Abstract
This utility model relates to a kind of implantation body implantation drill bit, comprise the connecting rod for connecting dental handpiece and be arranged on the bit head of connecting rod front end, the length of described bit head is matched with different implantation body, limiting section is provided with between described bit head and connecting rod, described limiting section is connected with ladder between bit head, and the diameter of limiting section is greater than the diameter of bit head, described limiting section is connected by rake with connecting rod.This utility model is by the improvement to drill bit structure, by the length of the independent design specialized of implantation body's specification, without the need to perusal when piercing, as long as till when when piercing, sensation cannot pierce, can complete, simple to operation, controls science.
Description
Technical field
This utility model relates to a kind of drill bit for dentistry.
Background technology
Implantation body is also called tooth implant, is also called artificial tooth root.Be by operating mode by the upper mandibular bone at its implant into body agomphosis position, after its operation wound heal, the device repairing artificial tooth be installed at an upper portion thereof, generally have bone contour cultivation body and soft tissue contour cultivation body.When it is implanted, need to rely on drill bit, drill bit is detachably attached on dental handpiece, and dissimilar drill bit is replaceable, but time in the degree of depth, for different implantation body, there is different depth requirement, in prior art, different depth still adopts identical drill bit, and drill bit is carried out the respective depth labelling of each implantation body's specification, pierce the degree of depth and control difficulty by perusal, troublesome poeration.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, this utility model provides during a kind of piercing and observes the degree of depth, a kind of implantation body implantation drill bit simple to operation without the need to meatball.
The technical scheme in the invention for solving the technical problem is:
A kind of implantation body implantation drill bit, comprise the connecting rod for connecting dental handpiece and be arranged on the bit head of connecting rod front end, the length of described bit head is matched with different implantation body, limiting section is provided with between described bit head and connecting rod, described limiting section is connected with ladder between bit head, and the diameter of limiting section is greater than the diameter of bit head, described limiting section is connected by rake with connecting rod.
As preferably, bit head is surrounded with blade, is formed with blade groove between blade, described blade groove extends to limiting section.
As preferably, the angle of inclination of rake is 45 °.
As preferably, bit head top is provided with tip, and the angle at described tip is obtuse angle.
As preferably, the ladder height of limiting section is greater than 0.4mm.
The length of bit head is arranged to different length according to different implantation body, then during corresponding different implantation body, as long as more bit change.Limiting section is set between bit head and connecting rod, is used for controlling bit depth, when the degree of depth arrives limiting section, just cannot pierce again, then when piercing, without the need to perusal, as long as till when feeling to pierce, can complete, simple to operation.Be connected by rake between limiting section with connecting rod, and the angle of inclination of rake is set to 45 °.Bit head is surrounded with blade, is formed with blade groove between blade, blade groove extends to limiting section.
The beneficial effects of the utility model are: this utility model passes through the improvement to drill bit structure, by the length of the independent design specialized of implantation body's specification, without the need to perusal when piercing, as long as till when when piercing, sensation cannot pierce, can complete, simple to operation, control science.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, a kind of implantation body implantation drill bit, comprise for connecting the connecting rod 4 of dental handpiece and being arranged on the bit head 1 of connecting rod front end, the length of bit head 1 is matched with different implantation body, be provided with limiting section 3 between described bit head 1 and connecting rod 4, between limiting section 3 with bit head 1, ladder is connected, and the diameter of limiting section is greater than the diameter of bit head, described limiting section is connected by rake 5 with connecting rod, and the angle of inclination of rake is 45 °.Bit head is surrounded with blade, is formed with blade groove 2 between blade, described blade groove 2 extends to limiting section.
Bit head top is provided with tip, and the angle at described tip is obtuse angle.The ladder height of limiting section is greater than 0.4mm.
The length of bit head 1 is arranged to different length according to different implantation body, then during corresponding different implantation body, as long as more bit change.Limiting section 3 is set between bit head and connecting rod, is used for controlling bit depth, when the degree of depth arrives limiting section, just cannot pierce again, then when piercing, without the need to perusal, as long as till when feeling to pierce, can complete, simple to operation.Be connected by rake 5 between limiting section with connecting rod, and the angle of inclination of rake is set to 45 °.Bit head is surrounded with blade, is formed with blade groove between blade, blade groove extends to limiting section.
This utility model is by the improvement to drill bit structure, by the length of the independent design specialized of implantation body's specification, without the need to perusal when piercing, as long as till when when piercing, sensation cannot pierce, can complete, simple to operation, controls science.
