Abstract
No one really doubts that the hottest area of dentistry in 21st century would most likely be `implant´. With the support of a vast amount of research, implant has been successfully and rapidly absorbed into the field of general dentistry including private practitioners.
For teeth with hopeless(or refractory) periodontitis or periapical pathosis, with no hesitation most dentists would think extraction as the sole treatment option followed by prosthodontic replacement possibly including implant.
Not many dentists would take Trasplantation/Replantation as another treatment option for a particular condition. Dentistry is often more focused on `Restoration´ than `Preservation´ of natural dentition. `Biologic Implant´ is obviously much closer to the concept of `Preservation´. Many different types of biologic implant system have been introduced to clinical dentistry so far. Many of those have failed to earn reasonable acknowledgement despite of the clinical success they brought. For some reason biologic implant has rather been alienated for long time.
RPI(Ring Pin Implant) is designed to improve the prognosis and success rate of transplanted/replanted teeth.
RPI is a Ti-based custom made implant system. It is fabricated either by electric casting or milling process.
The major feature RPI gas is the `ring & hole´ structure. The hole should be no less than Imm diameter to allow bone bridge formation thru it. The ring structure and bone bridge formation creates anti-torque activity, which largely increases the `initial stability´ of the transplanted/replanted teeth. It is also reported that RPI is beneficial in the aspect of resisting root resorption following replantation/transplantation procedure.
