The long-term success of implants depends upon the
degree of osseointegration that can be achieved, which
is largely determined by the volume and quality of bone
available at the time of surgery. Bone height and volume is
often diminished in patients due to the extended time after
tooth loss and this is a major limitation impacting long term
dental implant treatment success. Some of the commonly
used surgical techniques for ridge augmentation are (i)
Osteoperiosteal flap (OPF); (ii) Distraction osteogenesis
(DO); (iii) Block grafting; (iv) Guided bone regeneration
(GBR) using membranes; and (v) Subperiosteal tunnelling for
minimally invasive approach to GBR. This talk discusses the
development of bioceramics graft materials with controlled
microstructure and superior biological properties to those
currently available. Dicalcium phosphate cements, brushite

and monetite, resorb faster in vivo than hydroxyapatite (HA).
Monetite (unlike brushite) does not re-precipitate as HA in vivo
and demonstrates superior osteoconductive properties. We have
produced monetite disc grafts by varying processing conditions
which alter their physical properties such as porosity, surface area
and mechanical strength. Histological observations after 12 weeks
of onlay grafting on rabbit calvaria reveal higher bone volume (38%)
in autoclaved monetite grafts in comparison with the dry heat
prepared monetite grafts (26%). The vertical bone height gained is
similar for both the types of monetite grafts (up to 3.2 mm). This
talk discusses and provides information regarding two types of
monetite onlay grafts prepared with different physical properties
that could be used for achieving more predictable vertical bone
augmentation.
