patient specific implant oral maxillofacial surgery
This educational image illustrates the application of 3D-printed polyetheretherketone (PEEK) for patient-specific maxillofacial and cranial implants. Figure (a) displays a mandible reconstruction case, showing a 3D digital schematic alongside a physical PEEK mandible implant. The digital model highlights anatomical positioning relative to the condyles and identifies functional features including 'drainage holes' and 'screw holes.' The physical implant is a tan-colored, U-shaped biocompatible structure with visible circular perforations for drainage and fixation. Figure (b) focuses on neurosurgical reconstruction, featuring a digital skull model with a highlighted left temporal/parietal cranial defect alongside a physical PEEK cranial bone implant. The physical implant is shown post-fabrication on a 3D printing build plate, supported by a vertical lattice-like scaffold. The image demonstrates the use of additive manufacturing to create complex, anatomical geometries for bone replacement in oral and maxillofacial surgery and neurosurgery, emphasizing the transition from virtual design to physical biomedical hardware.
A multi-panel figure illustrating the planning, physical model, and postoperative outcome of a complex patient-specific implant (PSI) for mandibular reconstruction. Panels A and B display 3D digital planning lateral and posterior-lateral views, showing a virtual model of a metallic implant conforming to the mandibular ramus and body. The implant features a characteristic Y-shaped fixation plate at the ramus and multiple circular screw holes for stabilization. Panel C shows the physical metallic implant prototype mounted on a 3D-printed white plastic mandible model, demonstrating the precise anatomical fit. Panel D is a postoperative orthopantomogram (panoramic X-ray) showing the radiopaque implant in situ, extending from the mandibular symphysis to the ramus. The radiographic image confirms the position of the fixation screws and the restoration of mandibular continuity following a segmental resection. This visual material is intended for oral and maxillofacial surgery education, focusing on Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) in reconstructive surgery.
A four-panel composite image documenting the rehabilitation of a terminal edentation in the right mandible (missing teeth 4.5 to 4.8) using a custom-made partially subperiosteal implant. Top left: An orthopantomogram (OPG) shows the radiopaque metallic implant framework secured to the right posterior mandible with multiple osteosynthesis screws, featuring vertical abutment posts for prosthetic attachment. Top right: A 3D-printed anatomical model of the mandible displays the custom CAD/CAM implant framework seated on the alveolar ridge, highlighting its patient-specific morphology. Bottom panels: Intraoperative clinical photographs show the surgical placement of the implant. The metal framework is visible atop the mandibular bone, stabilized by screws within a reflected mucoperiosteal flap. The images demonstrate the close relationship between the custom implant and the remaining natural dentition, with surgical retractors and mirrors providing site exposure. This visual sequence illustrates the workflow from radiological planning to the surgical implementation of subperiosteal implant technology in oral and maxillofacial surgery.
Clinical photograph of a 3D-manufactured patient skull model utilized for surgical planning in oral and maxillofacial surgery. The image shows two views of a transparent anatomical model of a human skull, specifically focusing on the mid-face and mandible with integrated dental arches. Frame (a) demonstrates a patient-specific cutting guide (PSCG) rendered in blue, positioned along the anterior maxilla to facilitate a precise Le Fort I osteotomy. Frame (b) illustrates a patient-specific implant (PSI), also in blue, which is designed for fixation and stabilization following the osteotomy. The model includes detailed brown-colored dentition for accurate occlusal referencing. This surgical simulation tool is used to validate the fit of CAD/CAM components, such as selective laser melted (SLM) hardware, and to coordinate robot-guided laser surgery for correcting skeletal malocclusions. The visualization emphasizes the integration of digital surgical planning with physical anatomical replicas for pre-operative rehearsal and intra-operative guidance.
Educational diagnostic and 3D modeling image illustrating computer-assisted surgery (CAS) planning for a complex midfacial reconstruction following Ewing’s sarcoma resection. Figures A and B demonstrate virtual segmentation and surgical planning through a color-coded schema: the segmented primary tumor is shown in brown, while the planned bony resection margins are in blue. Red markers indicate the surgical cutting guides. For reconstruction, the unaffected left orbit (green) is mirrored to guide the restoration of the right orbital floor using a patient-specific PEEK implant (pink). A purple segment outlines the virtual design for a titanium maxillary reconstruction plate. Figure C presents a grayscale 3D skull model highlighting the finalized patient-specific implants (PSIs) in gold, including the orbital floor component and a large-span midfacial reconstruction plate. The image serves as a detailed example of CAD/CAM technology in oral and maxillofacial surgery, focusing on anatomical mirroring, tumor mapping, and the integration of patient-specific implants to restore both functional and aesthetic facial contours.
This diagnostic image features a 3D medical reconstruction of a human skull, specifically showcasing a Customized Subperiosteal Implant (CSI) applied to an atrophic maxilla. The image demonstrates a dark gray, frame-like metallic structure that is anatomically contoured to the bone surface. Key educational features highlighted include the smooth, rounded transitions between the primary implant frame and the prosthetic connection points, which are encased in red boxes for emphasis. The design lacks sharp angles and exhibits a polished surface texture, which is clinically significant for minimizing soft tissue irritation, reducing the risk of postoperative dehiscence, and preventing biofilm adhesion. Multiple fixation points are visible along the zygomatic and alveolar regions, secured with bone screws. This visual serves as a textbook example of patient-specific implant design in oral and maxillofacial surgery, particularly for complex dental rehabilitation where conventional endosseous implants are contraindicated due to severe bone resorption.
This composite educational image illustrates the pre-operative planning and physical characteristics of a Patient-Specific Implant (PSI) for complex orbital floor and medial wall reconstruction. Panel A displays a multiplanar diagnostic view, combining a 3D volume-rendered CT of the skull with axial, sagittal, and coronal cross-sections. The 3D view shows the red computer-aided design (CAD) of the implant positioned within the left orbit. The 2D views demonstrate the planned implant trajectories (indicated by blue and green lines) relative to the fracture site and surrounding sinus structures. Panels B and C provide clinical photographs of the titanium implant. Panel B shows the superior surface, featuring navigation grooves for intraoperative guidance and manufacturer markings. Panel C reveals the inferior surface, which has been treated with plasma electrolytic polishing (PeP) to create a smooth, biocompatible interface for the orbital bone. The implant includes multiple slots to facilitate tissue integration and drainage. This content is designed for oral and maxillofacial surgery education, focusing on digital surgical planning and implant surface engineering.
This composite image displays a 3D computer-aided design (CAD) of a customized subperiosteal implant (SPI) for maxillary reconstruction, used in cases of severe alveolar bone resorption. Panel (A) provides mirrored oblique views of the bilateral maxillary segments, showing the implant framework (highlighted in yellow) resting on the residual bone of the maxillary arch and zygomatic processes. The bone model is partially transparent, illustrating the orientation of the implant's internal support and the positioning of six downward-projecting cylindrical abutments intended for dental prostheses. Panel (B) presents a frontal (anterior-posterior) view of the midface and skull, demonstrating the complete bilateral SPI framework. The design features lateral wing-like extensions with integrated fixation screw holes for securing the titanium alloy structure to the stable bone of the zygomatic butts and paranasal areas. A centimeter ruler is visible on the left for scale. The visual serves to demonstrate patient-specific implant design and digital planning in maxillofacial prosthodontics and oral surgery.
CAD CAM custom implant mandible reconstruction titanium
This composite of four clinical photographs (A-D) documents the intraoperative stages of a mandibular reconstruction for unicystic ameloblastoma. Panel A shows the initial surgical field with subplatysmal dissection and elevation of a soft tissue flap to expose the left mandible. Panel B illustrates the segmental mandibulectomy performed distal to the second molar, with arrows indicating the osteotomy site created using an oscillating saw. Panel C displays the excision of the pathology, showing the resected bone segment held by surgical instruments. Panel D demonstrates the reconstruction phase, where a custom-made, patient-specific titanium mesh implant is positioned in the mandibular defect. The implant is secured to the stable bone segments using multiple titanium fixation screws. The series illustrates a radical surgical approach to mandibular lesions, focusing on achieving clear margins and immediate functional reconstruction using CAD-CAM technology to restore facial contour and jaw continuity.
A close-up clinical photograph of a cadaveric specimen demonstrating a mandibular reconstruction interface. The image shows a metallic, custom-manufactured titanium implant designed for a 'tube-in-tube' connection with a resected bone stump. The bone has been surgically prepared with a circular step, creating a precise diameter reduction that allows the implant to sleeve over the stump with a high degree of congruency. The implant features a smooth, machined finish and a contoured edge that mimics the anatomical cross-section of the mandible. Several small, circular pre-drilled holes are visible along the perimeter of the implant’s overlapping collar, intended for secondary stabilization using surgical fixation screws. This visual highlights advanced maxillofacial surgical techniques using CAD/CAM technology and laser sintering (LaserCUSING®) to achieve high-precision fitting in ablative tumor surgery reconstructions. The educational focus is on the biomechanical stability and anatomical integration of patient-specific implants in head and neck surgery.
Educational photographs showcasing a 3D-printed stereolithographic (STL) model and custom-fabricated titanium meshes used for complex maxillofacial reconstruction. The white, opaque resin model represents a human mandible with visible anatomical landmarks, including the condylar processes, coronoid processes, rami, and mandibular body. Image (A) shows an anterior-oblique view, while image (B) provides a superior-oblique view of the horseshoe-shaped jaw structure. Adapted to the anterior and lateral mandibular regions are two CAD/CAM titanium meshes featuring a characteristic purple-metallic hue. These meshes exhibit a porous texture with regularly spaced 1.5 mm perforations to facilitate vascularization and bone graft integration. The meshes are precision-contoured to bridge a vertical bone discrepancy, specifically following a two-segment fibula flap reconstruction for ameloblastoma. Multiple screw holes are visible at the inferior margins, demonstrating the mechanical fixation strategy for maintaining an iliac crest bone graft. The visual illustrates the integration of virtual surgical planning (VSP) in treating large mandibular defects to restore vertical dimension and support future dental implant placement.
