This paper discusses the use of LM and CAD in bone implants. It highlights a number of researches describing the implementation of LM and CAD processes in medical applications. It further describes the design process for customised medical implants by layered manufacturing. The paper then examines the feasibility of designing of new implants for mandibular applications based on bioceramics and new fixation methods. The main drawback in many implants is the difficulty in achieving a tightly secured and comfortably fitted implant between the surrounding bone tissues of individual hosts. This paper suggests an LM and CAD system approach that has a possibility to overcome this. Mandibular bone implants were chosen for initial investigation. This paper also investigates the use of bioceramics as the possible material for the implants because of its minimal reaction to host tissues and varying porosity, which can be adapted to suit the interfacial surfaces of the implants. The paper then concludes by describing initial studies on the proposed processing route and outlining future work.
