Nanometer silicon coating surface modifying method for dental non-silicate base ceramic

Abstract

The invention discloses an improved method for the dentistry nonsilicate base ceramic bonding area, belonging to the tooth repair technology, which includes a film forming technology and a heat treatment step of the prosthesis after film forming, and under the pressure of 0.2 MPa the dentistry ceramic prosthesis is processed with sand blasting for 20 s using 110 mu m alumina, then is put in the anhydrous alcohol for ultrasonic cleaning about 10 min to dry. A nm silicasol with the density 40% is used to brush the coating on the sand blasting surface evenly, then is put in a closed environment with the relative humidity 60-70% for drying 24 h, and then for a heat treatment. The beneficial effect of the invention is that, a high quality coating is prepared on the complex dentistry nonsilicate base ceramic prosthesis bonding area, which simplifies the operation step, reduces the cost, and reaches the aim of advancing the ceramics/resin bonded strength in the principle without affecting the esthetic effect, while the relative materials and the devices are not imported, which accords with the the situation of a country and has good clinical application foreground and higher actual value.

AI Technical Summary

Benefits of technology

This technology allows for better quality coating onto complicated teeth by creating strong bonds between them while reducing costs compared with traditional methods like adhesive or resins alone.

Problems solved by technology

This patents discuss various technical problem addressed in these inventions relating to improving orthodontic implants made from ceramites. Current techniques involve polishing surfaces of cerams to match the desired properties, while current chemically crosslinked compositions have limitations including weakening bonds overtime, poor weld quality, cracks when exposed to acidity, reduced light transmittance through glass windows, increased residual stresses associated with brittle metals, and potential issues like corrosivity. To address these challenges, there exists a demand for novel ways to substitute traditional ceramite based composite material systems.
