[The retromolar area, an alternative for the mandibular symphisis graft in implant surgery: quantitative and qualitative analysis of 52 samples].
BACKGROUND
We conducted an comparative anatomy study of two sites for harvesting bone grafts for implant surgery: the mandibular symphysis and the ramus area.


METHODS
Fifty-two anatomical specimens were studied (34 from the retormolar region and 18 from the symphysis region. Measurement were: size, weight, bone volume, bone density, cortical/cancellous ratio.


RESULTS
Samples from the two sites gave equivalent results.


CONCLUSIONS
We describe the harvesting method and the difficulties encountered at each site. The retromolar site appears to be an attractive alternative to the symphysis region for bone graft harvesting.
