Description

3D prints and plants baffle suitable for interlock space is not enough

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a 3D printing planting guide plate suitable for insufficient occlusion space.

Background

At present, an implant guide plate becomes a common oral implant auxiliary mode in clinic, and by means of the mode, the position and the depth of an implant are virtually preset according to the conditions of the inside of the mouth and CBCT of each patient, a static guide plate is printed, an implant drill point is guided, and the implant is placed, so that the technical sensitivity can be greatly reduced, the operation time is shortened, and the implant guide plate becomes a most widely applied guide technology in the field of oral medicine.

When the conventional implant guide plate is applied, the guide plate is firstly positioned in the mouth, and then the turbine and the implant drill bit are vertically inserted into the guide ring for cavity preparation, so that a certain amount of vertical space is required for using the implant guide plate to accommodate the guide plate, the drill bit and the turbine, wherein the thickness of the guide plate guide ring is about 6mm, the bottom of the guide ring is about 5mm away from the crest of the alveolar ridge, the thickness of the drill bit is about 20mm, and the thickness of the turbine head is about 11mm, so that the vertical space of 42mm is required in total if the guide plate is used.

The statistics of the existing research show that the opening degree of the front teeth of healthy people is about 37-42mm, and if the situation of tooth missing occurs, according to the average clinical crown height of the people, about 8-10mm, a vertical space of 45-52mm can be provided, so that all guide plate components can be accommodated, and the completion of the implantation operation is ensured. However, for patients with lesions such as posterior dental area or temporomandibular joint disorder and joint coercion, the mouth opening is often insufficient, the vertical space which can be provided is only 30-35mm, the requirement of the implant guide plate cannot be met, and after the implant guide plate is worn, a 30mm drill point and a 30mm turbine are not inserted vertically in enough space. In clinical, the baffle drill point can't take one's place, can't obtain normal guide supplementary, then can't reach the purpose of accurate implantation to the not enough patient in interlock space, especially the not enough back tooth in interlock space disappearance patient, the degree of openness is little, available space is little, the planting site is located the blind area more, put into intraoral back with turbine and drill point, the unable accurate direction and the site of judging of art person, if unable static guide that uses, implant direction, great deviation often can appear in the degree of depth, or the alveolar nerve under appearing, the damage of important anatomical structure such as maxillary sinus.
