Current concepts in gingival displacement Donovan et al 2004 This article discusses the concepts of gingival displacement for optimal impressions Inadequate impressions are frequently forwarded to commercial laboratories, and the chief deficiency seen in such impressions is inadequate recording of the cervical finish lines.

Ferrule Design

Sorensen 1990 Ferrule design and fracture resistance of endodontically treated teeth Sorensen et al 1990 The term coined by Eissman, and he recommends to be 2 mm.

Reduction of the residual alveolar ridges

The continuing reduction of the residual alveolar ridges in complete denture wearers: A mixed-longitudinal study covering 25 years Tallgren 2003 The reduction of the residual alveolar ridges was most rapid during the ﬁrst year of denture wear. 2 groups : In Group C, all dentures were made of vulcanite Group A, the dentures were
