Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of surgical guides, and in particular to a stacked oral implant surgical guide system. Background Art

[0002] With the continuous development of stomatology, the technology of oral implant restoration of edentulous / missing edentulous has become more and more popular, and the demand for oral implant surgery is becoming increasingly difficult to meet the growing needs of patients. After 2000, digital implant technology has become increasingly mature, which will be an effective way to solve this problem, especially with the popularization of CBCT, which enables preoperative diagnosis and implant planning based on patient CT image information and related restoration information, with the help of professional implant design software; through the dental implant surgery guide template, the implant plan formulated before the operation is accurately applied to the implant surgery and immediate restoration to assist doctors in completing the treatment. This method is called an oral implant surgery guide.

[0003] However, previous oral implant surgery guides can only provide single implant positioning or osteotomy positioning. If the above two operations need to be combined during the surgery, it is necessary to "wear-surgery-removal-replacement-surgery", and during "removal" and "replacement", it is very easy to cause position movement due to damage to the positioning holes and soft tissue edema and deformation, which may cause the guide to be unable to be worn.

[0004] At present, there are many operations that need to be combined in oral implant surgery. At the same time, additional alveolar bone osteotomy, tooth / residual root extraction, bone augmentation, maxillary sinus internal / external lifting, temporary denture wearing, etc. are often performed. The surgical guide of a single procedure cannot meet the needs of other additional surgeries. If the guide is replaced in each step, it cannot be ensured that the guide that only meets the oral state and environment before the operation can perfectly match the oral state and environment that have been changed by the previous operation. During the operation, the guide is replaced according to the needs. Each time the guide is replaced, the original position is maintained by the retention hole left in the jawbone when the original guide is fixed. The retention hole will become larger and have tolerances due to the repeated insertion and extraction of the retention pins, especially for patients with low osteoporosis density. For example, patients with bone types of three to four need navigation implantation, which is completely unsuitable for such repeated insertion and extraction and fully digital navigation osteotomy, implantation, tooth wearing and other multiple processes are concentrated under navigation positioning. Secondly, each time the guide is replaced, it takes time to find a matching original retention hole, and there may be three-dimensional deviations during the period. Furthermore, the guide plate requires the operator to practice repeatedly to complete the operation, which is not conducive to the use of beginners. Fourthly, the existing guide plate cannot guide the wearing of the restoration on the same bone base guide plate. Summary of the invention

[0005] To this end, an embodiment of the present invention provides a stacked oral implant surgery guide system to solve the problem in the prior art that it is difficult to perform multiple implant surgeries in the oral cavity continuously because the traditional oral implant guide is single and cannot support complex surgeries.

[0006] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0007] A stacking oral implant surgery guide system comprises a base guide and at least two groups of working guides, each group of working guides is used for performing different surgeries, the base guide is provided with an arc-shaped stacking cavity adapted to the gums, the base guide is sleeved on the gums, the bottom of each working guide can be attached to the top of the base guide, and a locking member is provided between the base guide and the working guide for detachably fixing the two.

[0008] Furthermore, the locking component is a latch, a first fixing hole extending from top to bottom is provided on the working guide plate, a second fixing hole is provided on the base bottom plate, the first fixing hole and the second fixing hole are connected to each other and are both inclined, the latch is inserted into the first fixing hole and the second fixing hole to fix the working guide plate and the base guide plate, and one end of the latch extends from an end of the second fixing hole away from the first fixing hole.

[0009] Furthermore, a fixing structure is coaxially fixed to the outer side wall of the latch, and the diameter of the fixing structure is larger than the diameter of the first fixing hole.

[0010] Furthermore, a clamping block is fixedly provided on the top of the base guide plate, and a clamping slot is provided on the bottom of the working guide plate, and the clamping block is clamped and matched with the clamping slot.

DETAILED DESCRIPTION

[0026] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] A stacked oral implant surgery guide system, such as Figure 1 and Figure 2 As shown, it includes a base guide plate 1 and a working guide plate 2, both of which are arc-shaped and arranged horizontally, and an arc-shaped stackable cavity 11 is opened inside the base guide plate 1, and the stackable cavity 11 is adapted to the upper and lower gums in the cavity, that is, the base guide plate 1 can be sleeved on the upper and lower gums of the oral cavity through the stackable cavity 11. There are multiple groups of working guide plates 2, and each group of working guide plates 2 is used for different oral surgeries. These working guide plates 2 are divided into multiple different types such as tooth-supported, mucosa-supported, bone-supported, and mixed-supported according to the fixing method, and each type has multiple working guide plates 2 with different functions and structures, and these working guide plates 2 are all applicable to this application. And this application is applicable to the case of two or more working guide plates 2, and the effect is not obvious for a single working guide plate 2.

[0028] The side of the base guide plate 1 close to the working guide plate 2 is its top, and the side of the working guide plate 2 close to the base guide plate 1 is its bottom. When the implant surgery is performed on the lower gum in the oral cavity, the base guide plate 1 is located below the working guide plate 2, and when the implant surgery is performed on the upper gum in the oral cavity, the base guide plate 1 is located above the working guide plate 2. Now, take the implant surgery on the lower gum as an example for explanation:

[0029] The side walls of the base guide plate 1 located on the inner and outer sides of the gums are provided with mounting holes 12, which are through holes and communicate with the gums. There are three mounting holes 12 located on the outer side of the gums and located in the middle and both sides of the base guide plate 1, and there are two mounting holes 12 located on the inner side of the gums and located on both sides of the middle of the base guide plate 1. A mounting sleeve 13 is coaxially fixed in each mounting hole 12. When fixing the base guide plate 1, the fixing pin is inserted into the mounting sleeve 13 of the base guide plate 1, and one end of the fixing pin is inserted into the bone of the gums for fixing. The mounting holes 12 located on the outer side of the gums are arranged horizontally, and the mounting holes 12 located on the inner side of the gums are arranged obliquely to facilitate the insertion of the fixing pin.

[0030] A first wavy surface 14 is provided on the top of the base guide plate 1, and a second wavy surface 21 is provided on the bottom of the working guide plate 2. Both the first wavy surface 14 and the second wavy surface 21 are uneven surfaces, and the surface of the first wavy surface 14 fits tightly with the surface of the second wavy surface 21 to ensure the accuracy of the alignment between the working guide plate 2 and the base guide plate 1, and to check whether there is any deviation between the manufacturing process of the base guide plate and the working guide plate and the preliminary design causing mismatch.

[0031] A rectangular block 15 is fixed on the top of the base guide plate 1, and a rectangular slot 22 is provided on the bottom of the working guide plate 2. The block 15 extends from the top of the base guide plate 1, and the block 15 is inserted into the slot 22. There are three groups of blocks 15 and slots 22, two groups of blocks 15 and slots 22 are located on the outside of the gums and symmetrically arranged along the middle of the base guide plate 1, and the last group of blocks 15 and slots 22 are arranged on the inside of the gums and in the middle of the base guide plate 1. After the block 15 is engaged with the adjacent slot 22, the base guide plate 1 is accurately positioned on the working guide plate 2.

[0032] like Figure 3 and Figure 4 As shown, a first fixing hole 23 is provided on the working guide plate 2, which passes through from top to bottom, and a second fixing hole 16 is provided on the base bottom plate. The first fixing hole 23 and the second fixing hole 16 are connected to each other. A latch 24 is inserted into the first fixing hole 23 and the second fixing hole 16 to fix the working guide plate 2 and the base guide plate 1, and one end of the latch 24 extends out from the end of the second fixing hole 16 away from the first fixing hole 23, and the second fixing hole 16 is provided on the block 15. A fixing structure 241 is coaxially fixed to the outer wall of the latch 24, and the diameter of the fixing structure 241 is larger than the diameter of the first fixing hole 23. The first fixing hole 23 and the second fixing hole 16 are arranged in the same direction to prevent loosening and displacement.

[0033] The base guide 1 made according to the original oral state and environment is fixed on the patient's oral position during the operation plan. It does not need to be removed or moved from the start of the operation to the completion of all operations including additional operations. The working guide 2 for performing each additional operation is combined one by one on the base guide 1 that has been fixed in the patient's mouth according to the needs of the operation and the order of operations to guide the operator during the operation.

[0034] During the implantation operation, the base guide plate 1 is sleeved on the gums and fixed in the oral cavity by a fixing pin. The working guide plate 2 is placed on the base guide plate 1 and fixed by inserting a pin 24 into the first fixing hole 23 and the second fixing hole 16. After the implantation operation is completed, the pin 24 is pulled out, and the working guide plate 2 can be directly taken down to replace another working guide plate 2, and then the pin 24 is inserted into the new working guide plate 2 and the base guide plate 1 for fixing. The working guide plate 2 and the base guide plate 1 are matched by the block 15 and the slot 22, the first wave surface 14 and the second wave surface 21 to ensure accurate alignment between the two. After the fixation is completed, the next implantation operation is performed. After the implantation operation of the working guide plate 2 is completed, the pin 24 is removed again and another new surgical guide is replaced. The base guide plate 1 is always fixed on the gums, so that various complex implantation operations can be performed conveniently and accurately. A fixing structure 241 is provided to ensure that the insertion and removal of the pin 24 is more labor-saving.

[0035] The base guide 1 and the working guide 2 are contoured by scanning the oral cavity of each patient, and the surgical position and method are designed based on the CBCT data, and then they are completed by 3D printing. When performing surgery on each patient, the base guide 1 and the working guide 2 can be fully adapted to the gums in the patient's mouth to ensure the accuracy of the surgery and achieve personalized customization.

[0036] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
