Some article shows that tooth contacting habit have a correlation with TMD. Most of them using a questionnaire to investigate the evidence. I would like to know, Is there any information about the duration of tooth contacting habit? The duration might be shorter than clenching/tonic.
I agree with Muhammad, TCH is a factor for TMD pain.

Abu-Hussein Muhammad and Haroon Rashid, Thank you for your very good answer and attached file.
I agree with you that TCH could evoke TMD symptoms. Even the role of this habit and TMD not clearly yet.
Future research regarding this topics would be necessary
Acing Habibie Mude, excellent question and the answer is yes! I will send you a link to look at some of the research done by Robert Kerstein on DTR. (Disclusion Time Reduction) Here the occlusion is altered to reduce the amount of time the teeth contact during excursions to below 0.50 seconds in excursion (right and left) movements. You will need to have a TekScan before you could ever measure it, and you would need TekScan to perform DTR and ultimately shorten the time. I will include a link that will show a few patients I have treated using this treatment and you can hear what they say. Also I included a link to my site where (with his permission) I have included all of his publications I could find. I am familiar with some published authors, and the behavioral approach to TMD. I have done around 50 DTR cases over the last year and I dont make bite splints, night guards, NTI, or any other acrylic to put between patients teeth for TMD. After having DTR done my patients deny sleeping or wearing the acrylic splints made before therapy was initiated. The bottom line is once disclusion time is reduced to below 0.50 seconds TMD patients start feeling better. Hope this helps. Regards.

Ben A Sutter, thank you very much for a great explanation, also for the attachments file. DTR methods looks like more simple than bite splint.
That is an interesting way to treat the unbalance-mastication force.
I would like to know, don't you make a some intervention directly to the muscles? or by reducing the occlusal contact alone is sufficient to alleviate the symptoms of TMD.
Once again, thank you for your valuable answer..
DTR is very fast! about 30% of the patients begin feeling relief on visit one BEFORE THEY LEAVE THE OFFICE! I do nothing to the muscles other than measure them. Many times you can see the exact correction that reduces muscle activity. I no longer build splints or night guards. I will make a fixed orthotic if I am making an increase in VDO. In my experience once the structural issue is corrected (the teeth) the functional (muscles) issues take care of themselves. Correcting an unbalanced bite does help, but timing trumps the balance of force issues almost every time.
Ben A Sutter, thank you very much for your explanation.
I highly appreciate your explanation.
