Considerando as preocupações relacionadas ao impacto ambiental e à sustentabilidade associadas ao uso predominante de resinas sintéticas convencionais na impressão tridimensional aplicada à odontologia, torna-se relevante investigar alternativas mais sustentáveis para a manufatura aditiva odontológica. Objetivou-se identificar e sintetizar as evidências científicas disponíveis acerca do uso de resinas biodegradáveis aplicadas à impressão 3D no contexto da odontologia, por meio de uma revisão integrativa da literatura. Para tanto, procedeu-se à busca nas bases de dados PubMed, SciELO e ScienceDirect, sem restrição de idioma ou ano de publicação, sendo incluídos seis estudos após a aplicação dos critérios de elegibilidade. Desse modo, observou-se que as resinas biodegradáveis e biopoliméricas apresentam potencial promissor, especialmente para aplicações laboratoriais e diagnósticas, como a confecção de modelos dentários, com desempenho dimensional satisfatório. Contudo, verificou-se que o corpo de evidências disponível é limitado, predominantemente baseado em estudos in vitro, com heterogeneidade metodológica e ausência de validação clínica. O que permite concluir que, embora as resinas biodegradáveis representem uma alternativa alinhada às demandas contemporâneas por sustentabilidade na odontologia digital, sua incorporação clínica ainda requer investigações adicionais, com estudos padronizados e avaliações de longo prazo que assegurem desempenho, segurança e previsibilidade.
