Laser gingival retraction
In porcelain crown restoration, in order to achieve better cosmetic effect, the crown edge is usually placed in the gingival groove, which usually requires the use of gingival placement technology to shrink the gingival margin and expose the gingival groove, so that the impression obtained is more accurate and clear, and finally makes the crown restoration edge meet physiological conditions and the teeth more beautiful.
Laser gingival method
Laser gingival excision uses the thermal effect of the laser to cause gingival tissue to contract, creating a temporary disorganized area between the tooth surface and the gum. Laser gingival drainage is a new gingival drainage method, especially for the gingival drainage of the back teeth, which does not reduce the height of the gingival and has a fast speed. Usually, it only takes 45 to 90 seconds for a tooth, and has almost no damage to the tissue. 1-2 weeks later, the tissue can be completely restored to normal.
In recent years, laser has been widely used in oral cavity with the advantages of pain, precision and small loss, the amount of gingival retreat after laser gingival drainage is closer to the thickness of intrasulcus epithelium is much greater than 0.2mm, and some studies have shown that laser gingival is very effective, producing a gingival sulcus width of approximately 0.48 mm. Semiconductor laser light waves specifically absorb hemoglobin and melanin in the gingival tissue and pass through the thermal effect will break it down, mainly on soft tissue, the pain is less on soft tissue is better than gingival line protection.
The advantages of laser gingival retraction
Laser gingival retraction is less traumatic to the gums, faster, and can achieve better results than conventional gingival retraction lines after skilled operation.
Laser gingival retraction uses a low-power laser to create a gap of about 0.5-1 mm in the gingival sulcus without reducing the height of the gingiva.
The obtained impression is more accurate and clear, and finally the edge of the crown restoration conforms to physiological conditions and the teeth are more beautiful.
