Researchers at the University of Ankara, Turkey have designed an innovative CAD based implant guide. The design features a plastic stent produced by rapid prototyping methods that snugly fits the implant handpiece and uses a square slot system to guide the drill direction as opposed to the metal/plastic sleeves used by similar systems. This allows for better visualization of the surgical area and negates the use of stepped sleeves of increasing diameter to guide the twist drill. Additionally it eliminates the risk of metal shavings entering the osteotomy site.
