Hello, Implant and Crown Cost can vary according  to the City , cheaper in Tier 2, Tier 3 cities. In Delhi NCR it varies from 15K to 60K ( Implant plus ceramic crown) Also instead of best quality implant you should look for what's best in your clinical condition. Depending on your clinical scenario, age, medical issues, gum issues, oral hygiene, location of tooth in mouth , habit of tobacco use, presence of any infected tooth remnant at the site of implant what works best for an individual varies. So if one manufacturer works in someone , may not work for you. Also regarding crown Zirconia - CAD CAM crown (natural looking) in preferred/ best in front tooth , if it's back tooth and you can maintain a PFM ( Porcelain Fused to metal ) may also work. Additional procedures like bone  grafting, bone expansion , immediate implant ( implant  placement at the same time of natural tooth removal) if needed  may require  you to empty your pockets further.
