Maxillofacial defects caused by cancer treatment are a huge problem,
affecting the quality of life of patients. Some of these deformities
are minimized using facial epistheses, which needs some additional
retenion devices, like glasses or skin adhesives. The use of extraoral
fixtures as bone anchorage was introduced many years ago and since then
many patients were rehabilitated with better results. Nevertheless, in
many cases due to poor bone conditions (i.e. irradiated bone) the
success rate of implants are not so good, causing difficulties to
rehabilitate the cases. One possible cause of fixture failure could be
the poor primary stability achieved in some cases, due to the small
dimensions of the fixtures causing a few bone contact with the surface
of the implant. Nowadays many researches are being done related to the
surface of the fixture, searching for a better primary stability and
for a increase of bone contact. Ordinary extraoral implants usually
possess a machined surface, until now there is no published report
about surface modifications in this kind of implant. This paper
presents a new porous surfaced Brazilian extraoral implant
(MasterExtraâ, Conexão, Sistema de Próteses, São
Paulo, Brazil) that can provide optimal facial rehabilitation due to
enhanced bone-to-implant contact and greater long-term stability. Two
case reports are described to elucidate its use
