Introducing Dental 3D Imaging
Transcript of Introducing Dental 3D Imaging
What is CBCT?
CBCT is a CT scanner specialized for the oral-maxillofacial area
Surgical Treatment Planning
CT quality at a lower dose
Less exposure time approx 10-70 sec
Dose comparable to 3-4 FMX
Ability to Specify Exact Locations
Reduced image artifacts
Optimized risk assessment
Costly - $150,000 -$300,000
Not easily Reproduced
What is a Dental Implant?
Who are good recipients for implants?
Individuals to have lost one or more teeth due to periodontal disease or suffered from trauma
Applications of (CBCT) in Oral-Maxillofacial Surgery
Improves the surgical treatment planning involved in dentoalveolar procedures dealing with cysts, tumors, trauma, sinus disorders, TMJ procedures, extractions, periodontic, orthognathic, & endodontic treatment. CBCT is also used to individualize sleep apnea and cleft lip/palate reconstruction surgical procedures.
1:1 object to source ratio
Exact location & extent
Distances between structures
Compared to the traditional 2 dimensional panoramic film, the use of the CBCT in extraction treatment planning optimizes the risk assessment of inferior alveolar nerve damage due to 3rd molar extraction. This is because of the exactness of nerve location on the 3d radiographs.
Advantages in 3D Implant
History of Dental Implantation
Ability to measure bone height and width to support implant
Allows placement of the implant in the most ideal location
Avoid complications surgically
Cleft Palate TX Planning
CBCT is useful for preoperative assessment and treatment planning of cleft palate patients.
Also useful for determining post operative bone density.
For successful outcome of treatment, one needs a proper diagnosis and treatment plan.
3-D imaging helps discover a variety of Orthodontic issues BEFORE entering treatment such as:
Exact condylar positions
Corticol plate distances
Why should you Consider 3-D Imaging for Orthodontics?
Excavated Mayan burial sites in Central America showed tooth shaped shells placed in empty tooth sockets
1952 Swedish Surgeon P.I. Branemark discovered that titanium naturally fuses with bone
69% of adults ages 35 to 44 have lost at least one permanent tooth to an accident, gum disease, a failed root canal or tooth decay.
By age 74, 26% of adults have lost all of their permanent teeth.
Implant created too large for the socket
Not enough bone or tissue support
Long procedures and numerous appointments
Complications without 3D Imaging
It is important for the Dental Hygienist to understand 3-D imaging in case the Dentist wants them to explain the risks & benefits associated with the treatment plan.
CBCT would be a wonderful investment to any Dental Care Team because the pros outweigh the cons:
Surgical Treatment Planning:
Optimizes Risk Assessment
3-D Cephalometric Tracing
Digital study models
saving your office space
1 low does scan provides every radiograph view needed including:
Soft tissue below the chin and pass the nasium.
Avoids complications that pro-long orthodontic treatment.
Better patient case acceptance
Faster case completion through 3-D planning.
Advantages to Digital Plaster Models
Complex malocclusion's can be better analyzed.
Provides accurate representation of:
Immediate supporting structures
Provides impressions that extend far enough into the sulcus to allow accurate reproduction of all soft tissue anatomy before dental treatment beginnings.
Enhances the diagnosis of cortical bone loss
Provides clear distinction between healthy and degenerative condylar morphologies
Improved detection of osteoarthritic morphology
CBCT in Endodontics
Periapical disease can be accessed and diagnosed sooner
Images of root fractures, root canal anatomy, and alveolar bone resorption are shown in their true size, location, and extent.
True cortical and cancellous bone thickness/density
Relation of root apices to structures such as the
maxillary sinus or inferior alveolar nerve.
