Assessment for the placement of dental implant is done by-

For preoperative assessment and planning of dental implant placement, СВСТ is the best answer among the given options.

Why CBCT? Implant planning requires accurate three-dimensional assessment of the proposed implant site. CBCT provides information about :

• Alveolar bone height and width
• Three-dimensional morphology of the ridge
• Relationship to the inferior alveolar canal/mental foramen
• Position and morphology of the maxillary sinus and nasal floor
• Presence of anatomical variations and pathology
• Selection of appropriate implant position, length, diameter and angulation

Compared with conventional medical CT, CВСТ is specifically well suited to dentomaxillofacial imaging, generally providing high spatial resolution of osseous structures with lower radiation exposure than conventional multidetector CT protocols used for comparable dental applications.
