I have to get a dental implant in a front tooth and never had one before. I know it will be very costly, but there seems to be different materials( from porcelain to titanium) and techniques vary. The post and crown are 33 years old and due to bone absorption the post is failing. No infection or abscess. Any recommendations as to type, technique, pre op and post op issues? Any advice is really helpful as I have never had one before. Thank you.
