Dental CT Scans Explained Why Cone Beam CT Scans are the Bentley of Dental Imaging Cone   beam   images   not   only   provide   undistorted   and   accurate   views   of   the   jaws,   but   it allows   for   different   views   such   as   cross-sectional,   axial,   coronal,   sagittal   and   additional areas.        It    allows    for    accurate    measurements    to    be    taken    and    will    determine    the patient’s bone density. What are Dental CT Scans Dental    CT    Scans    are    three-dimensional,    high-resolution    imaging    that    has    become    a necessity   and   reality   in   dentistry.   With   the   advent   of   Cone   Beam   Computed   Tomography (CBCT),   implants   can   be   placed   with   unparalleled   accuracy.      Third   molar   surgery   can   be planned   with   precise   knowledge   of   mandibular   nerve   location,   and   accurate   diagnosis and   treatment   planning   can   now   be   accomplished   at   one   time   and   in   one   location. Cone    beam    CT    imaging    has    become    the    standard    of    care    in    oral    surgical procedures, orthodontics, in implant dentistry and cosmetic facial surgery. What is Cone Beam Computed Tomography (CBCT)? For   many   years   dental   professionals   have   relied   on   intraoral   radiography,   panoramic   radiography,   and   conventional tomography    for    diagnosis    and    treatment    planning.    These    commonly    used    imaging    modalities    produce    only    two- dimensional   and/or   distorted   images   with   superimposition   of   structures   outside   the   area   of   interest.   There   has   always been   a   need   for   three-dimensional   (3-D)   imaging,   but   the   technology   has   only   recently   become   readily   available.   Cone Beam   Computed   Tomography   (CBCT)   uses   a   cone-shaped   beam   and   digital   processing   to   reconstruct   a   virtually   distortion- free   3-D   image   using   a   single   rotation   in   a   sitting/standing   position,   similar   to   that   of   a   panoramic   radiograph.   CBCT scanners   are   compact   in   size,   capable   of   producing   high-resolution   3-D   imaging   of   hard   tissues,   and   are   compatible   with computer-aided imaging software for improved diagnosis and treatment planning. Clinical applications of CBCT imaging Implants - Implant planning and site development. Extractions — helps determine location of nerves, sinus, and roots. Orthodontia — jaw symmetry, configuration of roots, impacted canines. Maxillofacial — orthognathic surgery, fractures, jaw pathology. Periodontics — sinus augmentation, advanced grafting procedures, periodontal defects. Endodontics — canal measurements, additional canals, configuration of root canals. TMJ/TMD — detection of bony defects, asymmetry, spurs, condylar changes. ENT specialists — sinus and airway studies. Benefits of CBCT imaging Imaging exposes patients to less radiation than traditional CT scans. The scan is fast and comfortable to the patient. Reduction in metal artifacts. One scan produces a volume of images that can be viewed and manipulated. Clinicians can illustrate recommended treatment plans to patients using 3-D software. No superimposition and minimal distortion. Allows clinician to visualize internal anatomy that cannot be diagnosed externally. Lower cost for patient when compared to traditional CT. Enhanced communication with patients and colleagues.
