The invention discloses a local deformation method of a denture surface based on topology reconstruction, comprising the following steps: A. calculating the influence area of ​​a drag point according to denture model data; B. deleting the drag point in the influence area of ​​the drag point The topological information of all points other than the hole is formed to form a hole, and the information of all points on the hole boundary is stored; C. According to the drag point and the above hole boundary point information, the hole is repaired through the deformation operation. The method of the present invention uses the projection distance as the topological distance on the denture model, which is closer to the projection distance of the real topological distance, and uses the interpolation method to reconstruct the topology as the result of local deformation, completely avoiding the self-intersection of the triangular mesh of the denture model question. As a local deformation method of the denture surface based on topology reconstruction, the invention can be widely used in the field of denture restoration.

Metal titanium and titanium alloy are widely applied to implants of oral prosthodontics, orthopedic surgery and plastic surgery at present, but have the problems of having poor osseous integration capability and being prone to have bacterial infection after implantation. The invention discloses a titanium and titanium alloy surface micro-nano structure modification method, and aims to improve theosseous integration capability and antibacterial capability of titanium and titanium alloy surfaces. The micro-nano structure modification method is characterized in that a femtosecond laser processing technology is adopted, the polished titanium alloy surface is ablated to form a micropost periodic structure with the spacing and the depth not greater than 200 microns, nanotubes with the diameterssmaller than 200 nm are prepared on the micropost periodic structure in an anodic oxidation mode after further acid pickling, and then annealing heat treatment is carried out to obtain a final sample. According to the method, the surface with a micro-nano structure can be prepared on the titanium and titanium alloy surfaces, and the titanium and the titanium alloy with such surfaces have good biocompatibility and antibacterial capability.

The invention relates to a parametric surface reconstruction method for discrete data of dentures, comprising the following steps: expressly reconstructing a triangular mesh model of dentures by using circumscribed sphere criterion; and mapping vertices of triangular mesh models of dentures to On the unit square of the plane parameter domain; according to the inverse mapping technology, the regular sampling points on the unit square of the plane parameter domain are mapped to the triangular mesh model; the regular sampling of the triangular mesh model is obtained, and the denture is obtained by using the B-spline surface interpolation algorithm B-spline surfaces. The invention can shorten the period of oral restoration and alleviate the pain of oral patients.

The invention belongs to the field of medical equipment, in particular to a device for removing metal studs in dental prosthetics. The existing metal stud removal equipment needs manual operation, and manual hand-held instruments are difficult to stabilize the position directly, and the position is prone to shift, which is harmful to patients. The damage is very serious, the following scheme is proposed, which includes a support frame, a fixing groove is opened on the top of the support frame, a threaded rod is slidably installed in the fixing groove, a drive nut is threaded on the threaded rod, and the top of the threaded rod A mounting plate is fixedly installed, and an adjustment slot is opened on the top of the installation plate, and an adjustment column is installed rotatably in the adjustment slot, and a connection slot is opened at one end of the adjustment column, and a telescopic column is slidably installed in the connection slot. The invention has reasonable structure and convenient operation. The removal device can automatically remove the metal studs, and can stabilize the position during the removal, is less prone to position deviation, and causes less harm to patients.
