Description

Guiding tube for dental implantation operation

Technical Field

The utility model relates to a medical treatment technical field of department of stomatology, concretely relates to guiding tube is used in tooth implantation operation.

Background

The immediate tooth implantation technology is a technology for implanting an implant into a fresh tooth extraction pit to repair the extracted tooth after the tooth which cannot be continuously reserved due to the problems of trauma, periodontal disease, decayed tooth and the like is extracted, and compared with the traditional delayed implantation operation (the implantation operation is performed after the tooth extraction pit is completely healed after 3-6 months), the immediate tooth implantation technology can shorten the treatment time, and the tooth extraction operation and the implantation operation are completed at the same time, so that the secondary wound caused to a patient is avoided, particularly when the repair is performed after the tooth extraction in an oral cavity front American area, the immediate tooth implantation repair technology can avoid the tooth missing period of the patient and reduce the adverse effects on the physiology and the psychology of the patient caused by the tooth missing. Because the immediate dental implantation restoration technology has such outstanding advantages, the technology is widely applied to the restoration treatment of clinical edentulous in recent years. However, in clinical practice, the technical sensitivity of the operation is high, which is mainly embodied in that the operation with extremely high precision requirement needs to be completed in an environment with limited operation space and visual field in the oral cavity, because the deviation of sub-millimeter level may cause irreversible damage to important anatomical structures adjacent to an operation area, such as tooth root, nerve, blood vessel, sinus cavity, nasal floor and the like, and cause corresponding functional disorder, or because the three-dimensional position of the drilled and ground implant implantation fossa is not good, after the implant is implanted, the upper part of the implant is difficult to repair, even the implant repair fails, and the technique is often used for the aesthetic region repair of anterior teeth, if the precision is not good, the nasal floor may be damaged, such as the oral cavity and nasal cavity are penetrated, even the nerves of the nose and the palate are damaged, so that the oral local sensory abnormality of the oral cavity is caused, and a series of aesthetic complications are caused, such as the implant is deviated from the fossa labial side, so that the bone on the labial side is weak and absorbed, the gingival margin retreats, and even the implant fails to be exposed, in addition, the control of the precision in the technical operation is difficult, because the operation needs to drill and grind the implant implantation nest on the slope for extracting the tooth nest by using a drill needle, the drill needle is easy to slide along the slope and deviates from the set drilling and grinding route, and uncontrollable deviation occurs.

At present, the scheme capable of better solving the difficulty is a digital planting guide plate technology, and the technology can accurately convert a virtual drilling operation scheme performed in three-dimensional software before an operation into actual operation. The implant guide plate mainly comprises a base plate and a guide tube, wherein the base plate part can be formed by a 3D printing technology and used for fixing the whole guide plate system in a patient mouth, the guide tube part is inserted in a channel reserved on the base plate, the channel contains three-dimensional information such as the position, the angle, the depth and the like of an implant planned according to a repair scheme before an operation in an alveolar bone, and after the guide plate is positioned in the patient mouth in the operation, an operator only needs to insert a drill into the guide tube and can drill and grind a needed implant implantation pit hole by drilling step by step under the guidance of the guide tube. Among them, the deviation between the three-dimensional position of the implant socket actually drilled in the alveolar bone under the guide of the guide plate and the three-dimensional position of the implant socket planned before the operation is the guide accuracy of the implant guide plate, and studies have shown that the drill accuracy of the guide plate guide is in positive correlation with the length of the guide tube, in negative correlation with the distance from the lower end of the guide tube to the drilling point of the drill point on the alveolar bone, and in negative correlation with the depth of the drilled and ground implant socket, but the guide tube length used in clinical practice is short at present, taking the widely used guide type zelman implant system as an example, the guide tube used in the immediate implant operation of anterior teeth is still insufficient 1/3 of the length of the guide needle, and in the guide immediate implant operation, the lower end of the guide tube is far from the drilling point on the slope of the extraction socket, and further, because the existence of the extraction socket requires the implantation of a relatively long implant body to obtain good initial stability, this means that a relatively deep implantation socket with a length suitable for the implantation socket needs to be drilled and ground, and these realistic factors make the precision of the current implantation guide plate in guiding the immediate implantation operation not ideal, and postoperative complications occur occasionally, so that improvement on the prior art is urgently needed to further improve the precision and safety of the implantation guide plate in guiding the immediate dental implantation operation.
