Purpose: The aim of this study is to evaluate oroantral communication (OAC) repair using one bone substitute (Fisiograft) and platelets rich fibrin (PRF). Patients and methods: In the present study, eight patients complaining from OAC following extraction of maxillary posterior tooth were selected. The bony defect of the OAC was grafted with Fisiograft sandwiched between two PRF membranes. Then the graft was covered by buccal advancement flap. The patients were followed up clinically after 1, 2, 4 and 12 weeks postoperatively. Radiographic evaluation was performed immediately and after twelve weeks postoperatively. Results: Successful closure of the OAC was achieved in all cases. None of the cases reported recurrence of the OAC or regurgitation of fluids from the nose. There were no signs of dehiscence, infection, allergic reaction, ulceration, or exposure of the material. The covering mucosa returned to the normal color and texture by the end of the first month. Radiographically, the bony defect appeared radiolucent immediate postoperatively. After three months, there was almost complete healing of the bony defect of the OAC. Densitometric measurements showed statistically significant increase in the bone density at the defect area after three months postoperatively. Linear measurements showed no statistically significant vertical loss of alveolar bone after three months postoperatively.

Objective: The purpose of this study was to evaluate both clinically and radiographically using of two microplates in treatment of displaced pediatric mandibular fractures.Materials & methods: This study included ten children had displaced mandibular fracture with age ranged between (4e11) years were treated using two microplates and microscrews through intraoral approach. All children were examined preoperative clinically and radiographically by panoramic view and computed tomography (CT) or lower occlusal view. All children were evaluated postoperative clinically at one week, one and three months for wound healing, occlusion, infection, nerve affection and stability of fracture and radiographically by panoramic view at second postoperative day, one and three months and by quantitative CT at one and three months to evaluate the accuracy of reduction and bone healing at fracture line. Results: Clinically there were no complications in all cases overall follow up period except for two cases showing occlusal discrepancy treated with guiding elastics. Radiographic results showed that good alignment of fracture segments horizontally and vertically without displacement and significant increase in bone mineral density gain after one and three months. Conclusion: Titanium microplates provide adequate stability for fracture segments in treatment of pediatric mandibular fracture. Low profile and malleability of microplates allow adaptation to mandible easily and minimize the possibility of trauma to teeth buds.

Purpose: This study was planned to evaluate, both clinically and radiologically, the efficacy of using ultrasound based welding process by (Sonic weld Rx) for fixation of biodegradableplates in pediatric mandibular fractures. Patients and methods: This study comprised 8 patients, theirages ranged from (2) to (10) years with mandibular fractures treated with open reduction and internal fixation using poly-D and L-lactic acid (PDLLA) plates by SonicWeld Rx through an intra-oral approach.Preopertivelly patients were examined clinically by inspection and palpation both extraorally and intraorally. Radiographic examination via orthopantomograph and computed tomography (CT).Postopertivelly patients were evaluated clinically immediately, at two weeks, and at one, three and six months. Radiographically by Panoramic radiographs immediately and at one, three and six months and Quantitative computed tomography (CT) after one and three months. Results: The results revealed primary wound healing in six patients with no signs of infection or dehiscence and two patients exhibited scaring in the repaired wound, proper occlusion, postopertively except one patient had minor occlusal discrepancies corrected by elastics and all cases showed stability of the fractured segments.Radiographic examination for all patients at the different follow up periods statistically revealed significant bone healing. Conclusion: We can conclude that Ultrasound based welding process by (Sonic weld Rx) for fixation of PLDLA plates and pins was effective in pediatric mandibular fractures.

Tibial fractures are the most common fracture of long bones. These wounds result from highvitality injury, for example, tumble from tallness and vehicle accidents.Management of distal tibia breaks, with or without articular association, is a restorative test. Numerous osteosynthesis procedures can be utilized for these breaks and these methods have favorable circumstances and disservices and there is no agreement concerning the administration of these cracks. Randomized forthcoming examination included 40 patients with distal third extra-articular tibia shaft cracks (20 rewarded with supracutaneous -LCP and 20 with MIPO plate), were chosen dependent on the break example and grouped utilizing the AO characterization (AO/OTA types 43A and distal 42A-C as it were). Gathering I, 15% of patients accomplished relationship between 20-24 weeks, 70% of patients accomplished joining between 17-20 weeks and 15% of patients accomplished association ≤ four months. In Group II, 5% of patients accomplished association ≥ 24 weeks, 10% of patients accomplished relationship between 20-24 weeks and 40% of patients accomplished joining between 17-20 weeks and in 45% of patients association took ≤ four months. The Lower Extremity Functional Scale is 74.87% in supracutaneous plate bunch l with mean (60.3±4.87). Furthermore, 75.93% in Mipo bunch ll with mean (60.3±4.87).with no measurably noteworthiness, (P. esteem is 0.481). This examination results show a predominance of supracutaneous plate over MIPO method as far as expelled after association with most straightforward expulsion, lower paces of profound contaminations and shorter opportunity to full weight bearing. Though MIPO procedure gave off an impression of being profitable over supracutaneous plate as far as prompting a superior anatomical and fixed decreases of the crack, a fast and straight forward application, has a diminished careful time and a lower pace of association difficulties.
