The introduction of different interocclusal recording materials has put clinicians in dilemma that which material should be used in routine clinical practice for precise recording and transferring of accurate existing occlusal records for articulation of patient’s diagnostic or working casts in the fabrication of good satisfactory prosthesis. RESULTS: Vinyl polysiloxanes reinforced by a stabilization tray were the most accurate materials able to reproduce a settled interocclusal position. These materials should have a good dimensional stability to achieve proper articulation. Interocclusal records were made with 5 experimental materials and then digitized.

The thermoplastic and wax materials were heated in a water bath according to the manufacturers’ instructions (Byte Right, 77°C; Aluwax, 40°C; Beauty Pink wax, 50°C). Most interarch measurements differed significantly from the gold standard measurements regardless of the material used to articulate the digital models ( Table I ). Study models and facial photographs are also keys to extraction decisions. A 500-g weight was placed on top of the articulator while the material set to prevent any expansion during setting from changing the occlusion. Digital models can also be used to superimpose pretreatment and posttreatment models to evaluate therapeutic outcomes. The digitized bite registrations were then used to articulate the maxillary and mandibular digital models using the software to identify the teeth on both the models and the bite registrations. 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. 19. DOI: 10.1055/S-0040-1703593 Corpus ID: 51747132. Interocclusal recording materials should have … An investigation of casts assembled by the use of seven interocclusal record materials and manipulated by three operators disclosed that: 1. The PVS materials were expressed onto the occlusal surfaces of the mandibular teeth, and the articulator was closed with manual pressure until the teeth were contacting in maximum intercuspation. Introduction The interocclusal registration material records the occlusal relationship between the natural and / or artificial teeth for planning occlusal rehabilitation and for construction of removable and fixed partial dentures.
