A biofunctional dental implant system for affixing a crown to an implant socket that is made in the bone structure within the mouth of a dental patient. A root portion is initially anchored within the implant socket made in the patient's bone structure. According to a first embodiment of this invention, the crown is secured to the root portion by a flexible abutment post. According to a second embodiment, the crown is secured to the root portion by a hollow abutment tube. The dental implant system of this invention is capable of increasing bone/implant stabilization and providing a supply path through which to evenly distribute human growth factor to the bone structure surrounding the root portion. The system also enables the crown to have a selectively controllable mobility relative to the root portion that is anchored within the implant socket so as to advantageously function like a natural tooth.
