Problems solved by technology

However, the dentin matrix prepared in this study is mouse dentin, which is different from the dentin of other species such as humans. The constructed tissue is dentin, which cannot be designed as a root-shaped scaffold material. Moreover, biological tooth root materials are in the The important bioactive substances in the dentin matrix should not be destroyed to ensure that these bioactive substances can be continuously released from the material to the surrounding environment. Mines to facilitate the co-construction of soft and hard tissues of the pulp and periodontium
At the same time, the regeneration of ectopic dentin used in Guo's study did not discuss the regeneration of alveolar bone.
In summary, this study did not realize the reconstruction of biological root scaffold materials in the true sense.

Abstract

The invention discloses a manufacturing method of a biological tooth root bracket material. The method comprises the following steps of: flushing teeth with phosphate buffered saline (PBS) in a sterile state for three times; removing dental crown parts by grinding with a carborundum disc, and keeping tooth root parts; pulling pulp tissues out of the tooth roots and repeatedly flushing the inside of root canals with physiological saline; gradually expanding the inside of teeth with a dental expander and repeatedly flushing the inside of the root canals with 5 to 17 percent of ethylene diamine tetraacetic acid (EDTA) solution; grinding outer side tissues of the tooth roots by grinding with a dental turbine and constructing a biological tooth root profile as required so as to obtain a bracket with a specific shape; preserving the teeth in the PBS and treating in an ultrasonic oscillator for 3 to 8 times; performing stepped demineralization on a dentine with EDTA with different concentrations in a magnetic stirrer with the rotating speed of between 100 and 500 revolutions per minute so as to obtain a dentine substrate; and preserving the dentine substrate in double-antibody-containing PBS. The biological tooth root bracket material has a tooth root profile, the thickness of 1mm to 3mm, the length of 1cm to 2.5cm and certain tooth inducing capability, comprises a large number of proteins and factors related to the manufacturing of teeth, can release the proteins and factors continuously, can better solve the problem of induction micro-environment, and contributes to application to tooth socket intra-alveolar orthotopic transplantation.

Description

technical field [0001] The invention discloses a construction method of a biological tooth root bracket material. Background technique [0002] At present, the prevalence of tooth loss due to various reasons increases with age, and the prevalence is about 80% in middle-aged and elderly people. Tooth loss and abnormal tooth development seriously hinder the patient's chewing, language and other functions, and cause the patient's appearance deformity, cognitive defects, and psychological disorders, which greatly endanger the patient's physical and mental health. Therefore, it is urgent and arduous to seek effective treatment. task. [0003] At present, the missing teeth are all repaired by artificial prostheses, which have defects such as limited recovery of physiological functions, short service life, damage to normal tissues, etc., and lack of real physiological restoration. Restoration of missing teeth with implants is currently the focus and focus of the treatment of miss...
