Splint manufacturing method for use during operative correction of dysgnathia, involves subtracting spatial representations of upper and lower jaws by virtual sleeve of splint mathematically, and manufacturing splint by rapid prototyping

摘要

The method involves subtracting spatial representations of an upper jaw and a lower jaw by a virtual sleeve of a splint mathematically, where the splint contains exact bite impressions of the lower jaw and the upper jaw in optimal occlusion. The virtual sleeve of the splint is placed between the lower jaw and the upper jaw. The splint is manufactured by a suitable process i.e. rapid prototyping, and is utilized in real operations.
