Patients who have undergone maxillary resection procedures are rehabilitated with dental obturators or microvascular reconstruction. This case report describes implant-supported prosthetic rehabilitation of a patient who underwent maxillary resection because of squamous cell carcinoma. After maxillectomy surgery, the patient was rehabilitated using a surgical obturator for 1 week, followed by an interim obturator until the surgical field was completely healed.

Objective: The purpose of this study was to measure the nasal airflow resistance of operated unilateral cleft lip and palate (UCLP) patients using the anterior rhinomanometry method compared with non-cleft skeletal class III individuals with isolated maxillary hypoplasia serving as the control group.

Material&methods: Sixteen UCLP patients who have undergone lip and palate reconstructions and alveolar cleft grafting but not advanced surgeries as the study group and 16 non-cleft skeletal class III participants as the control group (corresponded for age and sex to the study group) were included in this prospective study. All of the patients had class III occlusion due to isolated maxillary hypoplasia.

Background: Periapical surgery is now a reliable therapeutic procedure for the treatment of teeth with periapical lesions, particularly when orthograde retreatment is problematic. However, little information is available regarding treatment planning of cases referred for periapical surgery. Therefore, this study was conducted to analyze and evaluate the factors that affect the decision-making process for periapical surgery.

Purpose: The purpose of this study is to suggest a patient-specific osteotomy line to optimize the distractor position and thus to minimize the disadvantages of conventional mandibular distraction osteogenesis (MDO) protocols. In addition, this study also aims to compare the conventional MDO protocols with the new MDO protocol proposed in this study in terms of both orthodontic outcomes and mechanical effects of osteotomy level on callus stabilization by means of the finite element method.

Methods: A preoperative patient-specific 3-dimensional bone model was created and segmented by using computed tomography images of an individual patient.

Purpose: The aim of this study was to examine the effects of bimaxillary orthognathic surgery on pharyngeal airway space (PAS) and respiratory function during sleep.

Materials And Methods: The subjects were 21 patients with class III skeletal relationship, and all of the patients underwent bimaxillary surgery (Le Fort I advancement and bilateral sagittal split ramus setback osteotomies simultaneously). Pharyngeal volumes of nasopharyngeal (V-NPA), retropalatal (V-RPA), retrolingual (V-RLA), oropharyngeal (V-ORO) and total pharyngeal airways (V-TOT); minimum axial areas of retropalatal (MA-RPA), retrolingual (MA-RLA) and oropharyngeal airways (MA-ORO); and position of the hyoid were studied in order to detect dimensional PAS changes using cone-beam computed tomography (CBCT) with Dolphin 11.

The purpose of this study was to evaluate the efficiency of platelet-rich fibrin usage in the treatment of alveolar cleft with iliac bone graft by means of volumetric analysis. In this study, 22 patients with alveolar clefts-including 13 unilateral and 9 bilateral-were treated with anterior iliac crest bone grafts. Patients were divided into 2 groups as control (group A) and platelet-rich fibrin (group B) groups.

Objective: We assessed whether ultrasonography (US) can be used in combination with cone beam computed tomography (CBCT) to image intraosseous jaw lesions.

Material And Methods: Using CBCT and US, we evaluated 123 lytic intraosseous jaw lesions diagnosed in 121 patients with guidance from the CBCT findings. The lesions were classified into two groups based on histopathological evaluation: (1) cysts and (2) tumors and tumor-like lesions.

The purpose of this study was to evaluate the sufficiency of the mandibular symphysis as a donor site for unilateral and bilateral alveolar grafting, measuring both the alveolar cleft volume and maximum bone graft volume that can be harvested from the mandibular symphysis using 3-dimensional computed tomography (CT) and software in children and adults. Computed tomography data obtained from 20 unilateral and bilateral cleft lip palates patients in the preoperative period were used in this study. The patients were divided into 2 groups: children (female, n = 5; male, n = 5) and adults (female, n = 5; male, n = 5).

Purpose: To evaluate quality of life (QoL) from a broad perspective by a comparison of Turkish patients undergoing orthognathic surgery to correct Angle Class III skeletal deformity with a control group composed of participants without dentofacial deformity using general health, generic oral health, and condition-specific QoL approaches.

Materials And Methods: Thirty patients who underwent orthognathic surgery to correct Class III relations (monomaxillary and bimaxillary groups) and 30 participants with Class I skeletal structure and good dentofacial harmony (control group) were evaluated. Condition-specific QoL through a 22-item Orthognathic Quality of Life Questionnaire (OQLQ), generic oral health-related QoL through a 14-item Short-Form Oral Health Impact Profile (OHIP-14), and generic health-related QoL through a 36-item Short-Form Health Survey (SF-36) were assessed.

Objective: The aim of this study was to identify the prevalence, associated pathology and symptoms, and treatment of impacted premolars in a Turkish population.

Study Design: This retrospective study examined panoramic radiographs and clinical records of 9,000 patients who presented consecutively at our oral and maxillofacial surgery clinics between January 1998 and January 2009. In addition to demographic data (patient sex and age), data was compiled on the number and location of impacted missing maxillary and mandibular premolars, retained deciduous molars, associated pathologies and symptoms, and treatment methods.

Female breast cancer is one of the major causes of death among women. Metastatic tumors to the maxillo-facial bones are rare. We present diagnosis and treatment of multiple metastatic invasive ductal carcinoma involving massive and early stage the left half of the mandibular body, the floor of the orbit, maxilla, left parietal bone, the iliac bone and cervical and thoracal vertebras in a 36 years old female one and half years after operated.

Purpose: This study was undertaken with the null hypothesis that in patients, fully denate or with 1 or 2 teeth missing and older than 25 years, mastication does not affect late mandibular fracture after surgical removal of impacted third molars (M3s) associated with no gross pathology.

Materials And Methods: Five hundred sixty patients, fully dentate or with 1 or 2 teeth missing and older than 25 years who had no gross pathology associated with their impacted lower M3s, were recruited in this study. They were operated on under local anesthesia using a standard technique and randomly assigned into 2 groups for nonroutine (NR group) and routine (R group) postoperative instructions.

Objective: The objective of this study was to investigate the incidence and pattern of transmigrant maxillary canines.

Patients And Methods: The records of 6000 patients who were presented to our oral and maxillofacial surgery services between January 1998 and January 2007 were reviewed. Observations were made as to the right/left localization and number of transmigrant canines; sex and age of patients; retained deciduous canines; and any other associated pathology.

Cervical tuberculous lymphadenitis (scrofula) is an infectious granulomatous disease that requires a precise diagnosis. The differential diagnosis involves mainly the pathologic conditions involving the regional lymph nodes and the submandibulary salivary glands. Although tuberculous lesions generally develop secondary to pulmonary disease, clinical manifestations are occasionally seen with no evidence of involvement of the lungs.

This article investigates the anti-inflammatory effects of erythromycin (EM) on aseptic inflammation of temporomandibular joint (TMJ) space using by Tc-99 m HIG scintigraphy and histopathology. In this experimental study, 33 adult male New Zealand White rabbits were divided into three groups. The animals in the first group were treated with EM 25 mg kg(-1); the animals in the second group were treated with methylprednisolone (MP) 2 mg kg(-1) and the animals in the third group were given saline solution (control group).
