Description

 Maxillary sinus and bone picking}

The present invention is one of the devices used in the dental implant procedure, when the maxillary posterior portion is small in thickness can not be implanted implant fixture, the maxillary sinus elevation and bone extractor to elevate the maxillary sinus membrane at the same time to implant the implant fixture It is about.

Implants are originally a substitute that recovers when human tissue is lost, but dental implants refer to implanting artificial teeth.

In order to replace the lost tooth root (root), a tooth root made of titanium and other materials that are not rejected by the human body is planted in the bone where the tooth falls out and the artificial tooth is fixed to restore the function of the tooth.

In the case of a general prosthesis or denture, the bone of the surrounding tooth is damaged over time, but the implant does not damage the surrounding dental tissue, but the same shape and function as the natural tooth does not cause tooth decay.

Such implants can be placed on the spongy alveolar bone immediately according to the patient's condition, and when the implant fixture (artificial root) cannot be implanted due to natural absorption and artificial loss of the side bone and height of the spongy alveolar bone. Implant fixtures were implanted 3-6 months after bone graft.

According to various factors of the patient, the implant fixture must obtain initial fixation at the time of the procedure, so that bone fixation between the fixture and the spongy alveolar bone must be made.If the implant fixator is not initially fixed, remove the existing implant fixture. Longer implant fixtures or coarse implant fixtures were re-planted or bone grafted for a certain period of time, resulting in patient discomfort, cost, and procedure time. have.

The maxillary sinus membrane is one of the important parts of the human body that works in conjunction with the respiratory tract (nose) to control humidity in the nasal cavity and to control resonance when talking.

Therefore, the implant procedure has been complicated to preserve the maxillary sinus and maxillary sinus alveolar bone to the maximum.

For example, to remove the maxillary sinus membrane without damaging the maxillary sinus membrane carefully, the bone adjacent to the maxillary sinus membrane is carefully removed, the maxillary sinus membrane is separated, the bone graft is implanted, the implant fixture (artificial root) is planted, and the artificial tooth is placed on top of the implant fixture. Insert has been fixed.

When the implant fixture is fixed to the bone and the bone thickness is thin during the procedure, it is difficult to implant the implant fixture has been developed a device for harvesting bone by bone extractor.

Korean Patent Application Publication No. 10-2007-87900 discloses a hollowed out part of the collecting part, and a bone extraction drill and a collecting container are formed with a sawtooth-shaped tip and an outer wall oblique line so that the collected bone is contained in a fiber plastic container. It can be seen that.

Conventionally, to extract bones, the bones of the maxillary sinus and the maxillary sinus are not damaged, the bones are carefully removed to implant and other bones are implanted therein, and the implant fixture (artificial root) is planted and the artificial implant is placed on top of the implant fixture. In order to preserve the maxillary sinus and maxillary hypocortical alveolar bone as much as possible during implantation, and to obtain bone for implantation, the complex procedure was used to solve the above problems with a simple device and method. The invention is to be solved.

In order to solve the above object, when the implant fixture can not be implanted because the bone thickness is small in the maxillary posterior molar, implantation of the implant fixture is possible by elevating the maxillary sinus membrane and maxillary sinus low cortical alveolar bone at the same time as the bone extraction. It is a problem solving means to achieve the present invention to provide a maxillary sinus elevation and bone extractor that is an improved device structure to be crushed and implanted in the elevated space.

The present invention solves the problems (bone damage and bone necrosis) caused by frictional heat generated during bone removal by introducing coolant into the coolant inlet groove, and at the same time rounding the cut and coating a diamond powder having a diameter of micrometer, By elevating a certain area in a circle without perforation and removing the bone at the same time, the bone is transplanted into the transplanted space and the elevated maxillary sinus membrane is placed on the upper part after the procedure to minimize damage to the maxillary sinus membrane and the maxillary sinus alveolar bone. At the same time, it is possible to harvest bones, so that the collected bones are used as autografts.

In order to achieve the above object, the present invention is a shaft (1) having a connection groove 10 on one side, and a cylindrical body (bone extraction unit) connected to the lower portion of the shaft (1) and having a space therein. Consists of 20, the body (bone collection unit) 20 is a plurality of cooling water inlet grooves 21 formed perpendicular to the rim side and the body (bone collection unit) 20 protrudes in a spiral in the middle side of the side (20) The present invention relates to a maxillary sinus elevation and a bone extractor composed of a damaged bone removal blade 22 and a cutting part 23 coated with a diamond powder having a diameter of micrometer on the lower edge of the body (bone extracting part) 20. .

The present invention elevates the maxillary sinus membrane and maxillary sinus alveolar alveolar bone to a predetermined area, and at the same time, the collected bone is implanted in the elevated space, and then implanted implant fixture (artificial root), and then implant implant upper portion By implanting and fixing the artificial tooth in the implant, the maxillary sinus membrane and maxillary sinus alveolar alveolar bone at the maximum preservation, and implanted bone is related to the maxillary sinus elevation and bone harvester improved structure to be implanted in the implanted space.

In general, the maxilla is composed of cortical alveolar bone, spongy alveolar bone, maxillary sinus membrane and maxillary sinus hypocortical bone, and the upper part of the maxillary sinus membrane is provided with a pupil (space) and the maxillary sinus membrane is associated with a respiratory organ (nose). It is one of the important parts of the human body that controls the humidity in the nasal cavity and controls resonance when talking.

Therefore, when cutting the alveolar alveolar bone with the device of the present invention, the maxillary sinus membrane and the maxillary sinus low cortical alveolar bone are pushed up to the upper pupil (space part) without tearing, and when the removed alveolar alveolar bone is filled with artificial bone and modified bone, In the present invention, when the spongy alveolar bone is thin, the implant fixture (artificial root) cannot be planted, so that the bone of the patient's body is obtained in order to obtain the amount of bone (bone) necessary to form the artificial bone. Rather than harvesting bones from other parts, harvesting bones from damaged spongy alveolar bone is used because it reduces time and economic pain.

Hereinafter, the present invention will be described in detail with reference to the following Examples.

Next, the rotary motor is driven, and a coolant pipe is introduced into the coolant inlet groove 21 to cool the frictional heat generated during rotation, and is cut by the cutting unit 23 and cut to the damaged bone removal blade 22. At the same time, the surface damaged bone was removed from the side wall of the alveolar alveolar bone, and at the same time, the maxillary sinus membrane located under the cortical bone was lifted by the cutting part 23, and bone was collected inside the cylindrical mechanism. (See Fig. 5).
