简要总结
In fixed prosthodontic treatment, deflection of gingival tissues for diagnosis or making an impression is one of the important phases. Gingival displacement is defined as "displacement of gingival tissues both in vertical and lateral dimensions". Lateral retraction displaces the tissues so that an adequate bulk of impression material can be interfaced with the prepared tooth. Vertical retraction exposes the uncut portion of the tooth apical to the finish line Conventional gingival retraction cord technique may injure the healthy epithelial lining and result in postoperative gingival recession The diode laser has been used for displacing gingiva to make a definitive impression. Rather than displacing gingival tissue, it removes the epithelial lining from the sulcus.
The aim of the Study is to compare between the Ultrapak retraction cord and diode laser regarding the amount of vertical and lateral retraction and patient comfort.
