Midline diastema closure with direct composites

Direct composites offer an advantage over other options due to its shortened treatment time & non-invasive nature

Wed. 14 June 2023


A report published in the Journal of American Dental Association (JADA) estimates that around 1.6% to 25.4% of adults from various age groups and populations have midline diastema. Various treatment options, like orthodontics, direct composites, and indirect veneers, are in use for midline diastema correction. Direct composites offer an advantage over other options due to their shortened treatment time. One of the major advantages of direct composites over indirect veneers is their non-invasive nature. This case series discusses various techniques for diastema closure with direct composites.


In this article, a case of midline diastema in a 24-year-old male patient that was closed in a single appointment with direct composite build-up is discussed in detail. This case report presents a step-by-step approach toward composite build-up under rubber dam isolation. Z350 Filtek from 3M was used with a universal bonding agent.

The success of these restorations depends on following the protocols for bonding and its integration with the surrounding soft tissues. Direct composites if handled well, by a skilled clinician, offer the best modality to transform the smile in a single visit with minimally invasive protocols.
