Clinical study of location and reproducibility of three mandibular positions in relation to body posture and muscle function

Regulation of Mandibular Postures: Mechanisms and Clinical Implications

“…A short account will be given of the basic concepts relevant to the present discussion. The fact that the centric relation can be determined with precision has been demonstrated with several different recording methods (Tripodakis et al, 1995). The precision does not vary with the amount of pressure applied to the chin, although a more posterior mandibular position is reached if more pressure is applied (Ingervall et al, 1971).…”

Reproducibility of Centric Relation Techniques by means of Condyle Position Analysis

“…Besides, different inclusion criteria are applied and different statistical analyses are performed. The studies (9,19,21,(23)(24)(25)(26)(27)(28) in which only one CR registration technique was used (bimanual manipulation, Gothic arch tracing, chin point guidance, push-back technique, neuromuscular centric technique, Roth's technique and others) using different methodologies (not only mandible position indicator, but also axiography, Arcus digma diagnostics, radiographic techniques (computerized tomography, magnetic resonance)) mostly concluded that all the techniques were reproducible and reliable in both symptomatic and asymptomatic examinees. In the scientific literature, there are also studies (29)(30)(31) that examined the consistency of two or more CR recording techniques.…”

“…Studije u kojima se testirala samo jedna tehnika (npr. bimanualna manipulacija, tehnika gotskog luka, vođenje bradom, push-back tehnika, neuromišićni centrik, Rothova metoda i druge) određivanja CR-a različitim metodologijama (ne samo indikatorom pomaka mandibule, nego aksiografijom, uređajem Arcus digma, radiografskim tehnikama (kompjutorizirana tomografija, magnetska rezonancija) uglavnom pokazuju da su tehnike bile ponovljive i pouzdane kod simptomatskih i asimptomatskih ispitanika (9,19,21,(23)(24)(25)(26)(27)(28). Ipak, prevladavaju studije u kojima se provjeravala konzistentnost dviju ili triju metoda određivanja CR-a.…”

Occlusion and posture: facts and beliefs

“…-changes in the position of the mandible influence body posture 81 ; -reciprocally, body posture seems to have an affect on the position of the mandible 81 , with the exception of centric relation and occlusion with maximum inter-cuspation, the localization and reproducibility of both of which are not affected 22,98 ; -habitual mandibular position, or rest position, is tied to cephalic posture 103 ;…”
