CBCT assessment of alveolar bone wall morphology and its correlation with tooth angulation in the anterior mandible: a new classification for immediate implant placement.

Mandibular anterior teeth have predominantly thin facial and lingual crests, making the lingual bone apical thickness crucial for IIP. Although anchorage can be obtained from lingual bone, tooth angulation and tooth types had an impact on IIP planning. Hence, the new classification based on TA and alveolar bone wall may enable rational clinical planning for IIP treatment.
