Do you know what materials are needed to fill a tooth?
Do you know what kind of material is suitable for you to use for filling?
Director Jiang of the Stomatological Hospital will introduce the filling materials for you: according to the nature of the materials, the filling materials can be divided into: 1. Mercury agent: composed of mercury and alloy powder; 2. Resin: composite resin with synthetic resin and natural resin; 3.
According to the retention time of the material in the hole, the filling materials can be divided into: 1. Short-term use materials, such as temporary hole sealing materials in the treatment process, clove oil zinc oxide adhesive powder can be used within 2 weeks, zinc phosphate adhesive powder can be used within half a year.
2, long-term use of materials, namely permanent filling materials, in the hole to replace the defect of dentine long-term retention, such as silver amalgam, composite resin, etc.
What are the materials for tooth restoration?
1. Silver amalgam is an amalgam compound of interaction between mercury and silver-tin alloy powder, which is most commonly used in clinical practice.
It is mainly used in class I and ¢¢ holes that need to bear dental force and class ¢¥ holes that need not consider aesthetics.
A hole for clasping the abutment teeth;
The post core or the inner filling body of the full crown restoration.
When silver amalgam is used to restore teeth, it is necessary to maintain a certain volume so that the teeth can withstand the resultant force without breaking.
Since silver AMALGam and tooth tissue do not have adhesive property, it is necessary to prepare a box hole, design a good retention shape, make the two closely fit, mutually chimERism, good moisture isolation, in order to make the silver amalgam repair teeth firm and lasting.
2, composite resin is in the organic synthetic resin plus a large number of special treatment of inorganic material filling material, with the help of tooth surface treatment technology, make it bonded to the tooth hard tissue, mostly used for class ¢£ hole, class ¢¥ hole filling;
High strength composite resins are also available for filling class I and class II holes in posterior teeth.
The adhesive technique can also be used to repair the affected teeth with class ¢¤ holes and severe tooth defects.
Photosensitive curing composite resin, its color is stable, strong adhesion, especially suitable for anterior teeth beauty restoration;
Chemically CURED COMPOSITE RESIN, EASY TO operate, although slight color change, is suitable for posterior teeth and lingual (palatal) lateral cavity of anterior teeth.
3. Polycarboxylate adhesive powder (also known as polyacrylic acid adhesive powder) is a kind of bottom and adhesive material.
It can be used as the bottom material of the hole, the sealing material of the hole within half a year, or the QQ group of the dental network to understand: 33¡¤03-4302, the root canal filling material, can be used as the crown bridge of the bonding agent, and can be added as the periodontal plug treatment agent.
4, glass ion polymerization adhesive powder is a kind of dental pulp stimulation light, on the tooth hard tissue adhesion, but the strength of silver amalgam is much lower than the use of materials.
It is suitable for class ¢£ and class ¢¥ cavities. It is used for filling deciduous teeth and as cavity sealant to prevent caries.
