Centric relation and programming semiadjustable articulators with the universal jig. Part I: Technique.
To obtain centric relation and program recordings, a universal jig was made to be molded after adjustment to the upper incisors by means of dental plaster. The jig can be produced by means of an autopolymerizing resin mold based on the wax model. Once the jig is in position, the patient is asked to produce left and right lateral movements until muscular relaxation is obtained. This allows centric relation to be recorded by whatever method use. After plaster has been injected on the occlusal surfaces of the teeth, the patient is asked to close his jaws on the jig and to perform either a propulsion movement or left- or right-lateral movement so as to obtain two plaster "bites" ready for the programming of semiajustable articulators.
