Background: Critically sized surgical bony defects after enucleation of cystic bony lesions will not spontaneously heal. <br /> Purpose: This clinical study aimed to assess the osteoinductive potential of bioactive bone glass in the form of sticky bone in critical-sized surgical bony defects. <br /> Patients and methods: the present study is a randomized clinical controlled trial including 24 patients divided into two equal groups. Cystic lesions exceeding 2 x 2 cm were enucleated, and the defect was obliterated with bioactive bone glass particles in group 1 and bioactive glass sticky bone in group 2. Bone density was measured in grayscale units from digital panoramic radiographs immediately, at three and six months postoperatively.<br /> Results: The healing went uneventful, except for the exfoliation of graft particles through the incision line in groups 1. In group 1, the percentage of decrease in the bone density during the first three months is higher in group 1 than group 2 that was then increased by nearly the same percentage at the six months interval although statistically there is no significant difference between the two groups through out the study period.<br /> Conclusion: The bioactive glass prepared as the sticky bone has better intraoperative handling and workability, better soft tissue reaction during the healing period and higher bone density values of the grafted defects than when used solely although it hasn’t any radiographic statistical significant results regarding the studied parameters.

Purpose:<br /> Mandibular angle fractures (MAF) recorded many complications following various treatment techniques. Inter-fragmentary gap, strain and movement appear to be responsible for most of the complications with predilection towards the inter-fragmentary gap. This study aimed to calculate and assess the resulted post-treatment inter-fragmentary gap using cone beam computed tomography (CBCT) and its effect on the healing outcome and complications after mini plate fixation at Champy’s osteosynthesis line in MAFs.<br /> Patients and methods<br /> Twenty-five patients with MAF were subjected to intra-oral open reduction and fixation through semi-rigid min plate fixation near the superior border of the mandible at Champy’s osteosynthesis line. The linear inter-fragmentary gap in the mesio-distal plane and the bucco-lingual splay were measured at the inferior border of the mandible after fixation of the fractured bony segments in the final properly aligned position, immediately postoperative, on a CBCT. The healing process was clinically followed for 3 months postoperatively to record any complications.<br /> Results <br /> Uneventful healing was reported in the expected normal duration. At the inferior border of the mandible, the mean mesio-distal inter-fragmentary gap recorded a low value of 0.3 mm. In the bucco-lingual plane, inter-fragmentary lingual splay gap at the inferior border recorded a higher value yet with no clinical effect on healing;1.8 mm.<br /> Conclusion<br /> Semi-rigid Champy’s mini plate is dependable in MAF treatment with predictable acceptable mixed primary and secondary healing outcomes despite the resulted radiographic yet clinically insignificant inter-fragmentary gap and lingual splay at the mandibular inferior border

Dry socket (DS) is a very common post-extraction complication. Pain is the most important clinical symptom in DS. Although many studies provided variant treatment methods for pain alleviation, there is still a wide controversy about their efficacy. Ozone achieved promising results in the treatment of variant conditions including DS due to its powerful oxidation and metabolism enhancement capacity, however, no enough data is available in the literature about its efficacy in DS treatment; particularly the comparative studies. In the current comparative study, forty patients with DS were randomly divided into two equal groups. In Group I, a brief saline irrigation of the extraction socket was followed by ozone major autohemotherapy (AHT) which was performed by withdrawing a venous blood to be ozonized; and then being reinfused into the vain. A cotton pellet impregnated with Oleozon was lightly packed in the socket after a brief saline irrigation in group II patients. Oleozon was more effective than AHT regarding the required total treatment period and the number of the required analgesic tablets. Oleozon might have an increased capacity of oxygen delivery to the ischemic tissues than AHT. This might provide an evidence for the ischemic etiology of the dry socket development.

Purpose:<br /> Pharyngeal airway space (PAS) assessment after orthognathic surgery is crucial due to the possible resultant breathing hazards. This study compared PAS after mandibular set-back surgery and bimaxillary surgery and its consequent effect on the patients’ daytime sleepiness in class III dento-skeletal patients.<br /> Patients and methods<br /> Twenty-four patients with dento-skeletal class III deformity were divided equally into two groups; group A underwent mandibular set-back surgery while group B had bimaxillary orthognathic surgery through mandibular set-back and maxillary advancement surgeries. PAS area was measured on lateral cephalometric radiographs. Daytime sleepiness was assessed by Epworth sleepiness scale (ESS). All results were recorded pre-surgically, immediate post-surgically and at 6-months post-surgically.<br /> Results <br /> In group A patients, the PAS value at T0 (mean of 546.72±66.61 mm2) revealed a non-significant decrease after mandibular set-back surgery at T1 to reach a mean of 542.89±68.65 mm2, which appeared to minimally relapse at T2 to a value still less than T0 (544.00±68.62 mm2) with a final decreased PAS value. In group B patients, the PAS value (mean of 555.05±75.04 mm2) revealed a non-significant increase after bimaxillary surgery at T1 reaching a mean of 555.73±79.34 mm2 which re-increased at T2 to a mean value of 557.79±78.23 mm2. Following the pattern of PAS, the ESS recorded non-significant changes in both groups from the preoperative values to values at T1 and T2. <br /> Conclusion<br /> Despite of the resulted post-surgical different changes, orthognathic surgery appeared to have no significant effect on PAS area nor on daytime sleepiness in a six-month duration.

Abstract<br /> Introduction: Reconstruction of defects in the maxillofacial region can be challenging. Anatomy, location and size of the defect are major determinants of type of flap that could be used whether local, regional or distant. Nasolabial flap is one of the local flaps that can be used for reconstructing small to moderate size soft tissue defects, especially when microsurgical free flaps are less feasible due to lack of infrastructure, expertise or financial constraints.<br /> Aims and Objectives: To study the effectiveness of the nasolabial flaps in reconstruction of orofacial defects of various origins.<br /> Materials and Methods: A prospective study was conducted on 37 patients (49 nasolabial flaps) 25 unilateral flaps & 12 bilateral flaps. Of these, 30 patients had reconstruction following oncological resection. All flaps were inferiorly based, and 36 flaps required a second stage for separation after 3 weeks.<br /> Patients were evaluated for postoperative complications, flap uptake, donor site morbidity, postoperative extraoral scarring and patient’s satisfaction.<br /> Results: Good results in form of function and cosmesis were obtained in most of patients. Postoperative complications were relatively minor as tip of flap necrosis, and oro-cutaneous fistula. The average time taken for flap harvesting was 43 minutes for bilateral nasolabial flaps and 27 minutes for unilateral ones.<br /> Conclusion: The nasolabial flap is a simple and reliable flap that can be used in reconstruction of small to moderate sized defects in orofacial region with good cosmetics and functional outcomes.

Aim: The aim of this study was to evaluate the effectiveness of platelet rich fibrin (PRF) as sole graft material versus Nano crystalline hydroxyapatite in maxillary sinus augmentation with implant placement simultaneously.<br /> Patients and Methods: This was a randomized controlled clinical trial conducted on 18 patients suffering from atrophied maxillary ridge (less than 5 mm in bone height) for implantation indicating the need for maxillary sinus floor augmentation before implant placement. Group (A) received sinus augmentation with nano crystalline hydroxyapatite with immediate implantation (Nano bone ARTOSS GmbH hydroxyapatite particles) and Group B received sinus augmentation with PRF as sole graft material with immediate implantation. All patients were followed up for 6 months recording the progress of the healing both clinically and radiographically via CBCT and to evaluate the new bone formation.<br /> Results: Surgeries went uneventful in patients of both groups. No notable complications occurred during the surgical procedures and the healing period of the two groups. Radiographic results after 6 months showed that there was no statistically significant difference between the two groups. The highest mean value was found in (Group B) while the least mean value was found in (Group A). All implants were clinically stable at the time of abutment insertion, 6 months after sinus augmentation.<br /> Conclusions: The use of the PRF as a sole graft material in maxillary sinus augmentation proved to be a successful material that offers sufficient amount of natural bone in the sinus that cover all the surface of the inserted implant.

Aim: This study aimed to evaluate the insertion torque and initial stability of single thread implants versus double and triple thread implants.<br /> Methods: Forty two osteotomies were prepared in fresh bovine bone. The implants used in this study were 3 types according to the thread lead design,single thread implant, double and triple thread implants (n=14). Implants were inserted in bone blocks until reaching insertion torques (30 Ncm, 40Ncm and 50Ncm) then calibration of the part of implant inserted within bone was performed. The primary stability was assessed via resonance frequency analysis using the Osstell ISQ device. The removal torque of each implant is measured at torque 50N/cm. intergroup and intragroup comparisons were performed. The significance level was set at p ≤ 0.05 for all tests.<br /> Results: Regarding , implant insertion torque the highest value was found in single thread group followed by double thread group, while the lowest value was found in triple thread group. Primary stability results and removal torque revealed that, the highest value were found in triple thread group, followed by double thread group, while the lowest value were found in single thread group and there was a significant difference between different groups (p < 0.001) in all measured outcomes.<br /> Conclusions: When primary stability is a concern, as in low bone quality, double and triple threaded implants can provide greater primary stability and insertion torque. Double threaded implants combine optimum insertion speed and high primary stability and insertion torque in compromised situations.

Purpose: Scientific researches have focused attention on accelerating osseointegration around dental implants to increase their success rate. Accordingly, many materials and techniques have been developed to optimize bone remodeling, especially in immediately loaded implants. This clinical study aimed to investigate the impact of topical application of alendronate gel 1% on bone density around immediately loaded dental implants. Materials and Methods: Twenty dental implants were inserted in 16 patients. Cases were divided randomly into two equal groups; Group I (study group): 10 implants were placed after injection of alendronate gel 1% in the drilling sites. Group II (control group): 10 implants were placed immediately after drilling; no material was applied to their osteotomy sites. All implants were loaded immediately within 24-72 hours. In each implant recipient sit, bone density was determined pre-operatively using cone-beam computerized tomography (CBCT), then re-evaluated after six months of implant placement and loading.<br /> Results: The mean bone density pre-operatively for Group I and Group II were 557.30±132.06 HU and 567.62±110.72 HU respectively. After six months, the corresponding values were 852.03±176.43 HU and 670.11±117.71 HU respectively, indicating a statistically significant difference in bone density (P= 0.014) between both groups. Conclusion: Topical application of sodium alendronate gel increases bone density around dental implants, which can increase the success rate of immediately loaded implants.

Background: The dentigerous cyst is the second most common developmental cysts of the jaws. Despite being asymptomatic in many cases, untreated lesions can reach significant sizes and result in extensive bone resorption. Associated complications may include facial asymmetry, teeth mobility, nerve compression, and pain. Large extensive dentigerous cyst are more difficult to manage.<br /> Aim of the study: This study was conducted to evaluate the management of extensive dentigerous cysts in adults as well as the associated potential risks and complications.<br /> Patients and methods: Fourteen (8 males and 6 females) patients with age range of 20-55 years (mean age of 33.9 years) who had large dentigerous cysts were included in this study. Enucleation of the cystic lesions along with the associated teeth was performed. Patients were clinically and radiographically evaluated for one year postoperatively.<br /> Results: Nine mandibular (64.3%) and 5 maxillary dentigerous cystic lesions (35.7%) were operated. No surgical postoperative complications were encountered. Radiographic evaluation showed adequate new bone formation in the surgical defects within 6-12 months.<br /> Conclusion: Untreated dentigerous cysts can reach a significant size. Extensive dentigerous cysts can be adequately treated with careful enucleation. Extensive dentigerous cysts may be associated with an increased risk for transformation into more aggressive lesions.

Background: A retrospective study was done to evaluate the success rate of immediate reconstruction by split rib bundle bone grafting after segmental resection of Aggressive Pediatric mandibular tumors.<br /> Materials and Patients: The present study enrolled sixty-one pediatric patients with aggressive mandibular tumors that had been treated during the period from January 2008 to December 2018. All patients were examined clinically and radiographically by Orthopantomograms, CTs and CBCTs. Radical segmental resection with resultant mandibular continuity defects were thus created followed by immediate reconstruction with non-vascularized Split Rib Bundle Bone Graft (SRBBG). Patients were then rehabilitated by osseointegrated implants with fixed or removable partial dentures. Success of reconstruction was assessed by the percentage of complications, interincisal opening and patient satisfaction. Assessment was performed at 1,3,6 and 12 months postoperatively. All patients were followed up for 4-7 years. <br /> Results: Successful reconstruction was accomplished in 55 patients (90.16 %). Successful dental rehabilitation was accomplished in 49 patients (89%). Three patients had complete failure due to severe postoperative infection. Another three cases had partial resorption of the graft due to moderate infection to whom re-augmentation by another rib graft had been performed. <br /> Conclusion: Pediatric aggressive mandibular tumors should be treated in an aggressive manner relative to its biologic behavior and immediate reconstruction is advocated.<br /> The Split Rib Bundle Bone Graft is an adequate alternative for mandibular reconstruction in the absence of microvascular surgery as it shows early revascularization thus permitting rehabilitation with successfully osseointegrated dental implants.

The aim of the study is to assess the efficacy of the Lingual Ring Splint (LS), anterior repositioning splint (ARS) and stabilizing splint (SS) in management of anterior disc displacement with reduction (DDWR) for the relief of pain and improving mandibular movements. Thirty patients diagnosed with DDWR were included in this study. The participants were randomly assigned into one of three equal groups using a computer-generated randomization schedule receiving the assigned splint for each group, with specific instructions regarding the time of using it and exercises. Follow up was made after 1 and 6 months to test pain score and mandibular range of motion. Pain score improved in all 3 groups with statistical significance with better results is SS group than other two splints. Also, there was an increase in maximum mouth opening (MMO) with the highest measurements in SS group with statistical significance difference. There was no statistical difference regarding lateral excursion between all groups.

Aim of the study: Evaluation of the inferior alveolar nerve (IAN) neurosensory function, postoperative pain and edema following the placement of an implant with inferior alveolar nerve lateralization using piezo-surgery versus conventional rotary instruments.<br /> Materials and methods: Twenty four partially edentulous patients were selected for this study. Twelve patients underwent inferior alveolar nerve lateralization for Implants placement using Piezosurgery device (Group A), while the other twelve patients underwent inferior alveolar nerve lateralization for implant placement using conventional rotary surgical bur (Group B). Operation duration, postoperative pain, edema, and patient satisfaction were primary assessed and compared between the two groups at 2, 5 and 7days postoperatively, also inferior alveolar nerve affection as a secondary outcome was assessed subjectively and objectively and compared between the two groups throughout the follow up intervals occurred at 2, 8 & 24 weeks postoperatively. <br /> Results: There was a statistical significant difference in all of the primary and secondary assessments between the two groups in favor of group A at all of the follow up intervals, except at the operation duration assessment where piezosurgey ( Group A) had statistically significant higher operation duration than group B. <br /> Conclusion: The inferior alveolar nerve lateralization (IANL) technique using conventional surgical burs has a higher initial rate of sensory dysfunction, postoperative pain and edema than with using Piezosurgery. The somatosensory evoked potential method is considered more informative, reliable and diagnostic parameter than other subjective and conventional clinical methods.

Objective: This prospective study evaluated the impact of ozone gel, conventional PRF (C-PRF) and advanced PRF (A-PRF) on pain and trismus when applied after surgical extraction of impacted mandibular third molars.<br /> Materials and Methods: This study included 48 patients with impacted mandibular third molars. They were randomly divided into 4 groups, group I (control); didn’t receive any material in the socket, group II: sockets received ozone gel, group III: sockets received PRF while in group IV: sockets received A-PRF. Pain assessment using VAS, analgesics consumption, and maximum mouth opening were evaluated on day 1, day 3 and day 7 follow-up. <br /> Results:<br /> Less values of VAS pain scores were recorded in group II in comparison with the control group on day 1, day 3 and day 7 with a statistically significant difference of (P=0.018), (P=0.044) and (P=0.015) respectively. The analgesics consumption showed a statistically significant difference in group II compared to group I (P=0.020) and (P=0.021) on day 1 and day 3 respectively, but day 7 was statistically insignificant (P=0.165). Maximum mouth opening was statistically significant (P=0.042) on day3 in group II when compared with group I.<br /> Conclusion: The present study shows that ozone gel can be of paramount importance in minimizing post-operative symptoms as regard to pain and trismus following the extraction of impacted mandibular third molars and appears to improve patient’s relief and quality of life after surgery.

Objectives: The purpose of this study was to compare IMF involving placement of titanium arch bars applied using screw fixation (smart lock hybrid arch bar) with Erich arch bars secured with circum-dental wires to the maxilla and mandible in the treatment of mandibular fractures. <br /> methods: This study was conducted on 36 patients with mandibular fractures. The patients were divided randomly into two groups. MMF was performed to all cases. In group (A) All patients had MMF using Smart Lock Hybrid arch bar. While in group (B) Patients had MMF using Erich arch bars. The clinical evaluation included assessment of gingival health via GI, number of gloves penetration for the operator and assistant, time consumed for application/removal of the device, complications during surgery, as well as, patient satisfaction via questionnaires (HADS, UW-QOL v4 and VAS) and cost.<br /> Results: Smart Lock Hybrid arch bar group showed significant lower gingival index than Erich arch bar group. Group A showed shorter time for application or removal of the arch bar than Group B. In group A, patients showed complications such as gingival growth over the eyelets and screws, mucosal tears and screw looseness. One case in group A needed endodontic treatment for the lower first molar as a result of root injury. Group A showed better patient satisfaction score .The Smart Lock Hybrid arch bar was higher cost than Erich arch bar. <br /> Conclusion: Smart Lock Hybrid arch bar was a perfect choice as an alternative to Erich arch bar for treatment of mandibular fractures.
