Patients will be divided randomly in to two groups of 10 patients. Group A will be scheduled for ridge augmentation<br />using Kazanjian vestibuloplasty incision approach and group B will be scheduled for ridge augmentation using crystal incision.<br />Results: This study demonstrated that the use of Kazanjian vestibuloplasty resulted in significant increases in ridge width and<br />height. In group A the amount of bone height gained was 2.25 ± 1.31 mm (P < 0.001) and bone width gain was 2.3 ± 1.49<br />mm (P < 0.002), while in group B the amount of bone height gained was 0.75 ± 0.97 mm (P < 0.001) and bone width gain<br />was 0.45 ± 0.55 mm (P < 0.002).<br />Conclusion: In posterior mandible reconstruction, bone grafts increase the number, length, and diameter of implants that can<br />be placed. The use of Kazanjian vestibuloplasty is better than crestal incision as an approach during ridge augmentationn using<br />Nanobone block.<br />Recommendation: More attention to detail and meticulous technique may prevent the progression of complications to Nanbone<br />block graft failures.https://omx.journals.ekb.eg/article_226648_83bca5372e7f8e8a8f5121d43834f9df.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401Long term effects of double charged hemihypoglossal-Facial Nerve Neurorrhaphy on the histological structure of orbicularis oculi muscle859422665310.21608/omx.2021.65350.1114ENKhaledBarakatDepartment of Oral and Maxillofacial Surgery Faculty of Dentistry Minia University0000-0002-5700-346XMohamedRabeaDepartment of Oral and Maxillofacial Surgery Faculty of Dentistry Minia UniversityDaliaEl WaseefDepartment of Histology and Cell Biology Faculty of Midicine Ain Shams UniversityHamedGadDepartment of Oral and Maxillofacial Surgery Faculty of Dentistry Minia UniversityJournal Article20200302Objective: to assess the effect of Hemi Hypoglossal-Facial nerve neurorrhaphy (HHFN) with double charge "supercharge"<br />technique on the structure of orbicularis oculi muscle (OOM) fibers in goats.<br />Material and method: The current research was carried on six goats where the right side acted as experimental while the left<br />acted as control without any intervention. The right Facial nerve (FN) was intentionally transected and immediately repaired<br />using an ipsilateral end to end hemi hypoglossal nerve<br />(HHN) neurorrhaphy to the distal facial trunk and end to side to its proximal end "supercharge". One year later animals were<br />anaesthetized and samples were bilaterally harvested from (OOM). Both groups were histologically and clinically assessed and<br />compared.<br />Results: Double charged neurorrhaphy technique revealed the preservation of the normal histological pattern of muscle fiber,<br />arrangement, shape and diameter. However, collagen fibers were significantly increased around the muscle fibers (P < 0.05). On<br />the other hand, the nuclei retained their normal number and sites.<br />Conclusion: HHFN with supercharge histologically preserved the structure of the OOM fibers reflecting the excellent clinical<br />outcome of the technique.https://omx.journals.ekb.eg/article_226653_aa0399cd75064ecf13f201a2400c3eb4.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401Comparative study between two different surgical techniques in veloplasty9510422665710.21608/omx.2022.82559.1122ENElsaadanyWesamDepartment of Oral and Maxillofacial,

No oronasal fistula was recorded in any case in the two groups. By magnetic resonance imaging, there<br />was effectiveness in palatal reconstruction and future imoprovement of soft palate function which reported from a significant<br />increase in soft palate length postoperatively in both groups with no significant differences between them, a significant decrease<br />in retropalatal ditance postoperatively in both groups with no significant differences between them and the cohesive sling<br />created by the two levator muscle bundles postoperatively in both groups.<br />Conclusion: There was no statistically significant differences clinically and by magnetic resonance imaging between intravelar<br />veloplasty and Furlow double opposing z-plasty technique.https://omx.journals.ekb.eg/article_226657_b10c08284349a21bbd288fbaa4ecaa7c.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401Dental Interns and Students Self-Confidence toward Oral Surgery Clinical Procedures10510922666010.21608/omx.2021.86330.1126ENSherinAlhalawanyaMinistry of HealthThakibAlshalanbCollege of Dentistry, King Saud University, Riyadh, Saudi ArabiaJournal Article20210714Background: Dental colleges in the world have different missions and the dental curriculum varies between dental colleges.<br />Oral surgery is an important clinical specialty in the dental curriculum. As the curriculums vary, the oral surgery teaching and<br />clinical trainings also vary. Due to these variations, it is important to highlight the findings of previous studies that investigated<br />the teaching and education of oral surgery.<br />Aim: The aim of the study is to summarize the perception of dental interns and students toward oral surgery learning outcomes.<br />Materials and Methods: In this brief review, a summary of the review of selective previous publications is presented. Medline<br />and Google were used as the search engine for the previously published articles.<br />Results: The previous studies showed variations in the confidence level of dental undergraduate students toward different<br />oral surgical procedures. Dental interns and students have higher level of self-confidence in performing simple extraction<br />procedures. Other clinical procedures such as surgical extraction, biopsy, and flaps were not perceived well by interns and<br />students.<br />Conclusion: This review showed that dental students and interns have basic knowledge and clinical oral surgery procedures. It<br />is recommended that dental colleges make every possible effort to update the oral surgery didactic and clinical components of<br />the oral surgery courses for undergraduate studentshttps://omx.journals.ekb.eg/article_226660_85eb27125aee6833397d8eef9c6c2597.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401The diagnostic efficacy of multiplanar and 3-dimensional MDCT in Evaluation of Traumatic Maxillofacial Injuries11012022666210.21608/omx.2021.86992.1127ENJoyShakeraaDepartment of Diagnostic and Interventional Radiology, Department of

The detected fractures were documented<br />and tabulated into three groups. The first group the data obtained in axial images, the second group the data obtained in multiplanar<br />reformatted images, and the third group 3D-reconstructed images.<br />Results: Orbital, mandibular, and maxillary fractures were the most frequent fractures occurring in 37 (50.6 %), 37 (50.6 %),<br />and 33 (45.2 %) cases respectively. 3D reconstructed images had the highest sensitivity in diagnosing the infraorbital fractures<br />compared with axial, sagittal, and coronal reformatted images (p ꞊ 0.00, p ꞊ 0.03 and p ꞊ 0.01 respectively). Coronal reformatted<br />images performed better than axial images in the evaluation of pterygoid plate fractures, and axial images were better in the<br />case of anterior maxillary wall fractures in comparison to 3D reconstruction (p ꞊ 0.01). Sagittal reformatted images had the least<br />sensitivity in diagnosing mandibular fracture and condylar dislocation.<br />Conclusion:Multiplanar reconstruction increases the effectiveness of visualization of facial fractures.3D images provides<br />better visualization of fracture lines and displaced bony fragments especially in the case of Le Fort fractures.https://omx.journals.ekb.eg/article_226662_a1e11e481bf05a90482331b6401161f5.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401Comparative Study of Orbital Volume Reconstruction Using Stereolithographic Model Versus Free Hand Orbital Titanium Meshworks in Unilateral Orbital Floor Fracture: (A retrospective study)12112722666410.21608/omx.2021.74145.1119ENAhmedSalahDepartment of Oral and Maxillofacial Surgery, aAhmed Maher Teaching Hospital,Cairo, EgyptAmanyEl SayedbFaculty of Dentistry, Modern University for Technology and Information,
Cairo, EgyptJournal Article20210426Background: Orbital blow out fracture can alter cavity dimensions and position of intra-orbital contents. Anatomical reduction<br />and reconstruction of the orbital fracture is important for preventing latter complications. Introduction of medical software for<br />virtual surgical planning and printing of stereolithographic (STL) models, allows the clinician to pre-bent the titanium orbital<br />meshwork preoperatively reproducing accurate osseous anatomy. This reduces the risk of free hand orbital meshwork (FOM)<br />malposition, poor anatomical contour and trauma to soft tissues.<br />Aim of the study: The aim of this study was to compare the orbital volume when using (STL) model versus (FOM) in the<br />treatment of patients with unilateral orbital floor fracture.<br />Materials and Methods: Sixteen patients were included in this study. Chief complaint was orbital facial asymmetry related<br />to an accident. Patients were divided into two groups, eight patients in each group. Group I was treated via (STL) model and<br />group II with (FOM). Orbital volume ratio (OVR) then differential volumetric percentage were calculated for both groups.<br />P value < 0.05 was considered significance.<br />Results: Measurements of orbital volume comparing the repaired side to the normal side; of group I revealed non-significant<br />difference, while in group II revealed significant difference. Measurements of orbital volume comparing group I and group II<br />revealed significant difference.<br />Conclusion: The application of (STL) technology in a unilateral orbital cavity reconstruction gives a good understanding of the<br />anatomical state of the injured orbit.https://omx.journals.ekb.eg/article_226664_ac05573cbb6cda3c4f547a084e7bd804.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401Post extraction immediate implant placement in infected extraction sockets of maxillary posterior teeth combined with guided bone regeneration.

EgyptJournal Article20210902Aim: This study aimed to evaluate clinical and radiographic outcomes of immediate implant placement in infected extraction<br />sockets of maxillary posterior teeth (presented with buccal fenestrations) combined with guided bone regeneration.<br />Materials and Methods: Eight patients with non-restorable maxillary posterior teeth that needed to be extracted due to failure<br />of endodontic treatment or badly destructed teeth presented with periapical lesions and buccal fenestrations were included for<br />this study. Implants were immediately inserted in extraction sockets after adequate debridement, curettage, and irrigation,then<br />the gap between the implants and sockets were filled with bone graft and guided bone regeneration.Clinical (plaque scores,<br />gingival scores, probing depth, and width of keratinized mucosa) and radiographic (crestal bone loss) outcomes were evaluated<br />at baseline (prosthesis insertion), 6, 12 and 24 months later.<br />Results: A total of 21 implants were placed in 8 patients.Three implants failed resulting in 95 % cumulative survival rate<br />after 24 months. Plaque scores significantly increased from prosthesis insertion to 6 months then significantly increased from<br />six months to 12 months.Gingival scores increased significantly from baseline to 6 months, then decreased significantly at<br />12 months. Pocket depth increased from prosthesis insertion to 6 months, then significantly decreased from 12 months to 24<br />months. No significant difference in keratinized mucosal width between different time intervals. Crestal bone loss significantly<br />increased from 6 months to12 months, then significantly increased from 12 months to 24 months.<br />Conclusion: Within the scope of this investigation, post extraction immediate implant insertion in infected sockets of maxillary<br />posterior teeth presented with bone defects or buccal fenestrations and bone augmentation is a safe and predictable method as<br />implants demonstrated good clinical and radiographic outcomes after 2 years.https://omx.journals.ekb.eg/article_226666_744f5dbd64671451c8c5547375e00b4e.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401Effect of smoking on immediate loaded implants placed by flapless computer guided surgery to support full arch fixed restoration inedentulous maxilla.

The control group < br />comprised of 5 participants who had not smoke for at least 5 years and were case matched to study group. All patients received<br />6 implants in the maxillary ridge using computer guided surgery and flapless surgical protocol and the implants were immediately<br />loaded with fixed acrylic bridge.6months later, final ceramo-metal screw-retained prosthesis was delivered. Clinical (plaque<br />scores, gingival scores, pocket depth, implant stability,width of keratinized mucosa) and radiographic outcomes (crestal bone<br />loss) were measured at implant loading, 6 and 12 months later.<br />Results: Implant survival rate was 93.3 % and 80 % for non-smoker and smoker groups with significant difference between<br />groups. At 6 and 12 months, smoker group recorded significant higher plaque and gingival scores, pocket depth, and crestal bone<br />loss than non-smoker groups. At 6 months only, smoker group recorded significant higher implant stability than non-smoker<br />groups, however the difference disappeared after 12 months. No difference in width of keratinized mucosa was observed<br />between groups.<br />Conclusion:Within the limits of this study, smoker patients were associated with worsen clinical and radiographic outcomes<br />of immediate loaded implants placed by flapless computer guided surgery to support full arch fixed restoration in edentulous<br />maxilla compared to non-smoker patients.https://omx.journals.ekb.eg/article_226668_e3f6136c56bbdc167455c230bc44146f.pdfThe Egyptian Association of Oral and Maxillofacial SurgeonsEgyptian Journal of Oral and Maxillofacial Surgery2090-097X12220210401Xenograft Versus Graftless Crestal Sinus Lift with Simultaneous Implant Placement14915722667110.21608/omx.2021.93740.1134ENSallyAbdelsameaaDepartment of Oral Surgery, ,Faculty of Dentistry,Mansoura University, Mansoura, Egypt0000-0002-7454-9560FakhreldinAbdel-RahmanDepartment of Oral Surgery, Faculty of Dentistry,

The<br />average age was 38 years (ranged from 21 to 55 years). The patients were randomly divided into two groups. In the first group,<br />patients underwent crestal sinus floor elevation with simultaneous implant placement using graftless technique, while in the<br />second group, patient underwent crestal sinus floor elevation with simultaneous implant placement using xenograft. Patients<br />were evaluated clinically and radiographically at regular time intervals immediately, 3 months and 9 months after surgery. All<br />clinical and radiographic parameters were subjected to statistical analysis.<br />Results: Fourteen implants were stable. There was no significant difference in implant stability between group I<br />(64.14 ± 3.13, 70.43 ± 3.95, 78.0 ± 2.71) and group II (67.57 ± 5.06, 73.43 ± 4.31, 79.86 ± 2.91) through the whole study<br />period, while there was significant difference in bone height gain between group I (4.60 ± 0.95) and group II (6.16 ± 0.49)<br />after 9 months (P = 0.002).<br />Conclusions: This study confirms the validity of graftless sinus lifting procedure when simultaneous implant placement<br />is performed.https://omx.journals.ekb.eg/article_226671_5f86c546dc69645cda53c9f61bfb4bb1.pdf
