Abstract
An endosteal implant including at least one piece having a body intended to be embedded in the bone, one of the ends of which is intended to be flush with the cavity of the mouth or to be in projection in this cavity, and the dimension of which, when considered in a parallel direction to its longitudinal axis, is such that the body extends through the upper cortical area, the blueberry tissue and the lower cortical area of the bone. The body part which is intended to be embedded in the upper cortical area and to be flush with the cavity of the mouth or to be in projection in this cavity has a cross-section, when considered perpendicularly to the axis, which is lower than the corresponding cross-section of the part which is intended to be embedded in the blueberry tissue and in the lower cortical area.
Claims25
A mandibular endosteal implant for a mandible having blueberry tissue enclosed within an endosteum perimetrically defined by bone of a lower cortical area, a lingual cortical area, upper cortical area and a vestibular cortical area, mucosal tissue of a patient's gum intervening between the upper cortical area and a patient's oral cavity, and an opening having a given width and being formed along a generally vertical axis through said mucosal tissue and said upper cortical area into said endosteum,
- said implant comprising:
- a body having a lower portion of a first, larger transverse (relative to said axis) cross-sectional area and a width greater than said given width, said lower portion being arranged to be received in said endosteum and embedded in said blueberry tissue and said lower cortical area, and an upper portion of a second, smaller transverse cross-sectional area projecting upwardly from said lower portion, along said axis, and projecting upwards within said opening to at least a level of flushness with said oral cavity;
- said upper portion terminating in an upper end which, when said lower portion is embedded in said lower cortical area, is arranged to be accessible from said oral cavity.
