Összefoglaló szövege

Introduction: In advanced cases of periodontal tissue breakdown, it is difficult to determine the true defect morphology and extent of complex defects on two-dimensional (2D) intraoral radiographs, consequently the surgical intervention and regenerative strategy is also difficult to plan. Various surgical fields, such as: orthopedic surgery, cardiac surgery and cranio-maxillofacial surgery, utilize three-dimensional (3D) planning and virtual simulation on digital and 3D printed anatomical models for the planning of surgical interventions. Anatomically accurate 3D models are created from DICOM (Digital Imaging and Communications in Medicine) datasets of MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) images.
Aim: To implement radiographic image processing techniques used in cardiovascular surgical planning, to create anatomically accurate 3D models of teeth and periodontal defects, for planning and digital simulation of the procedure.
Materials and Methods: 4 patient were included in this examination. High definition Cone-beam CT (CBCT) is taken preoperatively. In order to get the best image quality, cotton rolls are placed in the vestibule to retract the buccal mucosa, and metal artifact reduction algorithms are used if necessary. Semi-automatic and manual segmentation tools are used to select the regions of interest (ROI), in this case teeth and bone. 3D polygon model is generated from the ROIs. Further refinement and preparation for 3D printing is done in CAD (Computer Aided Design) based software. Models are manufactured with selective laser sintering (SLS). Measurements were taken both intraoperatively and, on the 3D printed models at decisive anatomical landmarks.
Results: Models were used in the planning of the surgical procedure. Better understanding of the defect morphology allowed for a less invasive and faster surgical procedure. Knowing the exact 3D defect morphology, the extension of the flap could be kept minimal compared to the extension of the defect.
Conclusion: Digital three-dimensional modelling of teeth and alveolar bone in periodontally involved patients is a new method, that can be utilized in periodontal diagnostics, treatment planning and surgical simulation. However, to validate the accuracy of this method, preliminary methodological studies have to be conducted first.
