Description
Technical field
This utility model relates to oral cavity medical apparatus technical field, relates in particular to a kind of one-part form implanting body of artificial tooth of repairing for edentulous region, common gap.
Background technology
The implant system that " implant tooth " adopts can be divided into one-part form and multisection type according to type.Wherein multisection type implant system is comprised of implantation body, base station and center screw conventionally, implantation body and base station are fixed by center screw, the plantation of this multisection type implantation body needs two operations, and this has not only extended treatment and healing time, has also increased patient's misery.And implant operation can not guarantee complete success for the second time, this all causes very large pressure at heart to patient and doctor's.
One-part form plantation physical ability realizes artificial tooth's disposable plantation at present, but is only applicable in Anterior Implant, cannot meet the needs of the wider common edentulous region plantation of alveolar bone:
1, at present one-part form implantation body is multiplex in Anterior Implant, and the alveolar bone of labial teeth is narrow, so the size of one-part form implantation body is all smaller, causes the intensity of one-part form implantation body low, self tapping poor-performing.
2, current in the situation that guaranteeing implantation body's intensity, the wider common edentulous region of bone wall adopts multisection type implant system more.Because implantation body in multisection type implant system is separated with base station, plant tooth early stage implantation body and be embedded in bone, be not subject to the impact of extraneous gmatjpdumamics, can be stable and synosteosis.And current one-part form implantation body and base station are one, after plantation, base station can be exposed to bone and easily be subject to the impact of extraneous power outward, is unfavorable for knitting.
To sum up, urgently a kind of can be when guaranteeing structural strength, the one-part form implanting body of artificial tooth of repairing for edentulous region, common gap that not affected by extraneous power.
Utility model content
The purpose of this utility model is, problem for above-mentioned existing one-part form implantation body insufficient strength, self tapping poor performance, a kind of one-part form implanting body of artificial tooth of repairing for edentulous region, common gap is proposed, be somebody's turn to do, Sizes simple in structure for the one-part form implanting body of artificial tooth of edentulous region, common gap reparation, can when guaranteeing structural strength, increase the self tapping performance of implantation body.
For achieving the above object, the technical solution adopted in the utility model is: a kind of one-part form implanting body of artificial tooth of repairing for edentulous region, common gap, comprise implantation section that one coaxially connects in turn, wear gum section and base station, the described section cylinder and the frustum that comprise coaxial connection implanted, described cylinder two ends respectively with the bigger diameter end of frustum with wear gum section and be connected, described implantation section surface is provided with screw thread, the miner diameter end of described frustum is arc surface, described cylindrical external diameter is 3.5-4.5mm, described implantation segment length is 8-15mm, is preferably 10mm.The setting of implanting section frustum approaches profile and the natural root of the tooth of implanting section, and to improve the long-time stability of implantation body, the conical surface of this utility model frustum and the angle of horizontal plane are about 70 °-85 °.The stress that can effectively disperse to implant section that arranges of implanting section arc surface, reduces the damage to spongy bone.
Further, describedly wear the first frustum and the second frustum that gum section comprises coaxial connection, the bigger diameter end of described the first frustum is coaxially connected with the bigger diameter end of the second frustum, described the second frustum and implantation coaxial a connection of section, the height of described the first frustum is 0.3-1.0mm, the height of described the second frustum is 1-4mm, and the bigger diameter end external diameter of described the first frustum and the second frustum is 4-6mm.
Further, the external diameter of wearing the miner diameter end of gum section the first frustum described in is 3-4mm.
