Guia clínico para restaurações de cavidade classe II com resina composta: protocolo prático e estratégias clínicas

Abstract

Introduction: Class II restorations in posterior teeth represent a recurring challenge in clinical dental practice, especially regarding the achievement of adequate proximal contacts, marginal adaptation, and anatomical reconstruction. In this context, the correct execution of operative procedures and the appropriate selection of materials and matrix systems are determining factors for clinical success. Objective: To develop a technical-demonstrative clinical guide for Class II composite resin restorations, addressing the operative procedures, materials used, and clinical strategies related to achieving predictable restorative outcomes. Methodology: This is a descriptive study with a technical-demonstrative approach associated with a narrative literature review. The review was conducted using electronic databases, focusing on evidence related to Class II restorations and matrix systems. The practical stage was performed on a dental model containing a Class II cavity in tooth 36, using circumferential and sectional matrix systems. The clinical procedures were carried out in a standardized manner and documented through sequential photographic records. Results: It was possible to describe a detailed restorative protocol, highlighting the clinical procedures, materials used, and relevant operative strategies, including the use of matrix systems to obtain adequate proximal contacts. Conclusion: The proper execution of operative procedures, associated with the correct selection of materials and matrix systems, contributes to greater predictability and quality of Class II restorations, making the proposed guide a useful educational resource for clinical practice.
