[0031] Please refer to the accompanying drawings Figures 1 to 5 The auxiliary jaw resection device provided in one embodiment of the present application comprises a guide plate layer 10 and a soft pad layer 20 connected to the inner side of the guide plate layer 10. The soft pad layer 20 comprises a first section 210, a second section 220 and a third section 230 connected in sequence along the extension direction of the soft pad layer 20. The first section 210 is used for being attached to the inner wall 30 of the alveolus. The second section 220 is used for wrapping the dental crown 50. The third section 230 is used for being attached to the outer wall 40 of the alveolus. Preferably, the first section 210, the second section 220 and the third section 230 are integrally formed.

[0032] The guide plate layer 10 comprises a fourth section 110, a fifth section 120 and a sixth section 130 connected in sequence along the extension direction of the guide plate layer 10. The shape of the fourth section 110 matches the shape of the first section 210. The shape of the first section 210 matches the shape of the fourth section 110 and is bonded to the inner wall of the fourth section 110. The shape of the second section 220 matches the shape of the fifth section 120 and is bonded to the inner wall of the fifth section 120. The shape of the third section 230 matches the shape of the sixth section 130 and is bonded to the inner wall of the sixth section 130. Preferably, the fourth section 110, the fifth section 120 and the sixth section 130 are integrally formed.

[0033] The sixth section 130 is provided with a first positioning hole 133 for the cutting device (not shown in the figure) to penetrate. The third section 230 is provided with a second positioning hole 231 corresponding to the first positioning hole.

[0034] Specifically, the guide plate layer 10 provides main support and positioning functions, and the padding layer 20 is used to contact the alveolar bone and crown 50. The padding layer 20 can reduce patient discomfort. In another embodiment, the padding layer 20 may not be provided. The padding layer 20 has a first segment 210, a second segment 220, and a third segment 230 along its extension direction. The first segment 210 is attached to the inner wall 30 of the alveolar bone, the second segment 220 wraps around the crown 50, and the third segment 230 is attached to the outer wall 40 of the alveolar bone. The padding layer 20 and the guide plate layer 10 can be configured into various similar structural forms according to different age groups or typical oral structures, so that the guide plate layer 10 can match the inner wall 30 and the outer wall 40 of the alveolar bone, forming a clamping-like form in space.

[0035] The padding layer 20 is preferably made of a soft, easily bonded, and easily cut material to reduce patient discomfort. Preferably, the padding layer 20 is made of silicone or polyurethane.

[0036] The first positioning hole 133 on the sixth segment 130 is used to guide the cutting device (such as a bone saw) to make precise cuts. The first positioning hole 133 can be determined in advance according to the alveolar bone defect and the current cutting area. For example, the size of the first positioning hole 133 can be determined according to the defect area, and the position of the first positioning hole 133 on the sixth segment 130 can be determined according to the target cutting area. Positioning marks can be made in advance on the outer wall of the sixth segment 130, and then the first positioning hole 133 and the second positioning hole 231 are cut out. The diameter of the first positioning hole 133 can be appropriately set to be slightly larger than the size of the defect area. It is preferred that the peripheral margin is controlled at 2-3 mm to ensure that a certain margin is left when grinding the cut bone later.

[0037] The second positioning hole 231 on the third segment 230 corresponds to the first positioning hole 133. The soft pad layer 20 and the guide plate layer 10 are bonded together, so attention should be paid to alignment during the bonding process. The second positioning hole 231 can be determined according to the size and position of the first positioning hole 133. With the assistance of the first positioning hole 133 and the second positioning hole 231, the cutting device can be accurately guided to perform jawbone resection.

[0038] Furthermore, since the padding layer 20 and the guide plate layer 10 match the shape of the oral cavity, they are less likely to shift during the removal of the jawbone, thereby improving the removal accuracy. For example, when taking bone from the area directly below the mandible, the structure of this application can be hooked onto the crown 50, and only slight hand assistance is needed during the cutting process.

[0039] In a preferred embodiment, the outer wall of the third segment 230 is provided with a plurality of first scale lines 131 arranged at intervals along its own extension direction, and a plurality of second scale lines 132 arranged at intervals and perpendicularly intersecting the first scale lines 131. The plurality of first scale lines 131 and the plurality of second scale lines 132 intersect to form a plurality of positioning cells 134, which are used to assist in cutting to form the first positioning hole 133.

[0040] Specifically, the setting of the first scale line 131 and the second scale line 132 can provide a positioning basis for the cutting of the first positioning hole 133 and the second positioning hole 231, thereby improving the accuracy of the first positioning hole 133 and the second positioning hole 231, and ultimately improving the accuracy of the jawbone cutting dimensions.

[0041] In a preferred embodiment, the inner wall of the fifth segment 120 is formed with a groove that matches the crown 50. Specifically, the matching design of the groove and the crown 50 ensures the stability of the structure in the oral cavity. When the structure is placed in the oral cavity, the groove can tightly wrap around the crown 50, reducing the risk of displacement or dislodgement of the device during surgery. For example, when the width of the fourth segment 110 is set to 3cm, it covers several teeth laterally. Through the engagement of the groove and the crown 50, the lateral displacement of the structure can be effectively prevented.

[0042] As a preferred example, the width of the fourth segment 110 is set between 2cm and 3cm, and the length of the fourth segment 110 is set between 1cm and 2cm.

[0043] As a preferred example, the width of the sixth segment 130 is set between 2cm and 4cm, and the length of the sixth segment 130 is set between 2.5cm and 4cm.

[0044] As a preferred example, the spacing between two adjacent first scale lines 131 is set between 2mm and 4mm, and the spacing between two adjacent second scale lines 132 is set between 2mm and 4mm.

[0045] Furthermore, both the guide plate layer 10 and the padding layer 20 are transparent. The transparent structure facilitates observation during operation.

[0046] As a preferred example, the thickness of the guide plate layer 10 is set between 2 mm and 4 mm.

[0047] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
