The following report analyzes the need for a device to be used in conjunction with the Bicon taper lock abutment systems used for prosthetic reconstruction when a tooth has become extensively damaged. In this system, an implant is placed in the jaw and integrated through bone regeneration. The titanium implant acts as a synthetic root, producing a solid foundation for the prosthesis. An abutment is then placed in the implant. The abutment serves as a post for cementing a prosthetic tooth to the implant. The abutment in the Bicon system is applied to the implant through a taper lock mechanism, which is of a tapered interference fit for fitting the two components together. This prevents loosening of the prosthesis over time. The effeciiveness of the taper lock is highly dependent on the accuracy of the installation force. The current method of application involves placing a handle against the abutment and tapping the handle with a dental mallet. The force used in the current method is inconsistent and often leads to insufficient installation force. To improve the success of this prosthetic fastening system, a new tool design is proposed. The proposed tool design will apply a consistent seating-force, install the abutment in one step, and properly hetion in different areas of the mouth. The tool must be compatible with all types of abutments currently produced by Bicon. The proposed tool will also be economical, ergonomical, and durable enough to withstand sterilization and repeated use.
