ORAL AND MAXILLOFACIAL SURGERY
The success of a surgical procedure largely depends on an accurate and precise diagnosis. Preoperative radiological diagnostics gives the surgeon a visual overview before and during the surgical procedure.
Pathological conditions and anomalies can be simply diagnosed and assessed with the help of 3D images. An unlimited number of images can be made from a single scan with a low level of radiation, making the Cone Beam CT the best device for maxillofacial surgeons.
The 3D CT offers the best diagnostic possibilities in surgical procedure planning for a vast array of surgical procedures:
EXTRACTIONS – root anatomy and position, retained roots
ALVEOTOMY – inclination, position, relation to bone and surrounding structures, phase of root development
CYSTS AND TUMORS – shape, size, spatial distribution, relation to other anatomical structures
VESTIBULOPLASTY – ridge thickness, ossification, ridge undulation
ORTHOGNATHIC SURGERY – excellent visualization and possibility of better communication between specialists, symmetry and asymmetry
RECONSTRUCTIVE SURGERY – clear view of anatomical structures, easier procedure planning, determining the middle
APICOECTOMY – periapical process, overfilling, bone defect, section behind root
Foreign bodies, like roots, implants, instruments and impression or augmentation material, introduced by trauma or iatrogenic causes can be easily and precisely located. It can be determined whether the foreign bodies are located in the sinus cavity or submucously, and if any inflammation or chronic changes exist around them.
Scanora 3D makes clear and detailed transversal, axial and sagittal images of the joint. They largely help determine intra-articular pathology and help to plan the surgical procedure on the joint. It is possible to determine the presence of degenerative processes, condylar dysplasia, joint space narrowing, eroded surfaces, subchondral sclerosis, osteophytes, cysts, trauma and primary or secondary tumors.
A large number of sections and angles of the impacted tooth can be made for the purpose of an alveotomy. These images are of great help in determining the relation of molars with the bottom of the maxillary sinus or mandibular canal, the impacted cuspid with the roots of adjoining teeth and the base of the nasal cavity, mesiodens with the incisive canal, etc. It is possible to determine the presence of adjoining tooth resorption and a small-scale preparation of soft tissue can be planned. As this information is present, the specialist knows what to expect before starting the alveotomy, which reduces the possibility of potential problems to a minimum.
SYNDROMES AND MALFORMATIONS/CRANIOFACIAL DYSPLASIA
3D diagnostics gives an insight into the individual specifics and morphological characteristics of the patient. Planning and performing surgical treatment is simplified.
CLEFT LIP AND/OR PALATE
The shape and relations of unfused structures, premaxillas, the position and relation of impacted and erupted teeth, position in the ridge, relations of antagonized ridges, maxilla and mandible morphology, occlusion and the transversal relation of dental arches can all be clearly seen. Symmetry or the rate of asymmetry of the septum, dental arches and palate can be determined. CBCT enables a clear 3D anatomical image, the assessment of cleft type and size and an assessment of residual defects after osteoplasty. Determining the clinical status has become simpler, and therapy planning more efficient.
Precise diagnostics of the root-sinus relation prevents the formation of an oroantral communication, while determining its position, size and shape facilitates therapy. Diagnostics of the root-sinus relation enables prevention, and determining the position, size and shape facilitates therapy.
Symmetry, shape, distribution and relation to adjoining structures are easily determined with 3D diagnostics. The presence of inflammations, foreign bodies, cysts or tumors can be better diagnosed. Planning operative procedures is faster and simpler. It is simpler to identify the positions of retained roots, the need for maxillary sinus floor augmentation and membranes, while sinus lifting can be more easily planned.
TRAUMA AND FRACTURES
Trauma of the maxillofacial region usually contains combined injuries of different structures. By using 3D diagnostics, it is possible to obtain a large quantity of important information during the primary phase of trauma diagnostics, since the image can encapsulate the entire region. With all potential or determined viscerocranium fractures, it is necessary to complement 2D diagnostics with a 3D CT.
