Description

Technical Field

[0001] The utility model relates to the technical field of oral laser surgery, in particular to a laser surgery guide device for oral surgery. Background Art

[0002] Water lasers are an emerging technology in dentistry. Their kinetic energy differs from that of conventional dental drills in that they produce no vibration or heat when applied to hard tissue, minimizing pain and oversensitivity in the patient's nerves. Because the 2780nm laser energy directly impacts soft tissue and has appropriate water absorption, it achieves excellent cutting and hemostasis, without the formation of scabs on the wound surface. Apical surgery can save a significant number of teeth that remain refractory to conventional apical periodontitis or have post-and-core restorations that are difficult to retreat with. However, when multiple teeth require apical surgery, particularly in the aesthetically pleasing anterior area, postoperative gingival scarring or poor gingival margin and papilla morphology, often due to factors such as incision design and large flap size, can compromise the aesthetic appearance of the anterior soft tissue. Furthermore, it can be difficult to accurately determine the appropriate root resection and bone removal areas for each tooth, increasing the risk of surgical trauma to hard tissue. Therefore, surgical guides are often necessary to assist with the procedure.

[0003] The current apical surgery guide, such as the guide mentioned in the announcement number CN112914757B entitled "A apical surgery guide and its manufacturing method", includes a tooth support part, a root cutting guide part and an incision guide part. The tooth support part, the root cutting guide part and the incision guide part are detachably connected, and the tooth support part is respectively connected to the root cutting guide part and the incision guide part through a connecting part.

[0004] Before using the above-mentioned guide plate, it is necessary to simultaneously construct the maxillary and mandibular tooth molds, and then use them with one side of the mold as support after assembly, which makes the material cost high; therefore, we propose an oral laser surgery guide plate device to solve the above problem. Utility Model Content

[0005] The purpose of the present utility model is to provide a laser surgical guide device for oral use, so as to solve the problem in the above-mentioned background technology that the existing guide plate needs to construct the maxillary teeth and mandibular teeth molds at the same time before use, and can only be used with one side mold as support after combination, which makes the material cost high.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a laser surgical guide device for oral use, comprising a braces portion, a root cutting guide portion being provided at the upper end of the outer edge of the braces portion, a plurality of root cutting guide portions being provided, and being integrally formed with the braces portion, a positioning groove being provided inside the root cutting guide portion, and a laser barrier being provided inside the positioning groove.

[0007] Preferably, a gum covering groove is provided inside the brace part, and a tooth mold groove is provided inside the gum covering groove.

[0008] Preferably, the laser blocking member includes a clamping section and a limiting edge, the limiting edge is provided at the edge of the front end of the clamping section, and a root cutting groove is provided inside the clamping section.

[0009] Preferably, the laser blocking member is connected to the positioning groove on the root cutting guide plate portion by a snap-fitting section.

[0010] Preferably, the braces portion and the root cutting guide plate portion are both made of silicone material by 3D printing.

[0011] Preferably, the laser barrier is made of ceramic material by 3D printing.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The present invention adopts the braces to carry the root cutting guide part, and the root cutting guide part can be fixed directly by wearing the braces during use. Since only a single-sided model needs to be made according to the maxillary teeth or mandibular teeth, the installation is efficient and the production cost is reduced. This solves the problem that the existing guide plate needs to construct the maxillary teeth and mandibular teeth molds at the same time before use, and can only be used with one side of the mold as support after the combination, which makes the material cost high.

[0014] 2. By installing a laser barrier on the root cutting guide, a root cutting groove is set inside the laser barrier to determine the resection range, so that clinicians can have a clearer and more accurate visual impression of the scope of the apical lesion, thereby improving surgical efficiency and treatment success rate. The laser barrier is made of ceramic material. When the water laser contacts the laser barrier, the high temperature and high pressure resistance of the ceramic material can block the water laser, thereby obtaining a smoother and flatter resection edge.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 The utility model provides an embodiment: a laser surgical guide device for oral use, comprising a braces portion 1, a root cutting guide portion 4 being provided at the upper end of the outer edge of the braces portion 1, a plurality of root cutting guide portions 4 being provided, and being integrally formed with the braces portion 1, a positioning groove 5 being provided inside the root cutting guide portion 4, and a laser blocking member 6 being provided inside the positioning groove 5.

[0022] See also Figure 1 The interior of the braces part 1 is provided with a gum covering groove 2, and the interior of the gum covering groove 2 is provided with a tooth model groove 3. The device adopts a braces structure. It only needs to build a corresponding maxillary or mandibular braces model according to the intraoral 3D optical scanning, and build a root cutting guide plate part 4 model according to the tooth position of the braces model. The guide plate can be fixed in the way of wearing braces, which is efficient and reduces the production cost.

[0023] See also Figure 4 The laser barrier 6 includes a clamping section 601 and a limiting edge 602. The limiting edge 602 is set at the edge of the front end of the clamping section 601. A root cutting groove 603 is set inside the clamping section 601. The root cutting groove 603 in the laser barrier 6 can determine the resection range, so that the clinician can have a clearer and more accurate intuitive impression of the range of the apical lesion, thereby improving the surgical efficiency and treatment success rate.

[0024] See also Figure 1 and Figure 4 The laser barrier 6 is connected to the positioning groove 5 on the root cutting guide plate 4 through the clamping section 601. The laser barrier 6 is made of ceramic material through 3D printing. When the water laser contacts the laser barrier 6, the high temperature and high pressure resistance of the ceramic material can block the water laser, thereby obtaining a smoother and flatter cutting edge.

[0025] Furthermore, the braces portion 1 and the root cutting guide portion 4 are both made of silicone material through 3D printing. The silicone material has a certain elasticity. When it is mounted on the maxillary teeth or mandibular teeth, it can achieve a good fixing effect by relying on the elasticity without the need for additional support.

[0026] Working principle: Before use, the patient's maxillary or mandibular teeth are scanned by a commonly used intraoral 3D optical scanner, and the corresponding maxillary or mandibular braces model is constructed according to the scanning results. The root cutting guide part 4 model is constructed according to the dentition position of the braces model, and a positioning groove 5 is reserved in the root cutting guide part 4. A laser barrier 6 model is constructed according to the positioning groove 5. Then, the braces guide and laser barrier 6 are made by the commonly used 3D printing method, and the laser barrier 6 is installed in the positioning groove 5 of the root cutting guide part 4. The device can be installed, and the root cutting can be completed directly by wearing the braces when in use. The root guide portion 4 is fixed, because only a unilateral model needs to be made according to the maxillary teeth or mandibular teeth, the installation is efficient and the production cost is reduced. A laser barrier 6 is installed on the root cutting guide portion 4, and a root cutting incision groove 603 is provided in the laser barrier 6 to determine the resection range, so that the clinician can have a clearer and more accurate intuitive impression of the range of the apical lesion, thereby improving the surgical efficiency and the success rate of the treatment. The laser barrier 6 is made of ceramic material. When the water laser contacts the laser barrier 6, the high temperature and high pressure resistance of the ceramic material can block the water laser, thereby obtaining a smoother and flatter resection edge.
