Bionic restorative system: its potential value in caries therapy

Dental defect caused by dental caries is usually restored by fillings, inlays or onlays at the present day. Although the therapeutic effects of these methods have already been confirmed, complications occasionally set in, such as pulp injury, fracture and secondary caries. Bionic dental organic center possesses similar functions of the natural dental organic center. So we put forward a hypothesis that bionic organic center can be transplanted onto the conditioned pulpal walls of the prepared cavity and a specific filling material, which the cavity will be filled with, provides oxygen, nutrition and raw materials for it to regenerate the lost odontal tissue in vivo. The regenerated odontal tissue which has similar properties of the healthy odontal tissue will restore the defect and it will be combined with the residual odontal tissue tightly, not only in physical structure but also in function. Then the teeth suffering from dental caries could live and function like healthy ones.
