Occlusograms are Lying To Us! Don’t Trust the ‘Heat Map’ – PDP247

Ever had a patient swear their bite feels “off” - even though the articulating paper marks look perfect and you’ve adjusted everything twice over? Or maybe you’ve placed a beautiful quadrant of onlays, only to have them return saying, “these three teeth still feel proud.” If that sounds familiar, you’re not alone. In this episode, I’m joined (in my car, no less!) by Dr. Robert Kerstein, who was back in the UK to teach about digital occlusion and the power of the T-Scan and ‘disclusion time reduction therapy’. We dig into why a patient’s bite can still feel “off” even when everything looks right, how timing is just as important as force, and why splints and Botox don’t always solve TMD. Robert explains why micro-occlusion is the real game-changer, how scanners could mislead you, and why dentistry still clings to articulating paper. So if you’ve ever wondered why “perfect” cases still come back with bite complaints, or whether timing data can actually prevent fractures and headaches, this episode will give you plenty to chew on - pun intended. https://youtu.be/0lCAsjFhsXI Watch PDP247 on YouTube Need to Read it? Check out the Full Episode Transcript below! Key Takeaways: Micro-occlusion, not just “dots and lines,” is the real driver of patient comfort and long-term tooth health. T-Scan measures both force and timing, which scanners and articulating paper cannot capture. Many patients show signs of occlusal damage without symptoms. Disclusion Time Reduction (DTR) treats TMD neurologically without splints, Botox, or TENS. Relying on occlusograms alone for guiding reduction is risky. Dentists can reduce post-treatment complaints by balancing micro-occlusion with T-Scan. Adopting T-Scan requires proper training. CR can be a convenient reference point, but MIP works well in most cases if micro-occlusion is managed. Objective, repeatable data builds patient trust and provides medico-legal reassurance.

This episode meets GDC Outcomes A, C. AGD Subject Code: 250 – Clinical Dentistry (Occlusion/Restorative) Aim: to explore the role of micro-occlusion and timing in TMD and restorative success, highlighting how tools like T-Scan provide data that other tools cannot. This episode seeks to give dentists practical insights into diagnosing, preventing, and treating occlusal problems with greater accuracy. Dentists will be able to: Describe the role of micro-occlusion and disclusion time in TMD symptoms and tooth wear. Recognising the limitations of traditional methods of occlusion adjustment. Understand how objective occlusion data supports comfort, longevity of restorations, and preventive care. Click below for full episode transcript: Teaser: Pressure is a force over surface area. And when it gives us the red, the blue, yellow, it's not measuring the force, so it cannot tell us the pressure. So tell us about what the nuances of being careful with the occlusogram and where it fails in the face of something more sophisticated, like the T-scan. The essence of a scanning technology is that all the teeth are scanned with the patient's teeth apart. No one's biting. There's no forces captured. There's no contacts. There's no gathering of teeth banging together or rubbing around. So it completely is falsely representing. These colour coded occlusograms have no force information in them at all. Anyone who's used articulating paper, which most of us do, and the T-scan, you still mark the teeth with paper, but you choose the contacts to treat based on the data, not based on where the paper marks look. And very often, the most pressure points of contacts are small, scratchy little marks ...
