Advanced Effects (part 2)
The palatal surface represents, in conjunction with the incisal edge, the mechanical area of the anterior teeth. In recent years, conservative restoration of the palatal surfaces of abraded and/or eroded teeth, as in the three-step technique developed by Vailati, has become very popular.
An article by Jordi Manauta and Anna Salat, part of chapter 6 of the book Layers, an atlas of composite stratification.
The palatal surfaces of maxillary teeth have a close relationship with posterior disocclusion and cutting movements.
In one of the most important steps, the palatal surfaces of the affected teeth are rehabilitated successfully with composite restorations.
The recovery of the palatal anatomy and reinstatement of function through rehabilitation are of essential importance in modern restorative dentistry.
The layering technique in the palatal surfaces not only is useful for obtaining interesting color effects, but also uses small composite resin increments that will enable us to create precise structures and a beautiful anatomy.

When Little Space Is Available
The starting point is a correctly stratified dentin core.
Opalescent mass is modeled in the incisal area. It is important to respect the facial shape as well.
An orange stain is placed in the lingual fossa area in a subtle layer of about 0.2 mm.
One by one, the lingual ridges and the cingulum are modeled with a light intensive white or a bleach dentin.
Independent modelling of each structure allows greater accuracy.
Marginal ridges are constructed with the same white color (either dentin or intensive).
The marginal ridges and cingulum are covered with a subtle layer of enamel. Independent layering of each area allows formation of a crack in the cingulum.
It is also important to model the enamel by sectors. As the incisal edge is approached, it is important to model the desired shape, in this case an abrasion.
A dark brown stain is placed in the crack area. In the incisal abrasion, a hybrid composite mixed with brown stain must be placed. Stains are not ideal for large areas.
The finished tooth shows how, with little space, we can reproduce a highly characterized restoration. It is almost like a staining technique but with the added benefit of creating depth.
