Abstract of US2004259051

An apparatus includes a template which locates hole positions in a jawbone while the template is separated from the jawbone by gum tissue. The template follows a contour of the gum tissue surrounding the jawbone and has guide holes which receive a cutting tool. Anchoring elements attach the template to the jawbone. A system includes means for scanning an implantation site on a patient's jawbone, simulating the implantation site, and determining nerve-rich areas or nerve paths in the jawbone. A holed template is produced which is separated from the jawbone by at least gum tissue of the patient. Attachment hole positions in the jawbone are located so as to avoid nerve paths. A method of forming holes to attach a dental implant to a patient's jaw bone without surgical intervention in gum tissue of the patient to expose the jawbone is disclosed which avoids impingement on a nerve path.
