ABSTRACT:
A one-piece dental implant having a longitudinal axis comprises a head portion at a first end of the implant, a tip portion at a second end of the implant and a body portion between the head portion and the tip portion. The body portion has a first portion proximate the head portion with a plurality of longitudinal grooves substantially parallel to the longitudinal axis and a second portion proximate the tip portion having a substantially circumferential groove, wherein the outer diameter of the first portion is greater than the outer diameter of the second portion. The first and second portions are for being embedded in the jaw bone. The dental implant is preferably dimensioned to conform to the natural shape of the cervical ⅓ of the root of the tooth being replaced, and to the natural relationship between the cemento-enamel junction of the tooth being replaced and to minimize adverse immunological responses by the jaw bone during healing, thereby improving the aesthetic appearance of the implant and prosthetic tooth attached thereto. A dental implant and prosthetic tooth system is also disclosed, wherein the prosthetic tooth conforms to the shape of the cervical ⅓ of the crown of the tooth being replaced. A method for implanting a dental implant through use of a reference, is also disclosed.
