A Clinical Evaluation of Materials for Interocclusal Registration in Centric Relation The following conditions for the record of posterior section were tested . The initial resistance of interocclusal recording materials to closure changed from N to N, and a rapid rise in the working time was seen in all elastomers. Statement of Problem: Interocclusal recording materials should have good dimensional stability for precise articulation. Purpose:The aim of this in vitro study.

Com base nos achados deste estudo, a seguinte escala de reprodutibilidade pode ser estabelecida, do melhor para o pior: A clinical evaluation of materials for interocclusal registration in centric relation. The samples were measured using an optical microscope with a micrometer provision. After the material jelled, the records were removed Fig. Occlusal registrations using alginate irreversible hydrocolloid impression material. A comparison of two methods for locating the intercuspal position ICP whilst mounting casts on an articulator.
Comparison of five interocclusal recording materials.
Five cast pairs upper and lower arches were obtained for each patient, in such a way that each tested combination of materials would decording represented by a pair of casts with their own standard measurements for evaluation.

In all cases of prosthetic rehabilitation, accurate diagnosis, proper planning and correct execution interocc,usal clinical and laboratory procedures are mandatory for high-quality results. Interocclusal recording materials should have good dimensional stability for precise articulation.
The distances between corresponding interarch markers were measured and compared with the measurements taken on the physical typodont gold standard. On the other hand, when large edentulous spaces are recordign, specifically in posterior free end cases, cast mounting is considerably more complex 7. The measurements obtained by manual articulation of the casts were used as the standards to which the measurements obtained with the recording materials were compared.
Warren K, Capp N. Differential accuracy of elastomeric recording materials and associated weight change. Accepted September 21, These parameters are usually fulfilled by interocclksal registration bases fitted into wide edentulous spaces or free ends. A method of recording the interocclusal relationship of the teeth.
Properties of interocclusal registration material. For the records made with condensation silicone, the material was divided into materias equal parts placed in the right and left edentulous regions of the lower arch and the patients were instructed to occlude normally in maximum intercuspation Fig.

interoccclusal J Am Dent Assoc ; None, Conflict of Interest: An Experimental study of vertical deviations induced by different interocclusal recording materials. When maximum intercuspation is considered, in cases in which the number of teeth present is satisfactory and will provide cast stability, the casts can be mounted by manual articulation One method of articulating digital models is to use a digitized interocclusal record.
The materials were evaluated by measuring the vertical distance between pairs of reference points located on the bases of the upper and lower articulated casts.
As an inclusion criterion, only individuals who had some teeth remaining in the mandibular arch up to premolars were selected, in order to allow manual articulation of the casts by the presence of tripod support and horizontal stability. Ingerocclusal on the findings of this study, the following scale of fidelity can be settled from best to worst: Services on Demand Journal.
Special care was taken not to change the vertical dimension of occlusion at the moment of interoccusal recording. Int J Prosthodont ; Accuracy and dimensional stability of four interocclusal recording materials.
Comparison of five interocclusal recording materials.
Maintenance of vertical dimension of occlusion was always checked by visualization of tripodism obtained by the anterior and posterior occlusal contacts. The recording base should provide adequate fitting as well as rigidity and stability. In this study, the horizontal and vertical stability of the casts allowed their manual articulation in maximum intercuspation 1,3,4,6providing measurements that represented the standards for comparison to the different types of records evaluated.

The success of any prosthetic rehabilitating treatment depends on several aspects related to the precise mounting of casts in the articulator. Condensation silicone is extensively used for interocclusal records Motion View Software was used to articulate the digital models by matching points from the models to the digitized interocclusal records.
I Group A 1 h Polyvinyl siloxane is a more accurate interocclusal recording material when articulating digital models according to the process described in this study.
Perforations were made in the resin with a 5 spherical bur to retain the material Fig. Related articles Bite registration material dimensional stability interocclusal records.
