BONE SUBSTITUTES IN 3D PRINTING OF BONE SCAFFOLDS FOR GUIDED BONE REGENERATION

Purpose: The purpose of this study is to:Highlight the difficulty of using a bone (autologous, allograft) in tissue engineering.Present the different bone substitutes (of natural or synthetic origin used in guided bone regeneration alone or in combination.Describe the different materials and 3D printing techniques of bone scaffolds for bone regeneration. Material And Methods: Research to the Scaffolds and its use in dentistry between January 2012 and December 2020 in Medline via PubMed, Google Translate, Google Library. Results:38 articles were found in the database with the following keywords: bone, 3D regeneration, scaffolds, 3D impression. Conclusion:It is generally accepted that the problems and challenges in the development and application of 3D printing can be solved by printing 3D scaffolds.
