It preserves maximal tooth structure and helps to restorefunctionandaestheticsinonlyafewclinical visits. In addition, the technique is economical and thepossibleneedforsophisticatedindirectrestora- tioncanbepostponed.Direct-bondingrestorations demand excellent clinical skills. The clinician is re- quired to incorporate various clinical techniques, tips and tricks. Following, I would like to demon- strate a simple technique that I have applied since 2005 in various clinical scenarios and find helpful for the upgrade of clinicians’ restorative skills. TheFlowableFrameTechnique The FFT is a simple restorative technique de- veloped to speed up the placement and simplified confinement of material when restoring challeng- ing anterior aesthetic cases such as large Class IV or Class III defects and diastema closure or reduc- tion. As the name suggests, this technique requires flowable composite resin as frame material, a plastic strip, composite brush and other usual instruments for direct resin restorations. ClinicalstepsintheFlowableFrameTechnique The following steps are to be taken: _Step 1—After the completion of etching, priming and bonding of the tooth surfaces, insert a simple plastic strip to the level of gingival sulcus of the tooth to be restored (Fig. 2). _Step 2—Support the plastic matrix strip lingually with your index finger to create a lingual contour (Fig. 3). _Step 3—Inject the flowable composite resin of de- sired shade (either opacious or translucent) and smooth it to a thin layer with a hand instrument or a composite brush if necessary (Fig. 4). _Step 4—Light cure the flowable composite and remove the plastic strip. A flowable frame is now ready (Figs. 5 & 6). The length, shape and thickness of the flowable frame can be adjusted using the sharp edge of the hand instrument or a diamond point if required. The advantages of the FFT are: _time and cost saving (no direct or indirect mock- up required); _thickness of the layer of restoring materials Fig. 12 Fig. 13 Fig. 14 Fig. 15 Fig. 12_Uniform layer of bonding (FL-Bond) application.
