Abstract: A filter assembly for elective use in conjunction with a surgical evacuation system is provided which includes a filter housing having a head portion and a body portion with a through passageway extending therebetween defining a filter receiving chamber. The head portion is connectable to an aspirator tip and the body portion is connectable to a flexible suction conduit. A filter element is disposed within the filter receiving chamber of the filter housing. The filter element includes a head member having a fluid flow passageway extending therethrough, a fluid impermeable base member spatially disposed from the head member and a fluid permeable body member disposed between the head member and the base member.

Abstract: An improved cylindrical dental implant for anchoring a dental prosthesis in a hole formed in a jawbone comprising an elongated cylindrical member having a first end adapted to be inserted into the hole and a second end adapted to receive the dental prosthesis. At least one wedge member radially extends from the cylindrical member to effect immediate fixation of the cylindrical member in the hole. The wedge member has a base portion connected to the outer peripheral surface of the cylindrical member and a tapered portion having a first planar face and a second planar face. The first planar face and the second planar face intersect to form a thin longitudinally extending edge.
