Why UK Dentists Are Turning to T-Scan for Occlusal Analysis — and How It's Transforming Patient Outcomes

When articulating paper alone only gets it right 12% of the time, leading clinicians are choosing digital. Here's what two of the UK's most respected dentists discovered when they adopted T-Scan in their practices.

"Articulating paper will only show contacts — but not the timing or the pressure of that contact. Studies show that dentists attempting to assess bite pressure using articulating paper alone got it right just 12% of the time."

That striking statistic comes from Dr. Jeremy Bliss of Bliss Dental — one of our T-Scan customers here at Clark Dental Sales — and it captures precisely why digital occlusal analysis is rapidly becoming the clinical standard of care for bite assessment in the UK.

In January 2026, Dr. Bliss joined Dr. Jaz Gulati on the Protrusive Dental Podcast (Episode PDP255) to discuss one of dentistry's most debated topics: can occlusal adjustment genuinely treat TMD? The conversation — watched and listened to by tens of thousands of dental professionals worldwide — centred on T-Scan technology and a treatment protocol called Disclusion Time Reduction (DTR).

Both Jeremy and Jaz are T-Scan users, and their clinical experiences offer a compelling case for any dental practice considering whether digital occlusal analysis is right for them.

Dr. Jeremy Bliss joins Dr. Jaz Gulati on the Protrusive Dental Podcast to discuss T-Scan and DTR therapy. Watch the full episode above.

What Is the T-Scan — and Why Does It Matter?

The T-Scan, developed by Tekscan, is dentistry's only clinically recognised and research-validated digital occlusal analysis system. Where traditional articulating paper leaves a static mark showing only where contact occurs, T-Scan reveals a dynamic picture of when and how much force is applied to each tooth — in real time, as the patient bites and moves their jaw.

The system uses a thin, flexible pressure sensor — held in a handle connected by USB to a computer — that the patient bites down on. The process takes no more than 15 seconds and is completely painless. The resulting data is displayed on screen as a colour-coded force map, showing bite force distribution across individual teeth, along with a timeline of contact sequence and magnitude. This can be reviewed as a 'movie' of the patient's bite, replayed and analysed frame by frame.

As Dr. Bliss explains, this level of diagnostic precision changes everything — particularly for patients presenting with unexplained tooth sensitivity, failing restorations, chronic headaches, jaw pain, or grinding habits. Without T-Scan data, many of these patients go undiagnosed for years, cycling through GPs, neurologists, and physiotherapists without ever addressing the root cause.

The Clinical Case: What T-Scan Reveals That the Eye Cannot See

One of the most powerful themes in Dr. Bliss and Dr. Gulati's podcast conversation is just how much clinical information is hidden from even the most experienced dentist without digital occlusal data.

When a patient bites on articulating paper, the marks show contact points — but they give no indication of which teeth are bearing the most load, in what order contacts are being made, or how long posterior teeth remain in contact during excursive movements. This last measurement — known as Disclusion Time — is, according to Dr. Bliss, at the heart of a wide range of occlusion-related problems.

"T-Scan provides objective data on tooth contact timing and force — data that is simply impossible to obtain with the eye or with articulating paper alone."

Key insight Protrusive Dental Podcast

In an ideal occlusion, the overbite created by the front teeth and canines guides the lower jaw so that the back teeth come apart quickly during side-to-side movements — a Disclusion Time of approximately 0.5 seconds or less. T-Scan can measure this precisely. Where Disclusion Time is prolonged, the posterior teeth remain in contact during excursions, placing sustained load on the temporalis and masseter muscles and, over time, contributing to the kind of chronic muscular overactivation that drives headaches, migraines, tooth wear, and TMD symptoms.

T-Scan's Role in Disclusion Time Reduction (DTR)

The treatment protocol at the centre of the podcast discussion is Disclusion Time Reduction (DTR) — a conservative, data-guided approach to occlusal adjustment developed by Dr. Robert Kerstein and now being adopted by a growing number of forward-thinking UK clinicians, including both Dr. Bliss and Dr. Gulati.

DTR uses T-Scan data — combined with EMG (electromyography) to simultaneously measure muscle activity — to identify and eliminate the posterior tooth contacts that are prolonging disclusion. The adjustments are minimal: typically less than 1mm of enamel removal, or in some cases the addition of composite to a worn canine, guided entirely by the T-Scan readout. The goal is to shift occlusal contact during excursive movements to the canines and anterior teeth, allowing the posterior muscles to relax.

Key T-Scan benefits highlighted in the podcast

Objective, quantified data — removes guesswork from bite assessment; gives dentist and patient a shared, visible record
Dynamic measurement — captures the sequence and timing of contacts throughout jaw movement, not just static bite marks
Treatment guidance — tells the clinician exactly which teeth to adjust and by how much, reducing over-adjustment risk
Patient education — the visual display helps patients understand their bite in a way that a verbal description never could
Before and after documentation — T-Scan captures pre- and post-treatment data, demonstrating measurable clinical change
Integration with EMG — when combined with electromyography, T-Scan provides a comprehensive picture of how the bite is affecting masticatory muscle activity

Which Patients Benefit Most from T-Scan Analysis?

According to the clinical experience shared by both Dr. Bliss and Dr. Gulati, T-Scan is valuable across a wide range of patient presentations — but it is particularly transformative for patients who have been struggling for years without a clear diagnosis.

Patients with unexplained chronic headaches or migraines — often referred by GPs after neurological investigations have drawn a blank
Bruxists and grinders — particularly those who have gone through multiple mouthguards with diminishing effect
Patients with recurrent restoration failures — cracked fillings, failed crowns, chipped veneers, or compromised implant restorations
Post-implant patients — T-Scan helps prevent early loading on implant restorations, protecting both the bone and the prosthetic work
Complex restorative cases — ensuring even force distribution across new crowns, bridges, or full-arch restorations before sign-off
Patients with TMD and jaw pain — where a muscular origin is suspected and conservative treatments have not resolved the problem

Importantly, as the podcast discussion makes clear, T-Scan is not only a tool for specialist practices. Its value in everyday restorative dentistry — checking occlusion after crown placement, for example — makes it a practical asset for any practice that takes occlusion seriously.

Two T-Scan Users, Two Clinical Perspectives

What makes the Protrusive Dental Podcast episode particularly compelling for UK dental professionals is that both guests bring a grounded, practice-based perspective to T-Scan — not a theoretical one. Both Jeremy and Jaz are T-Scan customers of ours at Clark Dental Sales, and their real-world experiences reflect exactly the kind of clinical transformation the technology is capable of delivering.

Host of the Protrusive Dental Podcast — one of the most listened-to dental education platforms in the world — Dr. Gulati underwent T-Scan and DTR training under Dr. Robert Kerstein in September 2025, with Dr. Bliss also involved in that training. He now offers DTR treatment at his Richmond, London practice, bringing digital occlusal analysis to a wider audience of both patients and dental peers.

The broader impact of the podcast episode should not be underestimated. With tens of thousands of listeners across the UK and internationally, PDP255 has significantly raised awareness of T-Scan and DTR among dental professionals who may previously have been unaware of either. For patients, it provides a clear, accessible explanation of why their headaches or jaw pain might have a dental origin — and what can be done about it.

T-Scan and the Evidence Base

One of the most important points made during the podcast discussion is that T-Scan and DTR are not fringe techniques. The technology is supported by a growing body of peer-reviewed research, including a systematic review examining the effectiveness of T-Scan in identifying occlusal interferences and its role in managing temporomandibular disorders. The review, published in the dental literature, concluded that T-Scan provides clinically meaningful data that supports more accurate occlusal diagnosis and treatment than traditional methods alone.

Tekscan describes the T-Scan as "dentistry's only clinically recognised and research-validated digital occlusal analysis system" — a distinction that matters to clinicians who need confidence that the tools they invest in are grounded in evidence, not just innovation.

"Don't buy advanced occlusal or motion-tracking tech unless your type of dentistry, training, lab support, and local backup can fully use the data — otherwise it's just a Ferrari stuck in traffic."
