Recently I raised my concern (search by 'Lava crowns by KDAH') on Practo regarding the so called Lava Premium product I was handed over by Kokilaben Dhirubhai Ambani hospital. I got few replies here but no one considering this unfair. This is surprising. Let me again bring more clarity over my case. I paid the hospital Rs. 66k for 3M Lava premium ceramic crowns (4) but I was given cheaper product of a local brand along with a warranty card which is not at all of a 3M product. Though it was labeled as "Lava Premium" by dentist and lab partner. I contacted 3M and they have confirmed that this is not a 3M case. On practo I just want to know it is what usually happens with everyone who pay for a 3M branded crowns, before complaining directly to the doctor.
