Every day, professionals who work with esthetics are faced with the challenge of meeting patients expectations who longs for a perfect smile, where every detail must show harmony and naturality. In this context, composite resin reanatomization is widely indicated for small corrections of color and shape in one or more dental elements, for diastema closure and sometimes for correction of small dental misalignment. The case report presented here discuss the planning and treatment for the esthetic and functional improvement of the dental units 1.1, 1.2, 2.1 and 2.2, by making direct restorations in composite resin. The patient sought the Faculty of Dentistry of UFBA in search of esthetic treatment, reporting dissatisfaction with the smile. During an evaluation, the thickness and size of the upper back teeth were dissonant, besides of the interincisal diastema and a discrete gyroversion of the lateral incisors, which together compromised the esthetic area of the smile. Therefore, the proposed treatment for solving this clinical situation was direct esthetic rehabilitation with composite resin in units 1.2 to 2.2. After obtaining the study models, it was accomplished diagnostic waxing and silicone guide as auxiliary resources on the planning and restorative stage. Nanoparticulate composite resins were used, making a stratification technique to obtain a harmonic result. The treatment was able to reproduce the esthetic and natural appearance of the teeth, through a conservative alternative, fast and with an excellent cost-benefit relation when compared to the indirect techniques.
