Abstract

The utility model discloses a minimally invasive extraction buried multi-raw-tooth intraoperative positioner, which comprises a tooth plaster model, wherein a plurality of to-be-marked objects grow in the tooth plaster model, a scale is arranged at the upper end of the tooth plaster model and is in a metal grid shape, and the scale covers the to-be-marked objects; and the upper end of the scale is provided with a positioner. The utility model discloses can more accurately guide position, the form of many raw teeth in bone tissue in the art, especially the widest department of many raw teeth dental crown, pull out the in-process and can be still less get rid of bone tissue, protect young permanent tooth and the nasal palate nerve, simultaneously, can carry out accurate location to many raw teeth in the operation process, and then can be still less get rid of bone tissue, protect young permanent tooth and nasal palate nerve.

Description

Positioner for minimally invasive extraction and embedding multi-dental implant operation

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a positioner in many living tooth art of embedding is pulled out to wicresoft.

Background

More raw teeth, an oral disease caused by abnormal tooth form and number in the process of tooth germ formation, is more than 20 deciduous teeth or 32 permanent teeth. Multiple raw teeth the most common of the more raw teeth in the maxillary centre, which may be single-shot or multiple-shot, is mostly inverted in the growth direction within the jaw. The occurrence of multiple raw teeth can cause various malocclusion deformities on the jaw face, including too wide dentition gaps, crowded dentition, late eruption and malposition of permanent teeth, growth arrest and the like, so that the multiple raw teeth can be discovered early and extracted as early as possible through an operation. Diagnosis before the art mainly relies on curved surface fault slice or CBCT to advance line location to many raw teeth, based on this the utility model provides a locator in the art can more accurately guide many raw teeth position, form in bone tissue in the art, can be less removing bone tissue, protection adjacent permanent tooth and nose palatal nerve removing the in-process.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a positioner in many teething art of wicresoft's extirpation buried is provided, solves the problem of many teething location.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model relates to a positioner in minimally invasive extraction buried multi-raw tooth surgery, which comprises a tooth plaster model, wherein a plurality of to-be-marked objects grow in the tooth plaster model, a scale is arranged at the upper end of the tooth plaster model and is in a metal grid shape, and the scale covers the to-be-marked objects; and the upper end of the scale is provided with a positioner.

Further, the positioner comprises a film pressing part applied to the upper end of the scale, a retaining part is integrally formed on the outer half periphery of the film pressing part, and the retaining part is inversely buckled on the teeth of the tooth plaster model.

Further, a number of the markers include multiple raw teeth, adjacent young permanent teeth, and nasopalatine nerves.

Further, the material of the positioner is transparent PVC.

Furthermore, the thickness of the positioner is 0.8-2 mm.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses a positioner is in the in-process that uses in the type wicresoft pulls out many raw toothings of prostrate, the patient wears the positioner, many raw teeth, adjacent young permanent tooth, nasal palatine nerve and metal mesh can develop on X-ray film, can measure many raw teeth of distance effectively through this three-dimensional CT of CBCT, nearest body surface position, the upper jaw bone outside cortex lycii promptly, we just can mark out on the metal mesh, can more accurately point out the position of many raw teeth in the bone tissue in the art, the form, especially the widest department of many raw teeth dental crown, can be less get rid of bone tissue in the process of pulling out, protection young permanent tooth and nasal palatine nerve, and simultaneously, can carry out accurate location to many raw teeth in the operation process, and then can be less get rid of bone tissue, protection young permanent tooth and nasal palatine nerve.

Detailed Description

As shown in fig. 1-4, a minimally invasive extraction and implantation positioner in multi-raw tooth surgery comprises a tooth plaster model 1, wherein a plurality of objects to be marked 4 grow in the tooth plaster model 1, and a plurality of objects to be marked 4 comprise multiple raw teeth, adjacent young permanent teeth and nasopalatine nerves.

The scale 2 is installed to tooth gypsum model 1 upper end, and scale 2 covers in the gypsum model surface, is connected or laminates with transparent PVC membrane. The scale 2 is in a metal grid shape, and in this embodiment, the scale 2 is a metal mesh with a side length of 5 mm. The scale 2 covers a plurality of the objects 4 to be marked and is used for assisting CBCT projection detection.

The upper end of the scale 2 is provided with a positioner 3, the positioner 3 comprises a film pressing part 3-2 applied to the upper end of the scale 2, a holding part 3-1 is integrally formed on the outer half periphery of the film pressing part 3-2, and the holding part 3-1 is reversely buckled on teeth of the tooth plaster model 1. In the embodiment, the positioner 3 is made of transparent PVC, the thickness of the positioner is 0.8-2 mm, and the scale 2 is connected or attached to the transparent PVC film.

The action process of the utility model is as follows:

firstly, preparing a plaster model of the oral cavity of a patient; placing the scale on the maxillary and palatal sides of multiple raw teeth so that the scale is fixed on the positioner, and pressing a film on the tooth model by a film pressing machine to finish the required shape; then, the patient wears the positioner; finally, CBCT examination is carried out, projections of multiple raw teeth, adjacent young permanent teeth and nasal and palatine nerves are marked (positioned on a positioner through CBCT and a ruler), the body surface part which is closest to the multiple raw teeth, namely the maxillary bone outermost cortical bone is effectively measured, and the projections are marked on the positioner, and the shape is trimmed and used for later use in the operation.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
