'I've always been the guy where, if we're doing clinical dentistry and there is repetitive work, something we're doing over and over, I try and look to change it up without losing the needed accuracy,' said Les Kalman, Schulich School of Medicine and Dentistry professor. 'Dentistry is pretty market driven and a lot of what I?m doing is trying to make clinical dentistry better for the patient and the dentist.'
His latest idea, the Virtual Facebow app, is a digital companion for the diagnosis and treatment-planning phase of dentistry. Available in the Android market, the app also acts as an educational guide for dental students or patients undergoing treatment.
'When we see a patient for the first time, we need up-front data,' Kalman said. 'We're going to need models of your teeth. If you're just in for a check-up or cleaning there's no real need. But if you are doing a denture, a bridge or an implant, that's when we do the mold.'
A dental mold (or impression) is an imprint of your teeth used for everything from diagnosis and treatment planning to the creation of custom trays, dentures, crowns, or other prostheses and orthodontics. A proper mold will capture the teeth and surround structures of the oral cavity; it is the map to your mouth.
But molds are not 100% accurate-1 in 3 needs to be remade.
Kalman's app replaces the physical process with a digital one; creating, in his words, a more accurate reading for the patient and the dentist.
'Let's go digital where we can have safeguards built in,' he said. 'You can email the whole series to the lab, which would be great for them to verify what a dentist is requesting. We always want the best for the patients. This improves time, accuracy and reduces remakes by 5% to 10%. Think of the money saved.'
While it may not mean the complete elimination of moulds, Kalman said allowing dentists to do everything from establishing the lower jaw cast to the upper with an accurate bite, creating an aesthetic tooth guide prior to treatment and email entire data sets in common JPEG or PDF formats?all with a simple touch of their finger?is a huge step forward.
