Children exhibit many pathological lesions involving the jaw bones. Radicular cysts are common inflammatory odontogenic cysts that arise from epithelial cell rests of Malassez due to periapical infection, originating from pulpal necrosis of a non-vital tooth. Radicular cysts are relatively rare in the primary dentition because of the distinct biological cycle of primary teeth. It comprise about 52% to 68% of all the cysts which affect the human jaw. Radicular cysts are usually asymptomatic, unless secondary infected, and discovered during routine dental radiographic examination. The lesion is seen radiographically as a circumscribed, well-defined radiolucent area bound by a thin radiopaque line. The treatment of the cysts can be either non-surgical management or surgical management being either marsupialization or enucleation. However, the treatment option should be kept as conservative as possible.

Background: Immediate implants have been commonly used for the single or bi-rooted teeth. However, it was a challenge and an intriguing dilemma with respect to molar teeth, due tothe presence of multiple factors such as: multiple root morphology,achieving implant stability and bone to implant contact.The aim of this study was to assess the efficiency of using A-PRF-autograft mixture around implants placed immediately in mandibular molar region from aclinical and radiographic point of view.Patient and methods: This study was carried out as a randomized controlled clinical trial in which twenty patients needing extraction of unrestored mandibular molars and placing of immediate implant, were selected. Patients were divided into two groups randomly; the study group where the resultant gap following the immediate insertion of a molar implant was filled with A-PRF-autograft mixtureand the control group where peri-implant gap was filled with autogenous bone graft alone.The studied variables were the degree of facial swelling, marginal bone height and the bone density around the immediately installed dental implants. The period for follow up was after six months. For statistical analysis,Mann- Whitney U test was used.Results: The study group showed better results in the clinical and radiographic studied variables. A significant difference was seen regarding the marginal bone height.Although, regarding bone density and swelling, more acceptable results have been seen within the study group, the results showed no statistically significant difference between both groups.Conclusion:The results assured the efficiency of using A-PRF-autograft mixturewith concurrent placement of immediate implants in the lower molar region and highlighted their promising effects on bone and soft tissue healing.

Hydroxyapatite cement versus autologous abdominal fat in obliteration of frontal sinus after trauma
Hesham
Fattouh
Objectives: To assess the efficacy of the hydroxyapatite (HA) cement alone or with simvastatin in obliteration of the frontal sinus after trauma as an alternative to the widely used autologous abdominal fat.Patients and Methods: 4 out of 9 patients underwent frontal sinus obliteration with autologous abdominal fat (Fat group) and the remaining 5 patients were obliterated with HA cement (HA group) where 2 patients out of those 5 patients were obliterated with HA alone and the remaining 3 patients of this group were obliterated with HA cement mixed with simvastatin as an osteoinductive material. Results: Both the autogenous fat and the HA cement has a comparable results; Fat obliteration failed in 1 patient and none of the patients in the HA cement group has acquired any complications that necessitates the material removal, no significant difference in the results obtained from the HA cement when used alone or when mixed with simvastatin.Conclusion: HA cement is a promising obliterating material in frontal sinus obliteration with comparable results to autogenous fat with the advantages of no donor site morbidity and the potential for complete osseointegration. Addition of simvastatin to the HA cement does not seem to enhance the obtained results.

Hesham
Fattouh
Objectives: To evaluate the socket shield technique and compare the survival, stability, esthetic outcome and complication rates of immediate implants in the esthetic zone placed using this technique with the traditional guided bone regeneration technique.Patients and Methods: 20 Patients were enrolled in this study, they were randomized into two equal groups, after receiving a post extraction implant in the esthetic zone; Group I patients were managed with guided bone regeneration technique, while group II patients were treated with socket shied technique. Functional and esthetic outcomes of the treatment in term of implant survival and marginal bone level were evaluated.Results: Implant survival rate after 1 year was 100% in both groups. Implants inserted with the socket shield technique demonstrated better values of marginal bone level and were statistically significant.Conclusions: Socket shield technique is a highly promising addition to dental implantlogy that seems to be a feasible surgical option characterized by better esthetic outcomes when compared to guided bone regeneration technique.

Long-Term Esthetic Results of a Modified Technique of Bilateral Cleft Lip Repair
Hassan
Abdelghany
Purpose: To evaluate long-term esthetic results in the bilateral cleft lip repair by a modified technique characterized by prolabial self-elongation and orbicularis oris muscle reconstruction in one stage, using anthropometric measurements.Patients and Methods: Fourteen patients (8 were males and 6 were females) had their bilateral cleft lip and nasal deformity repaired simultaneously by modified technique characterized by prolabial self-elongation and orbicularis oris muscle reconstruction in one stage, during the period from 1999 to 2002. Direct and indirect anthropometry were applied to all patients to evaluate the long term esthetic results.Results: The long term esthetic results were satisfactory in all patients. There were no acute complications requiring re-surgery. In most patients, nasal length, nasal tip projection, columellar length, and upper lip shape were appropriate. Nasal tip protrusion, nasal width, upper lip height, and vermilion-mucosal height were within normal limit. The measurements were observed to be symmetrical; left and right measurement data were not significantly different. Conclusions: This modified technique is proved to be a valuable technique on the long term basis in repair of bilateral complete cleft lip which has its important impact on esthetic results.

Purpose: To validate the accuracy of orthognathic 3D Printed final occlusal splints produced with in office desktop 3D Printer and comparing the accuracy with the conventional acrylic resin splints.Subjects & Methods: 10 Orthognathic Surgery patients were included in this study. All surgeries were performed by the same Surgeon. Computer virtual planning for Orthognathic Surgery for all cases was performed in Pro- Plan Software version 3.0 (Materialise, Leuven, Belgium) with the proper work flow ending with splint design. Final Splint with 3D Printed with an In Office Desktop Printer (Formlabs), also conventional work up was performed on all cases and acrylic resin conventional splint was fabricated. The final splints were clinically evaluated; also the 3D Printed splint image was superimposed on the virtual splint image and distance errors recorded from 3 landmarks on the upper dental model. This superimposition was repeated with the conventional splint and compared with the virtual splint and distance errors recorded. Results: All final splints (3D Printed and Conventional) accuracy was reflected as clinically acceptable. The distance error (Absolute) ranged from 0.17 – 0.82 mm and an overall mean distance error of 0.44 mm with respect to the 3D Printed splint (Final Splint2) when superimposed on the virtual design splint (Final Splint1). The distance error (Absolute) ranged from 0.26 – 0.75mm and an overall mean distance error of 0.39 mm with respect to the conventional splint when superimposed on the virtual splint (Final Splint1)Conclusion: This study has validated the accuracy of the 3D printed final splint as the mean distance error of 0.44 mm lies within the clinically acceptable range. In addition, the conventional splint design still proved highly accurate with a distance error of 0.39 mm.

Mohammed
ElSholkamy
Purpose: To evaluate the volume of bone graft that can be harvested from the mandibular symphysis and compare it with the bone volume needed for secondary grafting unilateral alveolar clefts using a computer-aided design (CAD) software program based on 3 Dimensional Cone Beam CT Scans. In addition, to study the bone fill of the mandibular symphysis graft in the alveolar cleft.Subjects & Methods: The subjects were 12 patients with unilateral alveolar clefts who underwent Cone Beam CT Scans 1 week prior to procedure. Using a 3D Analysis Software, the available bone that can be harvested from the mandibular symphysis area was determined using CBCT. Also, the volume of the Alveolar cleft defect was calculated preoperatively to assess the sufficiency of the symphyseal bone graft. All patients underwent secondary alveolar cleft grafting with mandibular symphysis bone. Six months postoperatively, CBCT was used to evaluate the amount of bone fill of the alveolar cleft.Results: The mean harvestable symphysis bone volume including the lingual cortex was 2.4 cm3 (range: 1.4–4.3 cm3). The actual harvested particulate symphyseal bone graft volume was calculated during surgery and was 2.62 cm3 (range: 1.6–4.0 cm3). The preoperative mean volume of the unilateral alveolar cleft defects was 1.9 cm3 (range: 1.1- 2.85 cm3). The mean postoperative bone fill ratio of the unilateral alveolar cleft was 79% (range 54% to 96%) 6 months postoperatively.Conclusion: This Study showed that the mandibular symphysis provided sufficient bone volume for secondary unilateral alveolar cleft grafting. Also, the mandibular symphyseal bone graft provided adequate bone fill of the alveolar cleft 6 months postoperatively..

Purpose : Cranio-facial trauma with Frontal bone defects develops a frustrating facial deformity with a resultant obvious bad appearance. Conventional frontal defect reconstruction often develops an asymmetric facial contour due to the lack of ultimate accuracy. This study aimed to utilize the computer guided 3D planning, designing and printing technology to reconstruct frontal bone defects using Poly-ether-ether-ketone (PEEK) material to reach a more precise prosthesis for better frontal bone contour and esthetics. Patients and methods: A total of six patients suffering from Frontal bone defects were included in this study from the department of oral and maxillofacial surgery, faculty of Dentistry, Cairo University. All the patients were subjected to clinical and CT radiographic examination to assess the extent of the defect and its implications. The computer software was used to manipulate the CT data to create a skull template and an anatomically precise prosthesis through “mirroring” using the sound contra-lateral skull as a reference. The prosthetic part was 3D printed with PEEK-patient specific implant (PSI) material and was adapted and fixed in place through either coronal incision, in four patients, or the pre-existing frontal scars, in two patients. After a 12 months follow-up, clinical inspection and palpation was performed. Postoperative CT imaging was done to validate the accuracy of the implanted PEEK-PSI part in relation to the preoperative computerized plan.Results: A male predominance in all cases with a mean age of 46 years was found with a dominating etiology of motor vehicle accidents (MVA). The surgeries in all cases proceeded uneventful. Surgical site healing was normal without any signs of infection. The anatomic frontal contour and facial esthetics were admirable. The CT scan revealed the precise adaptation of the prosthesis in place without any pathology. Preoperative virtual plan fell precisely in place when compared with the post-surgical CT images after the prosthesis fixation. Conclusion: Computer guided 3D designing and printing of the prosthesis in frontal defect reconstruction was highly beneficial; higher accuracy and less obtained surgical errors due to the perfect fit of the prosthesis, along with the resultant reduction of the surgical time was documented. The integration of computer programs in surgery planning and custom prosthesis designing in defect reconstruction is highly advisable due to its great benefits and accuracy.
