Modern technology finds applications in all areas. The computer aided design (CAD) and 3D Printing, which has become prevalent over the last generation, is used to produce replacement teeth that are superior to earlier substitute teeth.
Implants secured with titanium posts were first used in the 1960s. These proved superior to earlier replacement teeth because the titanium post would bond to the jawbone. Other materials would be rejected by the body. It was found that a titanium post implant with a porcelain tooth would last for several decades under normal conditions.
Of course everybody’s mouth has a different shape. So it can be tricky to make a replacement tooth that fits neatly in with the surrounding teeth. This is where computer aided design becomes useful.
Replacement teeth were always made to fit the individual’s mouth. For many years molds were made of the patients teeth, and any replacement teeth were made according to this. The patients bite (how the top and bottom teeth fitted together) was also a factor here. But this older method has been largely superseded by computer technology. It is now fairly easy to make a complete computer model of an individuals mouth, including the movement of their jaw, and to make custom designed implants to fit this individual. This is far more accurate than a physical mold.
3D printing means that a replacement implanted tooth can be manufactured to very exactly fit the surrounding teeth. This is far better than merely shaping a generic implant. Use of CAD and computer manufacturing for 3D printing of teeth makes the production of a replacement tooth very streamline.
The visible part of the implant, the part hat looks like a natural tooth, can be made of ziriconia or lithium disilicate. These are both strong and can be manufactured with 3D printing. This makes then superior to the older porcelain implants which could not be 3D printed, and which were not quite as strong.

Replacement teeth are not just about aesthetics. Of course they are needed for the mouth the function properly; they allow us to chew food and speak clearly, as if we still had our natural teeth. But implants are also important for maintaining the long term health of the mouth. If there is a gap left by a missing tooth then the surrounding teeth tend to shift, causing alignment problems. This can also lead to jaw alignment problems. Implants help keep the other teeth neatly in place.
