Gingival Management (Tissue Displacement)

• Electrosurgery

• Retraction cord

Gingival management/Tissue displacement is best achieved through what operation/procedure?

Gingival Management/Tissue Displacement

Common needed to obtain adequate access to the prepared tooth to expose all necessary surfaces, both prepared and not prepared

Displacement/Retraction cord

Enlargement of the gingival tissue can be obtained by placing a non-impregnated cord and leaving it in place for several minutes.

Displacement/Retraction Cord

Mechanically stretches the circumferential periodontal fibers

Braided or knitted

Placement of retraction cord is easier if the cord is:

• Aluminum Chloride

• Iron Sulfate

Better sulcus enlargement with chemically impregnated cord or by dipping in an astringent and causes minimal tissue damage

Mesial Interproximal Area

Excess cord is cut off in what part

Good impression

A well retracted gingiva will result to a good _____ of the gingival margin

Electrosurgery

May be used for minor tissue prior to impression making

Electrosurgery

The inner epithelial lining of the gingival sulc8s is removed, pr0viding access for a subgingival crown margin

Retraction Procedures for the anterior region — Techniques

Single string

Indication of this retraction procedure is healthy tissues

Selective Double String

Indication of this retraction procedure is healthy tissues with localized irritation

Double string

Indication of this retraction procedure is Inflamed tissues

Selective double string

Advantage of this retraction procedure is good lateral displacement
