Technical Field
One or more embodiments of the present invention generally relate to endodontic tools. More particularly, the present invention relates to an endodontic hand file having a shank with an exposed window for attachment of an electronic apex locator.
Background
The following background information may present examples (without limitation, e.g., methods, facts, or common sense) of certain aspects of the prior art that, while intended to assist the reader in further educating the reader about other aspects of the prior art, should not be construed as limiting the present invention or any embodiments thereof to any matter described or suggested or inferred therein.
Referring to fig. 1,
One problem often encountered with conventional
In addition, when a tooth is endodontically treated using a metal crown, the metal shaft of the endodontic hand file may contact the metal restoration, thereby causing a problem of root canal measurement. An insulating sheath may be used to cover the file shaft, but may also limit access to the file shaft in contact with the EAL probe.
In view of the above, there is a need for improved dental instruments to help facilitate the endodontic procedure.

It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
In describing the present invention, it should be understood that a number of techniques and procedures are disclosed. Each of these techniques and steps has its own advantages, and each can also be used in combination with one or more, or in some cases, all, of the other disclosed techniques. Thus, for the sake of clarity, the description will avoid repeating every possible combination of steps in an unnecessary fashion. However, upon reading the specification and claims, it should be understood that such combinations are entirely within the scope of the invention and the claims.
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details.
The present disclosure is to be considered as an example of the invention and is not intended to limit the invention to the particular embodiments shown in the drawings or described below.
As known to those skilled in the art, many careful considerations and compromises must often be made when designing the best configuration for a commercial implementation of any device, particularly embodiments of the present invention. Commercial implementations consistent with the spirit and teachings of the invention may be configured as desired for particular applications, whereby any aspect, feature, function, result, component, method, or step of the teachings related to any described embodiment of the invention may be suitably omitted, included, adapted, mixed and matched, or modified and/or optimized by those skilled in the art using their average and known techniques, to achieve a desired implementation meeting the needs of a particular application.
Broadly, embodiments of the present invention provide a dental instrument designed to help facilitate the process of endodontic treatment. The dental instruments can reduce errors associated with using conventional methods of attaching an Electronic Apex Locator (EAL) to an endodontic hand file. Endodontic hand files may include an exposed window in the handle of the file, which holds an extension of the file body. The clip of the EAL may be connected to exposed metal in the handle window. The new position for attaching the EAL to the hand file can provide accurate measurements while eliminating variables such as file movement in the root canal, plug thickness, clearance from the opposing tooth, etc. Endodontic hand files with exposed windows provide a safe, reliable and accurate method of measuring the length of a root canal using an EAL.

All features disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
The elements and steps of the claims herein may have been numbered and/or underlined for ease of reading and understanding only. Any such numbering and headings are not intended to, and should not be used to, indicate the order of the elements and/or steps in the claims.
Many alterations and modifications may be made by those having ordinary skill in the art without departing from the spirit and scope of the invention. Accordingly, it must be understood that the illustrated embodiments have been set forth only for the purposes of example, and that they should not be taken as limiting the invention as defined by the following claims. Although the elements of a claim are set forth below in a certain combination, it must be expressly understood that the invention includes other combinations of fewer, more or different ones of the disclosed elements.
The words used in this specification to describe the invention and its various embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification the generic structure, material or acts of which represent individual classes.
Thus, in the present specification, the definitions of words or elements in the following claims are to include not only the combination of elements which are literally set forth. In this sense, therefore, it is conceivable: an equivalent substitution of two or more elements may be made for any one of the elements in the claims below or a substitution of two or more elements in a claim to a single element. Although elements may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements from a claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a subcombination or variation of a subcombination.
Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, as now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Accordingly, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements.
The claims are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted and also what incorporates the essential idea of the invention.
