Critical maxillofacial bone fractures do not heal spontaneously, thus, often there is a need to facilitate repair via surgical intervention. Gold standard approaches, include the use of autologous bone graft, or devices supplemented with osteogenic growth factors and bone substitutes. This research aimed to employ a critical size calvaria defect mo...

Objectives: First, to investigate the clinical outcome of 'proportional condylectomy' for patients with active unilateral condylar hyperplasia without complementary treatment by intermaxillary elastics and, second, to examine their level of satisfaction regarding function and esthetics. Study design: A retrospective observational descriptive stu...

Purpose: The purpose of this study was to examine whether the use of short dental implants with an expandable compressive design could be a proper alternative to the conventional sinus elevation procedure in cases of deficient alveolar ridge height in the posterior maxillary area. Materials and methods: Fifty patients with 73 short dental implan...

Objective To examine the effectiveness of an empiric protection protocol during oral surgical treatments in a COVID-19 pandemic area and to evaluate the potential effect of postponed dental procedures on the frequency of facial infections during a lockdown period.Methods We performed a retrospective analysis of a case series of a broad-spectrum of...

Objectives The current study was designed to investigate the correlation between the bony morphology of the mandibular condyle and the occurrence of TMJ idiopathic anterior dislocation. Study Design A comparative retrospective study was conducted amongst 14 patients presenting idiopathic anterior dislocations (study group) and 15 patients who did...

Objectives: The current study was designed to investigate the correlation between the bony morphology of the articular eminence and the occurrence of idiopathic anterior TMJ dislocation. Study Design: A comparative retrospective study was conducted amongst 14 patients presenting idiopathic anterior dislocations (study group) and 14 patients who did...

Localized vertical bone defects within the anterior mandibular alveolar ridge frequently pose a unique challenge for functionally and aesthetically pleasing rehabilitation of this area. Causes for significant bone loss in this region may include periodontal disease, postextraction atrophy, trauma, and orthodontic treatment. In the presence of such...

Displaced dental implants in the mandible may constitute a clinical challenge for both physicians and patients. The complex anatomy of the floor of the mouth, together with its subsequent violation due to implant displacement makes implant allocation and retrieval a challenging procedure. Computerized navigation surgery (CNS) has been previously de...

Purpose: To evaluate the use of a nonperforated titanium occlusive device over a bone morphogenetic protein-2 in an absorbable collagen sponge (BMP-2/ACS) in grafting the bone around high-profile (ie, supracrestal) dental implants in rabbit tibiae. Materials and methods: Eight New Zealand white rabbits were used for the experiment. Two implants...

Ameloblastic fibrosarcoma (AFS), ameloblastic fibro-dentinosarcoma, and ameloblastic fibro-odontosarcoma (AFOS) are rare malignant variants of combined odontogenic tumors. They may arise de novo or in a pre-existing benign tumor such as an ameloblastic fibroma (AF). AFS and AFOS occur mostly in young adults (mean ages, 27 and 30 years, respectively...

The aim of this report was the clinical and histologic characterization of necrotizing sialometaplasia. We performed a retrospective case series analysis. The study included 4 women 29-71 years old. Possible contributing factors (drugs, alcohol abuse, bulimia, smoking, and pancreatic cancer) were identified. Patients presented with unilateral or bi...

Nodular fasciitis is a benign non-neoplastic myofibroblastic proliferation, involving the head in 7% to 20% of cases. Intravascular fasciitis (IVF) is a rare variant, with a unique intravascular growth pattern. Only 4 maxillofacial cases have been previously reported. We describe a 58-year-old woman with a rapidly growing, hard, mobile buccal submu...

Purpose: It is hypothesized that local application of statins positively affects bone formation. The aim of this study was to evaluate the potential effect of topical slow-release simvastatin as a bone substitute on the healing of bone defects in rat tibia. Materials and methods: Granules of slow-releasing hydroxypropyl methylcellulose, with or...

Loss of alveolar vertical height is one of the most challenging conditions in the field of implantology. A few augmentation techniques have been proposed to address this challenge, including guided bone regeneration, alveolar distraction osteogenesis, sandwich osteotomies and autogenous block grafting. This is a pre-clinical study of lengthening th...

The initial evaluation and treatment of trauma victims should follow a planned approach, as delineated by the Advanced Trauma Life Support protocol, with the main concern securing a patent airway. When trauma has been associated with maxillofacial injury, it can complicate airway management owing to aspirated avulsed teeth or dental prosthetic devi...

The island osteoperiosteal flap (I-flap) is introduced as a modified alveolar split bone grafting technique used to gain width and modify the facial or buccal bone plate position. Three case examples are shown as well as animal histology indicating the possible development of this new surgical procedure as an adjunct for alveolar augmentation and i...

To evaluate the effect of informed consent on stress levels associated with removal of impacted mandibular third molars. A total of 60 patients scheduled for extraction of impacted mandibular third molars participated in this study. The patients were unaware of the study's objectives. Data from 20 patients established the baseline levels of electro...
