ABSTRACT
Aim: The bone particles harvested during osteotomy could be used as autogenous bone graft materials to
correct a bony defect prior to implant placement. Methods: A simple surgical procedure was described
in which autogenous bone was harvested from the drills during the preparation of implant sites. Eleven
samples were obtained from bone drilling during fi xture installation in 11 patients (5 men and 6 women)
with an average age of 57 years. These samples were subjected to histological preparation, in order to
evaluate for the presence of viable osteoblasts. Results: Histological evaluation of the samples suggested
that the viability of the bone tissue was maintained. Conclusion: The results show that this method of
harvesting autogenous bone may be useful in situations where small amounts of bone are required.

INTRODUCTION osteoblasts in bone tissue harvested with drills during
implant site preparation.
In our clinical practice, a bone graft is often necessary
to correct a bony defect prior to implant placement. METHODS
Autologous bone is considered to be the “gold standard”
for bone grafting, [1-3] as it does not produce adverse Clinical procedure and patient selection
reactions and has optimal biocompatible remodeling A total of 11 patients (5 men and 6 women, aged between
patterns and osteoinductive capabilities. [4-6] Grafting 35 and 75 years, with an average age of 57 years), in
particulate bone is considered to be a better option than good general health condition, were included in this
en bloc harvesting due to the former’s capacity to adapt study. Patient selection criteria for this study were
to the site of engraftment; it enables a larger quantity of established so as to include patients with loss of one
harvested material to be grafted, with advantages in terms or more dental elements and with moderate alveolar
of long-term cell survival, although the latter is influenced atrophy diagnosed in preoperative X-ray examinations,
both by the harvesting technique and the dimensions of including panoramic radiography. An Ethical Committee

patients gave their informed consent to participate in
The aim of this study was to assess the presence of viable
