Description
Technical Field
The invention belongs to the technical field of stomatology, and particularly relates to an oral dental implant.
Background
The existing dental implants are mostly made of pure titanium or titanium alloy, and are mostly of a two-section structure and are integrally manufactured in a machining mode. After the advent of Selective Laser Melting (SLM), methods of manufacturing dental implants by 3D printing have been proposed. The advantage of 3D printing can satisfy the requirement of dental implant personalized design manufacturing, but 3D printing has the shortcoming that machining precision is not high. Meanwhile, the 3D printing needs to be applied to support the suspended part, but the support part can also cause a result of poor mechanical properties.
The existing methods of machining dental implants do not allow for the personalized machining of complex structures. The precision of 3D printing manufacturing is insufficient, so that the threads are difficult to match, and meanwhile, the threads are suspended parts and cannot be applied with proper support, so that the mechanical properties of the threads of the machined workpiece are poor. There is then a technique of re-machining after 3D printing, however, since the accuracy of the 3D printing technique is not high, it is difficult to clamp by a jig at the time of machining, and it is difficult to find a coordinate reference point of machining, resulting in wasted time and cost. The condition that mechanical damage appears easily in the junction of traditional structural design's dental implant central screw, and it needs to be planted again after violently extracting, causes great damage to the patient.
