Clinical and CT scan findings were used to evaluate the accuracy of the reduction as well as the esthetic outcome secondary to the surgical approaches used. The patients were photographed according to a standardized protocol pre operatively and 3 months postoperatively. A blinded panel of reviewers was formed for assessment of the surgical results. The panel was composed of two groups . A specialized group which encompassed three oral and maxillofacial surgery consultants as well as two oral and maxillofacial radiology consultants. A second group encompassed three dental school students who volunteered to participate in the study. There were direct correlation between percent of satisfaction for surgeon, Radiologists and non-experts. Moreover, there were direct correlation between percent of satisfaction for Radiologists and non-experts using the Pearson correlation coefficient. Advocation of the Ellis and perez algorithm yields satisfactory esthetic outcomes.https://omx.journals.ekb.eg/article_19563_e6d4100afd618f3b0b2bfd66ab42459d.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X9220180401Management of fractures of anterior mandible with different fixation methods : A single institutional experience45541956410.21608/omx.2018.19564ENMahmoudKhalifaDepartment of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University, EgyptEmadEssaDepartment of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University, Egypt0000-0002-4131-5928MohammadElshallDepartment of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University, EgyptJournal Article20180427Aim: To evaluate the effectiveness of various internal fixation hardware used for treatment of symphyseal and parasymphyseal mandibular fractures based on a single institution`s experience.<br />Materials and Methods: In this retrospective clinical study, one hundred patients with fractures of the anterior region of the mandible involving both the symphysis and parasymphysis areas were included. All cases were selected from the patients` records who were treated in the oral and maxillofacial surgery department in a 4 years period extended from May 2013 to May 2017. Surgical admission notes, x-ray reports, operation records, outpatient notes, and complications were recorded. The patients were followed up periodically until a minimum of 6 weeks.<br />Results: The distribution of fracture pattern was as follows; 53 patients with anterior mandible associated with subcondylar/condylar fractures, 31 with anterior mandible in association with mandibular angle fractures, and only 16 patients with isolated anterior mandible fracture. The majority of the fractures (40%) were treated by 2 miniplates, followed by the 3-D miniplates (17%), equal use (12% each) of (2 lag screws, 1 lag plus 1 miniplate and 1 reconstruction plate), then 1 lag screw (4%), and the least was the use of only 1 miniplate (3%).<br />Conclusion: Proper selection of the fixation method for anterior mandibular fractures is essential to guarantee a successful treament and early restoration of function. Each method has its own advantages and disadvantages, and each case should be treated individually based on proper diagnosis and planning.https://omx.journals.ekb.eg/article_19564_d109156a9925e4dacf46e41f526e3c9b.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X9220180401Accuracy analysis between digital and clinical measurements of facial features55611956510.21608/omx.2018.19565ENAhmedSalehDepartment of Oral and Maxillofacial Surgery, Faculty of Dentistry, Ain-Shams University, Cairo, EgyptAmrGahnemDepartment of Oral and Maxillofacial Surgery, Faculty of Dentistry, Ain-Shams University, Cairo, EgyptMostafaTahaDepartment of Oral and Maxillofacial Surgery, Faculty of Dentistry, Ain-Shams University, Cairo, EgyptJournal Article20180519Introduction: Clinical facial analysis is essential for many specialists, such as plastic surgeons, maxillofacial surgeons, otorhinolaryngologists and other specialties. Clinical facial analysis is not a particular phase of clinical practice or a moment during a patient consultation. It is the largest part of a professional life and a never-ending process. Also obtaining accurate measurements is essential for achieving proper diagnosis, putting accurate treatment plans and following up the clinical outcome of the performed procedures. Obtaining accurate repeatable linear measurements clinically using a ruler between two different points on the face is always difficult, challenging and operator dependent because of different factors.<br />Material and Methods: This article presents novel technique to obtain accurate and repeatable measurements of linear facial measurements using standardized photos and computer software and compare the results with those obtained with clinically using a ruler.<br />Results: The inter observer reliability of the new technique was very reliable in comparison with traditional method. The reliability of the new technique was up to 1 while the clinical method was never up to this level of reliability.https://omx.journals.ekb.eg/article_19565_523712522705f1494fa75b61ed6ff45c.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X9220180401Evaluation of custom made xenogenic bone grafts in mandibular alveolar ridge augmentation versus particulate bone graft with titanium mesh62731956610.21608/omx.2018.19566ENMohammedAbuelnagaDepartment of Oral and Maxillofacial Surgery, Faculty of Oral and Dental Medicine, Cairo University, Cairo, Egypt.NaderElbokleDepartment of Oral and Maxillofacial Surgery, Faculty of Oral and Dental Medicine, Cairo University, Cairo, Egypt.MohammedKhashabaDepartment of Oral and Maxillofacial Surgery, Faculty of Oral and Dental Medicine, Cairo University, Cairo, Egypt.Journal Article20180628Aim: This study was to evaluate clinically and radiographically the volume changes of alveolar ridge grafting using customized xenogenic bone graft.<br />Materials and Methods: A total of 12 patients with mandibular horizontal and vertical alveolar ridge defects ≥ 3 mm were selected. They were divided into 2 groups: Group I (Test Group) included 6 patients in which mandibular alveolar ridges were reconstructed with customized Xenogenic bone graft Smartbone (IBI S.A., Switzerland). Group II (Control Group) included 6 patients in which mandibular alveolar ridges were reconstructed with particulate Xenogenic bone (Smart bone, IBI S.A., Switzerland) grafting to posterior mandibular ridge with titanium mesh was performed. Volume analysis of the changes in alveolar ridge in both Groups were obtained before and four months after the procedure using CBCT. Densitometric analysis of the Postoperative bone formed and compared with native bone. .<br />Results: Four months postoperatively. Measurements made on cone-beam computerized tomograms, four months postoperative showed significance increase in bone volume by 40 % in the area of newly formed bone in Group I (Customized bone) compared with 23% in Control Group. Statistical significant changes was found in the density of newly formed bone four months post-operatively in both Groups, however there was no significant difference in bone density postoperatively between Group I (customized Bone) and Group II (Control).<br />Conclusion: According to the results, the treatment of defective alveolar ridge augmentation of the mandibular ridge with customized xenogenic bone graft Smartbone (IBI S.A., Switzerland) is successful and produces results consistent with the control Group.https://omx.journals.ekb.eg/article_19566_b38910574bf1f4047155fe512ce77f46.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X9220180401Enhancing bone healing in calvarial critical size defect using ozone gel : Histological and histomorphometric analysis74831956710.21608/omx.2018.19567ENMohamedElsholkamyAssistant Professor of Oral and Maxillofacial Surgery, Faculty of Dentistry, Suez Canal University, Ismailia, Egypt.MaggieKhairyAssistant Professor of Oral and Maxillofacial Surgery, Faculty of Dentistry, October 6 University, Cairo, Egypt.TamerNasrLecturer of Oral and Maxillofacial Surgery, Faculty of Dentistry, Misr International University, Cairo, Egypt.Journal Article20180619Aim: The aim of this study was to examine the validity of the hypothesis that Ozone gel will accelerate bone healing in a critical size defect model experimentally created in rabbit calvaria when mixed with autografts in comparison to autogenous grafts per se.<br />Materials and Methods: A total of twelve adult male New Zealand Rabbits were included in the study. A total of 24 standardized bone grafts were harvested from 12 animals after critical size defects were created in calvaria cortical bone, each graft was crushed using a special bone mill device. After bone milling, each bone graft was collected in a special sterile container, twelve grafts were mixed with normal saline solution (control group) and each one of the rest of the grafts was mixed with ozone gel. Animals were sacrificed at 4 and 8 weeks’ post-surgery, dual energy x-ray absorptiometry (DEXA) scans were performed for the skull of the rabbits and bone specimens were collected for histological examination.<br />Results: Histomorphometric analysis showed superior results in favor of the ozone treated group represented as a significantly higher percentage of normal osteocytes and marked increase in area percentage of new bone formation. Additionally, DEXA scan revealed a significant increase in bone mineral density and bone mineral concentration of the ozone treated group compared to the control group.<br />Conclusion: The authors believe that according to the available results the use of ozone gel may be cost effective and convenient owing to its ease of preparation. It is recommended to be used with routine bone grafting procedures as it accelerates the new bone formation over time giving higher degree of overall maturation and strength.https://omx.journals.ekb.eg/article_19567_f8417d6b6c765d117fe86b9ab9de3aaa.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X9220180401Assessment of low level diode laser therapy versus arthrocentesis in management of temporomandibular joint internal derangement84921956810.21608/omx.2018.19568ENAdullahHammudaDepartment of Oral and Maxillofacial Surgery, Faculty of Dentistry, Minia University, Minia, EgyptJournal Article20180723Introduction: Many nonsurgical therapies have been suggested for the management of Disc derangement disorders such as physical therapy, pharmacologic therapy, through psychological counselling, cognitive behavioural therapy, occlusal splints and acupuncture. Among physical therapy procedures, low level laser therapy (LLLT) has recently been proposed to reduce symptoms and improve function in TMD patients.<br />Aim: The aim of this study is to evaluate effectiveness of Low level diode laser therapy as a treatment modality in temporomandibular joint internal derangement.<br />Patients/Methods: Thirty six patients presented with jaw pain, clicking and limited mouth openings were involved in this study. Clinical, radiographic and magnetic resonance imaging (MRI) were performed to exclude muscular, hyperplastic or degenerative causes. They were divided randomly into two groups. group I, subjected to arthrocentesis and group II, subjected to ten sessions of LLLT on fixed predetermined points.<br />Results: Statistical analysis has shown a significant improvement in both groups after six month regarding Pain, range of mandibular movements and clicking.
