Clinical and radiographic assessment of patient-specific transantral reconstruction of orbital floor fractures: A case series.

To clinically and radiographically evaluate patient-specific titanium meshes via a trans-antral approach for correction of enophthalmos and orbital volume in patients with recent unilateral orbital floor fracture. Seven patients with unilateral orbital floor fractures received patient-specific titanium meshes that were designed based on a mirror-image of the contralateral intact orbit. The patient-specific implants (PSIs) were inserted via a trans-antral approach without endoscopic assistance.

Guided Bone Regeneration for Horizontal Maxillary Alveolar Ridge Augmentation Using Patient-Specific Solid Titanium Barriers: A Case Series.

Purpose: To assess the radiographic and histomorphometric outcomes of horizontally augmented maxillary alveolar ridges using solid nonperforated customized titanium barriers.

Materials And Methods: This case series study included patients who received guided bone regeneration treatment in the anterior maxillary esthetic zone (eight patients, 18 dental implants) using patient-specific solid titanium barriers loaded with a mix of autogenous and xenogenic particulate bone grafts. A radiographic comparison between three time periods (immediately postoperative, 4 months, and 10 months) included software-aided calibration of the linear changes in the horizontal dimensions on CBCT cross-sectional cuts after being standardized.

Patient-specific alloplastic endoprosthesis for reconstruction of the mandible following segmental resection: A case series.

Reconstruction of mandibular discontinuity defects remains a challenge for maxillofacial surgeons. Despite vascularized free flaps representing the current gold standard for managing such defects, the search continues for other less morbid yet predictable interventions. This study aimed at reviving the idea of alloplastic mandibular endoprosthesis as a treatment modality for reconstruction of segmental mandibular defects following eradication of benign tumors.

Quality of life after different approaches of orthognathic surgery: a randomized controlled study.

Background: Over the last decade, the accuracy of 3D computer-assisted orthognathic surgery has been extensively investigated. However, patient-reported outcome measures have been rarely reported for this technology. This study aimed to assess quality of life following orthognathic surgery using CAD/CAM bone splints compared to the classic occlusal wafers in patients with dentofacial deformities.

Assessment of vertical ridge augmentation and labial prominence using buccal versus palatal approaches for maxillary segmental sandwich osteotomy (inlay technique): A randomized clinical trial.

Background: The aim of this study was to evaluate the final vertical gain at the deficient anterior maxillary alveolar ridges using buccal versus palatal approaches for maxillary segmental sandwich osteotomy (inlay technique). This is a single-institutional randomized comparative clinical trial.

Material And Methods: The study population was 16 patients with edentulous anterior maxillary alveolar ridges (40 implant sites).

Midfacial Reconstruction - A Systematic Review.

Aim: Different lesions affecting the midfacial regions require surgical reconstruction. The aim of this study was to assess the different methods used in midfacial reconstruction after maxillectomy procedures. The various reported surgical reconstructive techniques focusing on the esthetic and functional outcomes are to be reviewed in this article.

Clinical and radiographic evaluation of a computer-generated guiding device in bilateral sagittal split osteotomies.

The bilateral sagittal split osteotomy (BSSO) is one of the main orthognathic surgery procedures used for managing skeletal mandibular excess, deficiency or asymmetry. It is known to be a technique-sensitive procedure with high reported incidences of inferior alveolar nerve injury, bad splits and post-surgical relapse. With the increasing use of computer-assisted techniques in orthognathic surgery, the accurate transfer of the virtual plan to the operating room is currently a subject of research.

Nongrafted sinus floor elevation with a space-maintaining titanium mesh: case-series study on four patients.

Purpose: Numerous materials and techniques have been introduced to augment the maxillary sinus floor for future dental implant placement. Schneiderian membrane tenting above simultaneously placed implants proved to be a successful technique. The present study investigated the use of a titanium micromesh for lateral-window sinus floor elevation without bone grafting.

Computer-guided rapid-prototyped templates for segmental mandibular osteotomies: a preliminary report.

Background: Segmental mandibular resection represents a challenge to maxillofacial surgeons in terms of accurate contouring of reconstruction plates, restoration of mandibular symmetry and maintaining accurate condylar position in the glenoid fossae.

Methods: We propose a CAD/CAM technique for fabricating patient-specific templates to symmetrically prebend reconstruction plates, guide osteotomies and reposition the condylar process in the proximal edentulous segment in its preoperative position. We operated on two patients using this new technique.
