Embodiment 1

[0053] Such as figure 1 As shown, the preparation method of a low-elastic-modulus titanium-based jaw implant in this embodiment mainly includes 6 steps, namely: obtaining CT-scanned jaw cross-sectional image data, and obtaining a reconstructed three-dimensional digital model of the jaw , Design and obtain the digital model of the porous structure of the jaw implant, obtain the processing file of the sliced ​​layered section data, prepare the jaw implant by selective laser melting technology, and perform surface treatment on the implant. Each step is described in detail.

[0054] 1. Obtain the cross-sectional image data of the jaw from the CT scan

[0055] In this embodiment, CT examination equipment is used to scan the patient's jaw, and the scanning area is from the upper edge of the orbit to 2 mm below the mandibular angle, so as to ensure the integrity of the data. The scanning voltage is 120kV, the scanning current is 170-220mA, and the scanning layer thickness is 1-1.5m...

Abstract

The invention discloses a low-elasticity-modulus titanium-based jawbone implant and a preparation method of the implant. The preparation method mainly comprises the six steps that CT-scanned jawbone section image data are obtained; a rebuilt jawbone three-dimensional digital model is obtained; a jawbone implant digital model of a multi-hole structure is designed and obtained; a machining file of slice layered cross section data is obtained; the selective laser melting technology is adopted for preparing the jawbone implant; and surface treatment is carried out on the implant. The implant is used for treating a patient with jawbone defects, and the CAD digital design technology is used in the design of the implant; and jawbone repairing individualized design and multi-hole support structure design are combined, and through the selective laser melting technology, the low-elasticity-modulus titanium-based jawbone implant is prepared. The implant can meet the individual needs of the patient, and meanwhile can reduce the elastic modulus; and the problems of stress concentration and stress shielding of a traditional jawbone implant are solved, the preparation time is shortened, and the machining difficulty and the production cost are reduced.

Description

technical field [0001] The invention relates to the field of artificial bone implant research, in particular to a titanium-based jawbone implant with low elastic modulus and a preparation method thereof. Background technique [0002] The jaw is an important part of the oral and maxillofacial system, not only the bony support of the maxillofacial region, but also the structural basis of chewing, swallowing and language functions. Once jaw deformities and large-area defects are caused by inflammation, external trauma, tumors or developmental deformities, it will not only lead to maxillofacial deformities, but also affect basic functions such as chewing, swallowing and language in severe cases, thus increasing the number of patients. Physical and psychological pain, leading to a decline in the quality of life of patients. However, due to the complex structure of the jaw, the repair of large-area defects of the jaw has always been the focus and difficulty of clinical surgery. ...
