Resumo
Objetivo: Discutir, com base na literatura científica atual, as indicações clínicas, os protocolos e as evidências de longevidade dos laminados cerâmicos executados sem preparo dental (noprep) ou com preparo minimamente invasivo, avaliando suas vantagens, limitações e impacto na estrutura dental remanescente. Revisão bibliográfica: Os laminados cerâmicos sem preparo ou com desgaste ínfimo representam avanço significativo na Odontologia restauradora contemporânea, preservando esmalte dental e reversibilidade do tratamento. O sucesso dessas modalidades depende de seleção criteriosa de casos, planejamento digital integrado, escolha do material cerâmico adequado — com destaque para cerâmicas feldspáticas e disilicato de lítio ultrafinos — e domínio dos protocolos adesivos. Estudos de acompanhamento de 5 a 12 anos demonstram taxas de sobrevivência superiores a 90%, desde que respeitadas as indicações e contraindicações. O preparo minimamente invasivo, limitado ao esmalte, garante maior resistência adesiva, menor sensibilidade pós-operatória e melhor prognóstico a longo prazo quando comparado a preparos que invadem dentina. Considerações finais: A abordagem no-prep e o preparo minimamente invasivo para laminados cerâmicos constituem alternativas clinicamente viáveis e biologicamente responsáveis, respaldadas por evidências científicas crescentes. A seleção criteriosa de casos e o rigor técnico são determinantes para o sucesso e a longevidade desses tratamentos.
