  • Myofascial Pain/Occlusion Precision occlusal splints and the diagnosis of occlusal problems in myogenous orofacial pain patients

    Glenn M. Kidder, DDS, FAGD
    Roger A. Solow, DDS
    2014 Mar/Apr; 62(2):24.   

    Research has shown that occlusal interferences affect masticatory muscle pain or dysfunction. Resolution of these problems with precise occlusal correction indicates that dental occlusion is a causative or contributory factor. However, some reports conclude that occlusion is unrelated to masticatory muscle pain or dysfunction. An explanation for this discrepancy in findings is that these nonconfirmatory studies had not documented any pretreatment or corrected occlusion. The rationale and requirements for proper occlusal splint fabrication with a verified therapeutic occlusion are presented.

  • Myofascial Pain/Occlusion Precision occlusal splints and the diagnosis of occlusal problems in myogenous orofacial pain patients

    Glenn M. Kidder, DDS, FAGD
    Roger A. Solow, DDS
    2014 Mar/Apr; 62(2):24.   

    Research has shown that occlusal interferences affect masticatory muscle pain or dysfunction. Resolution of these problems with precise occlusal correction indicates that dental occlusion is a causative or contributory factor. However, some reports conclude that occlusion is unrelated to masticatory muscle pain or dysfunction. An explanation for this discrepancy in findings is that these nonconfirmatory studies had not documented any pretreatment or corrected occlusion. The rationale and requirements for proper occlusal splint fabrication with a verified therapeutic occlusion are presented.

  • Myofascial Pain/Occlusion Precision occlusal splints and the diagnosis of occlusal problems in myogenous orofacial pain patients

    Glenn M. Kidder, DDS, FAGD

    2014 Mar/Apr; 62(2):24.   

    Research has shown that occlusal interferences affect masticatory muscle pain or dysfunction. Resolution of these problems with precise occlusal correction indicates that dental occlusion is a causative or contributory factor. However, some reports conclude that occlusion is unrelated to masticatory muscle pain or dysfunction. An explanation for this discrepancy in findings is that these nonconfirmatory studies had not documented any pretreatment or corrected occlusion. The rationale and requirements for proper occlusal splint fabrication with a verified therapeutic occlusion are presented.
