Our Technology

Dr. Andrew Cobb is committed to providing comprehensive dental care and treatments that are comfortable, effective and affordable. Dr. Andrew Cobb utilizes the concept of Minimally Invasive Dentistry by incorporating state-of-the-art technologies in his Washington, DC dental office, allowing him to detect problems in early stages and treat them with extreme precision.

Digital and Cosmetic Imaging

Dr. Cobb utilizes the concept of Minimally Invasive Dentistry by incorporating state-of-the-art dental technologies in his practice to ensure the highest level of patient care. Dental imaging is a groundbreaking addition to the world of dentistry. It allows a dentist to more accurately diagnose and treat dental conditions, ensuring the patients walks out with a healthier, brighter smile. Dental digital imaging allows Dr. Cobb to analyze, diagnose, treat dental conditions with a high level of accuracy. Dr. Cobb incorporates dental imaging into several aspects of his practice with the use of digital photography and digital radiography.

Benefits of Digital Photography and Radiology

When Digital Photography is combined with cosmetic dental imaging software, Dr. Cobb is able to simulate the results of the chosen procedure. Depending on the results, Dr. Cobb is able to diagnose, develop a plan, and treat a patient’s dental issues. Dr. Cobb is able to communicate the details of the procedure and the results with patients through digital photography.

Another valuable aspect of modern technology is Digital Radiographs. Digital Radiographs are a form of x-ray imaging, this technology surpasses the conventional use of x-ray films which are subject to deterioration over time. Digital radiographs subject the patient to lower levels of radiation. Due to their digital format, digital radiograph images can be easily manipulated, duplicated and shared with medical specialists.

Other benefits of Digital Photography and Radiography include:

  • Able to accurately detect small areas of tooth decay, periodontal disease, and even tumors
  • Results can be quickly and easily viewed
  • Makes storing and filing patients records easier
  • Can easily be to other dentist and specialist

Digital Dental X-Rays

Dr. Cobb uses digital dental x-rays to capture precise images of the teeth, bones, and joints. Dental x-rays are a very important tool that Dr. Cobb uses to diagnose a patient’s dental condition. In addition, dental x-rays can help Dr. Cobb identify hidden problems such as oral cancer, gum disease and TMJ disorders. Routine dental x-rays allows Dr. Cobb to monitor a patient’s health over time. He looks for structural changes in your teeth, and analyzes your bite for underlying jaw problems.

Digital x-rays are the gold standard in modern dentistry. Compared to traditional dental x-rays, digital x-rays are significantly faster and more comfortable. Digital dental x-rays are eco-friendly, because they don’t require chemicals to develop or space to store. The digital images can be kept in the patient’s digital dental records without concern for quality loss over time. The digital format can also be easily shared with other medical professionals when needed.

Intra Oral Photography

The IntraOral Camera is one of the leading technologies in modern dentistry. A tiny video camera on a wand-like probe moves comfortably inside the mouth around the teeth and gums. This allows us to easily, and accurately, identify issues.

The images captured from the IntraOral Camera are magnified and displayed instantly on a computer screen. Both the dentist and patient can see the images, allowing an open discussion about the issues and best ways to treat them. With the IntraOral Camera, it is easy to recognize potential problems in very early stages that might be missed during a traditional visual examination.

As with the digital dental x-rays, a patient’s progress can easily be tracked and recorded using the IntraOral Camera. Before and after pictures can be easily taken and stored in the patient’s digital health record.

Digital Impressions

Digital impressions are an innovative new technology in modern dental practices. Our digital impression technology uses lasers and optical scanning to digitally capture the surface and contours of the tooth and gums. The entire process takes less than five minutes, the time needed for conventional dental impression material to set.

Patients prefer digital impressions to conventional trays which are awkward and uncomfortable. Our system captures impressions with extreme precision and then immediately transmits them to a computer screen so that they can be analyzed by Dr. Cobb. Using sophisticated computer software, Dr. Cobb can view the impressions in 3-dimensions and show them to the patient for the highest level of communication.

Dr. Cobb is one of a handful of skilled dentists in the country using the Lava™ Chair-side Oral Scanner (COS), the latest technology in digital impressions. Traditional methods require patients to place uncomfortable trays in their mouth while the impression putty sets. Lava™ Chairside Oral Scanner (COS) allows patients to sit comfortably while getting their teeth and gums examined. Lava COS uses 3D video to capture live images of your teeth and gums, creating a digital impression without any added steps. Using the Lava COS is effective when creating dental impressions for patients who need dental crowns, dental bridges, and veneers.

About the size of an electric toothbrush, the Lava™ COS is a wand designed to glide comfortably over your teeth while taking continuous 3-D video images which can be reviewed instantly. With the Lava™ COS, Dr. Cobb can make precise, digital impressions of your teeth allowing for a quicker, more comfortable and interactive process for restoring your smile.

Benefits of Digital Impressions:

  • Shorter dental visit
  • More comfortable for patients
  • Better quality dental impressions
  • More accurate dental impressions
  • Can be electronically stored and sent

Most patients find that digital impressions are more comfortable than traditional impressions. Dr.Cobb strives to provide state of the art technology for patients to have the best experience possible while receiving their dental treatments.


Tek Scan

Technological advances in dentistry take much of the guesswork out of traditional analysis methods. Conventional methods for evaluating a patient’s bite require the use of articulating paper which can only show the end results of occlusal contact. Unable to record which contacts hit first or measure their relative strength, these methods can not produce a comprehensive assessment.

Dr. Andrew Cobb, DDS uses the T-Scan® III, a computerized occlusal (bite) analysis system. The handheld device allows him to quickly and accurately determine how well balance your bite is. You simply bite down on an ultra-thin sensor, which measures the time and force of your bite. The information is sent to the computer which analyzes and displays the data in minutes. From this 3-D analysis, Dr. Cobb can determine what is and what is not working with your bite.

An unstable bite can be painful and cause teeth and dental restorations to crack or break, and lead to gum disease, tooth loss or TMJ disorders. With hi-tech analysis, Dr. Cobb can provide you with timely and comprehensive solutions.

Joint Vibration Analysis (JVA)

What is Joint Vibration Analysis?

Joint Vibration Analysis (JVA) is among the latest technologies used in the analysis of TMJ function. This non-invasive tool records accurate and repeatable measurements in seconds and produces instant data for Dr. Cobb to interpret.

The human joints have surfaces that rub together; smooth, well-lubricated surfaces create little friction and as a result, little vibration. In some cases, these joints can be rough, due to age, damage or other causes. These rough surfaces produce increased friction and vibration. Depending on the type of disorder, certain kinds of disorders can create different wave patterns or signatures that can be interpreted by skilled professionals.

TMJ and Joint Vibration Analysis

Dr. Cobb has invested in the JVA technology to help him quickly and accurately identify TMJ disorders.JVA allows Dr. Cobb to precisely measure the vibrations in a patient’s Temporomandibular joints. The painless process uses tiny electrodes strategically placed around the jaw area which record any friction occurring in the bite. Friction indicates that there are uneven or rough surfaces or that the bite is not aligned properly, all of which lead to the often painful symptoms of TMJ disorders.

After analyzing a patient’s joint vibrations, Dr. Cobb is able to make an accurate diagnosis of TMJ and develop a personalized treatment plan designed to address the underlying bite concerns for long term oral health and improved function.

Dr. Cobb stays up to date with advancements in technology by continuously studying disorders like occlusion and TMJ dentistry. Combined with his expertise in the field of modern dentistry, Dr. Cobb provides each patient with comprehensive dental care that results in long lasting, beautiful smiles.
