While immediate implant placement has become a routine clinical strategy to preserve peri-implant architecture, success heavily relies on having sufficient apical and palatal bone volume for primary stability—an anatomical baseline often compromised by dentoalveolar compensations.
In the retrospective CBCT study titled "Comparison of alveolar bone width and sagittal tooth angulation of maxillary central incisors in Class I and Class III canine relationships" (published in BMC Oral Health), Lei et al. evaluate how sagittal canine discrepancies directly influence the anterior bone plate.
Analyzing 107 patient scans, the authors revealed that individuals with a Class III canine relationship exhibit significantly greater labial inclination of maxillary central incisors, alongside a notably thinner palatal bone plate at the apex compared to Class I controls.
These findings carry critical implications for surgical and orthodontic planning, emphasizing the elevated risk of apical palatal perforation during immediate osteotomy when managing previously proclined anterior teeth.
