Surgical Management of Lateral Orbital Contour Following Le Fort III Distraction.

Le Fort III distraction is indicated for the management of skeletal malocclusions, midface hypoplasia, and exorbitism and has been found to be a safe procedure with predictable results. Although variation in the placement of the lateral orbital osteotomy has been described, the classic osteotomy divides the zygomatic arch, crosses the lateral orbital rim, transverses the orbital floor, and ends in the midline. Distraction of this segment may lead to a palpable, and sometimes visible, step deformity between the lower and upper segments of the lateral orbital wall. The authors present a novel approach to the management of the lateral orbital wall step deformity following Le Fort III distraction.

Advanced dental implant placement techniques.

The availability of in office Cone Beam CT (CBCT) scanners, dental implant planning software, CAD CAM milling, and rapid printing technologies allow for the precise placement of dental implants and immediate prosthetic temporization. These technologies allow for flapless implant placement, or open flap bone reduction for "All on 4" techniques with improved preoperative planning and intraoperative performance. CBCT permits practitioners in an office setting with powerful diagnostic capabilities for the evaluation of bone quality and quantity, as well as dental and osseous pathology essential for better informed dental implant treatment. CBCT provides the convenience of in office imaging and decreased radiation exposure. Rapid printing technologies provide decreased time and high accuracy for bone model and surgical guide fabrication.

Cone beam computed tomography scanning and diagnosis for dental implants.

Cone beam computed tomography (CBCT) has become an important new technology for oral and maxillofacial surgery practitioners. CBCT provides improved office-based diagnostic capability and applications for surgical procedures, such as CT guidance through the use of computer-generated drill guides. A thorough knowledge of the basic science of CBCT as well as the ability to interpret the images correctly and thoroughly is essential to current practice.

Prosthodontic Considerations in Post-cancer Reconstructions.

The restoration of function after oncologic surgery of the oral cavity constitutes one of the major challenges facing head and neck oncology. Within the general objective of securing esthetic as well as functional reconstructions, dental rehabilitation is crucial for achieving a good outcome. Adequate dental rehabilitation allows the patient to chew food and considerably improves speech and swallowing. These reconstructions will be driven biologically or prosthetically following surgical design and outcome.

Digital technologies for dental implant treatment planning and guided surgery.

Oral and maxillofacial surgeons now have extraordinary imaging, software planning, and guide fabrication technologies at their disposal to aid in their case selection, clinical decision making, and surgical procedures for dental implant placement. Cone beam CT has opened a new era of office-based diagnostic capability and responsibility. Improved clinical experiences and evidence-based superior outcomes can be provided with confidence to patients when CT-guided dental implant surgery is used.
