The patient presented with lower black triangles following orthodontic treatment with aligners. He was very self-conscious about the appearance of the black triangles, which were visible and caused food to become trapped during meals. Seeking a minimally invasive solution, he opted for Bioclear composite restorations on his lower six teeth to address his concerns.
The Black Triangles were measured, and anatomical mylar Bioclear matrices were selected, and tried in to ensure the proper emergence profile with the surrounding gingiva and papillae.A rubber dam was applied, and the teeth were discolosed to allow thorough biofilm removal using aluminum trihydroxide powder and Aquasol solution (Aquacare). No tooth preparation was necessary.

Dicolsing the teeth prior to biofilm removal
Bioclear Black Triangle matrices were positioned on the first tooth both mesially and distally to close the black triangles on each side. Small Black Triangle matrices were used for this case, with shield matrices placed on adjacent teeth to protect the surrounding spaces. Bioclear Injection Moulding was carried out using 3M™ Scotchbond™ Universal Plus Adhesive, warmed 3M™ Filtek™ Supreme Flowable, and 3M™ Filtek™ Supreme XTE Universal body paste composite in shade A2 The first central incisor was then sculpted and refined using small 3M™ Sof-Lex™ coarse and medium discs. This procedure was subsequently repeated for the second central incisor and the lateral incisors
