Dental implant having different surface treatment areas

Abstract

A dental implant having different surface treatment areas is formed by a coarse screw tooth zone, a dense screw tooth zone, a neck ring portion, a top portion and a conjugative pore, the coarse screw tooth zone is composed of screw teeth having a wide pitch, the surface of the coarse screw tooth zone is sandblasted, and the sandblasted surface is etched by an acid to form holes having different sizes; the dense screw tooth zone is composed of screw teeth having a narrow pitch, and the surface of the dense screw tooth zone is etched by the acid to make a plurality of small holes distributed in the acid-etched surface; the neck ring portion is positioned at the upper edge of the dense screw tooth zone, and the surface of the neck ring portion is etched by the acid to make a plurality of small holes distributed in the acid-etched surface; the top portion is positioned at the top edge of the dental implant, and the surface of the top portion is etched by the acid to make a plurality of small holes distributed in the acid-etched surface; and the conjugative pore is positioned at the inner edge of the top portion, and is a blind hole provided with a positioning surface and a female screw. The above structure is helpful for the easy screw-in, the reduction of osteocyte necrosis and the improvement of the gripping capability of osteocytes in order to realize osseointegration.

Description

technical field [0001] The invention relates to a tooth root implant with different surface treatment areas, especially a tooth root implant that facilitates screwing, reduces osteocyte necrosis and improves bone cell grasping ability to achieve osseointegration. Background technique [0002] In recent years, in the advertisements broadcast on TV channels, whether it is related to tooth cleaning or peripheral products, there has been an increase. On the one hand, it can remind people to pay attention to tooth cleaning, and on the other hand, it also shows that people The number of people with tooth decay or periodontal disease is increasing year by year due to neglect of cleaning and maintenance of teeth. General periodontal disease or tooth decay can be treated initially, but if it is too severe, it is necessary to extract the teeth and then install dentures to restore the chewing function. At present, there are only fixed dentures and removable dentures in the way of inst...

Problems solved by technology

However, in the process of implanting the artificial tooth root into the alveolar bone, it is often encountered that the osseointegration effect of the artificial tooth root and the bone cells in the alveolar bone is not good enough, which leads to failure. The surface of the artificial tooth root has a roughening process, but this roughening process causes the tooth front on the root to be damaged. When the damaged tooth front encounters the dense layer in the alveolar bone, it will be difficult to lock in, and Forcibly apply force to lock in, increase friction, generate high heat and cause necrosis of surrounding bone cells, and fail to achieve the purpose of osseointegration; The artificial tooth root is completely submerged under the alveolar bone below the gingiva, and the top surface of the artificial tooth root will be slightly lower than the alveolar bone surface at the bottom of the gingiva by 1mm to 2mm. This is because clinically, when the artificial tooth root is implanted, it will generally cause a little bone atrophy The situation, the implantation method under consideration, but because the top surface and the collar of the artificial tooth root are generally polished, although in order to ensure the biological width, the bacteria in the oral cavity will not go down along the artificial tooth root and then infect the bone cells, resulting in osseointegration failure. However, it is indeed impossible to effectively allow the bone cells in the alveolar bone to grasp through the sunken implantation method, resulting in the exposed root of the tooth after implantation with the lowering of the gums, which will affect the stability of the artificial tooth root. In severe cases, it may even be necessary to re- Carry out another artificial bone repair operation
