The recent paper by Elledge et al
1
provides an overview of the plethora of total temporomandibular joint (TMJ) replacement
systems that are currently available on the market. The paper emphasises the importance
of design factors, such as sufficient lateral fixation of the ramal component to the
mandible, and the correct use of biomaterials. The discussion focuses on potential
flaws in the biomaterials of some recent systems and mentions concern regarding the
use of a totally ultra-high-molecular-weight polyethylene fossa.

Mommaerts had the same concern,
2
which led to the use of a titanium-backed ultra-high-molecular-weight polyethylene
fossa. While the ramal portion was completely 3-dimensionally-printed in the titanium
alloy ELI 23, the articulating surface of the condyle was also coated in HadSat® using
Mommaerts’ technique, which was not mentioned in the review. Both modifications play
important roles in improving the quality of the TMJ replacement implant.To read this article in full you will need to make a payment
