Design method of fixed anchorage for assisting invisible correction

Abstract

The invention discloses a design method of a fixed anchorage for assisting invisible correction. The design method comprises the following steps: 1) obtaining digital tooth-alveolar bone model fitting; 2) designing an invisible appliance main body; 3) determining the positions of fixed anchorage and traction components; 4) designing a traction bonding part; and 5) designing an anchorage positioning part. According to the invisible orthodontic system provided by the invention, the design and manufacturing of the fixed anchorage are integrated into the whole invisible orthodontic tooth movement scheme, and the optimal anchorage implantation position and force application mode are determined by virtue of three-dimensional finite element analysis, so that the implementation of complex tooth movement is facilitated to the greatest extent under the existing conditions; and meanwhile, a side effect caused by a counter-acting force acting on the non-designed moving teeth is avoided through the provided stable anchorage.

Description

technical field [0001] The invention relates to a design method of fixed anchorage, in particular to a design method of fixed anchorage for auxiliary invisible correction. Background technique [0002] Malocclusion is the third most prevalent disease in stomatology, and its incidence is as high as 60-70% in the general population. The traditional fixed appliance has formed a systematic theory and treatment method, which can meet the treatment requirements of most cases. However, because the appliance is fixedly bonded to the tooth surface, it affects oral cleaning, eating and aesthetics, and most of them are designed and manufactured in a standardized manner, so it is difficult to apply force accurately to each tooth. In recent years, removable invisible aligners are basically invisible after wearing and do not affect tooth surface cleaning and eating, so they have high aesthetics and comfort. The personalized design through the 3D digital model to gradually realize the en...

Problems solved by technology

However, unlike the three-dimensional digital personalized design of invisible orthodontics, the implantation of implant anchorage is still operated by the doctor's individual experience, which is basically completely separated from the design and manufacture of invisible orthodontic appliances. It lacks accurate positioning and standardized operating procedures, and its implementation The force method is not optimized and unified with the invisible aligner

Therefore, the operation is difficult and the popularization is difficult, resulting in limited application of invisible orthodontics in complex tooth movements
