Veneers are not one material. Feldspathic porcelain, lithium disilicate and composite each behave differently in the mouth and on the model. The difference that matters in the laboratory is how light, thickness and preparation relate.
What feldspathic veneers are
Feldspathic veneers are thin ceramic shells in feldspathic porcelain. At Cosmodent they are digital: cut from a layered block, then handcrafted for the highest aesthetic outcome. The block already carries translucency and depth. The technician finishes the surface so it takes light the way a tooth does.
The work is slow on purpose. Colour is not painted on at the end. It sits in the ceramic so the veneer can stay thin and still look alive.
Compared with other veneers
Composite is faster and more reversible. It does not match feldspathic porcelain for enamel-like translucency.
Lithium disilicate is stronger and slightly more opaque. It is often the better choice when load is high or the preparation cannot stay ultra-thin. Feldspathic porcelain is chosen when the case can carry a conservative prep and the aesthetic target is enamel, not a brighter block.
Feldspathic veneers are not fragile ornaments. They hold in ordinary function when the plan, the bond and the occlusion are honest. Patients who load the anterior heavily may still be better served by lithium disilicate. That is a clinical decision, not a laboratory slogan.
What they do well
They can be colour-matched in fine steps and kept thin, so more tooth structure stays. The bond line can disappear. Light moves through the ceramic the way it moves through enamel, which is why they are used when the smile is judged at conversational distance, not only in a photograph.
Limits
They ask more of the technician and of the clinician at cementation. A rushed finish or a rushed bond shows. They are less forgiving than lithium disilicate under extreme force. Diet, parafunction and the opposing dentition belong in the indication, not as an afterthought.
Who they suit
Patients who want a natural result and a conservative preparation, without a heavy bite problem that would overrule the material. The laboratory can make the ceramic. The clinician decides whether this is the right veneer for that mouth.
