Background technology
Tooth-planting is the emerging technology that multidisciplinary intersection such as oral surgery, prosthetic dentistry, science of dental materials and biomechanics, bionics and medical aesthetics produces, and has been acknowledged as in the modern Clinical Science of Stomatology development frontier of tool potentiality.Its development and maturation have greatly been improved stomatologic present situation, have promoted stomatologic development.Along with the development of oral implantology, implantation body not only wants to satisfy basic masticatory function and recovers, and also wants to recover even to beautify local aesthetic, also wants on the structure simultaneously to reach the mechanical property requirements that dummy is supported.But still there are some problems in manual tooth planting's body, as it is little to bear the interlock ability; Plant the body part and stress concentration occurs, cause frontal resorption; The osseous tissue healing rate is slow, and primary stability is difficult to guarantee.
Summary of the invention
At above mentioned problem, the objective of the invention is to reduce local stress for a kind of primary stability height is provided, reduce frontal resorption, shorten healing time, the manual tooth planting's body that increases the service life.
To achieve these goals, the technical solution adopted in the present invention is: manual tooth planting's body, implantation body top is provided with asymmetric screw thread, can bear bigger gmatjpdumamics, and screw thread can be realized auto-lock function, guarantee that implantation body can not become flexible under the effect of no external force, the top of screw thread is that screw thread shoals, the taper shallow thread of tapered design, can reduce the damage to cortical bone, the accelerated bone healing, the top of implantation body is provided with chamfering, chamfering can increase the contact area with soft tissue, make the more natural of soft tissue form growth, the implantation body bottom is provided with the cylindricality that is slightly less than implantation body's diameter, make implantation body easier to be in place in implant surgery, arc surface is processed in the bottom, arc surface is dispersive stress effectively, avoid stress concentration and root to the damage of spongy bone, implantation body is inner and the base station coupling part is locked by Morse's taper and cross and structure is formed, described cross closing component structure is made of the structure sheet, and Morse's taper can make connection more firm, and the cross closing component structure can prevent the base station rotation effectively, the sealed below of cross is provided with circular hole, and the below of circular hole is provided with a standard thread blind hole.
Implantation body's profile presents cylindricality, and upper taper is directly located to present in the end, and bottom cylindricality, upper taper angle are 5 °.
Implantation body adopts asymmetric screw thread, and pitch is 0.8 mm, and the depth of thread is 0.3 mm, and the angle of screw thread lower limb and horizontal plane is 20 °, and top edge is that radius is the arc transition of 0.4 mm, and the top is the cambered surface of 0.1 mm.
The implantation body bottom is arc surface and planar profile, and cambered surface radius is 2～5 mm, and planar diameter is 1 mm, and arc surface top, the end is the cylindricality less than end neck, and length is 0.5 mm.
Implant neck is the chamfer design of 0.2 mm.
Described implantation body inside is provided with pore structure, and the angle between top vertebral foramen bus and the axis is 17 °, dark 0.8mm.
With taper hole be close to for the cross closing component structure, the degree of depth 1.8 mm, high 1 mm of cross locking piece.
The sealed bottom of cross is pore structure, and hole depth 1 mm is provided with the fillet that radius is 0.2 mm at the bottom of the hole.
Be provided with the standard thread blind hole in the hole, dark 2.2 mm of blind hole.
Patent of the present invention can obtain following technique effect owing to adopt above technical scheme: 1, the plantation profile presents cylindricality, and upper taper is directly located to present in the end, the bottom cylindricality, column construction can the most effective dispersive stress, and the neck place is 5 ° of tapers at the bottom of the top, bears bigger stress.2, screw thread is asymmetric screw thread design, can bear bigger gmatjpdumamics, and screw thread can realize auto-lock function, guarantees that under the effect of no external force, implantation body can not become flexible.3, the screw thread top degree of depth shoals, and the damage of cortical bone is reduced, and the bone that is beneficial to implantation body is integrated, and can prevent the intrusion of microorganism and other pollutant simultaneously effectively, is beneficial to the healing rehabilitation of implantation face.4,5, neck portion design is in an inverted cone, is conducive to the release of induced osteogenesis albumen, promotes bone to integrate, and increases primary stability.6, bottom arc surface design makes the easier dispersion towards periphery of stress, avoids bottom stress to concentrate, and lowermost end is the plane, makes implantation body more stable.7, be close to arc surface bottom for diameter is slightly less than the cylindricality of neck at the bottom of the implantation body, easier to be in place when implantation body is implanted.8, implantation body and base station coupling part are designed to Morse's taper and add the cross closing component structure, make connection more firm, and can prevent rotation effectively, increase long-time stability, improve implantation body's success rate.
