Category 74 Australasian Dentist CASE STUDY: 65-year-old female for implant planning Clinical notes: Implants. Impression on quadrants 1 and 4. The Radiologist produced the following report upon review of the DMDI imaging: FINDINGS: In quadrant 1, 14-16 are extracted. At the site of 16, the alveolar process measures 8.8 mm wide and 3.9 mm tall. (Fig 1) Fig 1a: Axial view of quadrant 1 Fig 1b: The alveolar process of the 16 tooth created from CBCT scan 17 is root filled and is crown restored with mild extrusion of the filling material through the apical foramina with 2-3 mm periapical lucencies with sclerotic margins which are of doubtful clinical concern. (Fig 2) Fig 2a: Sagittal view of the 17 Fig 2b: Axial view of the17 tooth tooth showing lucencies. displaying periapical lucencies around both palatal and buccal root. The roots do not protrude through the floor of the maxillary sinus. The periapical lucency is more prominent around the DB root. (Fig 3) Fig 3: Sagittal view of distal buccal root of the 17 tooth 24 is root filled and is crown restored with a post-core crown in situ. Severe bony recession with no periodontal ligamentous space. (Fig 4) Fig 4a: Coronal view of the 24 tooth Fig 4b: Sagittal view of palatal root Fig 4c: Sagittal view of buccal root In quadrant 4, 47 and 48 are extracted. The sockets are ossified. The alveolar process measures 6.5 mm wide and 14 mm craniocaudally from the alveolar ridge to the inferior alveolar nerve canal. (Fig 5) Fig 5a: Axial view of quadrant 4 tooth Fig 5b: Alveolar bone of the 47 CONCLUSION: No aggressive bony lesion seen. Maxillary sinuses are clear. Both acute and chronic bony pathology is important to accurately define and diagnose. While much information can be ascertained clinically or with 2D imaging, Cone Beam CT offers unique detail and is now a key component of diagnosis and treatment planning. This provides both confidence and diagnostic completeness to the clinician and patient. The clarity and precision of high resolution CBCT is invaluable clinically in such cases, as well as other dental and maxillofacial treatment situations. DMDI provides unique, high quality dedicated CBCT scans and reconstructions with prompt imaging and report turnarounds to enhance treatment planning and help deliver optimal patient outcomes.
