K7 Evaluation System

K7 Evaluation System

To improve treatment for patients with Temporomandibular Disorders (TMD), Crabapple Dental has invested in a K7 Evaluation System from Myotronics. This cutting edge technology provides us with a non-invasive means for measuring and recording mandibular function and masticatory muscle status (jaw tracking). This important information aids our clinicians in the diagnostic process and is vital in the treatment of TMD and migraine headaches. Dr. Sarah Roberts and the team at Crabapple Dental are pleased to provide this advanced technology to the residents of Alpharetta and the surrounding areas.

Dr. Sarah Roberts uses the K7 jaw tracking device from Myotronics to make custom orthotics for patients with TMJ/TMD or for any big cases that require bite changes. Ninety-percent of the pain that people feel from their head, neck and jaw is from muscle pain. If the muscles are in a relaxed position, the pain will naturally decrease. Custom orthotics made using the K7 Evaluation System provide an effective option for treating migraine headaches that does not involve medication. For patients who suffer from frequent migraine headaches, this new technology can be life-changing.


If you come into Crabapple Dental for a TMD evaluation, you will be put on the Myotronics K7 Electromyography Unit. The K7 allows us to record and analyze the activity of the prominent face, head and neck muscles attached to the lower jaw. We will measure the muscle activity as you perform different movements with your jaw, head and neck. Using this information, we can then diagnose your bite problem and prescribe the appropriate treatment or treatments to relax your jaw muscles and eliminate your painful symptoms.

If you are suffering from bite problems, TMJ/TMD or migraine headaches, please contact our Alpharetta Jaw Pain Treatment Specialist to schedule an appointment with Dr. Sarah Roberts today. We look forward to restoring your dental health.

I've been going to Dr. Roberts for a couple of years now (after a long period of not going to any dentist), and she has helped to bring my quickly developing periodontal disease under control. The staff is always professional and friendly there and they constantly use the most up to date technology. Great dentist! Aaron A.
Dr Roberts and her staff always go the extra mile for their clients. I can't say it's ever really fun to go to the dentist, but she's outstanding and really cares about helping you have a heathy mouth, not just pretty teeth. Jeremy R.
Dr. Sarah Roberts and her team (all of them) have given me the best experience I have had with a dental office. I have moved around a bit and out of the 4 offices I have gone to in the last 15 years, this is by far the best. I highly recommend. Ryan D.
