Introduction. Midline gap (diastema) is a space between two teeth, commonly between two incisors. The treatment can be provided by orthodontic, conservative (restorative) or prosthetic methods.Aim. The aim of the study was an assessment of using direct composite restoration in aesthetic closing of diastema.Material and methods. The space correction between teeth was performed among female and male adult patients with diastema of 3 to 6 mm. The microhybrid resin composite was used for the composite build-ups with a help of celluloid or silicon matrix due to its good handling properties and shade matching, and polishability properties.Results. Depending on the size of diastema, the partial or total closing was done to achieve the cosmetic effect. The obtained clinical results were highly assessed both by dentists and patients. It was possible to obtain optimal aesthetic results with resin composite restorations only.Conclusions. The simple closure of diastema with direct composite reconstructions can result in successful outcome and patient's satisfaction.
