Purpose: Little research has been done to determine the amount of bone harv
ested from implant site preparations using an inline bone collector. This s
tudy looked at the amount of bone that can be harvested from common dental
implant osteotomies.
Patients and Methods: A total of 24 implants were placed in 9 patients over
a 3-month period. Implant size ranged from 3.75 X 13 mm to 4.75 X 13 mm. N
ine implants were placed in the maxilla, and 15 implants were placed in the
mandible. Seven patients were female, and 2 patients were male. The patien
t age ranged from 27 to 72 years. Four patients had implants placed within
5 years after tooth extraction, and 5 patients had implants placed 5 years
after tooth extraction: an analysis of variance was used to determine if th
ere were statistical differences between maxilla versus mandible, male vers
us female, and edentulism less than or greater than 5 years.
Results: The average bone volume from the 24 osteotomies was 0.195 +/- 0.09
9 mL. The average osteotomy site measured 4.02 X 12.90 min. There were no s
tatistical differences noted among maxilla and mandible, gender, or time of
edentulism.
Conclusions: When using an inline bone collector to harvest implant osteoto
my sites, an average of 0.195 nil, of bone can be obtained from a site appr
oximately 4.0 X 13 mm. This bone can often be combined with a xenograft or
alloplastic material to provide extra bulk to fill peri-implant defects. Wh
en multiple implant sites are prepared, often sufficient bone can be obtain
ed with the bone collector alone. (C) 2001 American Association of Oral and
