“…Owing to the prosthesis design, translatory movements of the condyle are often absent or severely restricted (Mercuri and Anspach, 2003). Stock TMJ prostheses are less expensive, but it is often hard to fit a stock prosthesis into a mutilated joint area with disturbed anatomy (Driemel et al, 2009;Mercuri et al, 1995). Custom-made prostheses based on three-dimensional computerized tomography (3D-CT) solve these fitting problems, but these prostheses are more expensive and require more extensive preoperative planning than stock prostheses (Mercuri and Anspach, 2003).…”

“…Custom-made prostheses based on three-dimensional computerized tomography (3D-CT) solve these fitting problems, but these prostheses are more expensive and require more extensive preoperative planning than stock prostheses (Mercuri and Anspach, 2003). The use of adaptable materials in order to ensure a close fit of the prosthesis to the skull leads to micro-motions between the prosthesis and bone once it has been implanted in the body, causing secondary bone resorption (Mercuri et al, 1995;van Loon et al, 1995).…”

“…Implants made by ALM methods can have increased longevity by providing more secure fixation using tailored porosity, which cannot be achieved by conventional manufacturing techniques [11]. The presence of an optimised and selective porous structure can influence host bone regeneration by creating an environment which allows cell spreading, proliferation and subsequent bone formation, enabling integration of the implant into the body.…”

This paper presents an original model of powder bed generation developed within the frame of an integrated modelling approach for studying the interaction of physical mechanisms in additive layer manufacturing (ALM) of orthopaedic implants. The model is based on cellular automata (CA) approach and describes the relationship between moving particles of different sizes during deposition on a surface in three dimensions. The surface is defined by the horizontal two-dimensional CA on which particles fall and irreversibly stick to a growing deposit. The model allows for consideration of different restructuring cases when particles are allowed to rotate as often as necessary until achievement of a local minimum position. Changes in the packing density of the powder bed have been investigated numerically depending on technological parameters, such as particle size distribution, deposition rate and sequence of powder deposition. The model has been developed with the aim of merging to the finite element (FE)-based integrated model and is applicable to a different ranges of materials including metals and also non-metals.

Rapid prototyping is a relatively new technology, which although prominent in the engineering industry is only just starting to make an impact in the medical field. Its current medical uses are mainly confined to surgical planning and teaching, but the technology also has the potential to allow for patient-tailored prostheses. The work reported here describes the application of a simplified selective laser sintering apparatus with ultra high molecular weight polyethylene (UHMWPE). The morphology and chemistry of the starting powders and lased material have been characterized using Fourier Transform Infra Red spectroscopy and a combination of light and scanning electron microscopy. It was found that solid linear continuous bodies could be formed, but material shrinkage caused problems when trying to form sheet-like structures. The porosity of the formed material was also a concern. The material exposed to the laser beam was shown to have undergone degradation in terms of chain scission, cross-linking, and oxidation. It has been concluded that to apply this technology to the fabrication of UHMWPE devices requires the development of improved starting powders, in particular with increased density.
