Centric relation
Maxillo-mandibular relationship, independent of tooth contact, in which the condyles articulate in the anterior-superior position against the posterior slopes of the articular eminences. JPT9
This paper studied at the different in what investigators report on an assessment of four techniques used to establish centric relation in dentate individuals.
The techniques analyzed were:
1- Swallowing or free closure
Coined by Shanahan
2- Chin point guidance
Coined by McCollum
3- Chin point guidance with anterior jig
Coined by Lucia
4- Bilateral manipulation
Coined by Dawson/Pankey, Mann, Schuyler (PMS)
Results:
Assessment done to evaluate deviation from center of cluster of dots (deviation from the median point)
- Bilateral manipulation (0.05 mm)
- Chin point guidance with anterior jig (0.07 mm)
- Chin point guidance (0.14 mm).
- Swallowing (0.40 mm)
