Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, specifically a detachable and precisely positioned maxillary complete denture. Background Technology

[0002] Complete dentures consist of two parts: artificial teeth and denture base. The denture base adheres to the alveolar ridges of the upper and lower jaws by the suction force and atmospheric pressure generated by the close fit between the denture base and the edentulous jaw mucosa, restoring the patient's damaged tissues and facial appearance, and restoring chewing and speech functions. The mucoperiosteum and bone tissue covered by the denture base bear the occlusal pressure of the denture.

[0003] For example, Chinese Patent CN222217987U, published on December 24, 2024, discloses a quick-positioning maxillary complete denture, including a maxillary jaw body and several detachable denture bodies disposed at the bottom of the maxillary jaw body. The top of the maxillary jaw body has a positioning groove, and two suction elements are installed at the bottom of the inner wall of the positioning groove. It also includes a connecting block, which is installed on the top of the denture body. A slot is provided at the bottom of the maxillary jaw body corresponding to the position of the connecting block. This invention, through the cooperation of connecting blocks, slots, fixing blocks, annular blocks, stop blocks, openings, moving blocks, fixing grooves, sliders, moving rods, pull blocks, buffer springs, locking blocks, locking slots, arc-shaped sealing blocks, and fastening bolts, facilitates the removal and replacement of individual denture bodies that need to be replaced, avoiding the need to replace the entire jawbone during replacement and reducing resource waste during replacement.

[0004] As can be seen from the above patents, although the maxillary complete denture is convenient for replacing individual dentures, in actual use, because each denture needs to be positioned, gaps can easily form between individual dentures, thus affecting the overall positioning accuracy and stability of the complete denture. Therefore, this utility model provides a detachable, precisely positioned maxillary complete denture to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a detachable, precisely positioned maxillary complete denture.

[0008] A plurality of anchors are provided for precise positioning of the denture base, and the anchors are implanted under the corresponding alveolar bone mucosa of the maxillary alveolar bone.

[0009] A plurality of fixing holes are provided on the surface of the denture base for matching and fixing the plurality of anchors.

[0010] A plurality of miniature neodymium iron boron permanent magnets are used to fix the denture base, and the miniature neodymium iron boron permanent magnets are embedded and installed in the fixing holes;

[0011] A plurality of denture bodies, the denture bodies being used to form a complete denture, the denture bodies being arranged sequentially on the denture base.

[0012] Preferably, the anchor is made of titanium alloy, the surface of the anchor has a porous structure, and the end face of the anchor near the denture base is a magnetic adsorption surface.

[0015] Preferably, the micro NdFeB permanent magnet extends 3-5 mm through the denture base into the denture body.

[0031] Reference Figure 1-2 This utility model discloses a detachable, precisely positioned maxillary complete denture, comprising a denture base 1, a maxillary alveolar bone 2, anchors 3, fixation holes 4, miniature neodymium iron boron permanent magnets 5, and a denture body 6. Several titanium alloy anchors 3, used for precisely positioning the denture base 1, are implanted submucosally into the corresponding alveolar bone of the maxillary alveolar bone 2 via minimally invasive surgery. The surface of the anchors 3 has a porous structure to promote osseointegration between the anchors 3 and the maxillary alveolar bone 2. Several fixation holes 4, used for matching and fixing the anchors 3, are provided on the surface of the denture base 1; several miniature neodymium iron boron permanent magnets 5, used for fixing the denture base 1, are embedded and installed in the fixation holes 4; the denture body 6 is arranged sequentially on the denture base 1.

[0032] In an optional embodiment, the number of anchors 3, fixing holes 4, and micro neodymium iron boron permanent magnets 5 are equal and their positions and specifications are matched to accurately position and fix the denture base 1 and the denture body 6.

[0033] In an optional embodiment, the end face of the anchor 3 near the denture base 1 is a magnetic adsorption surface; it can be used with the micro neodymium iron boron permanent magnet 5 to fix and reinforce the denture base 1 and the maxillary jaw 2 by magnetic attraction, while accurately positioning the denture body 6.

[0034] In an optional embodiment, the anchor 3 protrudes from the maxillary alveolar 2 by a length equal to the depth of the fixing hole 4 after the placement of the micro NdFeB permanent magnet 5, in order to achieve a proper fit between the maxillary alveolar 2 and the denture base 1. The micro NdFeB permanent magnet 5 extends 3-5 mm through the denture base 1 into the denture body 6, so that the denture body 6 can be precisely positioned onto the denture base 1 by the micro NdFeB permanent magnet 5. The edges of the denture base 1 are made of flexible silicone material to reduce pressure.

[0035] The working principle and usage process of this utility model are as follows:

[0036] First, the anchor 3 is implanted under the alveolar bone mucosa corresponding to the pre-planned maxillary alveolar bone 2 through minimally invasive surgery. After 3-6 months of healing, an impression is taken to fabricate the denture base 1 and the complete denture containing several denture bodies 6. The anchor 3 and the fixing hole 4 are used for precise positioning. The magnetic adsorption surface of the anchor 3 and the micro neodymium iron boron permanent magnet 5 attract each other to reinforce the denture base 1 and the maxillary alveolar bone 2. Then, the complete denture containing several denture bodies 6 is precisely positioned and fixed to the denture base 1 by the micro neodymium iron boron permanent magnet 5.

[0037] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
