Description
Technical Field
The invention relates to the field of dental implant tools in stomatology, in particular to a tool box for lifting inside a maxillary sinus.
Background
As more and more people lose the teeth, the implant teeth are gradually accepted as the internationally accepted 'third pair of human teeth', more and more people begin to receive the implant teeth, and the benefits brought by the implant teeth are also felt. When the maxillary posterior tooth is missing, the maxillary sinus floor is often insufficient in height for alveolar ridge absorption, and the implant may penetrate the maxillary sinus wall and mucosa. In order to implant the implant, it is often necessary to implant some substitute of synthetic bone to lift it into position so as to ensure that the implant is in the maxilla, a procedure known as maxillary sinus lift. Maxillary sinus lifting includes external lifting via fenestration of maxillary sinus lateral wall and internal lifting via alveolar ridge apical approach. The principle of the lifting in the maxillary sinus is that the maxillary sinus floor mucosa is lifted and separated to form a cavity, and the hyperosteogeny is caused by the generation of fibrin clot. The maxillary sinus external lifting operation can lift mucous membrane under direct vision, but the operation wound is larger, and complications are easy to occur after the operation.
Because promote postoperative complication few, healing time short, easy operation in the maxillary sinus, and it is littleer to the patient's damage, the patient is more accepted. The clinical top-flushing maxillary sinus lifting operation is to prepare a bone hole, namely an implant hole, through the crest of an alveolar ridge, then use an ejector to impact and push a sinus floor bone into the sinus to lift the sinus floor mucosa, and select and fill bone substitutes or directly implant the bone substitutes into the implant according to the lifted height. However, when the bone hole is prepared at the crest of the alveolar ridge, the depth of the implant hole cannot be accurately controlled by a common bone drill, so that the maxillary sinus floor bone is too thick or directly drills through the maxillary sinus floor cortical bone and the mucosa, and when the maxillary sinus floor bone is too thick, the bone punch needs to apply a large force when pushing the maxillary sinus floor bone into the sinus, so that the mucosa is easily broken due to excessive force. In addition, the top flushing device in the prior art is not provided with a blocking result, so that the control and the grasping difficulty of the lifting amount are high, and the operation efficiency and the operation effect are influenced.
Chinese patent No. CN 204133625U discloses a spiral maxillary sinus internal lifting device and an internal lifting system, which comprises a positioning guide plate, a lifting rod and a ring block gauge; the positioning guide plate is provided with a guide hole corresponding to the planting pit, a threaded sleeve is fixed in the guide hole, the outer wall of the threaded sleeve is matched with the guide hole, and the inner wall of the threaded sleeve is provided with internal threads; the lifting rod consists of a stress part, a check ring and a working part, the stress part and the working part are separated by the check ring, the working part comprises a thread section, a head part and a connecting section, the thread section is meshed with the internal thread of the thread sleeve, and the ring sleeve block gauge is provided with the internal thread; in the operation process, the top surface of the guide hole is used as a positioning reference surface, and the length of the working part of the lifting rod is greater than the distance from the top surface of the guide hole to the bottom of the planting nest; inner lifting height H of lifting rod is L-H1-Hz. A spiral maxillary sinus internal lifting system is composed of the maxillary sinus internal lifting device and a hole preparation tool, wherein the hole preparation tool comprises a drill bit and a pressing plate. The invention has high lifting precision, and can be used without damaging the planting pitThe advantages of retention of the inner lifting device are achieved. However, the lifting system is complex in structure, complex in operation, easy to move for the positioning guide plate and low in practicability.
Chinese patent No. CN 207949918U discloses an maxillary sinus internal lifting device, which comprises a handle, an adjusting nut, a mandril and a crank; the upper end of the handle is connected with a crank, and the upper end of the crank is screwed with a mandril through an adjusting nut; it also comprises a protective sleeve; the protective sleeve consists of a silica gel antibacterial sleeve and blood-sucking cotton; the outer wall of the silica gel antibacterial sleeve is provided with blood-sucking cotton; the top end of the silica gel antibacterial sleeve is provided with an inward concave surface matched with the upper end surface of the ejector rod. Can adsorb the blood that oozes in the planting hole that is equipped with to, avoid the work end to push up the in-process and appear skidding, alleviate the sterile burden of instrument simultaneously, the practicality is stronger. However, the lifting device has no stop ring, and is easy to be lifted excessively, so that the mucous membrane is broken.
