Abstract

A laser shaping method for preparing the metallic object used to repair tooth features that combination of 3D laser shaping technique with CAD and CAM to prepare said metallic object directly from metal powder includes generating a 3D CAD model of said object by computer, layering the model by a certain thickness to convert the 3D information to a series of 2D contour information, and laser coating to stacking metal powder by layer according to said contour information until the object is finished.

Description

1. Technical field [0001] The invention belongs to the field of stomatology or biomedical engineering, and relates to a method for preparing oral dentures or denture parts, in particular to a method for preparing oral cavity metal restorations by laser three-dimensional forming. 2. Background technology [0002] Tooth and dentition defect is a common and frequently-occurring disease in the department of stomatology, accounting for about 24%-53% of natural persons. When the disease occurs, fixed restorations are usually selected for restoration by hand-made individual methods. The prosthetics are manufactured using the precision casting method, which is cumbersome, slow, and inefficient, and the number of visits to the doctor is high and the time is long. It is imperative to change the traditional production method. [0003] Since the 1980s, CAD / CAM technology has been introduced into the field of prosthodontics. France, Switzerland, Germany, and the United States have succe...
