Magister Scientiae Dentium - MSc(Dent) / The purpose of this study was to e8tablish standards (norms), based on three-dimensional stereomicroscopic surveys of the anterior implant-bearing area of severely-resorbed human edentulous mandibles. Such standards could possibly be applied towards the development of a series of transmandibular implants which would have wide applications in a broad spectrum of patients. The sample consisted of forty five severely-resorbed human edentulous mandibles eminating from people of various ages, both genders and several ethnic groups. Only 28 specimens were accompanied by pertinent details about the deceased. Measure~ents were made in the anterior mandibular area bounded by the mental foramina.
