Introduction. The aim of this study was to assess the buccal
bone thickness in anterior maxillary and mandibular teeth and
to provide information important during immediate implant
placement. Material and Methods. The study included 245
cone-beam computed tomography scans. The buccal bone thickness was measured in the sagittal plane of the maxillary and
mandibular anterior teeth at five points (M1 – M5) (2 mm apart),
starting 2 mm from the cementoenamel junction in the coronal
to apical position along the roots. Results. The lowest mean
buccal bone thickness was observed at M1 point in all teeth in
both jaws while the highest mean buccal bone thickness was
observed at M4 (maxilla) and M5 (mandible). An increase of
the buccal bone thickness was established at every subsequent
measurement point perpendicular to the long axis of the tooth
(p < 0.001). The buccal bone thickness was less than 1 mm in
more than 60% of all teeth in the maxilla and mandible at all
measurement points. A statistically significant difference in the
thickness of the buccal bone in relation to the patients’ age was
found at all measurement points, except at M4 point of the anterior teeth of the maxilla (p = 0.456) and mandible (p = 0.109).
Conclusion. The buccal bone thickness in anterior maxillary
and mandibular teeth is less than 1 mm in more than 60% at all
measurement points. The buccal bone thickness tends to increase from a coronal to apical position along the roots.
