The presence of which root anatomy can complicate implant placement?

Curved roots present specific challenges during implant placement due to their non-linear shape, which can interfere with the ability to place an implant in a straight trajectory. The curvature of the roots often leads to variations in the available bone density and volume around the root, which may also complicate the assessment of bone quality when planning for an implant.

Additionally, curved roots can create difficulties in achieving an adequate amount of primary stability for the implant since a straight implant might not align properly with the surrounding bone. This alignment issue could necessitate modifications in the surgical approach, including careful angulation, potentially increasing the complexity of the procedure.

In contrast, single conical and cylindrical roots generally offer a more straightforward anatomy for implant placement, while divergent roots can also be managed effectively with proper planning and angulation. The presence of curved roots is notably more likely to necessitate advanced techniques or additional considerations during the implant placement process.
