Description
Technical field
The present invention relates to a kind of medicine equipment, more particularly to a kind of planting body central screw fracture residue brill
Spacing stabilizer when taking.
Background technology
Tooth implant is implanted into after human body alveolar process or jawbone, is acted on by the Integrated implant of certain time, plantation
The cortex of body root surface and bone tissue is ossified to make implant and bon e formation be difficult to the entirety separated, i.e. synosteosis
State.
And combined type dental implant system is mainly made up of following three part-structure：1. planting body root, i.e.,
Heeling-in turns into the foundation part of tooth-implanting in alveolar process or jawbone bone tissue；2. planting body top base station,
Connect and fix various forms of coronas or the effect of other dummies；3. the central connecting rod of planting body is (i.e.
Planting body center screw follow closely), bar portion pass through base station hollow region, screw thread by planting body top base station bolt/
Fixed/to be tightly locked in planting body root ,/inseparable an entirety can not be loosened by becoming.
During Clinical practice, there are two kinds of situations to cause the central screw fracture for fixing planting matrix platform：
1st, in the operating process for installing planting body top base station, torque is excessive during due to reinforcing causes central fixation
Screw fractures；2nd, the formation synostosis time is longer between combined type root shape planting body and bone, and its top is matched somebody with somebody
Set base station and corona are connected as one formula implant denture after being fixed by the thinner central screw of diameter, when
When it exercises masticatory function, after the shearing jaw power effect by long-term repeatedly iterative cycles, central screw gold
Category produces fatigue, and central screw body portion may be caused to be broken.
Clinically no matter which kind of reason causes tooth-implanting base station and the interface unit of planting body root to fracture, i.e.,
Central maintenance rivet nut portion fractures, and its Remained mass is difficult to adopt simple derotation in the rivet nut portion for taking root in body center
Shifting method takes out, and is fractureed especially with the screw after the binding agent of enhancing Screw retained effect, is even more
Simply it can not possibly take out or change.Now the bonding state of planting body and bone tissue is good, or reaches completely
To synostosis state, central screw Remained mass is taken out, the screw more renewed can use its regeneration,
A mouthful transluminal operation then can be clinically carried out to drill through Remained mass and attack again to planting root medium pore of taking root
Silk.
Under normal circumstances, the material hardness of combined type planting body central screw is high compared with the hardness of planting body material
(billon, titanium alloy etc.), external existing taking-up mode or way use direct using high speed drill
Brill is removed, but hand-held set head tremor throw is big, stability is poor, be easily caused when directly drilling through drill bit displacement and it is inclined
From middle axle position/center of planting body, cause to drill through failure.
The content of the invention
The present invention is intended to provide a kind of planting body central screw fractures, residue drills through spacing stabilizer, uses
When can ensure that the brill point of hand-held high speed drilling tool drill bit in working condition is always positioned at screw section completely
Center, without departing from the axis of tooth implant, ensure cut drill in a kind of relatively-stationary rail
Run and mobile in mark, i.e., the situation of hole scattering does not occur, ensured when drilling through central screw Remained mass not
The body wall of planting body is damaged, is conducive to tapping again, is continuing with planting body.
To reach above-mentioned purpose, the technical solution adopted by the present invention is as follows：
The planting body central screw residue that fractures drills through spacing stabilizer, including clamping part, connecting portion, connects
