From the combination of materials investigated in this study, the following scale of fidelity can be settled from best to worst result: Despite its favorable properties, ZOE is a brittle material that strongly interoccclusal to the dental surface due to contractions and, in the presence of excesses, it may suffer rupture and distortion and cause vertical displacement 9,17, Int J Prosthodont ;3: Br Dent J ; Special care was taken not to change the vertical dimension of occlusion at the moment of interoccusal recording.
Differential accuracy of elastomeric recording materials and associated weight change. A study of interocclusal record 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 Figure 6 shows that condensation silicone presented the greatest differences compared to the standards.
Five cast pairs upper and lower arches were obtained for each patient, in recorda a way that each tested combination of materials would be represented by a pair of casts with their own standard measurements for evaluation. In this study, the combination of acrylic resin and wax presented the lowest mean value of vertical separation between casts.
Braz Dent J ; An accurate interocclusal record by creating a vertical stop. Data were analyzed statistically by analysis of variance and Tukey’s test for individual comparisons.
Contemp Clin Dent ;9, Suppl S1: In a second stage, the records recordds interposed between the casts and fixed with wooden rods and compound, so that the measurements could be made. Various authors have described different tech- niques of making accurate Interocclusal records par- ticularly in situations when the distal most tooth is used as an abutment.

Bite registration, epidemiological study, interocclusal record, interocclusal wax, polyvinylsiloxane. Comparison of five interocclusal recording materials.
The use of wax as a interocclusal recording material has been debated because it reportedly lnterocclusal mandibular deflection, resistance to closure and distortions with changes in temperature 3,9,14, Maintenance of vertical dimension of occlusion was always checked by visualization of tripodism obtained by the anterior and posterior occlusal contacts.
There is a higher risk of distortion due to interference by the soft tissues of the margins, which can be compressed and may give origin to errors on cast mounting, if special attention is not taken during impression.
In all cases of prosthetic rehabilitation, accurate diagnosis, proper planning and correct execution of clinical and laboratory procedures are mandatory for high-quality results. Creating a vertical stop for interocclusal interocclusl.

Evaluation of the accuracy of interocclusal records in relation to two recording techniques. Five combinations of materials commonly used for intermaxillary records in cases of bilateral free end saddle were evaluated: The glossary of prosthodontic terms.
Rolls of 7 wax of uniform thickness were placed on the alveolar margin crest to create space for the alginate under the plate. In the absence of definitive occlusal contacts for direct relation of the casts, an interocclusal record is required. Int J Prosthodont ;2: How to cite this URL: When an adequate number of opposing teeth and stable intercuspation exist, direct occlusion of the casts is the most accurate method of articulation.

This becomes even more important when the distal tooth in the arch is also an abutment in the fixed partial denture.
