2013, Journal of Prosthetic DentistryCitation Excerpt :The results showed that all 4 experimental groups demonstrated an overall tendency to expand rather than contract, which may initially appear to be in contrast to evidence available in the literature. However, existing evidence was based on linear measurement methods between selected points,1,6,8,12 vertical dimension (incisal pin opening) measurements,7,11 or measurements of the posterior palatal border adaptation,9 when contraction was defined as reduced linear distance between 2 points. Based on the widely accepted reasoning that an increase in posterior palatal border opening is attributable to denture base contraction, it was decided to define contraction in 3D terms as an increased distance between the denture base fit surface and the cast surface and expansion as a reduced distance.

2013, Saudi Dental JournalCitation Excerpt :A comparison of the changes in the OVD is an important method for estimating new denture base materials and processing techniques (Barbosa et al., 2002). Several studies have reported that the incisal pin can rise from the incisal table after dentures are processed by using dental stone investing medium and the compression molding technique (Kharat and Fakiha, 1999; Nogueira et al., 1999; Dukes et al., 1983; Dukes et al., 1985; Strohaver, 1989; Nelson et al., 1991). However, studies by Mosharraf et al. (2008); Barbosa et al. (2002), Keenan et al. (2003), and Swords et al. (2000) reported an increase of the OVD of a single denture, rather than the overall pin opening on both the maxillary and mandibular complete dentures.
