Abstract

The invention discloses an assist device for tooth extraction which mainly comprises a high frequency vibrating tool bit driven by ultrasonic wave. The tool bit accords with tooth anatomical morphology and has a front chiseling edge or/and a side scraping edge. This tool bit utilizes high frequency oscillation provided by an ultrasonic host to make the ultrasonic tool bit move back and forth at high speed[w1], thus to facilitate the cutting of periodontal ligaments by the tool bit and to loose teeth through high frequency oscillation.

Description

Tooth extraction aid

Technical field

The present invention relates to exodontia equipment, be meant a kind of tooth extraction aid especially with ultrasound cutter.

Background technology

In the tradition dental implant surgical, tooth implantation technology still during immaturity immediately after the exodontia, organize between recovery period in wait exodontia wound soft or hard, for avoiding the alveolar bone atrophy, influence is following plants the success rate of tooth and attractive in appearance, develop and a lot of technology to reduce alveolar bone atrophy amount, the most normal use is to insert bone meal or collagen protein after the exodontia immediately to keep the space, handle the surface and design is become better and better but along with planting, the success rate of planting tooth after the exodontia immediately also improves thereupon, following in many effort researchs of planting tooth older generation doctor, planting tooth immediately becomes the prevailing model of planting the tooth selection of time after the exodontia gradually.

What plant immediately after the exodontia that tooth directly faces is exactly how to keep best alveolar bone state in the exodontia process; the tradition exodontia is to utilize root elevator to insert in the periodontal membrane of root of the tooth; use wedge (chock) strength that root of the tooth and alveolar bone are got loose; or utilize lever principle that root of the tooth is ejected; no matter be wedge (chock) or lever principle; more or less all can produce and destroy alveolar bone; especially root of the tooth cheek side place; generally speaking the cheek side alveolar bone of root of the tooth is all extremely thin; be thinned to surplus a slice hone lamella; especially more obvious with the top labial teeth, pull out root of the tooth in tradition exodontia mode and usually can stave this piece hone lamella, cause the success rate of planting tooth immediately to descend and the influence attractive in appearance of following artificial tooth.

Alveolar bone is destroyed on every side in order to prevent root of the tooth, so Periotome (periodontal chisel) (periodontal chisel) exodontia mode is devised, Periotome (periodontal chisel) is an extremely thin apparatus, be thinned in the periodontal membrane that can insert root of the tooth, re-using the surgery mallet raps, Periotome (periodontal chisel) is goed deep into periodontal membrane gradually, cut off the binding (periodontal ligament) of root of the tooth and alveolar bone thus, along root of the tooth all around the high and low cut a circle, be separable root of the tooth and alveolar bone, just can take out root of the tooth at last and can not destroy alveolar bone, non-invasive exodontia (Atraumatic Tooth Extraction) that Here it is, the non-invasive of Periotome (periodontal chisel) are had tooth pulled out and are planted the simplicity and the success rate of tooth after raising is had tooth pulled out greatly immediately.

Periotome (periodontal chisel) is handy really a lot of compared with traditional root elevator, but finds to have following problem in clinical practice:

Periotome (periodontal chisel) not abscission ring root of the tooth and beats up and down to cut off the periodontal ligament around the root of the tooth, bothers very much and wastes time and energy.

Except that labial teeth, the backteeth zone usually is limited by patient's opening problem and is difficult to operation.

Periotome (periodontal chisel) Chang Bixu utilizes the surgery mallet to knock in the periodontal ligament, and is often improper or beat wrong court because of the application of force for the abecedarian, thereby causes hone lamella to break to become traumatic exodontia on the contrary.

Periotome (periodontal chisel) is designed to a collinear thin slice, but in fact a lot of roots of the tooth are not linear type, but draw in to the tip of a root with curve gradually at a place of two minutes of root of the tooth, so when using the periodontal ligament of Periotome (periodontal chisel) incisor roots, seldom be really to switch at the bottom of the root of the tooth fully, be to switch to a place of three minutes of apex of root of tooth mostly, even so can find to use Periotome (periodontal chisel) after, root of the tooth is obviously not loosening, also needs root elevator to give some lever strength sometimes and tears remaining periodontal membrane tissue.

Periotome (periodontal chisel) just cuts off periodontal ligament in fact, does not do loose root of the tooth simultaneously, therefore also needs other instruments (as Elevator) to do loose undesirable root, but has slight curvature or position very dark in case run into undesirable root, is difficult for sometimes taking out.

In addition, undesirable root after the root canal is very easy to cracked, one side exodontia one side is cracked to be very common thing, and to the undesirable root of the surplus alveolar bone deep layer of nuzzling only, this class root of the tooth cuts off periodontal ligament by Periotome (periodontal chisel) merely and still is difficult to taking-up sometimes through normal off.
