V-II-V planting and repairing tool box

Technical Field

The application relates to the field of medical instruments in stomatology, in particular to a V-II-V implantation repair tool box.

Background

Clinically, patients without an odontognathic jaw who suffer from maxillary atrophy and have serious bone defects in the sinus floor of the maxillary posterior dental area generally need to perform effective bone augmentation (maxillary sinus lift or direct alveolar crest parietal augmentation) if dental implant restoration is to be completed. But maxillary edentulous patients who are partially intolerant to bone grafting, present a significant challenge to dental implant restorative treatments. The doctor who takes Paulo Malo as the first provides an 'All-on-4' dental implantation treatment concept, and researches prove that the survival rate of the implant in the scheme is high and the clinical effect is satisfactory. "All-on-4" is a treatment plan for immediate fixation and restoration of the edentulous jaw by implanting 4 dental implants, wherein 2 vertical implants are in front and 2 oblique implants are in front of the maxillary sinus. 4 implants were concentrated between the anterior walls of the bilateral maxillary sinuses. With certain cantilevers, a fixed restoration between the first molar of the patient to the first molar on the contralateral side can be restored. But the existence of the cantilever beam can increase the biomechanical and mechanical risks of the prosthesis and the implant.

Guiding, positioning and fixing in the adjustable V-II-V guide plate opening: a pioneer drill is used for deepening an implantation site positioning mark, bone is removed appropriately and crest tops of alveolar ridges are leveled as required, the assembly is adjusted according to the implantation site dental position mark of the restoration guide and the size and radian of dental arches, an adjustable V-II-V guide plate is guided to be in place, the adjustable V-II-V guide plate is preliminarily fixed by a middle fixing nail, and the restoration guide positioning mark point and an adjustable V-II-V guide plate pre-formed dental position point lantern ring are basically kept consistent when the adjustable V-II-V guide plate is in a near-far position; after the center is fixed, the three-dimensional direction of the planting site of the wing plate is adjusted and positioned, and the three-dimensional direction of the front oblique planting and the front tooth area vertical planting body of the maxillary sinus is adjusted and positioned; after the matching is finished, the cuspids on two sides of the adjustable V-II-V guide plate and the fixing nails on the left side and the right side of the posterior tooth area are fixed, and the in-situ guiding in the mouth of the adjustable V-II-V guide plate is finished.

Finishing the planting of the adjustable V-II-V guide plate guide spare hole: after the guide plate is guided to be in place, confirming and adjusting the position relation of the guide plate according to the clinical planting design scheme; the V-II-V integral repair scheme is adopted to prepare the planting cavity by adopting an implant cavity squeezer in a tool box according to the designed implantation site and bone under the guide of a guide plate, the adjustable V-II-V guide plate is taken down, and the prepared planting cavity is further expanded according to the bone density after the implantation site, the peripheral bone mass and the angle direction are determined to be correct. During the preparation of the planting cavity, the depth of the planting hole is accurately measured by using a planting cavity depth detector. The preparation of the planting cavity can also be finished by bare hands according to preoperative design. After the preparation of the site is finished, the fixed point and the three-dimensional direction of the zygomatic bone base part are determined by using a zygomatic implant detector.

Implanting an implant: selecting an appropriate kind of implant from the tool box; confirming the length of the implant with a patrol nurse, opening the outer package of the implant by the patrol nurse, taking out the implant, carefully opening the sterile plastic package, and carefully pouring the implant filled with the sterile inner-layer package on a sterile operating table to avoid the contact with the sterile inner package and the falling pollution of the inner-layer package; fully exposing an operation area in the mouth, stabilizing an opening position of a patient, holding an implant by a manual or motorized implanter by an operator, taking out the implant from a sterile titanium tube package, and slowly rotating and implanting various implants according to a preoperative designed three-dimensional angle and an anatomical marking point from an implantation site; ideal initial stability is achieved when finally implanted; adjusting the inner hexagonal plane to be consistent with the buccal surface; mounting a covering screw for embedding, planting and healing, mounting a composite abutment and an abutment healing cap for exposing and healing, and instantly transferring an impression to finish instantly repairing under the condition of better initial stability; when the implantation is needed, the implanter needs to be stabilized and implanted according to the design angle and the anatomical landmark point, so that the implantation angle is prevented from deviating.

Resetting the soft tissue valve, and aligning and tightly suturing; the final restoration of the dental implant is completed 3-6 months after the operation.
