Work quality and dental equipment is good. Office is nice. Attitude is passable-- BUT might become nasty and childish if you cancel your implant due to illness. On that note - Unnecessary judgmental comments from Dr Zona himself turned me away from his practice. FYI: My doctor agreed that it was wise to postpone the implant. So - Dr Zona is great as long as he THINKS that your patient conduct is "acceptable" YES -you'll get a good implant, and a smile ---BUT---- if you cancel - you might just encounter "Dr Disgruntled"
