Modified additive manufacturing and injection molding for diastema closure with an integrated occlusal prop

The Additive Manufacturing and Injection Molding (AMIM) technique was modified by digitally integrating custom occlusal props into a translucent 3-dimensionally (3D) printed injection guide. The design improved mandibular stability, patient comfort, and clinical handling during the placement of multiple anterior composite resin restorations without interfering with the restorative procedure. The technique was demonstrated in a patient treated with direct composite veneers.
