Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to a palatal mucosa spreading guide plate used for extracting impacted supernumerary teeth in the maxillary bone. Background Art

[0002] Supernumerary teeth are a common developmental dental anomaly. Imbedded in the bone, these teeth present challenges such as difficulty locating them, lengthy procedures, potential damage to surrounding tissues, and severe postoperative complications. Ninety percent of maxillary anterior bony supernumerary teeth require palatal mucosal fenestration. The surgical procedure involves local anesthesia, creation of an incision within the maxillary gingival sulcus, elevation of the palatal mucosal flap, freeing the nasopalatine nerve, removal of the overlying bone plate using a turbine, extraction of the supernumerary tooth, and hemostasis and closure of the wound. During the procedure, the palatal mucosal flap requires retraction. Conventional methods involve the use of retractors or other instruments to hold the retracted palatal mucosa in place, facilitating surgical manipulation. However, this method requires the assistant to maintain constant support, which is labor-intensive and difficult to control, potentially damaging the palatal mucosa, the nasopalatine nerve, and other tissues. Furthermore, the instruments used to re-open the mucosa obstruct the attending physician's field of view, compromising both the surgical field of view and the accuracy of the procedure. Utility Model Content

[0007] The guide plate is fixed to the inner side of the abutment retainer, and is used for stretching the palatal mucosa.

[0008] Furthermore, a teardrop-shaped notch is provided at the bottom of the guide plate to avoid the palatal mucosa and the nasopalatine nerve.

[0009] Furthermore, the guide plate is an arched structure.

[0010] Furthermore, the abutment retainer is of hollow design.

[0011] Furthermore, the abutment retainer and the guide plate are made of silicone.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Therefore, the detailed description of the embodiments of the present application provided below in conjunction with the accompanying drawings is intended to represent only selected embodiments of the present application and is not intended to limit the scope of protection claimed in the present application. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present application without making any creative efforts shall fall within the scope of protection claimed in the present application.

[0023] See Figure 1 The utility model provides a palatal mucosa spreading guide plate for extracting impacted supernumerary teeth in the maxilla, comprising an abutment retainer 1 and a guide plate 2.

[0024] The abutment retainer 1 provides a fixed position for the guide plate 2 , and the contour of the abutment retainer 1 is consistent with the contours of a plurality of abutment teeth located in the maxillary bone.

[0025] The guide plate 2 is fixed to the inner side of the abutment retainer 1 , and the guide plate 2 is used to open the palatal mucosa.

[0026] In the present application, the overall contour of the abutment retainer 1 is consistent with the contour of the corresponding abutment tooth. During use, it is placed on the corresponding abutment tooth, and the guide plate 2 is fixed to the inner side of the abutment retainer 1. The provision of the guide plate 2 ensures the stability of the palatal mucosal expansion effect, avoiding the traditional technique of using retractors or other instruments to block the palatal mucosa during expansion, which is laborious, obstructs vision, and may damage the mucosa due to improper force control. The use of this palatal mucosal expansion guide not only saves effort and is convenient to operate, but also does not damage the mucosa, nor does it obstruct vision and affect surgical operations.

[0027] Optionally, a teardrop-shaped notch 3 is provided at the bottom of the guide plate 2 to avoid the palatal mucosa and the nasopalatine nerve.

[0028] like Figure 2 As shown, in order to avoid damage to tissues such as the palatal mucosa and the nasopalatine nerve, a teardrop-shaped notch 3 is provided at the center of the bottom of the guide plate 2 to avoid tissues such as the palatal mucosa and the nasopalatine nerve.

[0029] Optionally, the guide plate 2 is a bow-shaped structure.

[0030] like Figure 1 As shown, the guide plate 2 is an overall arched structure, and the arched surface is curved outward. The arched structure design can better support the incised palatal mucosa.

[0031] Optionally, the abutment retainer 1 is of hollow design.

[0032] like Figure 1 As shown, a plurality of hollows 4 are provided on the abutment retainer 1. The hollows 4 generally correspond to the positions where adjacent abutments intersect, or are located at the positions where the crowns protrude. The hollow design makes the abutment retainer 1 more comfortable to use and easier to wear.

[0033] Optionally, the abutment retainer 1 and the guide plate 2 are both made of food-grade silicone and are integrally formed.

[0034] Optionally, the abutment retainer 1 and the guide plate 2 are prefabricated by digital or traditional impression technology.

[0035] In summary, the utility model provides a palatal mucosa expansion guide for the extraction of impacted supernumerary teeth in the maxilla. Through the design of the abutment retainer and the guide, the surgical operation space is clearly guaranteed, thereby improving the accuracy and safety of the operation. The doctor does not need to manually expand the mucosa or rely on assistants, which reduces the manpower requirements and fatigue during the operation. The design of the notch on the guide avoids important structures such as the palatine nerve, reducing the risks during the operation. The use of the palatal mucosa expansion guide makes the operation simpler and faster, reduces the operation time, and improves the success rate of the treatment. At the same time, the accuracy of the operation greatly reduces the possibility of postoperative pain and bleeding, thereby reducing the risk of postoperative complications.

[0036] The above is merely the preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application shall be included in the scope of protection of this application. Therefore, the scope of protection of this application shall be based on the scope of protection of the claims.
