Problems solved by technology

For patients with complete edentulousness, the surgical guide plate based on bone support technology covers the entire maxilla or mandible, and the coverage area is large, so it is difficult to completely fit the guide plate on the surface of the tooth bone, resulting in errors
The guide plate based on soft tissue support is easy to cause the displacement of the surgical guide plate due to the sliding properties of soft tissue, resulting in inaccurate surgical results
In addition, the current surgical guide plate covers the entire dental bone or gum, and the surgical guide hole is completely embedded in the surgical guide plate and completely sealed with the part covering the dental bone or gum. This design blocks the doctor’s surgical sight, making it impossible for the doctor to Observe the condition of the implanted implants at any time, and often find the problem after removing the surgical guide plate, and make adjustments again, wasting the time of the operation

Embodiment 1

[0010] Embodiment 1: as figure 1 As shown, a surgical guide has a support foot 1, fixing holes 10, 11, 12 and guide holes 2, 3, 4, 5, the support foot 1 is in the shape of a saddle, and the head and tail of the saddle shape are bent in the same direction. There are guide holes 2, 3, 4, 5 and fixing holes 10, 11, 12, guide holes 2, 3, 4, 5 have closed through holes 6, 7, 8, 9, and the diameter of the through holes is between 3mm and 6mm Between, the wall thickness of the guide hole is between 1mm and 5mm. The length of the guide hole is at least 5 mm, and a gap of at least 5 mm is maintained between the lower end of the guide hole and the surface of the dental bone. The fixing holes 10, 11, 12 are in the shape of a hollow column, and the supporting foot 1 is integrated with the guide holes 2, 3, 4, 5 and the fixing holes 10, 11, 12. shape on the outside of the mouth.

[0011] The fixing hole is connected with the guide hole and the supporting foot, and is used for fixing the...

Embodiment 2

[0014] Embodiment 2: as figure 2 As shown, a surgical guide plate, the guide holes 2, 3, 4, 5 are in the shape of a platform, and the outer side of the platform shape is fixedly connected with the inner surface of the fixing holes 10, 11, 12 as a whole.

[0015] figure 2 There is a gap in the surgical guide plate, and the gap is located between the fixing holes 10, 11 and between the fixing holes 12, 11, so that the surgical guide plate can be installed on the support surface of the dental bone 13, and the fixing screw is implanted from the fixing hole. The surgical guide is fixed to the bone. Other structures are the same as in Embodiment 1.

Embodiment 3

[0016] Embodiment 3: as image 3 Shown, a kind of surgical guide plate, guide plate is separated saddle shape support foot 14,15,16, and guide hole 2,3,4,5 and fixing hole 10,11,12 are integrated structure. On the outer surface of the oral cavity, the saddle-shaped supporting foot 14 is connected with a fixing hole 11 , and the inner surface of the fixing hole 11 is fixedly connected to the middle of the guide holes 3 and 4 . The saddle-shaped supporting foot 16 is connected with a fixing hole 10 , and the inner surface of the fixing hole 10 is fixedly connected to the middle part of the guide holes 2 and 3 . The saddle-shaped support foot 15 is connected with a fixing hole 12, and the inner surface of the fixing hole 12 is fixedly connected to the middle part of the guide holes 4,5. The supporting feet 14, 15, 16 of the operation guide plate have the bending in the same direction from the beginning to the end. Other structures are the same as in Embodiment 1.

Abstract

The invention provides a surgical guide plate. The guide plate is characterized by comprising support pins, a fixed hole and a guide hole, wherein the support pins are of saddle shapes, and the head and the tail of the saddle shapes are bent in the same direction; the support pins are connected to the fixed hole, the inside surface of the fixed hole is connected to the platform-shaped guide hole;a closed through hole is formed in the guide hole; a gap of at least 5mm is reserved between the lower end of the guide hole and the surface of dentale; the fixed hole is of a hollow upright post shape; and the support pins, the fixed hole and the guide hole are formed into a whole structure. The surgical guide plate has the beneficial effects that: the surgical guide plate of an oral implant canbe fixed on the dentale by three support pins, so that the wound area of a patient is reduced, and the guide plate is light and easy to operate; the through hole in the guide hole ensures that: the implant is implanted into the dentale (implant position and angle) of the patient according to the predetermined design scheme on a computer, and the gap between the lower end of the guide hole and thedentale surface is convenient for a doctor to observe the implanting condition of the implant at any time in an operation process.

Description

technical field [0001] The invention relates to a surgical guide plate applied to oral implants, which is suitable for patients with complete jaw edentulous, and belongs to the field of oral surgical instruments. Background technique [0002] In the existing surgical techniques, oral implant surgical guides are divided into three categories, one is based on hard tissue (maxilla or mandible) support, the second is based on soft tissue (gingiva) support, and the third is based on Based on tooth surface support. The first two oral guides are suitable for patients with edentulous patients. A third type of surgical guide is available for partially edentulous patients. There are guide holes on the surgical guide plate. During the operation, the guide plate is first fixed on the surface of soft tissue, bone tissue or teeth. The implant is then inserted into the patient's body along the guide hole. The guide holes on the guide plate are simulated on the computer based on 3D CT d...
