The aim of this pilot study was to evaluate the
success rate of a chairside ridge augmentation procedure using bone autografts
harvested with trephine drills and placed without the use of screws.
Thirty patients were recruited for the study. After the
surgical site was anesthetized and a crestal incision was made, an envelope flap
was retracted using blunt dissection limited to the graft site, and the
periosteum was raised intact and undamaged from the bone. The flap was extended
laterally to obtain sufficient space for the bone graft. At the donor site, bone
was obtained from the external oblique ridge area. A #5 or #6 trephine drill was
used to harvest one or two pieces of bone. The bone blocks were placed inside
the envelope flap at the recipient site, which was then sutured and covered with
periodontal dressing. Antibiotics, analgesics, and mouthwash were prescribed.
Measurements of ridge width were performed using CBCT before and 3 months after
surgery. The pre- and post operative results were compared using paired t test.
Pre- and post-operative mean ridge widths were 2.23 ±
0.79 and 5.16 ± 0.68 mm, respectively. The mean increase in width was 2.92 ±
0.89 mm(P < 0.001).
This non-invasive and
simple technique provided an acceptable increase in ridge width. As the sample
was small, we recommend further clinical investigation with larger samples to
confirm that this technique may be used successfully as an alternative to
current invasive augmentation methods.
