This research aimed to describe the metallographic changes in a titanium implant subjected to different temperatures and the evaluation of its potential use as a forensic descriptor. Materials  and methods: Fifteen titanium mini implants with an identification code were made, inserted into pork jaws and subjected to temperatures of 200 ° C, 800 ° C and 1000 ° C, samples were recovered and analyzed were performed by optical microscopy and electron scanning microscopy.  Results: It was possible to characterize the microstructure for each temperature, an increase in the oxide layer was observed with the increase of each temperature.  Conclusion: It is possible to use dental implants as a forensic identifier.","PeriodicalId":52712,"journal":{"name":"Informador Tecnico","volume":"81 1","pages":"113-121"},"PeriodicalIF":0.0,"publicationDate":"2017-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43878862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through this project, we intend to solve this inconvenience and generate a solution with local technology in the Center of Design and Metrology of SENA.  In Colombia, there are not many companies that design and manufacture the elements composing a prosthesis; for this reason, the CDM has been working for approximately five years on the design and adaptation of prosthesis and orthosis with imported components. Thus, we intend to design and implement a 100%-SENA-manufactured ankle articulation for transtibial amputation, which meets the ergonomic and functional needs for patients. This original scientific article gathers the most relevant information regarding a topic affecting our society. Here, we analyze different bibliographic sources described in the existing literature. Using this knowledge, we have created the stages required to write this article, defining revision objectives and making the most relevant bibliographical search, and organizing information according to mind maps in order to write this paper.","PeriodicalId":52712,"journal":{"name":"Informador Tecnico","volume":"81 1","pages":"160-169"},"PeriodicalIF":0.0,"publicationDate":"2017-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45705840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
