3D technology in clinical practice Flashcards
what are the applications of 3D technology in oral and maxillofacial surgery?
What are applications of 3D technology in other clinical fields?
How does one built a virtual patient?
- obtain imaging of –> bony tissue + soft tissue + dentition
What are the preparation steps for 3D planning and analysis?
- obtain images
- display pre-operative
- planning - boy structures
- determined plan of change - bony structures
- soft tissue simulation
- design and printing of the necessary material
When are then different imaging modalities –> (CB)CT, intra-oral scanning, and 3D photogrammetry used?
CBCT –> bony structures
Intra-oral scanning –> dentition - plaster models
- scan intra-oral room to produce model
3D photogrammetry –> soft tissue
What is a CBCT?
Cone beam CT imaging
- Cone beam CT scanners use a fluoroscopy tube, which generates less radiation but still captures incredibly high-resolution radiographs (compared to CT)
- all bones, nerves, and soft tissues in high detail
Why do patient undergo jaw surgery?
- To correct the position of the jaw(s)
- Malocclusion (overbite/underbite)
- Sleep apnea (OSA)
- Growth disorders (e.g. asymmetry)
What is a wafer?
a wafer is a thin piece of plastic which fits between and indexes the occlusal surfaces of the maxillary and mandibular teeth.
The appliance has three functions:
1. it positions the jaws relative to one another
2. it prevents sliding movement during inter-maxillary fixation
3. it prevents unwanted orthodontic movement
What is “Splintless surgery” in dental/ raw surgery?
- state of the art + expensive
–> without wafers –> used when eg. no death as guidance - virtually planned, computer-aided design of individual guides, patient-specific fiction implants (3D printed)
What are the big steps in Patient Specific Solutions ?
Diagnosis –> Planning –> Treatment –> Evaluation
