Gingival Displacement by Polytetrafluoroethylene & Conventional Retraction Cord

2019-09-17 02:47:29 | BioPortfolio

Summary

To achieve harmony between restoration and surrounding periodontium, soft tissue management plays a pivotal role. Various Gingival displacement techniques show varying results in achieving the goals of displacement. The most preferred method of dispalacement by dental practitioners is through conventional retraction cord made up of cotton, which besides its advantages, poses certain drawbacks, including low tear strength, high friction, and fiber remnants within the sulcus.

Polytetrafluoroethylene (PTFE) retraction cord, is a fluoropolymer, known for its high tear strength, low friction, and bio-compatibility.

This study aims to determine the difference of horizontal gingival displacement between PTFE and conventional retraction cord.

Participants inducted in this study will be assessed for eligibility. qualifying subjects will receive crown preparation for Porcelain-fused to-metal crown. subjects will then be randomly allocated to either of the two arms of intervention. After making a pre-displacement impression, Retraction cord will be applied for 3minutes, then removed to record post-displacement impression.

the difference in pre and post-displacement mean gingival sulcus width will be assessed by a stereomicroscope using image analysis software.

Medical and Biotech [MESH] Definitions

Techniques used to expose dental surface below the gingival margin in order to obtain better dental impression during periodental and peri-implant applications. The retraction of the gingival tissue can be achieved surgically (e.g., laser gingivectomy and rotary curettage) or chemically with a retraction cord.

An abnormal extension of a gingival sulcus not accompanied by the apical migration of the epithelial attachment.

Retraction of a clot resulting from contraction of PLATELET pseudopods attached to FIBRIN strands. The retraction is dependent on the contractile protein thrombosthenin. Clot retraction is used as a measure of platelet function.

An abnormal extension of a gingival sulcus accompanied by the apical migration of the epithelial attachment and bone resorption.

Work consisting of a statement issued by one or more authors of an article or a book, withdrawing or disavowing acknowledgment of their participation in performing research or writing the results of their study. In indexing, the retraction is sent to the editor of the publication in which the article appeared and is published under the rubric "retraction" or in the form of a letter. This publication type designates the author's statement of retraction: it should be differentiated from RETRACTED PUBLICATION which labels the retracted publication.
