Abstract
The invention relates to a defected-tooth implanting or restoring technology, in particular to a spline-tooth type oral implanting device comprising an implanting body, a base station and fastening bolts. External threads are arranged on the implanting body, and stepped cylindrical-surface inner cavity is arranged in the implanting body; the lower end of the base station is provided with a tubularconnecting handle which is connected with the implanting body. The spline-tooth type oral implanting device is characterized in that the connecting handle and an inner cylindrical surface through which the implanting body and the base station are connected are provided with matchable spline teeth, and the lower part of the implanting body is provided with a longitudinal cut groove is deeper thanthe threads. The spline-tooth type oral implanting device can be operated conveniently and can be well combined with the alveolar bone; the implanting body has good stability and can bear larger torque without being internally deformed; the base station and the implanting body can be adjusted in angle and can be connected in high precision; and the spline-tooth type oral implanting device can reduce the bone resorption.
Description
Technical field:
The present invention relates to plantation or recovery technique field behind the tooth defect, specifically a kind of spline-tooth type oral implanting device.
Background technology:
The sixties in 20th century, Sweden Gothenburg university
Professor has carried out about tooth-planting material and bone--implantation body's Study of Interface, founded " synosteosis " theory of titanium, for theoretical basis has been established in the application of modern oral implantology, the tooth-planting application technology is a most important part in the modern oral implantology.Extensively the carrying out and use the problem that has solved on a series of attractive in appearance and function that absence of tooth clinically brings of tooth-planting artificial tooth.
Yet implantation body is in planting process, because the hypodontia space is narrow and small, the operation technique difficulty is big because this body structure of implantation body and factors such as sclerotin and the operation primary stability after causing planting is poor, with some desirable not to the utmost parts are also arranged cooperating of superstructure.Often run into three problems, the one, because implantation body adopts screw shape and screw-in plantation, when in implantation body's planting process, reaching later reparation, implantation body can cause the inner local deformation that produces because of bearing moment of torsion, this makes meets difficulty when base station is in place, also may make between base station and implantation body to produce loosening or diastema is arranged; The 2nd, bone extruding degree is difficult to hold, and excessive extrusion can occur or not have the gapped situation of extruding; The 3rd, plantation is repaired the back bone resorption is easily taken place, and these all may cause planting the undesirable or repairing failure of repairing effect.
Summary of the invention:
Purpose of the present invention is exactly in order to overcome above-mentioned the deficiencies in the prior art, provide a kind of anti-rotate effect good, can bear high pulling torque more, combine effective, easy to operate, good stability with alveolar bone, can reduce the spline-tooth type oral implanting device of bone resorption.
The present invention can reach by following measure:
A kind of spline-tooth type oral implanting device, comprise implantation body, base station and fastening bolt, implantation body is provided with external screw thread, be provided with ladder face of cylinder inner chamber in the implantation body, the base station lower end is provided with the tubulose connection handle that is connected with implantation body, base station is connected with implantation body through fastening bolt, it is characterized in that the inner cylinder that implantation body is connected with base station is provided with key tooth and the keyway that matches with connection handle, and the implantation body bottom is provided with the straight-cut groove above the depth of thread.
Implantation body of the present invention is the bigger micro taper body of cylindricality recess diameter, external screw thread indentation in the implantation body, the external screw thread of cervical region is upwards gradually shallow to disappearing, the external screw thread degree of depth of remainder is identical, can produce the bone squeezing effect of appropriateness, improve the primary stability of operation, make implantation body and alveolar bone better combine, improve plantation later stage synosteosis stability and result of use.
The key tooth that implantation body's inner cylinder matches with connection handle among the present invention generally is provided with in the cervical region of implantation body, and quantity is 2-6, generally is provided with 4 key teeth and cooperates with base station, accurately being that anti-spinfunction is circumferentially located and provided to base station.
Keyway number among the present invention on the base station connection handle is the integral multiple of the protruding bond number of implantation body, to regulate the relative angle of base station and implantation body, makes things convenient for operation technique, improves plantation quality and result of use.
Keyway upper end semicircular in shape among the present invention on the base station connection handle, lower end flare opening shape is installed and the dismounting base station with convenient, makes its more convenient operation.
Cutting slot of the present invention is bottom-up gradually shallowly to disappear to the middle part, so that make implantation body's self tapping insert in the alveolar bone and increase implantation body and the bonded fastness of alveolar bone.
Implantation body of the present invention diameter becomes seriation with length, have different diameters and length available, and the connection handle of base station is unified, can cooperate any one implantation body in the series.When being used for the base station of small dimension in the large diameter implantation body, the counterface one little of base station and implantation body is big, and implantation body is big, and in this case, alveolar bone will be left in the land of base station and implantation body's end face, and this can reduce or be avoided the generation of bone resorption.
That the present invention has is easy to operate, bear more high pulling torque with alveolar bone in conjunction with effective, plantation physical ability and can not produce internal modification, good stability, base station and implantation body adjustable angle joint, base station and be connected the precision height with implantation body, also can reduce advantage such as bone suction.
