Osteoconduction
The graft acts
as a template or trellis
to assist in bone formation
Osteoinduction
The graft acts to
stimulate or to induce
new bone formation.
Osteogenesis
-The cells of the
graft actually produce
new bone.extracted and sterilized.
These materials have been tried and
discarded
Free Osseous Autograft
Combination of cortical and
cancellous bone; donor sites
include iliac crest, bone from
osteoplasty or ostectomy ,
healing extraction site,
maxillary tuberosity,
edentulous ridge or retromolar
area.
Contiguous Osseous
Autograft -
Compression of "green
stick" fracture of alveolar
bone into osseous defect;
seldom used.
Allograft -
Freezedried,
frozen or chemicaltreated
bone from another
individual; no need for
additional surgical
Alloplastic Graft
Synthetic substances; porous,
resorbable
B-tricalcium phosphate
(Synthograft); dense, nonresorbable
hydroxyapatite (Calcitite,
Periograft).
Composite Graft
Combination of
autogenous graft material
and allograft or alloplast
material used as an
extender
Xenograft
another species
Calf bone (Boplant) treated by
detergent extraction,
sterilization, and freezed-dried.
Kiel bone is calf or ox bone
denatured with 20% hydrogen
peroxide, dried with acetone and
sterilized with ethylene oxide
Anorganic bone
Ox bone
