Fluid and tissue processing (1)

IDEAL CONTROL REQUIREMENTS FOR TISSUE


Stopping bleeding soft tissue must be displaced, horizontally and vertically and dry clean fabrics


separators Purpose of use Gingival:

1) Exposing the gingival margins temporarily preparation carved.
2) Provide space in the lateral and vertical between the gingival margin and gingival end for access by the media.
3) Check the fluid without harm gingival tissues.

SEPARATION METHODS GINGIVAL

technique preserves:
Mechanical:
• copper or aluminum bands
• Temporary crowns
• acrylic copings

Mechanical-chemical :
• retraction cords impregnated with chemicals.

SURGICAL TECHNIQUE: Surgical
:
• Electro surgery
• rotary gingival curettage

mechanical methods.

1) TECHNICAL COPPER RINGS .- You can use strips of copper or aluminum, which is trimmed, smoothed and adapt to the gingival margin without pressing the soft tissue and controlling the occlusal or incisal height is filled with modeling softened low melting or elastomers, which displaces the soft tissue between the gum and impress the preparation.

2) PROVISIONAL CROWN ACRYLIC .- provisional acrylic resin crowns over-extended and cemented gingivally for 24 hours;

3) .- acrylic sleeves replaces the copper strips. With satisfactory results in terms of precision printing. The principle remains mechanical method that can be traumatic because of the difficulty of controlling the pressure exerted on digital printing and time action.

PRECAUTIONS IN THE USE OF MECHANICAL METHODS:

result can cause:

-irreversible separation from excess pressure,

-tearing of the gingival tissue and junctional epithelium among others.

MECHANICAL-CHEMICAL METHODS:

1) GINGIVAL separating yarns impregnated with chemicals.
To produce the displacement of the gingival barrier. Procedure
reversible and low-trauma. Extracellular matrix proteoglycans
the entire oral epithelium absorb water and nutrients
By compressing the tissue, the proteoglycan content and determines empty resilience.

The gingival tissues must be healthy to start a restorative treatment, special care when the free gingiva is thin and only a small area of \u200b\u200battached gingiva, it may cause irreversible traumatic gingival retraction

 Used to finish either in biological preparation cervical end. 
or after finishing the carving of the teeth to allow access to print materials to limit the scope cervical root.

WIRE SEPARATION GINGIVAL

not medicated

 has the advantage of no adverse reactions or systemic effects unwanted. 
Generate a minimum of damage to the gingival tissues, which decreases markedly the risk of gingival recession. 
are safe when left up to 30 min. but has little ability to shrink the wires medicated medicated



may occur embedded in a chemical solution or embedding.
These chemicals can be: 
Hemostatic Astringents or aluminum chloride.
 
ferric sulphate aluminum sulphate. 
epinephrine or adrenaline.
