Background: Particulate autogenous bone grafts remain to be the gold standard for reconstruction of alveolar. The success of alveolar bone grafting is assessed clinically and radiographically. Among the radiographic measures of success is the bone bridging across the cleft, maintenance of the bucco-palatal / vertical linear dimensions of the graft and the stability of the total volume of regenerated bridge of bone. Computed tomography (CT) scans provide a better tool for three-dimensional evaluation of the residual bone following the reconstruction procedure.Aim of the study: This study aimed at assessing the linear (horizontal, vertical) and volumetric changes that occur in particulate iliac bone grafts 6 months after secondary grafting of unilateral alveolar clefts.Patients and Methods: Six patients with unilateral alveolar clefts who received particulate autogenous iliac crest grafts were included in this study. On a surgical planning software, their immediate and six-months postoperative CT scans were superimposed onto each other using the cranial base as a reference. On the axial cuts, the linear bucco-palatal dimensions of the reconstructed alveolar cleft were recorded, whereas on the coronal cuts the vertical height of the reconstructed alveolar cleft was measured for both scans. The software was also used to calculate the volume of the bone graft on the immediate postoperative CT and that of the remaining bone graft 6 months after. The data was statistically analyzed in the form of means ± standard deviation and paired T-test used to compare the measurements immediately and six-months postoperatively. The percentage change in the alveolar ridge dimensions over the six months follow up period was then calculated.Results: The horizontal dimension of the grafted alveolar cleft decreased by an average of 24.4% over the six months period. The difference between the means showed a highly statistically significant difference with a P value < 0.01. While for the vertical dimension, the mean decreased by 21.6% over the six months period and the difference between the means was statistically significant with a P value Conclusions: Radiographic assessment of alveolar cleft reconstruction using CT scans are useful tools, not just for making accurate measurements and better evaluation of the formed bone within the reconstructed alveolar cleft, but also it provides a useful tool for analyzing the outcomes of the secondary alveolar grafting procedure for future correlation and optimization of the whole grafting procedure and expected outcomes.

The aim of this study is to evaluating the effectiveness of use of Michigan splint in the management of Temporomandibular joint disorders (TMD) in comparison to superior repositioning splint (SRS) as a control group in a one-year follow-up.. Material and methods: Sample was initially constituted by 40 patients, randomly divided into two groups: I- Michigan splints, II- Superior repositioning splints. The whole sample was evaluated by means of TMJ and muscle palpation, mandibular range of motion (ROM), analysis of occlusal contacts, joint sounds inspection and Visual Analogue Scale (VAS) for one year. Results: A significant (after 15 days) improvement in pain report (VAS) and palpation index was found for group II (p²0.01). The occurrence of occlusal alterations as posterior open bite or gross interferences after the splint therapy and increased muscle tenderness were not problems in this study. Similar results in joint noises reduction were observed for the entire sample. Conclusion: It was concluded that use of repositioning splints is a beneficial tool in the management of intra-articular pain and dysfunction, with no risks of irreversible occlusal changes.

Biomechanical evaluation of three dimensional titanium miniplates in mandibular fracture fixation
Abdelmageed
Alfakhrany
Atef
Hasanein
The unique position of mandible on the face makes it one of the most commonly fractured facial bones and considered the most common fractures treated by oral and maxillofacial surgeon.There are a number of methods used till date for the treatment of mandibular fractures. Traditionally, the treatment modalities have ranged from conservative measures such as maxillomandibular fixation by means of wiring, splints or arch bar fixation to open reduction with fixation. Most authorities today, advise open reduction and fixation by plates and screws which is necessary for most of the mandibular fractures. This study was conducted to evaluate an in vitro biomechanical properties of 3 dimentional plates used for treatment of mandibular fracture treatmen t(fixation). For this purpose a 20 sheep mandible was used to make the biomechanical tests (compression-tensile –torsional) on the universal testing machine.In the present study, the results of the mean yield compression and tension stresses revealed that the used fixation system proofed to be highly efficient for supporting the fracture In during the period of osteosynthesis, as their point of deformation under load is far away from the reported maximum forces suitable for normal osteosynthesis processes . Three dimensional miniplates are easy to adjust, requires minimal tissue dissection thus least disturbance to the tissues. Its low profile design and space between plate holes permits excellent revascularization. Comparing the three dimensional plating system with conventional systems, only fewer plates and screws are needed to stabilize the bone fragments.

Body ostectomy for correction of severe mandibular excess using piezosurgery
Mohamed
Osman
Moataz
Elshehaby
Prognathic mandible affects the patient’s appearance and profile. Many techniques have been advocated for the surgical correction of mandibular excess and improving aesthetic and functional results. This study was conducted to investigate the efficacy of body ostectomy for severe mandibular excess by using piezosurgery. The study consisted of nine patients. They had cosmetic and psychosocial hindrance related to mandibular excess. In the cephalometric analysis, severe mandibular excess (≥8mm reverse overjet) were selected. All patients underwent mandibular body ostectomy using piezosurgery. Clinical evaluation was made postoperatively. The average time of operation was 3.5 h with mean blood loss of around 300 ml. The postoperative course was uneventful. Generalized patient satisfactions were recorded. An acceptable occlusion was developed. The patients’ facial esthetics were improved. Mandibular body ostectomy provides satisfactory outcomes (esthetic and functional) in cases of severe mandibular excess especially with intact posterior occlusion. Ultrasonic bone surgery could spare adjacent soft tissue and neurovascular bundle and hence reduce trauma, bleeding and enhance visibility. The surgical procedure duration is longer with the application of piezosurgery.

Purpose: Myofascial pain dysfunction syndrome (MPDs) coupled by trigger points (TPs) has been conversed medically and dentally for over a century. Phonophoresis (PH) is a non-invasive transdermal drug delivery system that use ultrasound (US) to enhance the distribution of topically applied drugs which provide less chance of an overdose and permit both local and systemic treatment effects. The aim: of this study was to assess the outcome of phonophoresis with Extrauma and ultrasound therapies in the treatment of myofascial pain dysfunction syndrome. Patients and method: twenty cases with MPDs of TPs in the masseter muscle were selected and divided into two groups; study group (PH): comprised ten female patients that were treated with phonophoresis (PH) using Extrauma gel for 10 sessions over three weeks. Control group (US): comprised ten female patients that were treated with ultrasound (US) for 10 sessions over three weeks. Postoperative clinical assessment including visual analogue scale (VAS) and maximum mouth opening (MMO) were assessed. Results: Comparison of VAS between the two groups at immediate post-operative period showed that PH group recorded decrease and significant values and at six months post-operative period the two groups showed non-significant decrease in VAS. MMO showed non-significant increase values in both groups along the follow up periods. Conclusion: Extrauma phonophoresis in the masseter muscle trigger points considered an effective treatment option for myofascial pain dysfunction syndrome.

Purpose: The aim of the present study was to evaluate synergistic osteogenic potential of human dental pulp mesenchymalstem cells (hDMSCs) and platelet-rich plasma (PRP) in enhancement of bone regeneration in anterior maxillary bone defects.Patients and methods: Eighteen patients (10 males and 8 females), were selected and divided equally into three groups. Group I included patients (4 male and 2 female ) having anterior maxillary cyst and impacted or supernumerary teeth in another place indicated for surgical removal for production of mesenchymal dental pulp stem cells, group II and III included patients (3 male and 3 female in each) having anterior maxillary cyst. The cyst was enucleated and the space left were filled by hDMSCs with PRP in group I. in group II the cavity was filled by PRP only. In group III the cystic cavity left with no filling material and considered as control group. Cone Beam Computed Tomography (CBCT) was performed preoperatively, one month and six months postoperatively for comparison of bone density intra group and inter groups. Results: Comparison of bone density between the three groups at one month post-operative period showed that group II recorded highest and significant bone density. At six months post-operative period the three groups showed significant increase in bone density However group I (hDMSCs with PRP) showed highest mean increase in bone density. Conclusions: hDMSCs can provide an osteogenic cell source for new bone formation and the PRP improves and retains their differentiation capacity due to possible synergisticosteogenic potential between PRP and stem cells.

Retaining of the medially displaced condyle and disc in the surgical treatment of type III temporomandibular joint ankylosis
Ahmed
Naguib
Purpose: To evaluate the effectiveness of retaining of the medially displaced condyle and disc in the surgical treatment of type III temporomandibular joint ankylosis. Patients and methods: Eight patients with type III temporomandibular joint ankylosis, according to Sawhney(6) classification were included in this study. 5 males and 3 females, their ages in between 12 to 42 years with a mean of 33 years. All the patients were evaluated preoperatively both clinically (determination of maximal inter-incisal opening in mm, assessment of mandibular deviation, presence of pain on the affected joint, examination of occlusion and examination of function of the facial nerve) and radiographically (using axial, coronal and three dimensional computerized tomograms) to determine the presence of ankylosis on the lateral aspect of the TMJ and to determine the presence of medially displaced condyle. All the clinical and radiographic parameters were performed immediately, 3 months, 6 months and finally one year after surgery.Results: Regarding to the maximal inter-incisal opening, there was improvement in mouth opening, as the mean of inter-incisal distance preoperatively was 6mm and increased after one year postoperatively to 35 mm. The visual analogue pain scale (VAS) revealed no pain after one year, from surgery in all patients. All patients showed presence of proper postoperative occlusion according with no occlusal disturbances nor presence of deviation in mouth opening toward the affected side, as the condyle was preserved and height of the ramus of the affected side was maintained during the follow up periods. No permanent damage to the facial nerve had been detected in any case. Radiographic evaluation revealed proper remolding of the reconstructed joint, no evidence of bony overgrowth no recurrence of ankylosis in all operated joints and the medially displaced condyle articulates properly with the base of the skull, medial to the glenoid fossa. Conclusion: Retaining of the medially displaced condyle and disc during surgical treatment of type III TMJ ankylosis seems to be safe and efficient method as:- 1) The bony resection was far easier than conventional methods, as all work was carried out on lateral side of the joint. 2) There was less chance of bleeding and so, the surgery was relatively safe. 3) Preservation of the disc makes no need to use any interpositional material. 4) Preservation of the condyle leads to maintaining the ramus height and also the retained condyle can fulfilsits role in mandibular growth and function. 5) There is no need to reconstruct the joint with autogenous or alloplastic material.

Aboelsaad
Background: Bone augmentation of narrow residual alveolar ridges in anterior maxilla is mandatory for better esthetical results. Many attempts were done to achieve acceptable outcomes including bone expansion. Using screw-type expanders is an acceptable treatment modality, complication-free and less sensitive technique. With the increase of esthetic demands, it was the importance of implant’s early loading which depends on its modified surface. The aim of this study was to evaluate clinically and radiographically the efficiency of placing Trabecular Metal Material implants with bone expansion in narrow anterior maxilla.Materials and Methods: For this clinical trial, 20 patients requiring implant placement in the narrow anterior maxilla of sufficient bone height and of ridge width ≥ 3mm but < 6mm were selected. Bone expansion using screw-type expanders was performed with simultaneous placement of Trabecular Metal Material implants. The studied variables were the degree of facial swelling, marginal bone height and bone width. The follow-up period was six months. For statistical analysis, Friedman and Wilcoxon tests were used.Results: A Significant decrease regarding marginal bone height and a significant increase regarding bone width were observed through the follow-up stage, while no significant difference was noticed concerning the degree of facial swelling when compared to base line measurements.Conclusion: The results assured the efficiency of bone expansion using screw-type expanders with simultaneous placement of Trabecular Metal Material implant and highlighted their promising effects concerning esthetical considerations.

Influence of Aragonite Calcium Carbonate on Bone around implants loaded with Mandibular Zirconia Telescopic Overdenture: A CBCT Radiographic Comparative Study
Mahmoud
Salloum
Hashem
Hassouna
Implant overdenture treatment is a popular line of treatment in edentulous patients where a hybrid implant-supported bridge is unsuitable. Telescopic attachment is considered one of the successful type of attachment used in overdenture patients. This study is conducted to clarify the value of using Calcium Carbonate graft material to enhance osseointegration and peri-implant bone. Zirconia was used as telescope material prepared by CAD CAM technology to maximize quality of attachment used. Ten completely edentulous male patients were selected according to predetermined criteria to receive twenty root-form endosseous implants (Protem/secure implant systemDio implant Dio corporation 1464, U-dong Haeundae-gu Busan, Korea) at the mandibular canine areas. As a within subject study, implants were categorized into two groups, graft material received group and control group. Overdentures were constructed after incorporating the telescopic attachment and finally the peri-implant bone was monitored using cone-beam CT (CBCT) at loading time, after 3, 6, and 12 months to measure the amount of marginal bone height loss and quality change around each implant. The results showed improvement in both peri-implant bone height and quality. Accordingly, within the limitation of the present study, the use of Calcium Carbonate graft material is an effective measure to enhance and stabilize peri-implant bone in implant overdenture patients.

Bone marrow aspirate versus two bone autograft types in reconstruction of alveolar cleft: A histomorphometric analysis
Hassan
Abdelghany
Hesham
Fattouh
Objectives: The aim of this study was to compare histomorphometrically between bone marrow aspirate on a collagen carrier with autogenous bone grafts harvested from two different donor sites in alveolar cleft defect repair.Materials and Methods: eighteen patients with alveoalar cleft defect were included in the study. Twelve out of eighteen patients were reconstructed with auotogenous bone graft; six patients grafted with illium bone graft and six patients grafted with chin bone graft. The remaining patients out of eighteen were reconstructed using bone marrow aspirate implanted on a collagen carrier. Six months after grafting, bone specimens from augmented alveolar ridge sites were retrieved by trephine burs for histomorphometric analysis. Results: Good consolidation of the grafts have been observed, this was demonstrated by intense osteogenesis indicating an active remodeling process. In all groups, the improvement in bone quality of the receptor site was clear with no statistical significance between the groups, however, the autografts presented better bone quality.Conclusions: From this study it was possible to conclude that quality of bone repair using autogenous bone graft is superior to bone marrow aspirate. The time needed for bone maturation is less when chin or iliac autogenous grafts have been used in comparison to the bone marrow aspirate.

Ayman
Abdel-wahab
Purpose: Lymph node metastasis has an important influence on patient survival after oral cancer. This study aimed to evaluate the incidence of metastasis to Sublevel IIb lymph nodes in patients with squamous cell carcinoma of the oral cavity. Materials and methods: Thirty patients with Oral Cavity Squamous Cell Carcinoma (SCC) were included in this study. They were selected from the out-patient clinic in the National Cancer Institute, Cairo University. All cases were subjected to surgical resection of the primary site with safety margin according to the standard protocol for each specific site. Functional neck dissection (ND) for neck lymph nodes and dissection for sublevel IIb lymph nodes were preformed separately. Histopathological examination of the specimens of the primary tumor sites, the neck lymph nodes and the level IIb lymph nodes was performed separately.Results: In all thirty neck dissections, examination of the level IIb provided a negative result, except in only one case (3.3%). This case was SCC of the tongue. The metastasis at sublevel IIb in this case was observed without metastasis at levels IIa, III or IV. Neck Lymph node metastasis was found in 53.3% of the patients who underwent therapeutic neck dissection for oral SCC. Conclusions: Based on our study we concluded that metastatic spread of oral cavity SCC to level IIb in cases of clinically positive neck (cN+) is rare.

This study dealt with a case of rare hybrid odontogenic tumor involving a combination of the aggressive clear cell odontogenic carcinoma (CCOC) and the benign granular ameloblastoma (GA) and its computer guided resection and reconstruction.Patients and methods: A 79 years old male, was referred to the oral and maxillofacial surgery department at the Faculty of Dentistry, Cairo University with a progressively facial swelling at the anterior mandible with palpable and tender submandibular lymph nodes (LN). He had a difficulty in breathing and inability to wear his removable denture. An intra-oral ulceration over the tumor was evident. Radiographic findings revealed a well-defined, multilocular lesion of 60 x 56 mm of size. Surgical resection of the lesion with safety free margins using computer guided 3D printed seating device used as an osteotomy guide with a stabilizing arm to prevent disarticulation of the condyles and collapse of the ramus of both sides. Immediate reconstruction plate and fibula vascularized flap were used.Results: The excised lesion was sent to the pathology lab for microscopic examination. The specimen revealed a dominating clear cell carcinoma with minor granular ameloblastic appearance. The final diagnosis reached was a Hybrid odontogenic tumor.Conclusion: Our study uncovered the presence of a rare hybrid tumor of the CCOC and granular ameloblastoma. Wide resection with safe margin is the only documented line of treatment due to its highly aggressive malignant nature with subsequent composite fibula free flap reconstruction.The use of computer guided 3D printed devices is always beneficial. In this case, it was used as an osteotomy guide and to hold the mandible intra-operatively to prevent its collapse during tumor removal and before mandibular fixation.
