Description

Universal surgical guide kit for dental implant placement for surgical implants using surgical guides

The present invention relates to an implant surgical kit for a surgical guide used in a dental implant procedure using a surgical guide, including a drill guide tube, a drill, and an implant mount. When using the surgical kit according to the present invention in the use of implant procedures can be applied to any implant system by the implant manufacturer, it is possible to accurately and efficiently guide the drilling and implant placement, and also the implant depth (depth) and implant The internal angle can be adjusted to make the prosthesis immediately. In other words, the upper prosthesis prepared before surgery is very useful for making teeth immediately after mounting the implant.

Dental implants are also referred to as artificial teeth or third teeth. Implant is a dental technique called artificial tooth implantation, which refers to a dental procedure that restores the function of natural teeth by implanting a biocompatible implant body in the area of the tooth defect.

Conventionally, after anesthesia, the gums are first incised, the gums are opened, the patient's bones are exposed, and the bones are visually checked while drilling (drilling). It was. 1-2 weeks after suture, the suture is removed and after 3-6 months have elapsed, the abutment is made by floating the bone of the lower pillar of the implant, and the tooth shaped crown is made by floating the bone of the abutment. I went through the process of making teeth. To do this, the patient had to visit the dentist several times, usually more than seven times, and the treatment took a long time.

Recently, by applying digital radiology technology, the patient's bone condition is precisely analyzed in advance in the 3D image before the implant procedure to determine the implant placement position and orientation, and to prepare the surgical guide to implant the implant in this direction. Implants can be operated using. When using this surgical guide, it is not necessary to cut the gum to expose the patient's jawbone, and the implant can be accurately placed through the small opening formed in the gum without looking at the bone.

With the accuracy of the surgical guide, the implant abutments and crowns can be placed directly on the lower pillar of the implant. The entire time taken to create an implant-driven tooth is reduced from months to just one day, which greatly reduces the discomfort of patients who need to see the dentist frequently, and the patient has his or her teeth in the area where the tooth is lost in one day. I can go home, so I can solve the loss of feeling that I do not have teeth as soon as possible. As a result, the number of patients and the length of treatment required for the implant procedure are no longer shortened.

Currently, there are many companies around the world that manufacture and sell surgical guides. Most of these companies offer surgical kits for implant placement using only surgical guides of specific companies. For example, Osstem Implant Company offers Quick Guide® surgical kits, Megagen Implant company AnyGuide® surgical kits, and Nobel Biocare offers Branemark System Guided® surgical kits.

On the other hand, some companies offer universal surgical kits for implant placement using other surgical systems, but their use is limited to surgical kits that can only guide drilling. For example, Materialize Dental is offering a product called Universal SurgiGuide®, but it is a kit with drill guides by size and can only guide drilling by implant manufacturer. There are limitations in that it is not possible to accurately guide different types of implant products to horizontal, vertical and implant internal angles.

Furthermore, cybersex Med (Cybermed) used in In2Guide during marketed ^TM of products, Ido come only could be provided to guide kit yeoseo, only Drilling in various kinds of drills, too accurate implant manufacturer of various kinds of implants per product There is a limit to the horizontal, vertical and implant internal angles that cannot be guided.

Yet, it can be applied to any implant system by implant manufacturer in the surgical procedure using the surgical guide, and it is possible to accurately and efficiently guide the drilling and implant placement, and to control the implant depth and the internal angle direction of the implant. There is no known surgical surgical kit for implants.

The success or failure of surgery in conventional dental implants is overly dependent on the experience and skill of the surgeon. The dental surgeon determines the type, number, location, implant angle, and implant depth of the implants, and these decisions can vary depending on the experience and proficiency of the surgeon. Furthermore, even if the above conditions of the dental implant are determined, it is very difficult for the conditions to be equally implemented in the actual surgical procedure. This is because, even in the case of surgery by the same surgeon, the operation result may be changed every time. In order to solve this problem, it is necessary to operate the implant using the surgical guide. When using this surgical guide, even inexperienced surgeons can accurately place implants. However, there are limitations when using a surgical guide, which requires the use of a specific company's implant system and a specific company's surgical guide implant kit. Therefore, because the products are different from company to company, it is necessary to purchase a surgical kit for a surgical guide of a specific company as a product of a specific company to use, which is not preferable in terms of cost. In addition, companies that provide surgical kits for surgical guides are very limited.

Some companies also offer universal surgical kits that allow implants to be placed using surgical guides, but as described above, their use is limited to surgical kits that can only guide drilling.

Therefore, it can be applied to any implant system by each implant manufacturer, can accurately and efficiently guide drilling and implant placement, and can control the implant depth and the direction of implant internal angle so that the prosthesis can be manufactured immediately. The development of a universal implant surgical kit is needed.

The inventors of the present invention solved the above problems by providing a universal guide surgical kit for surgical guide, consisting of a drill guide tube, a drill and an implant mount.

By using a universal implant surgical kit including a drill guide tube, a drill, and an implant mount according to the present invention, any implant system for each implant manufacturer in an implant procedure using a surgical guide It is also possible to provide a universal implant surgical kit that can be applied to the drilling and implant placement accurately and efficiently, and can also control the implant depth and the implant internal angle direction.
