Brief Summary

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.

Gingival retraction by ultrapak retraction cord

ACTIVE COMPARATOR
Device: ultrapak Knitted retraction cord

Gingival retraction by diode laser

EXPERIMENTAL
Device: diode laser

Interventions

using Ultrapak Knitted retraction cord as a gingival retraction method . using Wiser Cordless Dental Diode Laser from Doctor Smile Dental Laser By LAMBDA SpA Italy as a gingival retraction method.• The tip of diode laser, will be angled toward the soft tissue and away from the prepared tooth, will be passed along the gingival sulcus to remove the sulcular epithelium. Constant and steady short brushing strokes gently removed the lining of the sulcus in order to achieve a full 360-degree trough. The tip will be constantly cleaned with a gauze sponge wetted with hydrogen peroxide to remove debris and to eliminate potential bacterial contamination. sufficient epithelium will be removed to place the impression material and visualize the finishing line. The tissue will be kept moist with water during the procedure then impression will be taken

Gingival retraction by diode laser

using Ultrapak Knitted retraction cord as a gingival retraction method retraction cord will be applied for 8-10 mins then an impression will be taken , poured to obtain a cast and the die sectioned
