Objective To assess bone thickness augmentation and
implant survival in ridges with horizontal atrophy managed
through split crest technique with concomitant installation
of dental implants.
Materials and Methods Thirteen patients with maxillary
bone atrophy underwent surgery and had their bone
thickness assessed through cone beam computed tomog-
raphy 6 months pre- and postoperatively. Comparative
measurements of initial and final bone height and thickness
were taken using Dolphin Imaging Ò 11.5 software. The
distance between the nasal fossa floor or the maxillary
sinus and the alveolar crest determined the bone height,
while the measurement of bone thickness took into account

the distance between the vestibular cortical bone and the
palatal cortical bone at the crest level, and at 5 mm and
10 mm from it.
Results The bone height loss of 0.68 mm was statistically
significant (p = 0.01). The average horizontal bone gain
was 3.45 mm at ridge level, 3.03 mm at 5 mm from it and
2.42 mm at 10 mm from it. The mean horizontal gain for
the three regions was 2.97 mm, and the values were sta-
tistically significant for all three regions assessed
(p \ 0.01). No complications were associated with the
surgical procedures, and 23 implants were installed fol-
lowing the surgical expansion. No implants were lost
(100% survival).
Conclusion The split crest technique proved to be viable
and predictable, enabling a significant increase in ridge
thickness and a high percentage of implant survival.
