ABSTRACT:
An oral implant for supporting an artificial tooth structure includes an implant portion that has a transverse slit at an obtuse angle to the side wall such that two facing surfaces are created. By squeezing the surfaces toward each other, the surfaces make contact and slide along each other so as to laterally separate the two parts of the implant portion. This causes the implant portion to become tightly wedged in a groove in a patient's bone along the occlusal plane. Additionally, the implant includes a neck portion with a rotatable threaded collar that couples to threads on a cap to which the artificial tooth structure is secured. As a result, the tooth structure can be removed without damage to it or to the implant.
