Abstract
The utility model provides a planting body for an artificial tooth with column-shaped threads used for restoring anodontia. The utility model is characterized in that a root is provided with a taper guiding part, a cutting edge which can cut and screw into a bone in a self-tapping mode, an axial ditch against reverse rotation and looseness against self rotation, implantation depths and rotation angles can be regulated, and better firmness can be obtained. The utility model has advantages of convenient operation, beautiful restoration, good effect and wide adaptability.
Description
This utility model belongs to a kind of canine implant product, is used to repair anodontia.
Anodontia is one of a kind of modal illness, seriously influenced chew, language function and face is attractive in appearance, canine implant is the advanced medical skill different with traditional restorative procedure.Its substitutive characteristics is to implant in the mandibular organization of oral cavity with artificial material manufactured goods, and as support, the basis of maintenance, make artificial tooth, repair the disappearance tooth.Canine implant is the implant of the alternative human organ in the medical apparatus.
Be divided into three parts on manual tooth planting's body structure: root--for being implanted in the part in the jawbone; Cervical region--for running through the part of oral cavity gingiva mucoperiosteum; Foundation pile portion--for being positioned at the coupling part of intraoral foundation pile and crown portion.Present existing manual tooth planting's body can be divided into lobate type, column type and taper type three major types by the root form; Be divided into single-piece (being that root, cervical region and foundation pile portion are an integrated member) and combination type (root and other parts are separable members) two big classes again by overall structure.
Column screw-type in the column type is a column, and there is screw thread on the surface, during implantation, forms mechanical embedding knot between screw thread and the osseous tissue, can obtain steadiness immediately.But existing column screw thread manual tooth planting body still has the shortcoming of following aspect: 1, root: 1. screw thread adopts industrial matching thread design, needs tapping formation Luo Dao on the inwall of bone hole during operation.Because of the thin fragility of osseous tissue, be difficult for forming clear Luo Dao, root is difficult to enter by predetermined Luo Dao when screwing in; 2. press matching thread design, the root threaded body enters fully that reach can be firm behind spiral shell road, the bone hole cecum, can only be when screwing till, the root anglec of rotation can not be controlled and adjust; 3. when canine implant is subjected to derotation power, might become flexible because of derotation.2, cervical region: because of cervical region, root and foundation pile diameter all are close, if diameter is little, foundation pile and corona cervical region thickness are inharmonious, influence attractive in appearance; If diameter is big, gingiva tissue is difficult to effectively form sealing again.3, foundation pile: foundation pile and corona are connected and fixed with vertical to screw, and to close face porose because of the corona tooth, influence attractive in appearance.
In order to overcome the above-mentioned shortcoming of column screw thread manual tooth planting body, the purpose of this utility model is to provide a kind of more convenient operation for clinical, can obtain better steadiness at once, and the anti-rotation of the loosening self-taped type of anti-derotation column screw thread manual tooth planting body product is arranged after the healing.
Major technique content of the present utility model: the anti-rotation of self-taped type column screw thread manual tooth planting body is a kind of column screw thread manual tooth planting body, is made of root (1), cervical region (2) and foundation pile portion (3).There is tapering guide portion (6) the root lower end and cutting edge (7) is arranged, and root has three axial anti-derotation ditches (8), and the root depth of thread is deepened to the root tip gradually from the upper end, is tapping screw thread (9).Cervical region has the thin part that contracts.Foundation pile portion and root are combination type, fix with the chimeric center bolt (12) that adds of outer six sides (11) of foundation pile with six sides (10) in the root.
Root (1) lower end tapering guide portion (6) and cutting edge (7) and tapping screw thread (9) can be finished the self tapping effect, screw thread keeps closely contacting with the bone wall in the self tapping process, do not need to reach fully just can obtain at the bottom of the bone hole firm at once, root screws direction and depth controlled system and adjusts with the need, three axial anti-derotation ditches (8), the bone scraps that thread tapping cuts down in the time of can holding implantation body's screw-in, osseous tissue forms chimeric in the ditch of growing into after the knitting, stop rotation loosening, tapping screw thread (9) pitch equates that the spiral shell trench depth is deepened to the root tip gradually from the root upper end.Major diameter of thread is a cylindricality.Cervical region (2) contracts and carefully partly is convenient to the soft tissue sealing.Foundation pile (3) end maximum gauge and the thinnest diameter ratio of cervical region are greater than 5: 3, between the thinnest section diameter 2.8-3.2mm.There are two kinds of combination type and single-pieces in this implantation body, and both root structures are identical.Combination type implantation body, its root and foundation pile are fixed with the chimeric center bolt (12) that adds of outer six sides (11) of foundation pile by six sides (10) in the root.Foundation pile is a frustum, and horizontal screw (4) or vertical threaded bore (5) are arranged, and laterally screw can be realized demanding corona reparation attractive in appearance.The foundation pile of single-piece implantation body also is a frustum, and vertical or horizontal screw is also arranged.The foundation pile wall has two axis of symmetry ditches (13) or two planes to hold for the screw-in instrument.
The design's major advantage and good effect: 1, the anti-rotation of self-taped type column screw thread manual tooth planting body has tapering guide portion, cutting edge and tapping screw thread, can finish the self tapping effect, does not need tapping formation Luo Dao on the bone hole.2, axial anti-derotation ditch can hold the bone scraps that thread tapping scales off when screwing in, and the osseous tissue of growing into after the knitting forms chimeric, stops rotation loosening.3, can obtain steadiness at once in the self tapping process, root screws direction and depth controlled system and adjusts with the need.4, cervical region contracts and carefully partly is convenient to the gingival soft tissue sealing.5, easy to operate, reparation is attractive in appearance, effective, adaptability is wide.
Accompanying drawing and drawing explanation:

Fig. 2 self-taped type column screw thread artificial growth body is analysed and observe and vertical view
Fig. 3 combination type implant neck and foundation pile portion analyse and observe with vertical view figure in sequence number explanation:
(1) root, (2) cervical region, (3) foundation pile portion, (4) are screw laterally, (5) vertical threaded bore, (6) tapering guide portion, (7) cutting edge, (8) axial anti-derotation ditch, (9) tapping screw thread, (10) six sides in the root, outer six sides of (11) foundation pile, (12) center bolt, (13) axis of symmetry ditch.
Embodiment: the long 12mm of root, diameter 5mm, pitch 1mm, tapering guide portion tapering 60 degree, 6 cutting edges, three long 9mm of axial anti-derotation ditch, lonely shape radius 2.1mm, wide 1.2mm, the high 3mm of cervical region, the thinnest diameter 2.8mm of portion, the high 5mm of foundation pile portion, diameter 5mm, round platform tapering 75 degree.
