Title: Easy-method for indirect bonding
Biography:
Federico Rosti has completed his Master of Science in Dentistry in 2007 from and in 2011 he completed the postgraduate in Orthodontics from University of Pavia School of Medicine. His research interest includes class 2 corrections, impacted canine, lingual orthodontics, friction analysis.
Abstract:
Easy method for indirect bonding: Brackets positioning is the most important phase in fixed orthodontics. Accuracy in bonding phase allows reaching easily a correct tooth position and decreasing the need of repositioning brackets. Indirect bonding allows transferring the right bracket position from model casts to patient's teeth. This technique has several advantages: best comfort during in office practice, better brackets positioning, less root resorption due to round tripping and shorter appointments for bonding and rebonding. The aim of this work is to illustrate a simple and homemade technique to realize a PVS mask with a thermal-print coat to transfer bracket position from cast to the patient's teeth. While indirect bonding is recommended in vestibular bonding, it is necessary in lingual orthodontics because of the need of extra skills to bond bracket in the palatal side of the teeth. You can also customize bracket's base with composite resins to correct morphological anomalies, reducing the need of wire bending. This method of indirect bonding is simple and allows physicians to reach, after a short learning curve, good clinical results.

Title: Intraoperative navigation in oral and maxillofacial surgery
Biography:
Emanuele Zavattero has completed his PhD at Torino University. He is pursuing his Post-doctoral studies at Torino University, Division of Maxillofacial Surgery. He has published more than 45 papers in scientific international journals. His research interest includes Navigational Surgery and Coputer-Assisted Surgery.
Abstract:
Aim: Aim of this study is to explore the indication and application of intraoperative navigation in cranio-maxillo-facial surgery. This study introduces our experience with the use of navigational techniques and summarizes its advantages in the oral and maxillofacial field.
Patients & Methods: 64 (105) patients including 88 zygomatic-orbital-maxillary fractures, five craniofacial fibrous displasia, five midface tumors, six chronic sinusitis and one case with facial foreign body were enrolled in the study. CT scans were performed and data imported onto the navigational platform (Brainlab, iPlan ENT-CMF 3.0) to plan the operation. The osteotomy lines, amount and range of resection, the reduction position of bony segments and the position and shape of the implants were determined and displayed by preoperative simulation with mirroring and virtual procedures. All operations were performed under the guidance of navigation system (Brainlab, Germany). The postoperative control was obtained for each patients by image-fusion, superimposing the preoperative CT dataset with the virtual template onto the postoperative CT dataset.
Results: All operations were performed successfully with the guidance of real-time navigation. Through registration, an accurate match between the real anatomy and the CT images was achieved (mean error < 1 mm). Good coincidence between virtual simulation and surgical result was achieved in all cases. All patients healed uneventfully and function and profile was improved significantly.
Discussion & Conclusion: Several studies in cranio-maxillofacial surgery have addressed the benefit and outcome improvement of computer-assisted surgery. In oral and maxillofacial surgery the demands for precision, optimal function and aesthetic results are high and the complex and distorted anatomy with loss of anatomic landmarks makes this type of surgery particularly difficult. The intraoperative control is achieved by real-time instrument tracking during surgery, keeping in mind that registration techniques used is a key element in precision of surgical navigation. To conclude, computer-assisted preoperative planning and surgery thus advance the difficult surgical field of orbital surgery and computer-assisted surgery should be practiced as part of the surgical routine of posttraumatic and primary orbital reconstruction.

Title: Clinical comparison between free gingival graft healing with and without low level laser therapy
Biography:
M T Baghani has completed his DDS at Shahid Beheshti University and he is pursuing his Post-doctoral studies in Prosthodontics at Shahed Dental School. He has published five papers in reputed journals.
Abstract:
Background: Free gingival graft is one of the most predictable procedures for gingival augmentation, but patients discomfort and pain during healing period of palatal donor site is a significant concern.
Aim: The aim of this study was to compare between free gingival graft healing with and without low level laser therapy in class one and two miller gingival recession clinically.
Material & Methods: 12 individuals needing bilateral gingival graft in the mandibular arch were enrolled in a double-blind study. Each individual had a 30-days interval between the two surgeries. The side receiving application of laser was defined as test side and was established upon surgery; laser application was simulated on the control side. The laser was applied in the immediate postoperative period and after 48 hours, and patients rated pain on a scale of 0 to 10 at 3 h, 24 h and 7th day after surgery, representing their experience of pain, respectively. Photographs were obtained at 0 and 30 days postoperatively and evaluated by three periodontists.
Results: 10 patients could make the study to the end. Laser group showed better color matching (P=0.04, P=0.05, P=0.015) and healing in donor site (P=0.000) in day 7, 14 and 21 after surgery and showed less discomfort and pain in 24 h (P=0.007). No statistically differences were observed between laser group and control group in terms of bleeding index and pocket depth and gingival index and gingival margin place (P=0.625).
Conclusion: According to the results of this study, the low level laser therapy can improve the discomfort and pain 24 h after surgery and promote donor site wound healing and color matching in graft site.
