Description

Technical Field

[0001] This invention relates to the field of dental treatment tools, and in particular to a hollow-structured electric heating head for gutta-percha. Background Technology

[0002] Root canal filling is a crucial step in root canal treatment, and its quality directly impacts the success rate of the treatment, playing a vital role in preserving the long-term health of the affected tooth. The quality of the filling depends on the effectiveness of coronal and apical sealing, with the sealing of the middle and lower segments of the canal being particularly important. Commonly used root canal filling methods include lateral condensation, thermoplastic gutta-percha filling (intermittent and continuous wave filling), and the single-point method. Each method has its advantages and disadvantages, and clinicians can choose the appropriate method based on the specific circumstances. Thermoplastic gutta-percha continuous wave filling is currently the most commonly used method and is considered the "gold standard." However, this method requires a high level of skill. Currently, when using electrically heated tips to compact and cut the master gutta-percha point and remove the middle and upper segments, overfilling of the master gutta-percha and incomplete removal of the upper and middle segments often occur, necessitating refilling or even causing root canal treatment failure. Summary of the Invention

[0003] The purpose of this invention is to provide a hollow-structured thermoplasticized gutta-percha head to solve the problems existing in the prior art, thereby reducing the difficulty of thermoplasticized gutta-percha root canal filling, improving the accuracy of root canal filling, and reducing the treatment failure rate.

[0004] To achieve the above objectives, the present invention provides the following solution: The present invention provides a hollow-structured thermoplastic heating head, comprising... The working tip includes a head, a body, and a tail that are sequentially and integrally connected. The head is a flat-bottomed solid structure or a conical solid structure. The body is a hollow structure, and an opening is provided on the outer side of the body. The connecting rod has a detachable connection between the tail of the working tip and the connecting rod, and the other end of the connecting rod is connected to the heating device.

[0005] In one embodiment, the length of the head is 2 to 3 mm.

[0006] In one embodiment, the upper part of the solid structure of the head is surrounded by a metal wall.

[0007] In one embodiment, a plurality of openings are symmetrically distributed on both sides of the tube wall of the body along the long axis of the working tip.

[0008] In one embodiment, the number of openings on each side of the tube wall of the body is 8-10, and the openings communicate with the inner cavity of the hollow structure of the body.

[0009] In one embodiment, the diameter of the opening is 0.3-0.5 mm, and the diameter of the opening gradually increases from the head to the tail of the working tip.

[0010] In one embodiment, the drilling direction of the opening is always 45 degrees oblique to the head of the working tip.

[0011] In one embodiment, the tail of the working tip is connected to the first end of the connecting rod by a thread or a snap fastener.

[0012] In one embodiment, the connecting rod is a solid connecting rod.

[0013] The present invention achieves the following beneficial technical effects compared to the prior art: The hollow-structured thermoplastic gutta-percha electric heating tip of this invention includes a detachably connected working tip and a connecting rod. The working tip is divided into three parts: a head, a body, and a tail. The head is a flat-bottomed solid structure or a conical solid structure, the body is a hollow structure with an opening, and the tail is used to connect to the connecting rod. The other end of the connecting rod is connected to a heating device. This invention improves upon the difficulties of current vertical pressure continuous wave obturation of root canals with thermoplastic gutta-percha. The hollow structure provides space for liquid gutta-percha and root canal filling paste, reducing the chance of gutta-percha and root canal filling paste flowing to the apex and reducing the possibility of overfilling. When the working tip of the electric heating tip is pulled outwards, the upper and middle sections of the master gutta-percha point can be completely removed. In summary, this design reduces the difficulty of thermoplastic gutta-percha root canal obturation, improves the accuracy of root canal obturation, and reduces the treatment failure rate.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The purpose of this invention is to provide a hollow-structured thermoplasticized gutta-percha head to solve the problems existing in the prior art, thereby reducing the difficulty of thermoplasticized gutta-percha root canal filling, improving the accuracy of root canal filling, and reducing the treatment failure rate.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-2 As shown, the present invention provides a hollow-structured thermoplastic heating head for gutta-percha, comprising: The working tip includes a head 1, a body 2, and a tail 4 connected in sequence. The head 1 is a flat-bottomed solid structure or a conical solid structure; the body 2 is a hollow structure, and an opening 3 is provided on the outer side of the body 2. The connecting rod 5 has a working tip tail 4 that is detachably connected to it, and the other end of the connecting rod 5 is connected to the heating device.

[0020] In one embodiment, the length of the head 1 is 2-3 mm.

[0021] In one embodiment, the upper part of the solid structure of the head 1 is surrounded by a metal wall.

[0022] In one embodiment, along the long axis of the hollow electric heat-carrying head, 8 to 10 openings 3 are symmetrically and evenly distributed on both sides of the tube wall from the top to the bottom. All openings 3 communicate with the hollow structure inside the working tip of the electric heat-carrying head. The diameter of the openings 3 is about 0.3 to 0.5 mm, with a smaller diameter at the top and a larger diameter at the bottom. The openings 3 are all drilled at a 45-degree angle towards the tip of the working tip.

[0023] The taper and model of the working tip of the hollow thermoplastic heating head are consistent with those of the commonly used thermoplastic heating heads on the market.

[0024] In one embodiment, the working tip of the hollow thermoplastic heating head is connected to the connecting rod of the heating head via threads or snaps at the tail 4 of the working tip. The connecting rod of the heating head is connected to the heating device.

[0025] In one embodiment, the connecting rod 5 is a solid connecting rod.

[0026] Based on the principles of mechanics and fluid mechanics, the hollow structure of the electrically heated tip working tip is designed so that when solid gutta-percha transforms into liquid gutta-percha, the liquid flow changes from the original apical, coronal, and lateral movement along the prepared root canal channel to a multi-directional flow along the apical, coronal, lateral, and hollow structures of the electrically heated tip working tip. The lateral opening 3 provides a channel for liquid gutta-percha to enter the hollow structure inside the working tip. This hollow structure design provides space for the liquid gutta-percha and root canal filling paste, reducing the chance of them flowing towards the apex and minimizing the possibility of overfilling.

[0027] Based on the principles of mechanics and fluid mechanics, the hollow structure of the electrically heated tip is designed so that when the liquid gutta-percha cools and solidifies, the prepared root canal channels—including the apical, coronal, and lateral surfaces, as well as the interior of the hollow structure of the electrically heated tip—are all filled with solid gutta-percha, forming a three-dimensional, homogeneous mass. This reduces the chance and adhesion of the upper and middle sections of the gutta-percha to the root canal walls. As the electrically heated tip is pulled outwards, the upper and middle sections of the master gutta-percha point can be removed intact.

[0028] The electric heating head working tip of the present invention maintains the taper and flat-bottom solid structure of the original heating head working tip, thus maintaining the original electric heating head working tip's vertical heat application function and the function of cutting off the middle and upper section of gutta-percha.

[0029] In summary, the electric heating tip design of the thermoplastic gutta-percha in this invention reduces the difficulty of thermoplastic gutta-percha root canal filling, improves the accuracy of root canal filling, and reduces the treatment failure rate.

[0030] This invention discloses a heated gutta-percha tip with a hollow structure. This tip addresses the overfilling issues of the lower gutta-percha point and the problem of cutting off and removing the upper and middle sections of the main gutta-percha. The tip includes a hollow heated working point with three openings, the number of openings, their size, and their direction. The hollow heated working point forms a gutta-percha reservoir, integrating with the gutta-percha adhered to the prepared root canal wall. The tip has a 2-3mm flat-bottomed solid structure. The tail of the hollow heated working point is connected to the heated head connecting rod via threads or snap-fit, and the connecting rod is connected to the heating device. This method minimizes the overfilling of the main gutta-percha point and paste when the heated working point applies vertical pressure, and solves the problem of cutting off the main gutta-percha point and removing the upper and middle sections of the main gutta-percha after cooling. This simplifies and reduces the difficulty of root canal filling, improves accuracy, and reduces the filling failure rate.

[0031] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
