Diastema closure cases pose significant challenges, particularly in the aesthetic domain where imperfections are highly noticeable. Advances in technology and ongoing scientific research on materials and techniques have simplified daily clinical practice, yielding predictable and effective outcomes. Achieving a natural shape in anterior teeth relies on factors such as outline, light reflection, surface texture, and gloss. In this article, the essential guidelines for achieving a natural diastema closure using the bioclear method will be outlined.

Initial situation.
Close-up view showing diastema with old overhanging composite in the middle and cervical area. The removal of the overhang composite is necessary to facilitate rubber dam placement.

Rubber dam isolation is a necessary step for ensuring a moisture-free working environment during adhesive procedures. Subsequently, sandblasting with 25 um aluminum oxide was employed.

Matrix placement.
Using clamp b4 for better retraction is essential. Following that, double bioclear bands DC 202 are placed for diastema closure. These bands effectively separate the space into two equal parts.

Bonding and curing.
After acid etching and bonding the teeth, the emergence profile is crafted using flowable composite. Subsequently, it is light-cured using an Eighteeth CuringPen (Eighteeth, Changzhou, China) capable of reaching deep areas of the composite.

Composite placement.
Following the creation of the emergence profile for both teeth and the placement of a wedge to ensure adequate separation, composite adaptation is performed for the first tooth using 3M Body Shade A2 composite. Subsequently, light curing is carried out. Then, one band is removed, and the process is repeated in a similar manner for the second tooth.

Composite placement.
After getting the proximal profile for both teeth and removing the second band, the final layer was placed in labial surface with enamel shade.

Final situation under rubber dam.
Immediately after adding the enamel shade, reshaping is initiated using a coarse disc, followed by finishing with enhance finishing burs. Finally, polishing is carried out using a Jota polishing wheel and Lucida polishing paste (Diashine) for the final glaze.

Diastema closure demands meticulous attention to detail and the utilization of advanced techniques. By employing the bioclear method, one can achieve not only aesthetically pleasing results but also predictable and long-lasting restorations.
