Positive Airway Pressure (CPAP) machine while you sleep. The machine delivers pressurized air to a face mask you wear while you sleep; the additional pressure keeps the airway open. However, a CPAP machine does have a few disadvantages, including discomfort while attached to the machine, nasal congestion and dryness, or claustrophobia. These effects can be so pronounced for some patients, they’re unable to adjust themselves to the machine.
If you have mild to moderate sleep apnea, there may be an alternative — a custom-fitted oral appliance we manufacture for you to wear in your mouth while you sleep. The appliance pulls the lower jaw forward resulting in a wider opening of the airway. In addition to being less cumbersome than a CPAP mask, an oral appliance is easier to wear, compact in size for easy travel and doesn’t require electricity.
While an oral appliance is an effective alternative to a CPAP machine for many patients, it does have a few disadvantages including problems with saliva flow (too much or too little), muscle or teeth soreness and minor tooth or jaw movement. Still, an oral appliance might be the right solution to relieve your sleep apnea over the long-term.

With a 95-plus percent survival rate after ten years, dental implants are one of the most durable replacement restorations available. Implants can potentially last much longer than less expensive options, which could make them a less costly choice in the long run.
But although a rare occurrence, implants can and do fail—often in the first few months. And tobacco smokers in particular make up a sizeable portion of these failures.
The reasons stem from smoking’s effect on oral health. Inhaled smoke can actually burn the outer skin layers in the mouth and eventually damage the salivary glands, which can decrease saliva production. Among its functions, saliva provides enzymes to fight disease; it also protects tooth enamel from damaging acid attacks. A chronic “dry mouth,” on the other hand, increases the risk of disease.
The chemical nicotine in tobacco also causes problems because it constricts blood vessels in the mouth and skin. The resulting reduced blood flow inhibits the delivery of antibodies to diseased or wounded areas, and so dramatically slows the healing process. As a result, smokers can take longer than non-smokers to recover from diseases like tooth decay or periodontal (gum) disease, or heal after surgery.
Both the higher disease risk and slower healing can impact an implant’s ultimate success. Implant durability depends on the gradual integration between bone and the implant’s titanium metal post that naturally occurs after placement. But this crucial process can be stymied if an infection resistant to healing arises—a primary reason why smokers experience twice the number of implant failures as non-smokers.
So, what should you do if you’re a smoker and wish to consider implants?
First, for both your general and oral health, try to quit smoking before you undergo implant surgery. At the very least, stop smoking a week before implant surgery and for two weeks after to lower your infection risk. And you can further reduce your chances for failure by practicing diligent daily brushing and flossing and seeing your dentist regularly for cleanings and checkups.
It’s possible to have a successful experience with implants even if you do smoke. But kicking the habit will definitely improve your odds.
