Comparison of 5 types of interocclusal recording materials on the accuracy of articulation of digital models

An In Vitro Study of Condylar Displacement Caused by Interocclusal Records: Influence of Recording Material, Storage Time, and Recording Technique

“…The condylar displacements caused by VPS and polyether were statistically significantly lower than that of aluminum wax or of hydrocarbon wax compound. This is in agreement with other studies, which reported that elastomeric materials showed a higher dimensional stability and a higher resistance to deformation than waxes. Also the inaccuracy of waxes may be explained by their thermal dimensional behavior under heating and cooling conditions…”

Accuracy of a smartphone-based orthodontic treatment–monitoring application: A pilot study

“…The equivalence bounds of 60.5 mm were chosen because, according to the cast-grading system of the American Board of Orthodontics, a discrepancy of this magnitude is not considered to be clinically relevant. 16 However, the distances for overbite and overjet, for example, are far shorter than the cross-arch measurements used in the current study, so using equivalence bounds of 60.5 mm may be stringent beyond what is clinically relevant.…”

Precision and trueness of dental models manufactured with different 3-dimensional printing techniques

“…When we compared the 2 techniques, the SLA technique, which involves lower x-y resolution and smaller layer thickness, was more accurate than the DLP technique, but it was less precise than the DLP technique because of the differences in the manufacturing technique. Sweeney et al 12 quantified the trueness of occlusion and defined that an interarch distance with an error of less than 0.5 mm (compared with the gold standard) is a successful occlusion. The range of error (\0.5 mm) was determined based on the clinical validity and the standard set by the American Board of Orthodontics' increments for grading plaster models.…”

“…Occlusion was measured on the basis of interarch distances. 12 The maxillary and mandibular models were occluded by the union function of the Geomagic Control software, and the distances between the half-ball markers of the left and right central incisors, canines, and first molar cervixes on the maxillary and mandibular models were measured.…”
