Definitions
- the invention relates to a composition intended to improve the physico-chemical characteristics of materials based on natural or artificial apatite, in particular implants. It also relates to the use of titanium derivatives for the reinforcement of apatite-based materials, as well as to a process for the reinforcement of apatite-based materials.
- a large part of prostheses or implants for dental or medical use is made from titanium.
- the visible part of the tooth has a natural color which changes over time. This color depends in particular on the whiteness and transparency of the dental enamel, as well as the color of the underlying dentin. Enamel and dentin are generally whiter the less mineralized their main constituent, hydroxyapatite. Thus, in the absence of anomaly, the tooth is then a white-ivory color. However, different phenomena occur over time and have an influence on the color of the teeth.
- extrinsic stains can change the color of the tooth.
- certain foods such as coffee, tea, blueberries contain colored pigments which can attach to the surface of the teeth and alter their shade.
- Other substances such as tar contained in cigarettes or certain drug treatments can act in the same way and change the color of teeth.
