Abstract
Description
Technical Field
[0001] The invention relates to the field of dental orthodontics, in particular to a micro-vibration and collision-free maxillary sinus lifting tool. Background Art
[0002] Dental implant technology has been widely popularized. Usually, a dental implant with a diameter of 4~5mm and a length of 8mm needs to be implanted in the posterior teeth area. However, since the bone at the bottom of the maxillary sinus of many patients is very thin, it is impossible to implant a dental implant with a length of 8mm. It is necessary to perform a maxillary sinus lift surgery to push the mucosa in the maxillary sinus into the maxillary sinus, and then perform a bone grafting surgery before the 8mm long implant can be placed. Maxillary sinus lift is a commonly used technique in oral implantation. It is divided into the impact method and the flat drill grinding method. Among them, the impact method is the most commonly used. The steps are to grind a hole in the bone at the bottom of the maxillary sinus, and then reserve 1~1.5mm of bone at the bottom of the maxillary sinus, and then use the maxillary sinus lift tool to knock, so that the remaining 1~1.5mm bone produces green bone, which enters the maxillary sinus along with the maxillary sinus mucosa.
[0003] Existing maxillary sinus lifting tools have the following disadvantages: the head section is too long, which presses the corners of the patient's mouth when used; the thread of the stop ring is too long, and the thread pressing the corners of the mouth may cause damage to the corners of the mouth, leading to medical disputes; the long axis of the head cannot be perpendicular to the bone at the bottom of the maxillary sinus, resulting in an inclination angle, resulting in uneven force when tapping, increasing the risk of damage to the mucosal membrane of the maxillary sinus floor; the head scale line is the smallest at 6mm, and it is impossible to perform a short-distance maxillary sinus floor lifting display; when the front stop ring and the rear stop ring are used in combination, the exposed length of the head can be adjusted between 6 and 12mm, and it is impossible to adjust it shorter; the depth of the head concave is 1mm, which is too shallow and not easy to cause greenstick fractures; a set of tools usually consists of 5 tools, with head diameters ranging from 2.5mm, 3mm, 3.5mm, 4mm, and 4.5mm, of which those with diameters of 2mm and 4.5mm are rarely used and are redundant. Summary of the invention
[0004] The purpose of the present invention is to improve the surgical tools used in the maxillary sinus lifting impact method, improve the practicality and applicability of the tools, increase the accuracy of the doctor's surgical operation and the patient's comfort during the operation, and reduce the risks during the operation.
[0005] Preferably, a micro-vibration and collision-free maxillary sinus lifting tool consists of a head, a front connecting rod, a middle part, a rear connecting rod, and a tail, which are connected at 10 to 60 degrees each. The front connecting rod, the middle part, and the rear connecting rod form a central recess. The front connecting rod and the rear connecting rod consist of two parts, the front part and the rear part, and the tail and the head are on the same long axis.
[0006] Furthermore, the purpose of this adjustment is to avoid pressure on the corners of the mouth and improve the patient experience. The head and tail are on the same long axis, which can ensure that the force can be transmitted vertically when using the impact method, reduce the lateral tilt of the tool, and reduce the risk of damage to the maxillary sinus floor lining due to uneven force.
[0007] Preferably, a plane formed by the head and the front portion of the front connecting rod and a plane formed by the rear portion and the middle portion of the front connecting rod form an inner angle of 30 to 70 degrees.
[0008] Preferably, a micro-vibration and collision-free maxillary sinus lifting tool has a head scale line of 2 mm for the first scale line, followed by a scale line every 2 mm until the 12 mm scale line.
[0009] Furthermore, the current micro-vibration and collision-free maxillary sinus lifting tool has a shorter thread length than previous tools. This adjustment avoids friction damage caused by compression of the patient's mouth corners.
[0010] Preferably, a micro-vibration and collision-free maxillary sinus lifting tool, whose head stop ring is composed of a front stop ring and a rear stop ring, the stop ring is fixed to the head by threads, the front stop ring is divided into a long front stop ring and a short front stop ring, after the long front stop ring is fixed, it can be interlocked with the rear stop ring at the 2mm scale line on the head, the front stop ring is 7~12mm long, and the rear stop ring is 2~3mm.
[0011] Furthermore, current tools are not compatible with a head exposed length of 3 to 14 mm when using a stop ring. The 3 mm length is for short-distance height lifting positioning, and the 14 mm length is for long-height internal lifting positioning. By replacing the long and short front stop rings and interlocking them with the rear stop ring, 3 to 14 mm internal lifting positioning can be achieved.
[0012] Preferably, a micro-vibration and collision-free maxillary sinus lifting tool has a head diameter of three types: 3mm, 3.5mm, and 4mm, a total head length of 19-25mm, and a middle section length of 20-30mm.
[0013] Furthermore, during the operation, the middle part can be rotated to the inside of the dental arch line, so that the middle section will not collide with the patient's buccal mucosa, the front part will not collide with the mandibular teeth, and will not block the doctor's line of sight. During the flap surgery, large diameters of 4.5mm and above are not used. Patients undergoing internal lifting usually have poor bone density, indicating that bone compression is required. Small diameters of 2.5mm are also not used as they can easily puncture the mucosa of the maxillary sinus floor.
[0014] Preferably, a micro-vibration and collision-free maxillary sinus lifting tool has a concave inner wall of the head that is a vertical side wall with a depth of 1 to 2.5 mm, a triangular protrusion at the bottom of the concave that is about 0.5 to 1 mm high, and a sharp edge on the outer wall of the head.
[0015] Furthermore, the increased depth of the concave portion of the head makes it easier to produce green stick bone at the bottom of the maxillary sinus, thereby increasing patient sensitivity. The triangular protrusion is to prevent bone blocks from being embedded in the concave portion and unable to dislocate. The outer side wall of the head is an outer beveled edge, and the edge is to facilitate bone cutting.
[0016] According to the present invention, a micro-vibration and collision-free maxillary sinus lifting tool is improved by combining the defects of previous maxillary sinus lifting tools, thereby improving the practicality and applicability of the tool, increasing the accuracy of the doctor's surgical operation and the patient's comfort during the operation, and reducing the risks during the operation.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.
[0027] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0028] See also Figure 1 and Figure 2 A micro-vibration and collision-free maxillary sinus lifting tool, the structure of which includes: a head 10, a front connecting rod 20, a middle part 30, a rear connecting rod 40, and a tail 50, which are connected at 40 to 60 degrees. The front connecting rod, the middle part, and the rear part form a middle notch 60. The front connecting rod is composed of a front connecting rod front part 21 and a front connecting rod rear part 22. The rear connecting rod is composed of a rear connecting rod front part 41 and a rear connecting rod rear part 42. The tail and the head are on the same long axis 70.
[0029] For example, a micro-vibration and collision-free maxillary sinus lifting tool is designed to avoid pressure on the corners of the mouth and improve the patient experience. Its head and tail are adjusted on the same long axis to ensure that the force can be transmitted vertically when the impact method is used, reducing the lateral tilt of the tool and reducing the risk of damage to the maxillary sinus floor membrane due to uneven force.
[0030] Exemplarily, a plane formed by the head and the front portion of the front connecting rod forms an inner angle of 30 to 70 degrees with a plane formed by the rear portion and the middle portion of the front connecting rod.
[0031] See also Figure 3 , a micro-vibration and collision-free maxillary sinus lifting tool, the first scale line 11 on the head is 2mm, and there is a scale line every 2mm behind it until the 12mm scale line. Compared with previous tools, the current micro-vibration and collision-free maxillary sinus lifting tool has a reduced thread length. This adjustment avoids compressing the corners of the patient's mouth and causing friction damage.
[0032] See also Figure 3 A micro-vibration and collision-free maxillary sinus lifting tool, the head stop ring of which is composed of a front stop ring 13 and a rear stop ring 14, the stop ring is fixed to the head by a thread, the front stop ring is divided into a long front stop ring 131 and a short front stop ring 132, the long front stop ring can be interlocked with the rear stop ring at the 2mm scale line on the head after being fixed, the front stop ring is 7~12mm long, and the rear stop ring is 2~
[0033] 3mm.
[0034] For example, when using the stop ring, the current tool cannot be compatible with the head exposed length of 3~14mm. The 3mm length is for short-distance height lifting positioning, and the 14mm length is for long-height internal lifting positioning. By replacing the long and short front stop rings and interlocking with the rear stop ring, the 3~14mm internal lifting positioning can be achieved.
[0035] For example, a micro-vibration and collision-free maxillary sinus lifting tool has a head diameter of 3 mm, 3.5 mm, and 4 mm, a total head length of 19 to 25 mm, and a middle section length of 20 to 30 mm.
[0036] For example, the middle part can be rotated to the inside of the dental arch line during the operation, so that the middle part will not hit the patient's buccal mucosa, the front part will not hit the mandibular teeth, and will not block the doctor's line of sight during the flap surgery. Large diameters of 4.5mm or more are not used. Patients who undergo internal lifting usually have poor bone density, indicating that bone compression is required. Small diameters of 2.5mm are also not used because they are easy to puncture the mucosa of the maxillary sinus floor.
[0037] See also Figure 4 , a micro-vibration and collision-free maxillary sinus lifting tool, with a deeper concave head, is more likely to produce green stick bone at the bottom of the maxillary sinus, improving patient sensitivity. When the sinus bottom is 5mm high, the pilot drill 80 is 2.5mm deep, the arrow is 3mm deep, and the bone surface 81 that the lifting tool head contacts is 2.5mm. At present, it is difficult to produce green stick bone when the concave depth of the head is 1mm. It is easier to achieve after the concave head is deepened to 2mm, reducing vibration and improving customer experience.
[0038] See also Figure 5 The inner notch of the head of the maxillary sinus lifting tool is opposite to the midpoint A of the edentulous area of the dental arch line, the axis 3 where the front connecting rod is located is perpendicular to the tangent 4 where the midpoint of the edentulous area on the dental arch line is located to form a coordinate axis, the axis where the front and rear of the front connecting rod are located forms a bending point B, and the axis where the rear of the front connecting section and the middle part are located forms a bending point C, the front of the front connecting rod is on the outer buccal side of the dental arch line, and the rear of the front connecting rod is to allow it to leak out the mouth angle forward, the middle part of the middle notch is parallel to the axis where the head is located, avoiding the mandible, the front and rear of the rear connecting rod are symmetrical with the front and rear of the front connecting rod, and the tail and the head are on the same long axis to ensure uniform force during impact. If the edentulous area is at the other end of another dental arch line, just flip the direction of the maxillary sinus lifting tool.
[0039] See also Figure 6 and Figure 7 A micro-vibration and collision-free maxillary sinus lifting tool, wherein the inner wall 151 of the inner concave 15 of the head is a vertical side wall with a depth of 1-2.5 mm. The bottom of the inner concave has a triangular protrusion 153 with a height of about 0.5-1 mm. The outer wall 152 of the head is a sharp edge of a blade. The triangular protrusion is to prevent bone blocks from being embedded in the inner concave and unable to dislocate. The outer wall of the head is an outer bevel edge, and the edge is to facilitate bone cutting.
[0040] In summary, the present invention provides a micro-vibration and collision-free maxillary sinus lifting tool, which is an improvement and upgrade based on the existing maxillary sinus lifting tools on the market. The improved design parts include: the stop ring thread on the head segment, the head and tail positions, the head scale lines, the combined use of the front stop ring and the rear stop ring, and the inner concave depth of the head. These improved parts improve the practicability and applicability of the tool, increase the accuracy of the doctor's surgical operation and the patient's comfort during the operation, and reduce the risks during the operation.
[0041] In addition, it should be understood that although the present specification is described in terms of implementation modes, not every implementation mode contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment are also appropriately combined to form other implementation modes that are understood by those skilled in the art.
