Quick, painless, and atraumatic gingival retraction: An overview of advanced materials.

The success of any fixed prosthesis depends on the accuracy of impressions. Finish line exposure has to be adequate during impression making. The goal of gingival retraction is to atraumatically displace gingival tissues to allow access for impression material to record the finish line and provide sufficient thickness of gingival sulcus so that the impression does not tear off during removal. Numerous advanced materials are available for gingival retraction. This article describes the different advanced materials available.

A computed tomography study in the location of greater palatine artery in South Indian population for maxillary osteotomy.

INTRODUCTION: The greater palatine artery is one of the important feeding vessel to the maxilla. The surgeon should know the surgical anatomy of greater palatine artery to avoid trauma in maxilla which leads to ischemic problems. AIM: The CT evaluation of the distance between Pyriform aperture and the greater palatine foramen in various ages of both sexes. RESULT: The distance varies according to sex and age which are measured by CT and standardised. DISCUSSION: The lateral nasal osteotomy can be done upto 25 mm depth, instead of 20 mm. CONCLUSION: By this study it shows that the lateral nasal wall osteotomy can be performed without injury to greater palatine artery.
