As a consequence of lack of pulp structure and periodontal ligament (PDL), that are regarded as the mainly pain origins of tooth painful sensation, dental implant have the opportunity for painless molecular releasing and blood monitoring with lengthy-term regular and continuous properties. The new pathway could allow purposeful peptides and even the larger molecular releasing and monitoring, which is impossible to absorb all through the gastrointestinal (GI) tract. Therefore we design the replaceable drug supply and bio-sensing modules above the titanium dental implant fixture which is immobile contained in the maxillary bone marrow. The drug supply module comprises the piezoelectric micro-pump, the drug container and the ability supply inside, whereas the bio-sensing module is constructed by the integrated circuit (IC), the Bluetooth module and the power supply. The whole loading volume of the drug supply module is around 0.5-1 ml and the drug is polymerized as a result of safety concern. Therefore the drug releasing type throughout this module is slowly and repeatedly diffused into the surrounding blood pool inside the bone marrow. The released drug sort additionally must be fastidiously selected to avoid surrounding bony destructions. In contrast, the biosensor might provide various molecular types of continuous blood monitoring inside 5 minute intervals and lasting for about 1 month within current know-how. With normal dental and medical protocol institutions, the gadget could present extra helpful functions in clinical practice.
