Evaluation of the temporomandibular joint morphology and condylar position with cone-beam computerized tomography in patients with internal derangement.

Objectives: To evaluate the relationship between internal derangement and morphological features of the temporomandibular joint by comparing joint morphology between patients with ID and control patients.

Methods: The current study prospectively is evaluated the cone-beam computed images of 106 ID patients and 122 patients with asymptomatic joints; recorded angular and linear measurements. The relationships between these measurements and ID are investigated; the differences between the two groups using paired t tests.

Influence of Orthognathic Surgery on Oral Health and Quality of Life.

Orthognathic surgery is a common treatment modality for moderate to severe dentofacial deformities. This study aimed to determine the early postoperative changes in quality of life (QoL) after orthognathic surgery.Twenty patients were evaluated preoperatively (T0), postoperatively after 1 month (T1), and postoperatively after 3 months (T2).

Reconstruction and Implant-Supported Rehabilitation of an Iatrogenically Caused Maxillary Alveolar Defect.

Defects of the oral and maxillofacial region may arise from several reasons such as trauma, infection, cyst, tumor, medication related osteonecrosis of the jaw, and misuse of some irritant agents. For reconstruction, autogenous grafts remain the gold standard among the alternatives. In our case, a 42-year-old woman referred to our clinic for implant-supported fixed bridge rehabilitation of her edentulous and defected left 2nd premolar and 1st molar region.

Evaluation of patient satisfaction after botulinum toxin A injection for the management of masticatory myofascial pain and dysfunction - A pilot study.

: To evaluate patient satisfaction with botulinum toxin type A injections for the management of masticatory myofascial pain and dysfunction. : The study group included 25 patients with myofascial pain and dysfunction. Maximum mouth opening (MMO), measured with a ruler, and pain, measured on a 10-cm visual analog scale (VAS), were assessed before treatment and six weeks after treatment.

Effects of Piezoelectric Surgery on Bone Regeneration Following Distraction Osteogenesis of Mandible.

The aim of this study is to compare the bone healing in the distraction gap following the osteotomy performed with piezoelectric and conventional devices for the distraction osteogenesis in the rabbit mandibles. Twelve rabbits were randomly divided into 2 groups; 6 for piezoelectric device and 6 for rotary instruments. After 3 days of latency period, distraction was started at a rate of 1 mm per day for 10 days.

Spontaneous Healing of Mandibular Noncontinuous Defect Caused by Medication-Related Osteonecrosis of the Jaw.

Background: Bisphosphonates are used throughout supportive cancer therapies for the treatment of osteoporosis and metastatic bone diseases, but they invariably induce medication-related osteonecrosis of the jaw (MRONJ). This medicational modality may induce consequential losses that can lead to spontaneous or surgical therapy related bone fractures or defects. MRONJ stages and treatment alternatives are described in the current procedures.

Efficacy of platelet rich fibrin in the reduction of the pain and swelling after impacted third molar surgery: randomized multicenter split-mouth clinical trial.

Background: Impacted third molar removal is a routine procedure in oral and maxillofacial surgery. Platelet-rich fibrin (PRF) is a second generation platelet concentration which is produced by simplified protocol. The aim of this study was to assess the effectiveness of PRF in the healing process by evaluating the changes in pain and swelling after third molar surgery.

Finite-Element Analysis of a New Designed Miniplate which is Used via Intraoral Approach to the Mandible Angle Fracture: Comparison of the Different Fixation Techniques.

The mandible is the largest facial bone as well as the most commonly fractured bone in the maxillofacial region. Despite numerous studies conducted to identify optimal treatment modalities and plates configurations for intraoral and transoral approaches, no definitive conclusion has been reached. This study used finite element analysis (FEA) to assess 4 scenarios for treatment of an angle fracture (6-hole noncompression miniplate; 6-hole single plate/Champy's technique, 3D strut plate; 2 parallel 4-hole noncompression miniplates).

Evaluation of preoperative model surgery and the use of a maxillary sinus surgical template in sinus floor augmentation surgery.

Maxillary sinus augmentation is an accepted technique for dental implant placement in presence of insufficient maxillary bone. There are various techniques in the literature, either by crestal or lateral approach in maxillary sinus augmentation that have high percentage of success, while all have complications. Schneiderian membrane perforation is the most common complication encountered during surgery.

Biomechanical evaluation of malleable noncompression miniplates in mandibular angle fractures: an experimental study.

The purpose of this experimental study was to test the reliability of a single malleable titanium miniplate using Champy's method of fixing fractures of the mandibular angle. Eighteen sheep hemimandibles were used to evaluate 2 plating techniques. The groups were tested with either a single non-compression titanium miniplate or a single malleable titanium miniplate.
