Description

Technical Field

[0001] The utility model belongs to the technical field of special equipment and facilities for dental implants, and specifically relates to a guided oral implant hole preparation guide plate and an autogenous bone chip collection system. Background Art

[0002] In recent years, the demand for dental implants in China has grown rapidly, and oral implant technology has also achieved unprecedented development. The existing dental implant surgery process is to cut the gums, turn over the gingival flap, use a ball drill to locate the point on the alveolar bone, and then use twist drills from fine to coarse to expand the hole step by step, and finally obtain an implant cavity shape that matches the length and diameter of the implant. In this process, the doctor prepares the positioning and cavity expansion manually. Usually, due to the limitations of the intraoral field of view and the patient's mouth opening, it is not easy to place the instrument to the ideal axis and position, resulting in a certain deviation between the implant result and the ideal planned implant site.

[0003] In order to obtain a relatively ideal implant site, there is a procedure of implantation guided by an implantation guide designed before surgery. The design process of the implantation guide is as follows:

[0004] First, an impression is made inside the mouth to replicate the intraoral morphology, and the jaw morphology is scanned using CBCT (cone beam CT). The two are combined to obtain the morphological data of the soft and hard tissues inside the mouth.

[0005] Secondly, the ideal implant site is simulated on the implant guide design software, and a guide ring is made at the ideal site to limit the depth and direction of the implant drill;

[0006] Finally, the guide ring is connected to the support structure covering the tooth surface, and then 3D printing is performed to produce an implant guide plate placed on the tooth surface that can limit the implant site;

[0007] The process of preparing the hole using implant guide surgery is:

[0008] First, put the implant guide into the patient's mouth and confirm from the observation window that the implant guide is completely in place;

[0009] Next, a circular incision is made in the gingiva within the hole limited by the guide ring;

[0010] Finally, use a handle guide ring with the same outer diameter (matching the inner diameter of the guide ring) and inner diameters from small to large to nest it in the guide ring on the guide plate, pass the reamers with diameters from small to large through the middle of the handle guide ring, and limit the direction of the reamer hole through the friction between the short cylindrical structure on the upper part of the reamer and the inner wall of the handle guide ring, thereby preparing the implant cavity. By replacing the handle guide ring, reamers with increasingly larger diameters can pass through the hole in the middle of the handle guide ring, gradually expanding the implant cavity, thereby completing the preparation of the implant cavity.

[0011] In the prior art, the use of implant guides for surgery does solve the technical problem of obtaining a relatively ideal implant site. However, the following technical problems also exist in the actual application process:

[0012] The height of the guide ring is usually limited by the mouth opening, and is generally about 5mm. However, the length of the implant drill is usually more than 10mm, and the guide ring does not provide sufficient guidance for the implant drill.

[0013] The guide plate covers the implant area, making it difficult for cooling water to enter the prepared hole area. Currently, cooling is generally performed by injecting water into the cooling hole with a syringe or injecting water into the cooling water channel on the implant handpiece. The cooling efficiency is low, and the injection point of the cooling water is not accurate, which can easily cause overheating of the implant prepared hole area and cause bone burns.

[0014] Traditional implant preparation procedures and existing implant surgical guide systems grind the alveolar bone in the cavity into debris during the preparation process, which is then flushed out with the flow of cooling water, making it impossible to recycle the autologous bone, resulting in a serious waste of autologous bone (a valuable biological resource).

[0015] Based on the above technical problems existing in the prior art, the utility model proposes a guided oral implant hole preparation guide plate and an autogenous bone chips collection system. Summary of the invention

[0043] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Example

[0044] like Figure 1 As shown, the guided oral implant hole preparation guide and autogenous bone chip collection system comprises:

[0045] A guide plate device 1 is clamped on the maxillary tooth or mandibular tooth where the tooth to be implanted is located, and a guide ring 11 for guiding the implant drill is fixedly provided on the guide plate device 1;

[0047] an alveolar bone debris collection device 3, connected to the cooling device to collect the alveolar bone debris;

[0048] As a specific embodiment, the guide plate device 1 includes a guide plate body 12 and a cooling water inlet 13 and a cooling water outlet 14 opened on the guide plate body 12, wherein the cooling water inlet 13 and the cooling water outlet 14 are respectively opened on both sides of the prepared bone hole, wherein the cooling device is connected to the cooling water inlet 13 to supply sterile saline, the water temperature is 4 degrees Celsius, the power of the supply is pumped, and the cooling water outlet 14 serves as an outlet for the saline after it flows through the prepared bone hole;

[0049] The guide plate device 1 is made of resin and is formed in one step by 3D printing. Specifically, an impression is made in the mouth to replicate the intraoral morphology, and the morphology of the jaw is scanned by CBCT (cone beam CT), and the two are combined to obtain the morphological data of the soft and hard tissues in the mouth; the ideal implant site is simulated on the implant guide design software, and a guide ring is made at the ideal site to limit the depth and direction of the implant drill; the guide ring is connected to the support structure covering the tooth surface, and then 3D printing is performed to produce the guide plate device 1 placed on the tooth surface to limit the implant site;

[0050] The alveolar bone debris collecting device 3 is made of engineering plastic or metal.

[0051] As a preferred embodiment, the guide ring 11 is connected to a guide ring extension 111, wherein the guide ring extension serves to heighten (extend) the guide ring, improve the guide plate accuracy, and increase the height of the guide ring to improve the guiding effect of the implant guide plate on the implant drill. In actual operation, the working edge of the implant preparation drill (with a diameter larger than the drill handle) is hidden under the guide plate device 1, and the working end of the drill is close to the top of the alveolar ridge. The smooth handle of the drill passes through the guide ring extension 111. Before the guide plate device 1 is in place, the end of the smooth handle of the drill is connected to a protective cap to prevent the drill from loosening. After the guide plate device 1 is in place, the protective cap is removed, and the end of the smooth handle of the drill is connected to the adapter, which is connected to the head of the implant mobile phone. When the implant mobile phone rotates, it drives The drill needle for preparing the hole rotates, and the smooth handle of the drill needle is restricted by the guide ring 11 and the guide ring extension 111, so that the direction of the implant hole can be accurately aimed, and the cutting of the guide ring 11 can be avoided.
