The ultrasonic bone knife head comprises a connector, a knife bar and a knife body, wherein the connector is connected with a handle; the knife body is positioned at the front end of the knife bar and comprises a neck part and sub-roots; the sub-roots gradually contract from the neck part to the root tip; the contour line of each sub-root is a smooth curved line; the sub-roots are bent in the shape of a natural tooth root; the sub-roots are completely covered by the neck part in the overlook direction; and an emery layer for cutting alveolar bone is spray-coated on the outer surface of each sub-root part. According to the ultrasonic bone knife, an irregularly-shaped hole similar to the natural tooth root can be prepared so as to implant an artificial implant similar to the natural tooth root, and the ultrasonic bone knife has the advantages of preventing nerves from being injured, avoiding bone burn during hole preparation and the like.

Description

The piezosurgery osteotomy cutter head that is used for implantation of tooth
Technical field
The present invention relates to a kind of piezosurgery osteotomy cutter head that is used for implantation of tooth.
Background technology
In the selection of anodontia repair mode, the repair mode of tooth plantation is more and more welcome.Compare with traditional repair mode, the repair mode of tooth plantation has maintenance good, and the more traditional artificial tooth of masticatory efficiency is improved largely, and is beautiful and comfortable, and no foreign body sensation does not damage the advantages such as tooth of closing on.
Traditional tooth Implant Prosthesis mode comprises following period: at first needs 3 are waited for knitting to treatment in 12 months after the exodontia.Then, get out a hole at original exodontia nest place, a traditional screw-like or cylindric implantation body are implanted in the hole that gets out in advance with drill bit.At last, implantation body forms synosteosis after implanting some months, opens gingiva artificial artificial tooth is fixed in the implantation body.This type of implantation body's major part is a titanium alloy, is processed into screw-like or cylindric, obtains through surface treatment again.This implantation body is for producing in batches, and shape is single, and has very big-difference with the shape of natural root of the tooth, well the characteristic of the interlock of simulating nature tooth and conductance.
Carry out the tooth Implant Prosthesis, just need get the hole in advance ready at the alveolar bone place, the existing hole mode that is equipped with all adopts machine bit directly to hole at alveolar bone agomphosis place.This hole mode that is equipped with can't prepare profiled holes, also may soft tissue injury, and the big photograph of heat production becomes temperature too high.
Announced a kind of ultrasonic bone cutting device Chinese patent ZL98206710.0 number, comprised main frame and handle amount part, main frame comprises signal generator and power amplifier.Handle is made up of the transducer that is in turn connected to form one, horn and cutter, and transducer is made up of one group of longitudinal polarization piezoelectric patches, and cutter end cutter tooth adopts upright sword formula structure.Power supply links to each other with transducer, makes transducer produce the vibration of single longitudinal ultrasonic and passes to cutter end cutter tooth through horn, implements the skeleton cutting operation.This ultrasonic bone cutting device has higher safety and accuracy, and ultrasonic deep, cutter does not have high speed rotating, does not have other not shaking, effectively neuroprotective and blood vessel, thereby be widely used in spinal surgery, neurosurgery, department of otorhinolaryngology and plastic surgery.But, also this ultrasound wave cutter is not applied to be used in the implantation of tooth prepare the profiled holes similar with natural tooth root at present.
Summary of the invention
For directly big in the implantation of tooth that overcomes in the osseous tissue wound that alveolar bone boring causes with drill bit; Heat production cause greatly temperature too high with can't prepare the shortcoming of profiled holes, can appearance temperature when the invention provides a kind of, boring little not too high and can prepare the piezosurgery osteotomy cutter head that is used for implantation of tooth of profiled holes to the osseous tissue damage.
The piezosurgery osteotomy cutter head that is used for implantation of tooth; Comprise union joint, knife bar that is connected with handle and the cutter hub that is positioned at the knife bar front end, cutter hub comprises cervical region and daughter root, daughter root from cervical region to tip of a root convergent; The contour line of each daughter root is level and smooth curve, and the daughter root bending is nature root of the tooth shape; Cervical region covers daughter root fully overlooking on the direction, the outer surface of each daughter root portion all is coated with the Buddha's warrior attendant layer of sand that is used to cut alveolar bone.
Further, the quantity of daughter root is 2-3, and side by side, cervical region covers all daughter root fully overlooking on the direction between the daughter root.
Further, the cutter hub cervical region is cylinder or oval cylinder; The cutter hub cervical region has the guiding fin that parallels to the axis, and the gathering sill of guiding die plate is adaptive when guiding fin and plantation.
Further, the cutter hub top is provided with outward extending flange, the planting depth of the shoulder height decision implantation body of the plantation guide plate that adopts in the implantation of tooth, and the flange contact contacts the degree of depth that then expression reaches implantation body with step surface.
Further, the cervical region of cutter hub is provided with the graduation mark that sign is equipped with hole depth.
Further, knife bar and handle are through being threaded.Handle is provided with external screw thread, and knife bar is provided with the female thread with the engagement of handle external screw thread.Knife bar is with after handle is connected, and dither is passed to knife bar and cutter hub from handle.
Further, union joint and knife bar connecting portion are through round-corner transition, and the diameter of knife bar is less than the diameter of union joint.
Further, knife bar is a bent rod, and sweep is convenient in the oral cavity, be equipped with hole operation.
Further, there is psychrophore cutter head inside, can play the effect of logical cooling water.
Technical conceive of the present invention is: the cross section of cutter hub cervical region is maximum, the cutter hub root from cervical region to the daughter root convergent, to guarantee to be equipped with the feasibility in hole at alveolar bone.Cutter hub is processed nature root of the tooth shape, and the Buddha's warrior attendant layer of sand through the cutter hub outer surface cuts alveolar bone, the plan nature tooth implant of the corresponding a kind of model of each osteotome.The present invention can prepare the plantation nest adaptive with natural root of the tooth on alveolar bone, thereby makes that implantation body becomes possibility like manufacturing and use and the natural thread form.
Be equipped with the hole with provided by the invention with the implantation body similar piezosurgery osteotomy of implant part shape.Ultrasound wave is after transmitting, and cutter hub produces the high-frequency microwave vibration, continues bump osseous tissue intermittently, thereby crashes and remove osseous tissue.Utilize piezosurgery osteotomy to undergo surgery and more help early stage knitting, safer accurate, better control cellular inflammation, promote osteogenesis and reconstruction.
This piezosurgery osteotomy adopts cold cut to cut pattern, and the cooling water ejection is arranged in the endoporus of cutter head in cutting process, and a large amount of water smoke cooling of cavitation effect generation occurs through the vibration of cutter head, and heat production is few, cutting zone form rule, and the cutting border is accurate.Utilize piezosurgery osteotomy to undergo surgery and more help early stage knitting, safer accurate, better control cellular inflammation, promote osteogenesis and reconstruction.
The present invention can prepare the profiled holes similar with natural root of the tooth so that implant the artificial growth body similar with natural root of the tooth, and can avoid nerve injury, can not occur bone advantage such as burn during the hole fully.
