Making class IV restorations predictable
A clinical cases by our Community member Dr Osama Shaalan.
One of the challenges many dentists face when working on anterior teeth is the lack of predictability. This happens both in class IV restoration cases and in multiple veneering cases. The main challenges are the final restorations shade, shape, and the entire process. So how can we make our results predictable and repeatable in our daily practice? Well, since Styleitaliano introduced their simplified protocols, the workflow had become easier, just as getting the desired outcome. The new techniques, instruments, and materials facilitate the entire restorative workflow and make it easy and simple. In this article I will show you how we can be predictable and repeatable with a magic combination, when dealing class IV restoration or any anterior composite restoration by using the simplified two-shade system (WDB), the specifically designed UNICA matrix, and the all-in-one LM ARTE Solo instrument by LM dental. That’s not all, also polishing has been simplified, thanks to the Lucida™ star-shaped felt and the one-step polishing paste.
A young patient came to the clinic with a three-year-old fracture, asking to restore this tooth.
Retracted view. The initial situation with a left central fracture at the incisal 1/3, it extends more palatally making very thin enamel edge labially. and the tooth responds well to thermal stimuli. Before the treatment, we did scaling for lower incisors and removed the calculus.
Color matching and analysis must be performed before rubber dam isolation when the teeth are fully hydrated, otherwise, there is a high risk of mismatching color by choosing one that’s whiter than appropriate.
Rubber dam isolation is mandatory to work a clean, contaminant-free environment.
In this specific case, a 1.5 -2 mm bevel was created using a yellow-band flame diamond bur. If the tooth were bright and opaque and small fractures there would be less or no need to hide the cavity margin, so no bevel would be required.
The White Dental Beauty CompoSite system only features one enamel shade, which has been designed to blend flawlessly with all the Si universal shades. Thanks to its calibrated translucency and opalescence properties, it is ideal for a two-layer technique or to simply characterize the incisal edge.
Using the Unica matrix (by Polydentia) to restore the proximal wall. The matrix can be stabilized with a wedge if necessary. In this case, My Custom Resin (Polydentia) was injected and cured to keep the matrix in the desired position.
After application of the final enamel layer, before finishing.
The perio diamond bur from the Styleitaliano Finishing kit is ideal to even the surface at low speed, and to correct shape and contour.
The Lucida™ Star Felt is a disposable polishing device. Latch mandrels for the Lucida Star Felt may be autoclaved and reused. The DiaShine Lucida™ Paste is completely water soluble. These two allow for a single-step polishing of composite restorations.
The final situation, with correct shape, shade and contour, and a glossy surface.
The smile of a happy patient.
By the introduction of new simple techniques, materials, and tools, we can simplify our daily work and make it predictable and repeatable. Following the Styleitaliano philosophy can decrease chairside time for the dentist and the patient, making such procedures affordable and minimally invasive for the patients.
