Ameloblastoma is a locally aggressive, benign odontogenic tumor that often presents in the posterior region of the mandible. Despite its benign histology, the lesion’s infiltrative growth pattern can result in significant destruction of the surrounding bone and adjacent structures—most notably the ramus, coronoid process, and even the condyle.
In contemporary oral radiology, the integration of three-dimensional diagnostic modeling has transformed how such complex pathologies are visualized and understood.
Understanding Ameloblastoma: A Radiological Perspective
On radiographic examination, ameloblastomas often present as multilocular radiolucencies with a “soap-bubble” or “honeycomb” appearance. Conventional 2D imaging aids in initial detection, but the true extent of cortical perforation, internal septation, and involvement of vital structures can be underestimated.
Cone-beam computed tomography (CBCT) bridges this gap by offering volumetric visualization. The data can be processed to create a high-fidelity diagnostic 3D model, enabling clinicians to:
- Assess the lesion’s full spatial relationship with mandibular landmarks
- Evaluate bone expansion, thinning, and cortical breach
- Communicate pathology extent more clearly with surgeons and patients
The Role of Diagnostic 3D Models
Transforming CBCT datasets into 3D models brings pathology to life. Through segmentation and surface reconstruction, clinicians can isolate the lesion, adjacent anatomy, and reconstruct precise digital replicas. Such diagnostic 3D models offer:
- Enhanced visualization of lesion boundaries and anatomical destruction
- Pre-surgical planning support, helping surgeons anticipate resection margins
- Educational value, providing real-case models for academic discussions
- Patient communication, translating complex imaging data into tangible understanding
These models can also be exported to 3D printers, allowing hands-on surgical simulation or demonstration in multidisciplinary case discussions.
From Data to Diagnosis: The Digital Workflow
- CBCT Acquisition – Optimized field of view (FOV) covering the mandible and lesion region.
- Segmentation and Reconstruction – Using software like 3D Slicer or Mimics to isolate the lesion and bone.
- 3D Visualization and Analysis – Rendering models for evaluation and annotation.
- Optional 3D Printing – Creating tangible models for planning or teaching.
This workflow enhances diagnostic clarity, fosters interdepartmental collaboration, and elevates the standard of care.
Clinical Impact and Future Outlook
As digital dentistry evolves, 3D diagnostic models will continue to redefine radiologic interpretation and surgical planning. For extensive lesions like ameloblastoma, they provide a new dimension—literally—to radiographic diagnosis.
In upcoming years, integration with AI-based segmentation and virtual planning tools will further streamline the process, making 3D diagnostic modeling a core component of precision oral radiology.
With over a decade of experience in dentistry, I specialize in diagnosing a wide range of oral diseases and have developed a deep passion for dental imaging. My interest in CBCT reporting and digital implantology led me to become a pioneer in the concept of diagnostic 3D modelling. Throughout my career, I have supported and educated numerous dentists in mastering CBCT interpretation, virtual implant planning, and the latest advancements in 3D printing for dental applications.
