Summary
Computer-aided design and manufacturing (CAD/CAM) enhances oral surgery by providing 3D models and custom tools. This technology improved the management of nonsyndromic metopic synostosis with specialized surgical guides and implants.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Medical Device Design
Background:
- Computer-aided design and computer-aided manufacturing (CAD/CAM) is increasingly utilized in oral and maxillofacial surgery.
- Advancements in 3D modeling, cutting guides, and customized surgical instruments offer significant potential for surgical procedure enhancement.
Purpose of the Study:
- To illustrate the application of CAD/CAM technology in managing a specific case of nonsyndromic metopic synostosis.
- To detail the creation of specialized tools for improved surgical outcomes.
Main Methods:
- Utilized CAD/CAM to design and fabricate a cranial cutting guide.
- Developed custom orbital protectors and a 3D model of predicted postoperative meninges.
- Created a template frontal bar for precise bone recontouring.
Main Results:
- The application of CAD/CAM facilitated the creation of patient-specific surgical aids.
- These aids allowed for enhanced precision in cranial and frontal bar recontouring.
- The 3D meningeal model enabled pre-operative planning for bone adjustments.
Conclusions:
- CAD/CAM technology significantly improves the management of complex craniofacial anomalies like nonsyndromic metopic synostosis.
- Customized surgical guides and implants derived from CAD/CAM enhance surgical accuracy and patient outcomes.
- This approach represents a valuable advancement in personalized surgical treatment planning.

01:14Cranial Bones: Superior and Posterior View
4.7K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
4.3K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
9.9K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
