Abstract

Aim: This review aims at analyzing the literature available regarding the properties of the novel Tera Harz resin introduced to manufacture direct printed aligners in terms of its mechanical characteristics, accuracy, and cytotoxicity.
Utilizing the databases of PubMed, Scopus, and the Cochrane Library, a search for publications published up until February 2024 was conducted by applying the search phrases ("3D printed" OR "three-dimensional printed") AND aligner AND (polymer* OR material* OR resin* OR technopolymer*).
Results: There were 620 records found in the first search. 220 studies were reviewed after duplicates were eliminated. A total of 196 complete texts were screened based on the title and abstract. 90 full-text papers had their eligibility evaluated. The qualitative synthesis contained 16 studies.
Conclusion: With its ideal characteristics, the new shape memory resin has the potential to be a viable replacement for thermoformed aligners, offering greater accuracy and force delivery. The gathered data is still only somewhat reliable and quantitatively scarce. It is necessary to do more research to assess the therapeutic efficacy of these new materials.
