Dr. Mohsen Ahmadi, faculty member of Shahid Beheshti University, department of Biomedical Engineering and Medical Physics, has developed a system which can determine an internal structure of a bone along a drilling path.

According to an ISCA report, Dr. Mohsen Ahmadi, in cooperation with other researchers, could develop a device which can determine internal structures of a bone during surgery, particularly to a method and device for determining internal structures of a bone during implant surgery, and more specifically relates to a method and device for determining internal structures of a bone using changes in a liquid jet flow pressure.

Based on the patent description, natural teeth may be lost as a result of dental diseases or trauma making it desirable for replacement with a dental implant. A dental implant may be surgically positioned within the mandibular or maxillary alveolar bone. A screw hole may be drilled in the mandibular or maxillary alveolar bone for fixing the dental implant in the bone.

When drilling through the mandibular or maxillary alveolar bone, the oral surgeon has to decide on a drilling axis for the implant, while being aware to avoid contact between the drill burr and the adjacent soft tissue. Generally, the decision may be made based on the surgeon's knowledge of the jawbone structure into which the implant is to be inserted, the position of the nerve tissues within the jawbone structure, and the surface area of the gum on which the dental implant must be placed.

The present disclosure described a method for determining an internal structure of a bone along a drilling path. In an implementation, one exemplary method can include drilling a bone with a hollow drill burr having a distal end and a channel including an outlet at the distal end and, while drilling the bone, receiving at the hollow drill burr a liquid at a first pressure, and passing the fluid through the channel to exit from the outlet as a liquid jet directed at the bone; sensing a pressure in the liquid jet; detecting, based on the sensing, a pressure change in the liquid jet from the first pressure to a second pressure; and upon detecting the pressure change, generating a user-detectable information indicative of the pressure change.
