10 I I MICD _ diastema closure (dentine, enamel and opacious group) can be predicted; _as with the silicone template method, an opaque halo, mamelons, and translucent areas in the proximal and incisal areas can be created; _smooth palatal surface is achieved with minimal finishing; _smooth adaptation of the restorations can be achieved even in the gingival sulcus; and _it is the most suitable lingual frame creation tech- nique for diastema reduction or closure. _Material selection and clinical steps for diastema closure Material selection for diastema closure should be guided by optical properties (light transmission and diffusion characteristics) and tissue responses of the materials (restoration in diastema closure normally touches the gingival tissue and sulcus). Amongstthevariousmaterialsavailable,Giomersare amongst the latest category of micro-hybrid light- cured restorative materials and are touted as the true hybridisation of glass ionomers and composite resins,astheyhavethefluoridereleaseandrecharge of glass ionomers and the aesthetics (shade, polish and optical properties), handling and physical prop- erties of composite resins. Giomer restorative and adhesive systems have good bio-compatibility13 and have been reported not to result in long-term post operative sensitivity.14 They have also been found to possess anti-plaque formation properties.15 Hence, giomer direct-restorative materials and adhesive systems were selected to close the MD in this case.
