The effects of disposable and custommade impression trays on the accuracy of impressions

Comparison of the marginal fit of lithium disilicate crowns fabricated with CAD/CAM technology by using conventional impressions and two intraoral digital scanners

“…A custom tray offers an advantage by providing a uniform thickness of impression material, which improves the accuracy of the resulting cast. 25,26 In this study, custom trays were used to reduce the effect of bulk material on the impression accuracy. Additional factors that can influence the dimensional accuracy of an impression are that the impression is susceptible to dimensional changes over time because of possible instabilities in the tray itself and the impression material.…”

Influence of Custom Trays, Dual-Arch Passive, Flexed Trays and Viscosities of Elastomeric Impression Materials on Working Dies

“…A dual arch impression technique characterizes a major advance in fixed prosthodontics and has many benefits over conventional impression techniques in the construction of single crowns [14]. They enable the dentist to use one tray and a single, double-sided impression to imprint the prepared tooth, the adjacent teeth and the opposing teeth, all in their normal, physiologic position of maximum intercuspation [3][4][5]15].…”

An alternative impression technique for individuals with special care needs

“…At the same time, it ensured controlled placement, stabilization, and removal of the impression. Impression quality is favored by short‐span impressions because they are less prone to distortion compared to long‐span ones 23 . Additionally, the use of two (partial) trays instead of one (full‐arch) reduces the risk of eccentric orientation during seating of the impression, which would result in a nonuniform thickness of impression material 24 .…”

“…Impression quality is favored by shortspan impressions because they are less prone to distortion compared to longspan ones. 23 Additionally, the use of two (partial) trays instead of one (full-arch) reduces the risk of eccentric orientation during seating of the impression, which would result in a nonuniform thickness of impression material. 24 Proper thickness of the impression material can be further accomplished by selecting different sizes of partial trays for the left and the right side of the jaw.…”
