Description

Technical Field

[0001] The utility model relates to the technical field of dental restorations, in particular to a device for strengthening dental restorations. Background Art

[0002] Dental restorations play a vital role in modern oral rehabilitation and are used to repair teeth damaged by caries, injuries or other reasons. Traditional restoration materials, such as metal alloys and ceramics, have certain limitations. Micro-glass ceramics are favored by people because of their mechanical indicators and translucency that are closer to natural teeth and easy mechanical processing. It is extremely important to improve the mechanical properties of dental restorations while maintaining aesthetic properties.

[0003] Dental restorations can form a surface compressive stress layer through chemical strengthening to achieve the purpose of strengthening glass ceramics. Commonly used ion strengthening replaces smaller ions (such as lithium ions) on the surface of glass ceramics with sodium ions or potassium ions with larger ion radius to change the composition and structure of the glass surface and form a higher surface compressive stress, thereby achieving the purpose of strengthening. However, in conventional ion strengthening, the preheating and cooling process during the molten salt bath immersion process is relatively complicated, and problems such as salt bath volatilization greatly limit the use of ion strengthening.
