Answers on Anterior Guidance

We're going to answer some questions regarding the webinar that I did the other night on anterior guidance, and we have some very good questions.

What about group function? Is it only for dentures?

The answer to this is that group function is routinely, very applicable to dentures, but not typically for natural teeth, with the exception of patients who do not have an anterior guidance. If they don't have an anterior guidance to disclude the balancing side in excursions, then we have to use the working side in group function to disclude the balancing side. As long as we have an anterior guidance though, we do not want group function. We want just lines in front, dots in back with the anterior guidance separating all the posterior teeth in all excursions.

Is Anterior Guidance a Myth?

In this webinar, Dr. Dawson discusses in depth the often discussed and debated concepts of Anterior Guidance. This discussion includes understanding how the envelope of function, incisal edge position, and lingual contours work in harmony with the anatomy of the TMJ and muscles of mastication, which are concepts that must be mastered by the restorative dentist.

Hear him revisit timeless principles that he has spent a career and lifetime in understanding and teaching to our profession.

Time-Tested Process for Observing Symptoms of Occluso Muscle Disorder

In this blog article, Dr. Peter Dawson responds to a comment made on a previous article. The following was the comment:

It has been demonstrated repeatedly since 1997 that the relationship of bruxism to chronic craniofacial pain is non-linear. [1-4] In fact, 20% of the Raphael, et al, pain sample showed no bruxism. Lavigne lists among his finest work the discovery that sleep bruxism begins from an open mouth position with the action of the depressors. [5] This is not an “occlusal” problem beyond tooth wear, should the patient so decide. 

That being said, the nature of the pain is such, particularly as it relates to headache, that keeping the posterior teeth apart with an appliance can prevent headache. As Mahan and Alling pointed out in their text [6], we have known that since 1960. [7] 

Sessle, Dubner and colleagues have shown repeatedly that the pain of chronic M/TMD is not inflammatory. [8] Masticatory muscles are fatigue resistant over time, [9, 10] and the excess substance found is glutamate, not hydrogen ions from lactic acid in chronic craniofacial muscle pain. [11]
