Virtual Preoperative Planning and Intraoperative Navigation in Facial Prosthetic Reconstruction: A Technical Note.

This technical protocol outlines the use of computer-assisted image-guided technology for the preoperative planning and intraoperative procedures involved in implant-retained facial prosthetic treatment. A contributing factor for a successful prosthetic restoration is accurate preoperative planning to identify prosthetically driven implant locations that maximize bone contact and enhance cosmetic outcomes. Navigational systems virtually transfer precise digital planning into the operative field for placing implants to support prosthetic restorations.

Management of central giant cell granuloma with subcutaneous denosumab therapy.

Purpose: In recent years, the treatment of central giant cell granuloma (CGCG) has become focused on the inhibition of osteoclast differentiation and proliferation. Medications that were developed for the treatment of giant cell tumor of bone and bone resorption from metastatic skeletal disease have shown some success in the treatment of CGCG. The present report describes 2 cases of CGCG of the mandible that were treated effectively with subcutaneous denosumab.

Applications of surgical navigational systems for craniofacial bone-anchored implant placement.

The following case reports describe the use of computer-assisted image-guided surgery to plan and place craniofacial bone-anchored implants (CBAI) for facial prosthetic reconstructions. During virtual planning, the soft tissue and bone visualizations are segmented from spiral computed tomography data and the patient's normal anatomy is mirrored onto the skull of the defect side, thus providing the ability to visualize the future prosthetic form. CBAI are planned in the anatomical area that leads to the best cosmetic results.

Early clinical experience with a new one-piece implant system in single tooth sites.

Purpose: To evaluate the clinical efficacy of a new 1-piece implant in single tooth sites.

Materials And Methods: Early clinical results were evaluated through observation and collection of survival data for 45 1-piece Direct implants (Nobel Biocare, Yorba Linda, CA). Patients ranged in age from 19 to 54 years, of which 23 were women and 12 were men.

Evaluation of ocular changes secondary to blowout fractures.

There has been extensive debate over the standard of care of orbital fractures. Entrapment, diplopia, and hypoglobus, with or without enophthalmos, are the most common clinical indications for surgical intervention. Evaluation of these injuries is often limited in the early postinjury period because of edema.

Proximal tibia bone harvest: review of technique, complications, and use in maxillofacial surgery.

Autologous bone grafts for alveolar ridge augmentation are the gold standard for restoring atrophic residual ridges in preprosthetic surgery. Many indications, donor sites, and techniques have been reported. The purpose of this article is to review the anatomy, surgical technique, and potential complications associated with proximal tibia bone harvest.

Predicting lower lip and chin response to mandibular advancement and genioplasty.

The purposes of this retrospective study were to examine the multidimensional nature of soft tissue changes associated with mandibular advancement and genioplasty and to develop predictive models. Longitudinal lateral cephalograms of 62 nongrowing patients (27 men and 35 women) were taken in centric relation with the lips in repose within 4 weeks before surgery and at least 6 months postoperatively (median postsurgical duration was 11 months). The mandibular incisor and pogonion were advanced surgically approximately 6 mm and 11 mm, respectively.

Bone reduction surgical guide for the Novum implant procedure: technical note.

The Novum System offers a unique opportunity to create a definitive, immediately loaded fixed prosthesis on the edentulous mandible for patients who meet specific presurgical criteria. Since this system is based on precisely placed implants and prefabricated bar structures, the surgical techniques are critical in obtaining a satisfactory result. It is especially important that the bone reduction required to create space for the implants and bar assembly be in the proper plane and deep enough to leave room for eventually setting and processing teeth.
