Currently, there are few studies on lyophilized bovine bone as a biomaterial for the manufacture of bone reconstruction implants [4] [8] [9] and these are usually focused on their manufacture, sterilization or mechanical comparison with other materials. The implants manufactured in this biomaterial have a main advantage over implants made of other materials, osteoinduction and osteoconduction, which cause the complete regeneration of the implant, eliminating the need for a second surgery to remove them. The main objective of this research article was to design and implement a guide for the manufacturing of HA2.7 screw implants; this manufacturing line includes the steps of material preparation, machining, cleaning, packaging and sterilization. In order to verify each of these stages, cytotoxicity tests, analysis of implant textures, chemical analysis, dimensional analysis, reproducibility and repetitiveness analysis of the process, and surface roughness analysis were used until the implantation of the screw as a fixation of fasciae latae implants. The surgery is based on an extraarticular repair of the anterior cruciate ligament rupture in a dog, where the behaviour of the screw was observed as its osseointegration in time until the patient recovered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
