ABSTRACT:
A dental implant system utilizes a threaded implant which is cylindrical in form and has a large number of longitudinal channels so it can be (i) screwed into place in a bore hole in the patient's bone, (ii) pushed into place or (iii) first pushed into place and then turned to anchor it in bone ridges formed when it is pushed into place. Also an implant is given a conical shape it can be used for supporting artificial teeth in a residual ridge crest of a patient by drilling a smaller than normal cylindrical hole in the crest and carefully inserting the conical implant so that the bone is spread and makes additional contact with the implant.
