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.

One method of articulating digital models is to use a digitized interocclusal record. Clinical evaluation of the accuracy of interocclusal recording materials.

Interocclusal recording materials should have good dimensional stability for precise articulation. An experimental study of vertical deviations induced by different interocclusal recording materials. J Prosthet Dent ; Reording, Conflict of Interest: Notwithstanding the criticisms, this is still the most often used material in daily clinical practice because of its ease of handling, clinical versatility and low cost 3, In this study, the combination of acrylic resin and wax presented the lowest mean value of vertical separation between casts.

Clinical evaluation of interocclusal recording materials in bilateral free end cases

However, the accuracy of different interocclusal record materials to articulate digital models has yet to be evaluated. Five self-polymerized acrylic resin plates were prepared to obtain interocclusal records with irreversible hydrocolloid. Occlusal registrations using alginate irreversible hydrocolloid impression material. Accuracy and dimensional stability of four materisls recording materials.

Comparison of five interocclusal recording materials.

Determination of the accuracy of wax interocclusal registration. J Oral Rehabil ; Advanced Search Users Online: Moreover, successful treatment is highly dependent on precise mounting of the casts in the articulator.

The samples were measured using an magerials microscope with a micrometer provision.

Int J Prosthodont ;3: How to intedocclusal this article. Using a bite registration to articulate digital models should be considered the first step in the articulation process, with a likely residual need to manipulate the models manually.

The distances between corresponding interarch markers were measured and compared with the measurements taken on the physical typodont gold standard. Sitemap What’s New Feedback Disclaimer. The materials were evaluated by measuring the vertical distance between pairs of reference matedials located on the bases of the upper and lower articulated casts.

Dental Materials, Properties and Manipulation. Five cast pairs upper and lower arches were obtained for each patient, in such a way that each tested combination of materials would be represented by a inteorcclusal of casts with their own standard measurements for evaluation.

Comparison of five interocclusal recording materials.

After setting of the material, the records were removed and stored in sealed plastic bags with no humidity until reading 9. Duralay acrylic resin is a material with great dimensional stability, rigidity, precision in the reproduction of details, ease of handling and favorable degree of hardness during the setting process, which does not offer resistance to mandibular closure 13, All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.
