Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described, but this utility model is not confined to these detailed description of the invention.One skilled in the art would recognize that this utility model covers all alternatives, improvement project and the equivalents that may comprise in Claims scope.
With reference to Fig. 1-5, a kind of implantation body, comprise the parent 1 of a hollow, the centre of described parent 1 accommodate one rotatable after be screwed into the king bolt 2 of alveolar bone, its side be equipped with multiple rotatable after be screwed into the primary screw 3 of alveolar bone, the bottom of described king bolt 2 and primary screw 3 is all towards alveolar bone and can be screwed into the tip of alveolar bone, the middle part of described king bolt 2 is provided with the conical inclined surface 21 of band profile of tooth lines, the screw terminal 31 of described primary screw 3 is circular platform type structures of a side straps profile of tooth lines, the side of described circular platform type structure is connected with a joggle with the conical inclined surface 21 of the king bolt 2 driving primary screw 3 to rotate.This utility model increases the king bolt 2, the primary screw 3 that are connected with alveolar bone in existing columniform implantation body, add implantation body and synestotic surface area, improve the stability that implantation body implants the rear initial stage, also can be used as the support of bone guided simultaneously, guide new bone apposition.And primary screw 3 is synchronized with the movement with king bolt 2, the horizontal conveyor moving downward drive primary screw 3 of king bolt 2, synchronously completes and is screwed into alveolar bone, convenient to operation.
Described in the present embodiment, the spiral shell body of king bolt 2 and primary screw 3 is all threaded with parent 1, makes king bolt 2, primary screw 3 motion stabilization.
Parent 1 described in the present embodiment is a cylindrical structural body.
Described in the present embodiment, primary screw 3 is provided with three, and the setting of 120 °, interval, utilizes leg-of-mutton stability, reach the object of primary stability.
Parent 1 and the common implantation body of this utility model implantation body do not have too large difference, but it is hollow, wherein contain a king bolt 2 and three primary screws 3.When not yet king bolt 2, primary screw 3 being back-outed, parent 1 is exactly a columniform implantation body, but its bottom surface and side have one and three holes respectively, back-out for king bolt 2 and primary screw 3.Wherein, three holes of side in same level, every 120 degree of existence one.
King bolt 2 and primary screw 3 stablize and synestotic most important part at implantation body's implantation rear increase initial stage.King bolt 2 is made up of the screw terminal turned for screwdriver and screwed spiral shell body, its tip is sharp-pointed, can be used for and pierce alveolar bone, but there is a conical inclined surface 21 its centre, inclined-plane has and has more deeply and more sharp-pointed lines from top to surrounding, this lines is for contacting and transmission with primary screw.The screw terminal of primary screw 3 has also been designed to truncated cone-shaped, its screw terminal 31 has the lines that the conical inclined surface 21 with king bolt 2 matches, and its spiral shell body is the same with king bolt 2, and with lines, its tip is sharp-pointed, can pierce alveolar bone.Therefore, when turning king bolt 2 clockwise at vertical direction, because two tangent and the linear velocity (direction, size) contacting good inclined-plane is identical, primary screw 3 transmission in the horizontal direction can be realized simultaneously, add that the conical inclined surface 21 of king bolt 2 does not stop to move down, primary screw 3 is under its thrust, and outside rotates clockwise, thus enters in alveolar bone.
When all screws are all back-outed, a screw has straight down been stretched out in the bottom surface of implantation body's parent 1, three horizontal direction screws have then been stretched out in the side of implantation body's parent 1, if the ratio of the length of king bolt 2, primary screw 3 and implantation body's parent is through reasonably designing, the tip that can realize four screws forms four summits of a positive triangular pyramid, utilize leg-of-mutton stability, reach the object increasing primary stability.These screws can increase implantation body and synestotic surface area, reach better bone and stablize, also can be used as the support of bone guided simultaneously, guide new bone apposition.Because the basis of this implantation body design is less diameter, and has multiple screw and be distributed in surrounding, therefore can realize the stability that relatively little implantation body has large implantation body, and avoid large implantation body to bring because oppressing the shortcomings such as the osteonecrosis that causes.
