While performing implant surgery during the drilling procedure, the clinician must:

The correct choice encompasses all critical aspects that a clinician must consider during the drilling procedure in implant surgery.

Determining the direction of drilling is vital for precise placement of the implant, ensuring that it is aligned properly with the intended path. Proper angulation minimizes the risk of complications and enhances the functional and aesthetic outcomes of the implant.

Being aware of bone density in the surgical area is crucial as it influences the drilling technique and the amount of torque that can be applied. Different bone densities require adjustments in drilling speed and pattern to avoid overheating the bone, which can compromise bone viability.

Maintaining at least 0.5mm to 1.0mm of bone on the buccal and lingual aspects is essential for ensuring adequate support and stability for the implant. Insufficient bone can lead to implant failure due to lack of integration or could result in adverse aesthetic outcomes.

By acknowledging all these factors, the clinician increases the likelihood of successful implant placement and long-term integration, which is why the comprehensive understanding represented by the all-encompassing answer is crucial in implant surgery.
