Simplifying small but difficult composite restorations

The restoration of anterior teeth is one of the biggest challenges for a dentist, because of the difficulties in color matching, and in recreating natural internal structure of the tooth.
Small median diastemas and small restorations are the most difficult ones to restore, so we will use a new matrix (UNICA matrix) to make the process easy.

smile with broken teeth

Initial smile of the 26 years old patient (shy smile).

broken incisors and bad oral hygiene

Initial occlusion intra-oral view, first of all we should improve oral hygiene by scaling and polishing the teeth, and also by giving instructions for good oral hygiene.

projections of broken teeth

Initial situation, side and occlusal intra-oral view.

occlusal and frontal view before restoration

Initial situation, frontal and occlusal intra-oral view.

rubber dam isolation of anterior sextant

Isolation with rubber dam is very important in order to provide a clean, clear and dry environment.

making margin bevel for composite restoration

All sharp edges were rounded up by diamond football bur.

finishing of the margin bevel with abrasive disc

Smoothening the bevel area with a coarse disc to ensure complete removal of sharp edges and unsustained enamel prisms.

blue rubber dam and teflon isolation

Isolate and protect the adjacent teeth (non working side) with teflon.

etching enamel with orthophosphoric acid

Conditioning the tooth surface with etching 37% phosphoric acid.

rinsing of the etchant from teeth

Rinsing the etching gel by water carefully to ensure complete removal.

brushing of bonding agent

Application of a generous amount of bonding.

light curing of bonding agent on incisors

Light curing of the adhesive.

UNICA anterior matrix for incisor composite filling

Insertion of two Unica matrices and fix it by wedge, its use to give anatomical contour and emergence profile that was the biggest challenge during diastema closure.

UNICA anterior matrix and wedge for class IV restorations

Bending the Unica matrix from palatal side to create the palatal in addition to the proximal wall in one step.

palatal and proximal composite shell

After removing the Unica matrix, the result is a three dimensional enamel composite mould.

composite layering for IV class restoration

Increment of the dentin shade with build-up of the first internal tooth structure.

Compo Brush for incisor composite layering

The restoration is completed by applying a layer of enamel composite and the CompoBrush (Smile Line,Powered by Styleitaliano) for better adaptation.

finishing of composite restorations with abrasive strips

Inter-dental finishing strips to finishing the area interdentally.

polishing paste and goat brush for composite

Polishing paste with goat brush.

rubber cup polishing of composite resin

A rubber cup is used make the surface glossy.

felt wheel for glossy composite

Final polishing with felt wheel.

bleeding gums after rubber dam removal

Immediate frontal intra-oral view, healing of the gum should be satisfying on the check-up appointment, along with the color after rehydration.

gum bleeding after composite restoration

Immediate intra-oral view.

upper incisors composite restorations

Frontal intra-oral view after one week. Aesthetics and function are completely restored.

composite restorations on upper teeth

Final occlusion intra-oral view to show complete color matching.

smile restored with direct composite

Final self-confident smile.

before and after restoring teeth and smile

Comparisons of occlusion and the patient’s smile before and after.

before and after composite incisor restoration

Comparisons of intra-oral frontal view and the patient’s smile before and after. The periapical x-ray shows there is no overhanging of the filling material.

When dealing with aesthetic restorations, an optimal reconstruction of the tooth profile is paramount. In case of diastema closure and class IV restorations, various tools and procedures can help the clinician to correctly restore the emergency profile; among these, the new Unica anterior matrix stands out because of its simplicity and versatility, allowing to quickly and easily restore both cervical and interproximal profiles at the same time, strongly reducing the chair-side time, and bringing aesthetics restorations within everyone’s reach.
