The concept of the sagittal condylar guidance: biological fact or fallacy?

Abstract

The clinical concept of a sagittal condylar guidance pertaining to the human temporomandibular joint is discussed in the light of selected studies on the anatomy, radiography and cineradiography of this joint, and clinical attempts at recording a sagittal condylar guidance. It seems as if there is no single and well defined sagittal condylar guidance in vivo, and thus no single and well defined sagittal condylar guidance angle applicable to the adjustable articulator.
