The Use of 2D and 3D Imaging Modalities and Its Influence on Diagnosis and Treatment Planning in Orthodontics
|ClinicalTrials.gov Identifier: NCT01246830|
Recruitment Status : Completed
First Posted : November 23, 2010
Last Update Posted : December 3, 2014
- Will the panoramic images derived from cone beam CT data give better diagnostic ability than conventional panoramic radiographs?
- Will 3D cephalometric analysis offer the orthodontists and surgeons better information for treatment planning?
- Will the 3D cephalometric analysis give more accurate treatment plan and better treatment outcome?
General hypothesis and special aims
- To compare 2D versus 3D cephalometric analysis: treatment planning and therapeutic outcome.
- To determine the accuracy and diagnostic ability and usability of the 3D cephalometric analysis.
- To evaluate the diagnostic ability and usability of the panoramic image derived from cone beam CT data as compared to 2D panoramic images.
- To evaluate the value of the cone beam CT data in cephalometric analysing process for orthodontic and maxillofacial surgery treatment.
- The availability of the 3D cephalometric analysis influences the orthodontic and maxillofacial treatment plan and decision, and might change the treatment outcome.
- Panoramic images derived from cone beam CT data may provide equal information for diagnosis as conventional panoramic images.
- Cone beam CT will be able to replace "classic orthodontic imaging" being more time and dose efficient and having a beneficial effect on treatment outcome.
