Technical Field

The invention belongs to the technical field of medical instruments, and relates to an oral implantation parallel guiding and positioning device.

Background

With the increasing perfection of the oral implantation technology, the implanted denture repair is the best means for treating dentition defects, loss and recovering the oral function under the condition that the conditions (such as the quality and quantity of bone tissues in the edentulous area) are sufficient at present. The ideal implant site requires a distance of 2-3mm between the implants and 1.5mm or more between the implants and the natural tooth. The implant direction is that the long axes of a plurality of implants and the long axes of adjacent teeth are parallel to each other as much as possible, the implant direction directly influences the repair of the superstructure, and the implant direction is parallel to form a common in-place path so as to be beneficial to the repair of the dental crown. But it is difficult to obtain a common seating path in practical clinical practice due to limitations of jaw bone anatomy or differences in planting accuracy. The application of the angle abutment and the personalized abutment can compensate the inclination of the implant, but although the upper parts of the implants can be parallel by the methods, the parts in the alveolar bone are easy to be stressed unevenly, so that the occlusal force cannot be well distributed along the long axis of the implant, the lateral force is increased to cause stress concentration, and complications such as bone resorption, peri-implantitis and the like can be caused clinically. Especially for posterior dental region implantation, due to the visual field limitation and the operation space limitation, operators mostly need to position and orient according to the specific conditions of the operation region by experience, the operation difficulty is high, and deviation is often generated in the application of actual single tooth or multiple tooth missing implantation. At present, the digital planting guide plate manufactured by 3D printing based on oral CBCT scanning data is widely used in oral planting, the accuracy and the safety of planting are improved, the implantation position of an implant can be guaranteed, the final repair requirement is met, the adjacent important anatomical structures cannot be damaged, the personalized design is needed, the process is complex, and the manufacturing cost is high. The existing digital oral implant positioning guide plate needs to be customized, and the processing procedure is relatively complex, so that the requirement of immediate use cannot be met. The existing guide plate can be positioned, the subsequent corresponding position of the jaw teeth can be determined through the orientation rod, observation is needed at any time, and the implant deflection is easy to cause. Most of the existing inventions do not have the function of opening mouth corners and cheek parts, and the operation space is limited. Most of the existing inventions only aim at the parallel device of a plurality of teeth, and can not realize the simultaneous support of single and a plurality of teeth.

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

The oral implant parallel guide positioning device comprises a main guide 1 and a secondary guide 2, wherein the main guide 1 comprises a first orientation column 101, a first retention arm 102, a first orientation hole 103, a first retention hole 104 and a handheld arm 105, as shown in fig. 1 to 5. Wherein, one end of the first fixing arm 102 is connected with the first orientation column 101, the other end is connected with the hand-held arm 105, one end of the first fixing arm 102 is provided with a first fixing hole 104, the middle of the first orientation column 101 is provided with a first orientation hole 103, and the hand-held arm 105 is provided with a groove 106. The auxiliary guider 2 comprises a second retention arm 201, one end of the second retention arm 201 is connected with a second orientation column 202, the other end of the second retention arm is provided with a second retention hole 203, a second orientation hole 204 is arranged in the middle of the second orientation column 202, a retention screw 3 penetrates through the first retention hole 104 and the second retention hole 203 to connect the main guider 1 and the auxiliary guider 2, the retention screw 3 is a spiral screw, and the upper part of the retention screw is a handheld wing 301. The hand-held arm 105 is at a 120 angle to the first retention arm 102. The diameter of all the pilot holes is about 2.3mm, corresponding to the diameter of the reamer shank.

The tool box 4 houses the main guide 1, the sub guide 2 and the set screw 3 of various sizes. The tool box body is designed to be hollow out of stainless steel and can be used for disinfection and sterilization.

The diameter of the directional column is determined based on the distance between the implanted tooth of the implanted area and the adjacent tooth and between the implant and the implant. The distance can be adjusted properly by the retaining screw 3 according to the actual situation. When a single guider is used, a proper size can be selected according to the size of the gap, a proper site can be obtained by directly arranging the proper guider at the missing part, and the implantation direction is determined according to the long axis direction of the guide post and the relation between the guide post and the jaw teeth. When the combination type is used, the main guider 1 and the auxiliary guider 2 are connected through the retaining screw 3 by combination installation. The distance between the main guider 1 and the auxiliary guider 2 is adjusted, and the device can be used after being placed in a planted area. When a single tooth is lost during operation, the main guider 1 or other dimensions can be directly used for guiding and independently using, and the single tooth is placed in an implanted area. According to the requirements of the planted area, proper adjustment is carried out, namely, a pilot drill is used for positioning and orienting, then holes are prepared step by step according to conventional operation steps, and the preparation of the planting sites is completed; if a plurality of teeth are continuously lost, the combined type can be formed according to the width of the implanted area, and the combined type is placed in the implanted area and positioned for drilling. And then preparing holes step by step according to conventional operation steps and completing the preparation of planting sites. After the first hole is positioned and guided to drill, a second hole can be directly drilled; or the upper end of the first reamer can be reserved and sleeved into the guide post, and then the second implantation site is drilled in the direction of the first hole, the parallel position of the second implantation site is more stable and reliable, and if more than two reamer pieces are provided, the reamer pieces can be sequentially positioned according to the method.

The invention also has the advantages that: the hand-held lever has the function of pulling the mouth corner and the cheek part and expanding the operation range. Has different sizes corresponding to different implant diameters, and can select proper product sizes according to requirements. When used in combination, can satisfy the parallel effect of multiple implantable bodies and has the parallel guiding function. The distance between the implant and the adjacent tooth and between the implant and the adjacent tooth can be judged according to the different diameters of the directional columns, so that the positioning site is visualized. Can be used immediately and repeatedly used after being sterilized, and accords with the recyclable concept. The device of the invention is integrally formed, has simple and elegant shape, less fragmentary parts and simple processing procedure. The dental prosthesis has symmetry, can be used by being vertically replaced and inverted according to the position of the edentulous area, is convenient and flexible, can better reflect the long axis direction of the prosthesis, is convenient for contrasting with the jaw teeth and the adjacent teeth, and is beneficial to determining the good implant direction.
