History Of Dental Gum Development

Dental glue is a mold glue for the structure of the gums when the wisdom teeth are filled. In the development of its raw materials, the first is to use alginate which is low in price but easy to shrink, low in mechanical strength (Achilles heel), and prone to bubbles. Later developed into a weaker than alginate, the catalyst has toxic polysulfide compounds and a polystyrene rubber that is odorous and difficult to disinfect. Finally developed into a widely used hydrophilicity and fluidity, odorless, good dimensional stability (no shrinkage), deformation rate <0.1%, already cured and crosslinked multiple high temperature sterilization Formed silica gel.

Dental adhesive itself needs to have good dimensional stability (following processing for porcelain, long time, can not shrink and deform), long operation time (from stirring to long covering time), short curing time (for patient comfort) , the tooth gel can be uncomfortable in the oral cavity for a long time), the appropriate strength (the material must be removed without damage and complete peeling), fluidity and viscosity (the tooth gel needs to enter the fine part), non-toxic and easy to disinfect (avoid Infected sensitive patients), hydrophilic (guaranteed mold taking, and saliva), hardness can not be lower than 55 ° (to ensure that the cast gypsum is not deformed) and other properties to ensure smooth use.

Addition molding silica gel is divided into silicon powder calcium carbonate, raw rubber, silicone oil, hand-kneaded particles type 0 (sub-component A and component B, 1 to 1 ratio, then use a spoon to pill, can be hand-kneaded and then placed Into the tray to use). It has a large viscosity and is less viscous than type 0. It is less fluid than toothpaste and is difficult to squeeze. Type 2 with a viscosity less than 1 type. The viscosity is less than type 2, the viscosity is the lowest, the fluidity is good, and the hardness is moderate and elastic.

In the material of dental plastic raw materials, white carbon black has an effect on the fluidity, is very thick, and has a large viscosity, which can not reach the fine mold, and only a small amount can be added. Silicone guarantees fluidity and proper hardness but is expensive. So in most cases, considering that performance and cost-effectiveness must exist at the same time, the two materials will be added at the same time, and no one will completely replace the other.

The mode of taking the dental glue is divided into one mode and two times. The mold is taken directly by the type 1, 2, and 3, and the glue gun has two hoses, each of which is loaded with a component, and is punched into the non-porous tray through the front mixing head. Remove into the mouth after occlusion. Or type 0 and type 3, the particle shape is evenly spread and then placed in the tray, and the medium opening hole is injected into the type 3 to enter the oral cavity. The modulo removal is generally inaccurate and the fine structure removal is incomplete. The second mold is uniformly pinched by the 0 type and placed in the tray to enter the oral cavity and solidified to remove the structure of the gum. The glue gun is injected into the cured gum bed into the oral cavity for secondary occlusion. The second modulo is highly accurate, but the time is long, which affects the patient's comfort.

Most of the dental gum products circulating on the market today differ in the cure time and ratio. It can be used in a variety of combinations according to the curing time that different patients can accept and the precision that the mold needs to achieve.
