Abstract
Objective
For alveolar bone grafting (ABG), we have been performing surgery using a technique
in which a cortical bone lining iliac endplate is applied to the anterior nasal aperture
inferior margin. Herein, we examined the postoperative bone-bridge morphology following
ABG using conventional and cortical bone lining techniques.
Study Design
Fifty-five unilateral patients who underwent ABG at our clinic from October 2012 to
March 2019 were included. We used postoperative CT data to compare the labiolingual
width of the grafted bone and anterior-posterior and vertical shapes of the nasal
aperture inferior margin with respect to the ungrafted side.
Results
The cortical bone lining technique was superior to the conventional method. Regardless
of alveolar cleft width or oral-nasal fistula, the cortical bone lining technique
showed good results. Also, tooth movement into the grafted area was involved in the
maintenance of residual graft bone; however, the cortical bone lining technique had
better results.
Conclusions
The cortical bone lining technique allows for the physical closure of nasolateral
mucosal fistulas when it is technically difficult and can apply sufficient pressure
to the bone marrow cancellous bone filling over the cortical plate bone. Our results
illustrate the effectiveness of the cortical bone lining technique.
