Official title
Zero Echo Time MR for the Assessment of Maxillary Sinus, Bone and Soft Tissues in the Maxillary Premolar and Molar Areas
Overview
The aim of this study is to evaluate the efficacy of zero echo time magnetic resonance imaging (ZTE MRI) as an ionizing radiation-free diagnostic method to evaluate both hard and soft tissues and maxillary sinus region before dental implants in the posterior maxillary region.
Detailed description
Today, cone beam computed tomography (CBCT) is routinely used to evaluate the bone structure of the surgical area, to define the anatomical landmarks in the area, to detect variations, if any, and to evaluate the presence of pathologies before dental implant treatment. However, soft tissue evaluations, which are an important factor in treatment planning and the success of the treatment, cannot be performed adequately on CBCT images, and in addition, there is a significant increase in the exposure of patients to ionizing radiation. Using zero echo time magnetic resonance imaging (ZTE MRI) as a diagnostic tool that does not involve ionizing radiation in dentistry may provide a solution to this situation.
The aim of the present project is to evaluate the efficacy of ZTE MRI as an ionizing radiation-free diagnostic method to evaluate both hard and soft tissues and the maxillary sinus region before dental implants in the posterior maxillary region. For this purpose, it is planned to examine CBCT and ZTE MRI images of patients planned for dental implant treatment, to perform digital measurements with an intraoral scanner and intraoral direct measurements during surgery and to compare the results of bone and soft tissue measurements obtained.
Primary outcome measures
- Evaluation of maxillary sinus area with ZET-MR [Time frame: Baseline-18 months]
- Evaluation of alveolar bone dimensions in maxillary premolar and molar areas with ZET-MR, CBCT and directly [Time frame: Baseline-18 months]
- Evaluation of soft tissue for dental implant planning Evaluation of gingival tissue dimensions in maxillary premolar and molar areas with ZET-MR and directly during surgery [Time frame: Baseline -18 months]
