Abstract

The invention provides a dental implant with local functionalization of bionic gradient modulus and a preparation method thereof. The preparation method comprises the following steps: mixing nano-graphene and polyether ether ketone to obtain a mixture, then adding absolute ethanol, and Stir at room temperature, vacuum filter and dry to obtain 1wt% nano-graphene / polyetheretherketone mixed powder; use the same method to obtain 5wt% nano-graphene / polyether ether ketone mixed powder; design a digital model of a dental implant, Then perform function modeling and set the printing path, and then 3D print by mixing powder, and peel off after cooling to room temperature to obtain a dental implant with local functionalization of bionic gradient modulus. The present invention also includes the dental implant prepared by the above method. The invention can produce a dental implant with gradient elastic modulus and regional functional characteristics, and the preparation process is simple, which effectively solves the problems in the prior art that the dental implant does not match the elastic modulus of the alveolar bone and the implant is easy to loosen, etc. .

Description

technical field [0001] The invention belongs to the technical field of dental implants, in particular to a dental implant with local functionalization of bionic gradient modulus and a preparation method thereof. Background technique [0002] Tooth loss is a common disease in the field of stomatology, and implant dentures made of artificial materials are the preferred restoration method for this disease. At present, most of the implant dentures used clinically are made of titanium and its alloys, which have the characteristics of high biocompatibility and superior mechanical properties. However, the excessively high elastic modulus (>100GPa) of titanium and titanium alloys does not match the elastic modulus of natural alveolar bone. This elastic mismatch will cause the metal implant to share more stress when it is stressed with the bone at the same time. , Over time, it may lead to disuse atrophy of bone, this phenomenon is called stress shielding effect, which is one of ...
