Hi Dr, I am 62 years old and to be blunt my upper teeth have seen better days! I have receding gums and now since having researched on the internet about the ‘all on 4’ dental implants I am now becoming a bit confused as to which is the better option for me, ‘all on 4’, or the 6 implants treatment option that I have seen. This is because some say that 6 implants will support the arch better and last longer. Also I understand that the 6 implants comes with a ceramic arch with zirconia better than acrylic or do you know of any better materials in use currently for constructing the arch. If it is any help to your accuracy in answering my questions I would like to make it clear that I am looking for something that will last for a very long time and look very good.
