Abstract
The utility model discloses a kind of mouth cavity orthodontic Zhi Kangti, its structure comprises base and traction stake two parts; Wherein, base is as inverted dish type, and edge part is belittled, and middle part is abundant, and submounts central part is a platform, and platform central is provided with screw, and screw inwall is provided with female thread; Traction stake is a cylindrical bar, and lower end is provided with external screw thread, and the external screw thread of traction stake lower end combines with the female thread of chassis platform and forms mouth cavity orthodontic Zhi Kangti.Be connected to up/down jawbone surface by medical adhesive dressing, do not need to invade in bone as implantation body, therefore can evade the operation risk of implant anchorage.
Description
Technical field
This utility model belongs to human body embedded type medical apparatus and instruments, particularly implants oral cavity, for correcting the apparatus of oral deformity.
background technology
Mouth cavity orthodontic is the irregular deformity of tooth arrangement formed for tooth self-sow, uses the medical measure that external strength moving teeth adopts.In mouth cavity orthodontic process, the tooth be moved can produce counteracting force while stressed movement, the side effect that this counteracting force must have suitable tissue and device to bring to resist it, a key link---the anchorage of Here it is mouth cavity orthodontic medical procedure.The object bearing correction counteracting force is called as " Zhi Kangti ".Stablize effective Zhi Kangti the most implants titanium alloy implant in alveolar bone at present.The titanium alloy Zhi Kangti of this embedded type, some is because the improper of planting technology makes implant operation fall through, also there is some shortcomings not enough: first simultaneously, major part implantation body all needs to penetrate cortical bone and hammers in upper and lower jawbone diaphysis, and upper mandibular bone and contiguous organ-tissue complex structure thereof, show shallow, in implantation body's implantation process, easily injure adjacent teeth root of the tooth, wear maxillary sinus by mistake, injure the additional damage such as inferior alveolar nerve; Moreover jawbone cortex is hard, in implantation body's implantation process, there is the probability that implantation body fractures; Further, in implant operation process likely by epithelial tissue band to the marrow in, the risk of tangible one-tenth cyst at a specified future date.
Utility model content
The purpose of this utility model is to provide a kind of Zhi Kangti used in mouth cavity orthodontic process, and it is easy to use, and anchorage reliable effect is effective, and the multinomial shortcoming of implant anchorage can be avoided not enough.
A kind of mouth cavity orthodontic of this utility model Zhi Kangti is the moulding object using metal material to make, and is adhered to the selected position of up/down jawbone, plays anchorage effect when correction during use.A kind of mouth cavity orthodontic of this utility model props up antibody population as a drawing pin shape, comprises base and traction stake two parts.Wherein, base is as inverted dish type, and card down, is tried to get to the heart of a matter upward.The seating plane being equivalent to card is called base end face, and the seating plane being equivalent to try to get to the heart of a matter is called submounts; Base end face is plane, and pedestal edge edge is belittled, and middle part is abundant, and submounts forms the domatic of 5-15 degree from edge part to central part; Submounts central part is a platform, and platform central is provided with screw, and screw inwall is provided with female thread.The shape of the platform of submounts central part is suitable for cylindrical or truncated cone-shaped.Alleged its section cylindrical is rectangle, and its section of alleged truncated cone-shaped is trapezoidal.The longitudinal axis of platform is vertical with base end face.
The traction stake part of this utility model mouth cavity orthodontic Zhi Kangti is a cylindrical bar, and the platform of the lower end and base of drawing stake is in a state of use connected, traction stake and base end face perpendicular.The diameter of traction stake is equivalent to the diameter of base platform upper end, or smaller compared with the diameter of platform upper end; Traction stake lower end is provided with external screw thread, and the traction external screw thread of stake lower end and the female thread of chassis platform adapt.The external screw thread drawing stake lower end during use combines with the female thread of chassis platform and fixedly becomes a complete Zhi Kangti.
As optimization, base end face is provided with reticulate pattern, and when this reticulate pattern is conducive to carrying out bonding, bonding agent embeds, and increases adhesive strength.
As optimization, a cap-like structure is set up on traction stake top, and making traction stake is totally T-shaped structure.This T-shaped structure is convenient to be tied when mouth cavity orthodontic the rubber chain being used as to draw, and keeps rubber chain not come off.
The using method of this utility model mouth cavity orthodontic Zhi Kangti is adhered on up/down jawbone by Zhi Kangti base after surgical exposure up/down jawbone.Adhesive glue selects the α-BCA of medicinal extensive use.This medical adhesive can be solidified by the mode of anionic polymerisation in wet condition, reaches adhesive effect, safe and reliable.Bonding rear to suturing soft tissue, protection base does not loosen by external force.Through certain time, periosteum to be creeped growth along submounts, forms new bone, gradually by fixing for base embedding from periphery to central part.The growth of platform to periosteum of submounts plays certain inhibition, and therefore, the screw on base platform can not be closed by periosteum.By bolt, traction stake is installed on base platform again after base is firm, becomes the Zhi Kangti of a reliable in function.
This utility model mouth cavity orthodontic Zhi Kangti be by medical adhesive at the bonding specific device of bone surface, do not need to invade in bone as implantation body, therefore can evade the operation risk of implant anchorage.
Measure this utility model mouth cavity orthodontic Zhi Kangti maximum load power through zoopery, after surgery at once, 2 weeks, 4 weeks, 8 weeks groups, bone convered structure anchorage maximum load strength mean value is respectively 10.84
+2.85N (1106
+291g), 6.23
+4.50N (636
+459g), 1.80
+1.90N (184
+194g), 45.69
+25.45N(4622
+2597g).Clinical slight Orthodontic force is at below 60g, and moderate power is at 60 ~ 350g.Therefore, can think that bone bonding the antibody capable organized for postoperative 8 weeks meets the fundamental need of orthodontic power.Wherein, postoperative 8 weeks group maximum load intensity can meet all orthodontic power needs.
