Assessing the Interdental Septal Thickness in Alveolar Bone Grafting Using Cone Beam Computed Tomography.

Abstract

OBJECTIVE:

To assess the interdental septal thickness of grafted bone bridges using cone beam computed tomography (CBCT).

PATIENTS:

Of 71 patients with cleft lip and/or palate having undergone alveolar bone grafting for the first time at least 6 months previously, 52 patients with 57 grafted sites rated type I or II based on the Bergland scale using occlusal radiographs were selected.

INTERVENTIONS:

CBCT was performed for each bone-grafted alveolar cleft within 1 week after the occlusal radiographs were taken.

MAIN OUTCOME MEASURES:

The thickness of the grafted bone bridge was evaluated using CBCT according to the relationship between crest thickness and the root width of cleft-adjacent teeth, and the results were classified into four categories, with scores of 1 to 4 indicating that the thickness of the bony bridge was ≥100%, ≥75%, ≥50%, and <50% of the root width of the cleft-adjacent teeth, respectively.

RESULTS:

Of the 34 grafted sites rated type I on the Bergland scale, 15 (44.12%), 10 (29.41%), 4 (11.76%), and 5 (14.71%) clefts were scored 1 to 4 on interdental septal thickness using CBCT, respectively. Of the 23 cases of type II, 3 (13.04%), 9 (39.13%), 1 (3.45%), and 10 (43.48%) clefts were scored 1 to 4, respectively.

CONCLUSIONS:

The interdental septal thickness of grafted bone bridges with clinically successful heights based on the Bergland scale (type I or II) using occlusal radiographs varied significantly in the evaluation using CBCT.
