Abstract (original English)

Background Regenerative dentistry aims to reinstate, fix, renew, and regrow tissues within the oral and craniofacial domain. Existing regenerative methods are based on insights into tissue biology or disease processes that lead to tissue degradation. However, achieving complete and functional Tissue regeneration remains a primary challenge in real-world medical scenarios. Aim The review focuses on the application of bioprinting techniques for rejuvenating intricate Oral and craniofacial tissues, such as craniofacial bone, periodontal ligament, cementum, dental pulp, temporomandibular joint cartilage, and whole teeth. Methods Bioprinting, a cutting-edge technology in regenerative dentistry, strives to create entirely new Functional tissues and organs. This approach merges principles from engineering and biology to produce three-dimensional biologically operational constructs containing bioactive substances, Living cells and cell clusters using automated bioprinters. The review summarizes the outcomes achieved through bioprinting techniques in both in vitro (laboratory experiments) and in vivo (Studies on living organisms) experiments. Result The emergence of this innovative tissue engineering technology has yielded highly promising outcomes during the experimental stages. Conclusion These promising experimental results necessitate replication through human clinical trials to asc
