Abstract
Patient: The patient consulted our department with a chief complaint of aesthetic problems due to anterior tooth discoloration. Since improvement by bleaching was considered impossible, porcelain laminate veneer restorations were performed.
Discussion: Insertion took too long for the patient's satisfaction due to the repetition of color adjustment and recontouring. The veneer preparation area should be limited to enamel; however when dentin is exposed, it is important to treat with primer before adhesion.
Conclusion: In this case, establishing a selection criterion for bleaching, a combined approach was also considered. Although the preparation area is limited to enamel, phosphoric acid etching should be avoided when dentin is exposed. The treatment process should be arranged so as to reduce the manipulation period.
