Sodium perborate with 20% hydrogen peroxide was applied for 3 weeks using a developed artificial pulp chamber, with peroxide replacements provided every week. Composite resin restoration was performed, followed by a microtensile test. Then, specimens were analyzed using a stereomicroscope and scanning electron microscopy (SEM). Data were submitted to Kruskal-Wallis and Dunn tests (P < .05). The bond strength of nonbleached teeth was similar to the groups restored after 7 days of bleaching (P < .05). The lowest bond strength values were seen in groups restored immediately after bleaching (P < .05). In all groups, there was a considerable predominance of adhesive fractures. Delaying the final restoration of teeth submitted to nonvital bleaching by 7 days increased the bond strength. The immediate restoration of bleached teeth after using 10% sodium ascorbate or 5% sodium thiosulfate for 10 minutes showed unsatisfactory results. Irrespective of the dentin protocol applied before adhesion, bond strength values will be satisfactory when delaying the final restoration and unsatisfactory when immediately performing the final restoration.

Two types of surgical stents were designed: one to aid in cutting a prefabricated ACL into the desired shape for the defect to be regenerated, and one to assist in the positioning and fixation of the resulting laminates. These stents enabled the clinician to regenerate a horizontal defect with reduced surgical time and increased precision and safety during laminate fixation.
