Dental implant fixture for anchorage in cortical bone

摘要

A dental implant fixture intended for installation in maxillary and mandibular posterior regions where bone is cancellous internally and cortical externally characterized by buccal and lingual cortical plates bounding a relatively large body of cancellous bone. The body of the implant fixture has a width dimension that is substantially the same as the distance between the buccal and lingual cortical plates in the site of installation and has a stop flange of substantially the same width at its gingival end. When the implant is installed in that site the stop flange makes bone-to-implant contact with the coronal bone which joins the plates. The length of this implant fixture is limited so that when so installed it does not make contact with the mandibular canal or the sinus cavity.
