There are systems that make crowns from pre-graduated blocks of zirconia but even with a hand painted finish on top they cannot match the luminosity and realism of porcelain fused to zirconia….

In tests conducted by the makers of Branemark implants recently they found that there was considerably less build up of plaque on Zirconia than on titanium, the biocompatible material used for implants, and even more so than on actual teeth….

With zirconia based crowns there is no discolouration and because of the computer aided manufacturing process the crown fits the tooth perfectly meaning no bacteria can get underneath so undermining the supporting tooth….

A dental implant is essentially a substitute for a natural root and commonly it is screw or cylinder shaped. Each implant is placed into a socket carefully drilled at the precise location of the intended tooth. If an implant has a screw-thread on its outer surface it can be screwed into position and if it does not, it is usually tapped into place. The main aim during installation of any implant is to achieve immediate close contact with the surrounding bone. This creates an initial stability, which over time is steadily enhanced by further growth of bone into microscopic roughnesses on the implant surface….

Dental implants are routinely placed beside natural teeth and this is generally very safe to do. The only exception to this would be if the natural root was very curved or tilted unfavourably in the proposed path of the implant. This could cause the root to be damaged by the implant, however this can usually be avoided by careful pre-operative planning….

If you have good general health then dental implants will almost certainly work for you. However, habits such as heavy drinking or smoking can increase the number of problems associated with initial healing and thereafter may negatively influence the long-term health of gum and bone surrounding each implant. Remaining teeth might also be compromised making treatment planning less certain.

If you are aware of bad breath, loose teeth, or have noticed excessive bleeding, particularly when your teeth are cleaned professionally, you may have gum problems. Periodontal (gum) disease is a major cause of bone loss and with reduced bone, dental implant treatment can be more complicated.
