Comparison between immediate vs. delayed lateral expansion technique to augment narrow alveolar ridges for placement of implants - A pilot study.

Objective: Narrow alveolar ridges pose a serious challenge for successful placement of endosseous implants and alveolar ridge widening procedure is indicated in cases of crest thickness of ≤4.0 mm. The study evaluated and compared, immediate and delayed techniques of implant placement using split crest technique to augment atrophic narrow alveolar ridges.

Polarized microscope assisted study of collagen fibres in Oral Submucous Fibrosis and their clinicopathologic correlation: An in-vitro study.

Background: The present study was aimed to evaluate and analyze orientation and birefringence pattern of collagen fibers histopathologically in different grades of OSMF using the special stain (Picrosirius red) under polarizing microscope and relate these factors with the severity of OSMF.

Materials And Method: 45 confirmed cases of OSMF were taken from the archives. The selection of clinical cases was done according to classification by J.
