Are Procera Veneers Better Than Traditional Empress Veneers?

The question is what is "better"?  Are we talking about strength?  Aesthetics?  Feel?
There will be MANY opinions on this.
Veneers depend on the ability to bond, and many stronger materials today cannot bond to dentin or enamel and must be cemented.  Cemented veneers do not "stick" to teeth as well as bonded, and Empress® bonds VERY well.
The determination of quality is equally factored by the lab technician, not just the dentist that is creating the preparations.  A skilled technician can cut back the Empress to add shades of porcelain to make a true work of art with extreme strength.  My opinion is that the Procera is not quite there aesthetically.  Yet.
For me, in my office, I would choose Empress or other Ivoclar products, like eMax.  Strength and beauty and the ability to bond.

Procera™ porcelain is a very strong porcelain and can be employed to make very attractive crowns.  This porcelain type does not bond well to teeth and requires a heavier preparation to achieve long term retentiveness.  It is not a commonly used porcelain choice for veneers.

Empress™ porcelain is an incredibly attractive porcelain used for veneers.  It not only bonds extremely well to enamel and dentin, it has optical properties that are very attractive.  This porcelain is very translucent and appears lifelike. The positive characteristic of translucency does exclude its use when the clinical agenda is to cover dark teeth.  The darkness will very often show through.  Empress as a veneer material choice still has a significant market share and was once the "go-to" choice for veneers but today E Max porcelain is more popular due to it's equally impressive optical characteristics and a superior strength.

I do not think one veneer is better here than the other. You are also correct regarding how important the skill of the dentist plays into how your veneer will look. Also you must remember the dental lab the dentist uses and the skill of the technician needs to be considered as well. You signed your question, 'in India,' so i assume you are looking for dental work there rather than the US.
India is a leading country at the moment, in dental tourism. The standard of care is very high and technology, care and cosmetic dentistry is very competive with the US. Below are some useful dental websites in India you might want to explore and will help you in your decision: www.chandigarhdentist.com and www.cosmeticdentistindia.com.
Hope this helps. Also explore the Apollo Hospitals in Chennai and New Delhi. They are state of the art and do dentistry as well as general medical procedures. Prices are much cheaper in India. Just do your research on the computer and email the dentists. Good luck!
