Description

[0001]Modified Lucas Dental Curette (Charry Dental Curette). DESCRIPTIVE MEMORANDUM TECHNICAL FIELD OF THE INVENTION This utility model focuses on the field of dental devices, specifically a dental curette, and more specifically, a modified Lucas dental curette with added cutting grooves or ridges that debride or remove diseased tissue. Various curette sizes / dimensions are available, allowing for the treatment of both large and small, hard-to-reach lesions while maintaining the instrument's effectiveness. BACKGROUND OF THE INVENTION In the field of dentistry, different instruments are used for cleaning and removing debris from teeth. One such instrument is the dental curette, a handheld instrument used for cleaning and treating the surface of teeth and gums.There are different types of curettes, which generally have some type of hook or spoon at their ends. One of these is the so-called "Lucas curette," a double-ended dental surgical instrument with a spoon-shaped end, used for curettage, cyst removal, and debridement of tooth sockets. They are available in various sizes and formats, both serrated (with teeth) and unserrated. Serrated curettes have small teeth, are not very deep, and have symmetrical and even teeth, both at the tip and along the entire circumference of the spoon (Figure: Modified Lucas dental curette (Charry dental curette)).While these curettes, especially the serrated ones, are designed for this purpose, they remain inefficient for lesion removal. Their small, even, and shallow teeth prevent them from properly cutting, removing, debriding, or detaching the entire lesion from the root (whether a cyst or a granuloma). Many only turn the lesion over but don't remove it completely, requiring extensive scraping of the affected area to remove all the damaged tissue. This necessitates the use of other tools and makes the surgical process longer, more expensive, and more laborious. Dental curettes (serrated and non-serrated) and other similar dental tools are available on the market.

Alveolar curettes are used to remove bone tissue, cystic tissue (especially apical granulomas), or granulation tissue from the uninhabited socket. LUCAS curettes ensure the detachment and enucleation of cystic tissue. They have improved cutting properties thanks to their serrated edges, which act like a saw for cutting and removal. Sharper than standard LUCAS curettes, serrated LUCAS curettes are used for more invasive applications, allowing them to work on tougher tissues and providing better deep curettage of the socket. This curette has teeth all around the tip and is oval-shaped. However, this document does not describe a modified serrated curette, based on the uneven tooth configuration and shape of the curettes of the present invention.

The active part of this instrument is a spoon-shaped tip with sharp edges. However, this document does not describe a modified toothed curette, given the uneven tooth configuration and the shape of the curettes of the present invention. Therefore, there is a need to develop new curettes to improve the effectiveness of cyst removal and debridement of dental sockets, achieving proper and complete removal of damaged tissue. While many serrated Lucas curettes exist, including modified Lucas dental curettes (Charry dental curettes), they all have small, even teeth, poor grip, shallow depth, and are more suited for scraping than removing root tissue.SUMMARY OF THE INVENTION Whereas current serrated curettes are all of the flattened spoon type, and there are no other more elongated or deeper concave configurations to reach small, hard-to-access spaces within teeth, they remain inefficient for the complete removal of damaged tissue. Consequently, the present invention solves this problem by means of a modified dental curette for debriding or removing diseased tissue, comprising cutting grooves or ridges to form larger, deeper, and sharper irregular asymmetric teeth around the entire spoon, which also has a deeper or more pronounced concavity.

OF THE INVENTION For a better understanding of the present invention, the following definitions are necessary, which should only be understood as elements that aid in understanding the particular technical characteristics in this field. As used in the present invention, the term “dental curette” refers to a hand instrument used by dental professionals to perform cleaning and surface treatment procedures on the teeth and gums. As used in the present invention, the term “dental soft tissue” is all the tissue of the body that is not hardened by ossification or calcification processes, such as bones and teeth. Soft tissues connect, surround, or support internal organs and bones, and include muscles, tendons, ligaments, fat, fibrous tissue, skin, lymphatic and blood vessels, fascia, and synovial membranes.As used in the present invention, the term “dental soft tissue” refers to the tongue, gums, inner lining of the cheeks, and dental pulp. As used in the present invention, the term “dental pulp” is what is commonly called the “nerve” and is located in the center of the tooth. The dental pulp is composed of nerve endings and blood vessels, among other tissues, and its function is to provide sensation and nourishment to the tooth. The tooth is embedded in the bone that houses it by means of the periodontal ligament and protected by the gums and other tissues of the oral cavity. Modified Lucas dental curette (Charry dental curette). As used in the present invention, the term “debride,” or surgical cleaning, refers to the removal of dead, damaged, or infected tissue to improve the health of the remaining tissue.As used in the present invention, the term “Dental Cyst” refers to a type of lesion that forms a rounded cavity within the jawbone. It is relatively common and easy to treat. These lesions are usually benign, not cancerous, but in some cases, they can become malignant. The dental cyst is composed of cells, fluid, and air that divide and grow, destroying the jawbone in which they are located. They can originate from latent infections of decayed teeth, impacted canines that remain embedded in the bone, or embryonic structures that remain within the bone. As used in the present invention, the term “Dental Granuloma” refers to a chronic inflammation affecting the root apex of the tooth, often asymptomatic, a sign of degeneration of the dental pulp.When a dental pulp infection spreads to the periapex, an abscess or acute lesion develops. This periapical lesion can recur, resulting in a periapical granuloma, which is a radicular cyst or scar tissue. A pyogenic granuloma, on the other hand, is a small, non-neoplastic growth or swelling that typically appears around the root apex or the gingiva in the oral cavity. The appearance of an oral pyogenic granuloma can be due to multiple factors, but most often it arises from the presence of an oral disease. In the first aspect of the invention, the design of the curette is presented, which incorporates cutting grooves or ridges that debride or remove the diseased tissue. Various curette sizes are available, allowing for the treatment of larger lesions while maintaining the instrument's effectiveness.This involves a change to the active part and the incorporation of a special cut and design. Modified Lucas dental curette (Charry dental curette). In a second aspect of the invention, the modified Charry curette features deeper, asymmetrical teeth (Figures 2 and 3) around the entire contour of the curette's ends. Three sizes are available: large, medium, and small (the small being elongated or the small being rounded), which vary in width, size, tooth spacing, curette concavity / depth, and curette flatness. Another advantage is that our invention allows for the efficient removal of soft tissue remnants (cysts and granulomas) and necrotic dental tissue present in the oral cavity, which is not possible with the serrated Lucas curettes available on the market.Thus, the technical advantages of the invention are explained through the accompanying description, examples, and figures. For instance, in a non-limiting embodiment, the modified Charry curettes of the present invention can be presented in a toothed spoon format with large, deep, irregular teeth (Figure 2), as well as with uneven, irregular teeth (Figure 3). However, the invention is not limited to the design of the figures. Therefore, the present invention is intended to be protected in the following non-limiting embodiments: 1. A modified dental curette for debriding or removing diseased tissue, comprising cutting grooves or ridges to form larger, deeper, and sharper, irregular, asymmetric teeth around the entire spoon, which also has a deeper or more pronounced concavity. 2.The modified dental curette of point 1, where the spoon can be rounded or elongated. Modified Lucas dental curette (Charry dental curette). 3. The modified dental curette of point 2, where it is designed in large, medium, or small sizes. 4. The modified dental curette of point 3, where the large modified dental curette with irregular asymmetric teeth is rounded in shape. 5. The modified dental curette of point 3, where the medium modified dental curette with irregular asymmetric teeth is rounded in shape. 6. The modified dental curette of point 3, where the small modified dental curette with irregular asymmetric teeth can be rounded or elongated in shape. 7. The modified dental curette of point 6, where the small modified dental curette with irregular asymmetric teeth is rounded in shape. 8.The modified dental curette from point 6, where the modified dental curette with small, irregular, asymmetrical teeth is elongated in shape. 9. The modified dental curette from point 1, where all the irregular teeth are long, large, and deep. 10. The modified dental curette from point 1, where the irregular teeth are of different sizes, lengths, shapes, and depths. EXAMPLES: Modified Lucas dental curette (Charry dental curette). The description of the rigorous tests for the functionality of the utility model, as well as the different configurations and specific uses of the modified curette, are shown in the following application examples. Example 1: Initial prototypes.The initial prototype of the modified Charry curette aimed to lengthen the teeth of traditional serrated Lucas curettes, making them longer, deeper, and larger. The concavity of the curette was also improved to increase its depth. These initial prototypes were produced in large, medium, and small sizes, with the small one designed as an elongated curette to reach the pulp in hard-to-access areas and deeper lesions. The design differences between the modified Charry curettes and commercially available serrated curettes are shown in Figure 2. As can be seen, commercially available serrated curettes have much flatter, smaller, rounded teeth, shallower depth, and a much flatter curette. Example 2: Different asymmetries and sizes for different applications.Following the initial prototype in Example 1, work was done to improve the characteristics of the curettes, designing them in Long, Medium, and Small sizes (Figure 3). Additionally, modifications were made to the symmetry of the grooves to create curettes with irregular, asymmetrical teeth. These teeth provide better tissue grip and sharper edges, enabling them to scrape, cut, and remove the entire cyst, granuloma, or alveolar lesion. As shown in Figure 3, different sizes and shapes of irregular, asymmetrical curettes are available: the large curettes are for removing large lesions, while the small curette is used for scraping fine details. For example, when using the modified Lucas dental curette (Charry dental curette) on incisors (where the alveoli are narrow), the small curettes are indicated. However, for larger lesions, the medium or large curettes are used depending on whether it is a premolar or a molar.Furthermore, the small, elongated curette format (Figure 2, number 4) is useful for hard-to-reach lesions (such as those in the posterior teeth of the oral cavity). Its elongated shape differs completely from current Lucas curettes and was designed this way because current curettes are usually round, spoon-shaped, but in hard-to-reach areas they cannot reach the pulp chamber, which can be achieved with a small, elongated curette. Example 3: Patient Case 1 – Tests on a pulp lesion. A minor clinical surgery was performed on a patient with a lesion (Figure 4), showing a tooth where the pulp became infected because the patient did not receive root canal treatment, resulting in a pulpal lesion (where the root ends, seen as a darker area in the photograph of Figure 4, within the red circle).The most common lesions are cysts and granulomas. However, when this lesion was treated with the commercially available serrated Lucas curette, it only circled the lesion but did not remove it. Therefore, when the curettes of the present invention were used, the damaged tissue was successfully removed because they have asymmetrical teeth or grooves that allow the lesion to be removed from the root. Consequently, no additional tools were needed, and the surgery time was not extended. Example 4: Patient Case 2 - Tests on a lower jaw lesion. in the lower jaw (Figure 5). As shown in the figure, the area of ​​the lesion is circled in red, which is considered a granuloma (because it does not have liquid content within the lesion) and which could not be removed correctly with the serrated Lucas dental curettes available on the market. Modified Lucas dental curette (Charry dental curette). In this case, the curettes used for lesion removal were modified dental curettes, sized according to the size of the lesion. Example 5: Patient Case 3 - Tests on maxillary lesion. In this third case, a patient with a lesion in the maxilla is shown (Figure 6). As the figure shows, the area of ​​the lesion, which encompasses both the liquid inside the lesion) and that could not be removed. Lucas's sawn dental instruments, available on the market. In this case, the For the removal of the lesion, modified “Charry” dental curettes of medium and small size were used, given the size of the lesion, and because in the teeth, the space is narrower.
