UPDATE: Leaving this here for posterity.

I misunderstood regarding the crowning material.

To simplify things, there are basically 2 materials commonly in use at the moment; one being Porcelain Fused Over Metal (PFM) or the higher end, Zirconia. The price difference between the 2 is 1x of each other (ie: PFM is at RM1,000.00 per tooth and the Zirconia is somewhere at RM2,000.00 per tooth).

PFM is basically metal base with porcelain exterior hence the name but now, it can be had with Zirconia on its exterior with no extra charge. There are pros and cons for both the PFM and the Zirconia but the biggest consideration is that if you have or suspect or fear that you may have an allergy to metals then PFM is to be avoided.
