Description

Technical Field

[0001] This utility model relates to the field of dental implant surgery technology, specifically to a positioning auxiliary device for minimally invasive dental implant surgery. Background Technology

[0002] Tooth loss can have a variety of negative impacts, including on oral health, diet, facial appearance, speech, and mental health. After tooth loss, chewing function weakens, potentially causing adjacent teeth to tilt and the dentition to deform, leading to food impaction and cavities. Missing teeth can also affect the health of the temporomandibular joint, causing facial pain and clicking sounds when opening and closing the mouth. Tooth loss can lead to difficulty chewing, affecting the grinding and breakdown of food, thus impacting overall digestion and absorption, potentially causing malnutrition and gastrointestinal problems.

[0003] Teeth are an important part of the face, and their loss can alter facial contours. In particular, missing front teeth can cause embarrassment when smiling or speaking, affecting self-confidence and social skills. Long-term tooth loss can lead to facial muscle relaxation and atrophy of surrounding tissues, making the face appear older. Teeth play a supporting role in pronunciation; their loss can result in unclear pronunciation, affecting speech and communication. Tooth loss can also cause psychological harm such as low self-esteem, anxiety, and depression. Therefore, it is important to restore missing teeth promptly.

[0004] Currently, dental implant surgery includes conventional and minimally invasive procedures. The conventional procedure involves first incising the alveolar ridge mucosa in the edentulous area, raising a flap to expose the alveolar ridge and alveolar process, preparing the cavity, and then implanting the implant before suturing the mucoperiosteal flap. Because the oral cavity is a bacterial environment, postoperative pain, swelling, and other infection symptoms are possible. With the development of digital technology, minimally invasive implant surgery has emerged. The mainstream methods include using digital implant guides or implant navigation positioning. These methods offer accurate implantation point positioning and minimal postoperative reactions, but they have disadvantages such as longer preoperative preparation periods, more auxiliary equipment, higher costs, and more complex procedures. Utility Model Content

[0005] The purpose of this invention is to provide a positioning aid for minimally invasive dental implant surgery to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning auxiliary device for minimally invasive dental implant surgery, comprising: a positioning measuring column, wherein a guide hole is provided inside the positioning measuring column, the guide hole penetrates the entire positioning measuring column, a grip handle is fixedly connected to one side of the positioning measuring column, a buccal-lingual positioning ruler is provided at the top of the positioning measuring column, the buccal-lingual positioning ruler is movably installed between the positioning measuring column, and a limit rod is fixedly connected to the left end of the buccal-lingual positioning ruler.

[0007] Preferably, a marking ring is fixedly connected to the bottom of the positioning measuring column, the marking ring is located directly below the guide hole, and a limit rod fixing screw is fixedly installed on the top of the positioning measuring column by thread.

[0008] Preferably, the top of the positioning measuring column is provided with a threaded hole, which is compatible with the limiting rod fixing screw. The cheek tongue positioning ruler and the positioning measuring column are fixedly installed by the limiting rod fixing screw.

[0009] This invention provides a positioning aid for minimally invasive dental implant surgery. It has the following beneficial effects:

[0010] (1) By setting buccal and lingual positioning rulers and limiting rods, this utility model can quickly perform positioning operations under the combined action of CBCT. Compared with the traditional implantation method of "free hand", the implantation site and direction of the dental implant are more accurate, the operation time is shorter, the postoperative reaction is smaller, the cost of this device is not high, and it will not increase the surgical cost and the burden on the patient too much.

[0011] (2) This utility model allows for convenient operation of the entire auxiliary device by holding the handle and buccal-lingual positioning ruler. Under the action of CBCT, the positioning of the guide hole and the buccal-lingual central area of ​​the alveolar bone in the edentulous area can be achieved by adjusting the position of the buccal-lingual positioning ruler. Compared with digital dental implant guides and dental implant navigation systems, the difference in positioning accuracy is not significant, but there are huge advantages in preoperative preparation time and cost.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] Example 1

[0020] A preferred embodiment of the positioning auxiliary device for minimally invasive dental implant surgery provided by this utility model is, for example... Figure 1-4 As shown: A positioning auxiliary device for minimally invasive dental implant surgery includes: a positioning measuring column 1, a guide hole 11 is provided inside the positioning measuring column 1, the guide hole 11 passes through the entire positioning measuring column 1, a grip handle 2 is fixedly connected to one side of the positioning measuring column 1, a buccal-lingual positioning ruler 3 is provided on the top of the positioning measuring column 1, the buccal-lingual positioning ruler 3 is movably installed between the positioning measuring column 1, and a limit rod 31 is fixedly connected to the left end of the buccal-lingual positioning ruler 3;

[0021] The positioning measuring post 1 has two widths: 5.6mm and 6.5mm. The guide hole 11 has a diameter of 2.2mm. A guide drill can be used to prepare the alveolar bone cavity along the guide hole 11. The handle 2 is connected to the outer wall of the positioning measuring post 1. By adjusting the handle 2, the position of the entire auxiliary device can be adjusted while ensuring the stability of the device. After measuring the buccal and lingual width of the edentulous area by CBCT, the limiting rod fixing screw 5 is loosened, and the position of the limiting rod 31 is adjusted to be equal to the measured width, which facilitates the positioning of the guide hole 11.

[0022] CBCT, or cone-beam computed tomography, is an imaging technique widely used in the fields of oral and maxillofacial region and head and neck. Its working principle is to use a cone-beam X-ray beam to rotate around the object being scanned and acquire projection data from multiple angles. This projection data is processed by computer algorithms to reconstruct a three-dimensional image, which can provide high-resolution tomographic images and clearly show the internal structure of the object.

[0023] Example 2

[0024] Based on Embodiment 1, a preferred embodiment of the positioning aid device for minimally invasive dental implant surgery provided by this utility model is as follows: Figure 1-4As shown: The bottom of the positioning measuring column 1 is fixedly connected to an imprint ring 4, which is located directly below the guide hole 11. The top of the positioning measuring column 1 is fixedly installed with a limit rod fixing screw 5 by a thread. The top of the positioning measuring column 1 is provided with a threaded hole 51, which is compatible with the limit rod fixing screw 5. The cheek tongue positioning ruler 3 is fixedly installed with the positioning measuring column 1 by the limit rod fixing screw 5.

[0025] This auxiliary device is available in two sizes: 3.6mm and 4.5mm. The imprint ring 4 is used to make an imprint on the alveolar ridge mucosa in the edentulous area, which facilitates soft tissue trephine drilling. According to the pre-imprinted imprint, the mucoperiosteum is drilled to expose the alveolar ridge bone tissue.

[0026] This device is compatible with most brands of implant kits, eliminating the need to purchase new implant kits at an additional cost. It can also be used with minimally invasive implant kits that come with this device. This device is available for both left and right sides. One device can be used for a single missing tooth, while multiple devices can be used side by side for multiple missing teeth.

[0027] When using the device, select the appropriate size locator based on the width of the edentulous gap. For example, if the gap width is between 5.6-6.5mm, select a 3.6mm locator. Adjust the value of the limiting rod based on the buccal-lingual width of the edentulous area measured by CBCT. After confirming the value, tighten the limiting rod fixing screw to ensure the guide hole is located in the central area of ​​the alveolar bone in the buccal-lingual direction of the edentulous area. Use the handle to adjust the position of the locating post so that its distance from the mesial and distal gaps of adjacent teeth is equal, ensuring the guide hole is located in the mesial-distal gap of the alveolar bone in the edentulous area. In the distal central region; use the handle to adjust the direction of the positioning post so that the opening end of the guide hole is aligned with the functional cusp of the opposing tooth; press down the entire device so that the imprint ring below the positioning post leaves a 3mm diameter ring imprint on the alveolar ridge mucosa, then use the matching trephine to cut the mucosa at this point, peel it off, and then reposition it according to the previous steps.
