Abstract
A dental implant and bone preservation and regeneration arrangement and method of implementation is disclosed. The dental implant arrangement includes an implant body screwed into a patient's alveolar bone. An abutment on the implant body collar portion receives a crown. The implant body, the abutment, the crown, the implant body/abutment junction or the abutment/crown junction includes a "macro-feature" such as a "macro-gap" or "macro-protrusion" large enough to encourage gingival tissue growth in and/or around the feature. The growth prevents oral bacteria from getting below the level of the macro-feature. The arrangement reduces bone loss and encourages bone regeneration. The macro-feature can be progressively repositioned to regenerate bone.
