The pursuit of the perfect smile, as popularized by media and social networks, emphasizes white, well-aligned teeth with minimal spacing. This close contact between teeth enhances aesthetics and promotes dental health and longevity.

Disruption of this contact leads to diastemas, gaps that are more common in the maxillary arch, particularly the upper incisors. While maxillary anterior diastemas do not impair function, they often detract from the smile's aesthetic harmony, drawing attention to the gap.

This concern frequently prompts patients to seek dental intervention, as they perceive diastemas as a major factor compromising their smile and quality of life. Treating maxillary anterior diastemas presents a challenge for dental surgeons, who must balance patient aesthetic desires with the biological and mechanical requirements of an effective treatment plan.

This work defines maxillary anterior diastemas in adults, detailing their classifications and main etiologies. It examines the impact of diastemas and discusses various treatment options, focusing on orthodontic and fixed prosthetic solutions.
