Our mouldable teether sets contain polyvinyl alcohol, polyvinyl alcohol crosslinked polymers. It can. Its use method is very simple :1. Prepare the material to put the powder and liquid on the glass plate or smooth paper in a 2:1 ratio (in practice, the powder ratio is slightly larger, the bonding strength and hardness will be better)2. Dental treatment is carried out, washed, cleaned the tooth surface or cavity (with a probe to remove internal residue), dry (cotton ball drying) Note: after drying, the cavity can no longer be contaminated with saliva, with a cotton ball or paper towel roll between the tongue and the tooth)3. Mix the material with the dental mirror handle (this is a plastic handle, remember not to use a metal tool to adjust, the metal will react with the material (use the material to discolor) Mix the powder and liquid well 4. Use the handle of the dental mirror to fill the blended material. After placing the material into the hole, it is trimmed with a dental probe. Let it cure for about 1 minute. Use a probe to remove excess material from the tooth surface, adjust the height immediately after adjustment, and remove excess material with a wet cotton ball. After 24 hours of filling, the affected side can be forced to bite. And it can accurately conform to the contours of the mouth and fit comfortably.
