Dr Robert Kerstein has been honored for his 29 year committment to measuring occlusal problems in TMJ/TMD patients with the T-Scan III technology, by being featured on the cover of this month’s Journal of Craniomandibular Practice.
Also included in this month’s issue is a TMD 45 patiemt treatment study that Dr. Kerstein and Mr. John Radke of Bioresearch Associates, completed in 2011. The study illustrates that the TMD treatment known as “Disclusion Time Reduction” produces verey signifucant muscle relaxation if the Disclusion Time Reduction is PROPERLY PERFORMED. This is a crucial aspect to the treatment effectiveness. Unless a TMD clinician learns how to perform a precision Disclusion Time Reduction, they will not obtain the desired physiologic muscle relaxation. This TMD occlusal treatment procedure requires measurement of the TMD patients functional occlusal movements with the T-Scan III Computrerized Occlusal Analksis System, combined with the BioPAK Electromyography System, to properly pefrform this very precise occlusal TMD treatment
A lack of occlusal treatment success has been noted in the TMD literature because most occlusal treatrments are unmeasured and rely on the clinician to interpret articulating paper markings, which offer the clinician no occlusal force, or contact timing information. They are just ink smears on teeth that result in hit-or-miss occlusal treatment.
This lack of occlusal treatment effect has actually held back progress in the treatment of TMD. Unmeasured, articulating paper only-based (non T-Scan/EMG based) occlusal treatment has NEVER BEEN SHOWN in any study to match the treatment effect of a properly performed and measured Disclusion Time Reduction.
The EMG data below shows the T-Scan based treatment effect: The Pre Treatment EMG (left pane) shows hyperactivity after “C” while the Post Treatment EMG (right pane) shows markedly less hyperactivity after “C”.
This physilogic improvemenmt to the muscles is what a properly performed Disclusion Time Reduction changes in the suffering TMD patient. Here is the abstract of Dr Kerstein’s published study in Cranio, that details this physiologic treatment effect.
