Description

Technical Field

[0001] This utility model relates to the field of periodontal surgery technology, and in particular to a periodontal surgery granulation tissue removal instrument kit. Background Technology

[0002] As a routine procedure performed by periodontists, debridement of the infraosseous pocket, below the root bifurcation, and in the alveolar socket is unavoidable. Thorough removal of granulation tissue in these areas is time-consuming and laborious, especially the infraosseous pocket distal to the second molar and the root of the infraosseous pocket / alveolar socket. Currently, there are no related periodontal granulation tissue removal kits on the market. The periodontal surgical granulation tissue removal kit contains 6 instruments. The specific tip design and neck angle can help periodontists thoroughly remove the clinically troublesome granulation tissue, complete the debridement more quickly, and reduce hand fatigue.

[0003] In clinical dentistry, flap surgery, regenerative surgery, and site preservation are among the most common types of periodontal surgery. Their common goal is to thoroughly remove granulation tissue from infraosseous pockets or alveolar sockets, providing sufficient conditions for alveolar bone reshaping or bone implantation. During clinical flap debridement, traditional scaling instruments are often insufficient for efficiently and thoroughly removing granulation tissue from narrow infraosseous pockets, or in posterior teeth, especially distal to the second molar, and below the root bifurcation.

[0004] Currently, the granulation instruments used for periodontal flap surgery, regenerative surgery, and site preservation surgery are either general-purpose curettes or tooth-position-specific Gracey curettes.

[0005] It has three major drawbacks:

[0006] 1. General-purpose curettes used for scaling and root surface smoothing, or tooth-specific Gracey curettes, have a working blade width of 0.9 mm. For narrow subosseous pockets or root bifurcations with a width of <0.9 mm, it is difficult to access them effectively to remove granulation tissue. Inexperienced operators may even get the working end of the instrument stuck in the root bifurcation or subosseous pocket, leading to instrument breakage.

[0007] 2. In periodontal surgery, the periodontal probe is an essential tool. We need it to measure the extent of bone defects (defect width, defect depth, distance from the bottom of the bone defect to the CEJ and alveolar crest) and the safe depth of granulation tissue removal in the alveolar socket (alveolar socket depth, width, thickness of soft tissue on the crest, and height of the indentation septum). Therefore, it is necessary to switch between the periodontal probe and the granulation instrument, which affects the efficiency of the operation.

[0008] 3. Currently, there is no dedicated granulation tissue removal kit. Different doctors have different preferences for the types of instruments they use when removing granulation tissue, and the requirements for instruments vary depending on the location. Frequent changes and unpacking lead to lower efficiency. Utility Model Content

[0018] Furthermore, the working blade tip width of the first alveolar fossa granulation removal instrument is 1.3 mm, and the working blade tip width of the second alveolar fossa granulation removal instrument is 2.5 mm.

[0019] Furthermore, the tip of the working blade of the first alveolar fossa granulation removal instrument is a wide, flat hoe shape with a length of 5-7 mm; the tip of the working blade of the second alveolar fossa granulation removal instrument is an elliptical spoon shape with a length of 5-6 mm.

[0020] Furthermore, the square open-bottom portion includes a frame and bottom openings located at both ends of the appliance, and the rotating handle is rotatably disposed in the front and rear inner cavities of the frame.

[0021] The technical effects and advantages of this utility model are as follows:

[0022] 1. The proposed solution can effectively help doctors remove granulation tissue during clinical practice, reduce the impact of residual granulation tissue on periodontal tissue and bone regeneration, reduce muscle fatigue of doctors, and improve debridement efficiency and the success rate of regeneration.

[0038] The working end of the first bone defect granulation removal instrument 7 is bent 150° in a vertical position, and then bent 113° in the opposite direction at an appropriate length. This allows it to better fit the environment during use and expose a better field of view.

[0039] The working blade tip of the instrument 9 for removing granulation tissue from second bone defects is a round triangle 91 with a length of 2-3 mm. The lengths of the upper, middle and lower ends of the neck of the instrument 9 for removing granulation tissue from second bone defects are 10-11 mm, 8-11 mm and 8-10 mm, respectively.

[0040] The working end of the second bone defect granulation removal instrument 9 is bent 160° in a vertical position and then bent 119° in the opposite direction. This allows it to better fit the environment during use and expose a better field of view.

[0041] The working blade tip of the instrument 10 for removing granulation tissue from third bone defects is short spoon-shaped 101 with a length of 3-4 mm. The lengths of the upper neck, middle neck, and lower neck of the instrument 10 for removing granulation tissue from third bone defects are 11-13 mm, 9-10 mm, and 8-11 mm, respectively.

[0042] The working end of the third bone defect granulation removal instrument 10 is bent at 150° and then bent in the opposite direction at 113°. This allows it to better fit the environment during use and expose a better field of view.

[0043] The working blade tip of the fourth bone defect removal instrument 6 is short hoe-shaped 61 with a length of 2-3mm. The lengths of the upper, middle and lower ends of the neck of the fourth bone defect removal instrument 6 are 13-15mm, 6-8mm and 8-11mm, respectively.

[0044] After bending the working end of the fourth bone defect granulation removal instrument 6 by 140°, it is then bent in the opposite direction by 115°. This allows it to better fit the environment during use and expose a better field of vision.

[0045] The first bone defect granulation removal instrument 7 has no fixed depth line; the second bone defect granulation removal instrument 9 includes fixed depth lines of 3mm, 5mm, 7mm, 8mm, 9mm and 10mm; the third bone defect granulation removal instrument 10 includes fixed depth lines of 3, 6 and 9mm; and the fourth bone defect granulation removal instrument 6 has no fixed depth line.

[0046] In addition, the alveolar socket granulation removal instruments include a first alveolar socket granulation removal instrument 5 and a second alveolar socket granulation removal instrument 8.

Several depth lines are set on the lower end of the neck of the instrument to allow real-time observation of the depth of the bone defect and alveolar socket, as well as the approximate position of the instrument tip, during surgery. This eliminates the need for periodontal probes and improves efficiency.

[0050] After bending the working end of the second alveolar socket granulation removal instrument 8 by 150°, it is then bent in the opposite direction by 103°.

[0051] The aforementioned instrument set, specifically designed for removing granulation tissue in periodontal surgery, features two key components. First, it includes specially designed granulation burs for bone defects and alveolar sockets with varying neck curvatures and blade shapes. These work synergistically to improve the efficiency of granulation tissue removal, reduce the need for experienced surgeons, and minimize hand fatigue and operation time. Second, several depth lines are incorporated into the lower end of the neck of specific instruments, allowing for real-time monitoring of the depth of bone defects and alveolar sockets, as well as the approximate position of the instrument tip, eliminating the need for periodontal probes and further enhancing efficiency. This instrument set is suitable for various periodontal flap surgeries and bone grafting procedures requiring granulation tissue removal.
