Vol. 16 – Number 63 – 2023 Aligners Page 115-133 Practical guide for manufacturing aligners in house – Part 3: printing models, post-processing, thermoplasticization, improvement and clinical management Bernardo Quiroga Souki¹ Raiane Machado Maia² Gabriel Maia Azevedo² Lílian Dayse Fróes Tavares³ Carlo Bosoni4 Abstract Following the virtual planning of orthodontic movements using suitable platforms and the resulting exportation of multiple digital models of sub-setups, the laboratory phase begins to produce in house aligners. This phase involves the utilization of 3D printing technology to fabricate models using photosensitive resin, followed by additional steps of washing and post-curing. The models are then prepared for printing using a range of thermoplastic polymer laminate choices. After this, they are meticulously trimmed, refined, sterilized, and subsequently, disseminated to the intended recipients. The current part 3 of the tutorial will focus on the practical concepts involved in the in house production of aligners.
