Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to root canal therapy of molar opens marrow baffle.
Background
Through the research of stomatology in 20 th, 30 th and 40 th hospitals, designers find that the root canal treatment of molar is always a difficult problem of oral treatment due to high technical requirements and complex operation, and the marrow finding of root canal orifices is a key step of the treatment. For a long time, the traditional marrow opening method is adopted for tooth marrow opening during molar root canal treatment, and because many doctors are unfamiliar with tooth anatomy and cannot find the root canal orifice after the marrow opening, the range of the marrow opening is enlarged blindly, the tooth injury is too large, the treatment time of the doctors is too long, and the treatment effect of patients is poor. Severe cases may cause the teeth to be fractured and pulled out.
SUMMERY OF THE UTILITY MODEL
In view of the above circumstances, in order to solve the problems of the above-mentioned techniques, the present invention provides a endodontic opening guide for molar use, which can conveniently search for the root canal orifice and minimize the damage to the teeth.
A marrow opening guide plate for molar root canal therapy comprises a jaw face portion, a cheek side portion and a palate side portion, wherein a marrow cavity shape hole is formed in the middle of the jaw face portion, the cheek side portion is arranged on one side of the jaw face portion, and the palate side portion is arranged on the other side of the jaw face portion. The medullary cavity shape hole is provided with a medullary opening point corresponding to the root canal orifice.
According to the pulp opening guide plate for the root canal therapy of the molar, the jaw part is a corrugated structure which is matched with the shape of the upper surface of the molar crown.
According to the dental root canal treatment pulp opening guide plate for the molar teeth, the maxillofacial part, the cheek side part and the palate side part are combined to form a semi-crown-shaped structure.
After the technology provided by the utility model is adopted, the marrow opening guide plate for the root canal therapy of molar has the following beneficial effects.
1) The guide plate is designed in a semi-crown shape (cheek and palate side), and is made of a polyethylene material which is light, transparent, non-toxic and elastic to a certain extent; the guide plate is designed into a half crown shape according to the physiological and anatomical characteristics of the molar crown and the pulp cavity, the cheek side and the palate side can clamp and hold the crown, the jaw-face hollow shape is the shape of the molar pulp cavity, and the corresponding pulp opening position is the position of the rhizosphere opening. The root canal opening is very easy to find, thereby effectively solving the difficulty of the root canal treatment of molar, shortening the treatment time of doctors, improving the treatment effect, preserving the affected teeth to the maximum extent and reducing the pain of patients.
Drawings
Fig. 1 shows a view of a pulp opening guide for endodontic treatment of molar according to the present invention.
Detailed Description
Various preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to assist in understanding the exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist understanding, but they are to be construed as merely illustrative. Accordingly, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Also, in order to make the description clearer and simpler, a detailed description of functions and configurations well known in the art will be omitted.
As shown in figure 1, the marrow opening guide plate for the root canal treatment of the molar comprises a jaw part 1, a cheek part 2 and a palate part 3, wherein the middle part of the jaw part 1 is provided with a marrow cavity form hole 4, the cheek part 2 is arranged on one side of the jaw part 1, and the palate part 3 is arranged on the other side of the jaw part 1. The medullary cavity shape hole 4 is provided with a medullary opening point 5 corresponding to the root canal orifice.
The jaw part 1 is a corrugated structure matched with the shape of the upper surface of the ground dental crown.
The jaw 1, the cheek 2 and the palate 3 form a semi-crown-shaped structure in combination.
According to the guide plate for the open-pulp treatment of the root canal of the molar tooth, the guide plate is designed into a half crown shape according to physiological and anatomical characteristics of a molar tooth crown and a pulp cavity, the tooth crown can be clamped and clasped by cheek and palate sides, the hollow form of the jaw face is the form of the pulp cavity of the molar tooth, and the position corresponding to the open-pulp point is the position of a rhizosphere opening.
The marrow opening guide plate for the root canal therapy of the molar is prefabricated according to the specific anatomical forms of upper and lower molar teeth, can be clamped and fixed on a tooth crown, the hollow form of the maxillofacial surface is the form of a marrow cavity, and the corresponding position of the marrow opening point is the position of a root canal opening. The root canal opening is very convenient to find, and the damage to the teeth is reduced to the maximum extent.
The pulp opening guide plate for the root canal therapy of molar teeth is disposable and can be made into series products. According to the international classification: 1 represents the right upper jaw tooth; 2 represents the left upper jaw tooth; 3 represents the left lower jaw teeth; and 4 represents the right lower jaw teeth. The number of the molar crown is 1-6 from small to large. According to this rule, the guides marked (11-16) are adapted to the small to large right upper molar; the guide plates marked (21-26) are adapted to the small to large left upper jaw molars; the guide plates marked (31-36) are adapted to the small to large left mandibular molar; the guide plates marked (41-46) accommodate small to large right mandibular molars.
According to the utility model provides a marrow baffle is opened in root canal therapy of molar, beneficial effect lies in: the guide plate is designed in a semi-crown shape (cheek and palate side), and is made of a polyethylene material which is light, transparent, non-toxic and elastic to a certain extent; the guide plate is designed into a half crown shape according to the physiological and anatomical characteristics of the molar crown and the pulp cavity, the cheek side and the palate side can clamp and hold the crown, the jaw-face hollow shape is the shape of the molar pulp cavity, and the corresponding pulp opening position is the position of the rhizosphere opening. The root canal opening is very easy to find, thereby effectively solving the difficulty of the root canal treatment of molar, shortening the treatment time of doctors, improving the treatment effect, preserving the affected teeth to the maximum extent and reducing the pain of patients.
