Title: Optimizing periodontal conditions around the maxillary included canine: Proposal of a surgical decision tree

Biography:

Jean-Marc Dersot is the doctor of Dental Surgery. He has completed MSc, PhD and the former assistant-professor at the Periodontology department of Paris 5, former president of the French Society of Periodontology and Oral Implantology (SFPIO), associate member of the National Academy of Dental Surgery (ANCD), international member of the American Academy of Periodontology (AAP), expert near the Paris Court of Appeals, practice limited to periodontics, oral surgery and implant - Paris – France. 

Abstract:

Currently, it is considered acceptable to hold dolphin, orca, beluga and other cetaceans in captivity for human entertainment. Clearly, among the most emotionally and socially complex of all creatures, there is an urgent need to recognize and acknowledge the sentience of these beings. Moreover to rewrite global protocols and accepted norms in order to drive a systematic and comprehensive phasing out of this archaic, cruel practice. Cetaceans are to this day still being taken from the wild, with devastating consequences for those captured and family members left behind, in order to fulfill demand for hotels, waterparks and other facilities around the world. We must discuss and become the catalyst for an end to this.

Title:  Novel approach for soft tissue management in esthetic zone

Biography:

Ahmed Halim Ayoub has accomplished diploma and master degrees is from Seville University, Spain. He developed expertise in bone augmentation and sinus elevation and has special interest in bone healing. Currently he is the visiting lecturer in Bari University, Italy. He provides live training throughout directing dental implant post graduate training in Egyptian society of oral implantology, London oral restorative Academy, and London dental education services. He is a distinguished speaker and presents at international conferences and teaches in the Rome, Europe and the Middle East. 

Abstract:

Management of peri-implant soft tissue is as important as preserving the peri-implant bone level. Many techniques, approaches, and materials have been used to achieve healthy, keratinized, esthetic peri-implant soft tissue or correct/augment any deficiency in it.  Platelets rich fibrin (PRF) or concentrated growth factors (CGF) is one of those materials that can be used to achieve soft tissue augmentation, especially in esthetic zone. Osseointegration is no longer considered the only parameter upon it we can judge the success of the implant therapy. Even precise ceramic duplication of the contour, shade, and translucency of natural dentition may still result in an aesthetic failure if the gingival profile, color and texture are compromised. Therefore, the functional and aesthetic success of implant treatment in the anterior esthetic zone depends not only on the quality of the restoration but also on the final aspect of the contour and stability of the marginal gingiva and the proximal papillae in harmony with the adjacent teeth.

Title: Hyperactivated signaling pathways of chemokine RANTES/CCL5 in osteopathies of jawbone in cancer and autoimmune diseases: Neglected dental cause of systemic diseases?

Biography:

Johann Lechner is a dentist, Naturopath and the Head of the Clinic for Integrative Dentistry in Munich, Germany. He also serves as a member of executive board of DAH (German Association for Research on Disturbance Fields and Regulation). Besides extensive lecture and seminar activities in USA, Europe and China, he published numerous articles and hitherto nine books in German about Holistic Dentistry and Integrative Medicine. He has published 6 PubMed indexed scientific papers discussing immune messengers and hyperactivated signaling pathways by RANTES/CCL5 in jawbone and systemic interference. These studies done by him are the first ones worldwide and contribute to generating a new field of Maxillo-Mandibular Osteoimmunology.

Abstract:

Despite significant therapeutic advances most malignancies, as well as adenocarcinomas of the breast, remained incurable. At the same time, the importance of the microenvironment surrounding the tumor cells with “silent inflammation” increases. To check the suspected tumor-relevant inflammatory cytokine sources in fatty degenerative osteonecrotic jawbone (FDOJ), we analyze these conspicuously altered jawbone areas to assess the expression and quantification of cytokine expression. In 38 tumor patients we determine the levels of cytokines by bead-based Luminex® analysis in samples of FDOJ. Striking is the high content of chemokine RANTES/CCL5 (R/C) in all 38 jawbone tissue samples of cancer patients. A single case is characterized by high R/C levels in FDOJ sample and simultaneously by metastasizing cells inside the FDOJ sample. The R/C expression in all 38 FDOJ samples is on average at 35 fold higher compared to healthy jawbone. R/C interacts on several levels in immune responses and is considered in scientific literature as pathogenetic key point in tumor growth. The study supports a potential mechanism where FDOJ is a mediating link specifically in breast cancer (MaCa) and its metastasis. R/C is thus involved intensively in oncogenic propulsion progress developments. The authors conclude from the data of FDOJ analysis that these areas express hyperactivated signal transduction of the chemokine R/C, induce  pathogenetic autoimmune processes in tumors, MaCa and its metastasis and serve as a possible cause. The authors hypothesize that such changes in areas of improper and incomplete wound healing in the jawbone may lead to hyperactivated signaling pathways, and result in unrecognized sources of silent inflammation which may contribute to systemic disease patterns like cancer. Combining the R/C signal induction of tumors and the information we collect illustrated, it may be suggested to involve FDOJ in an integrative concept for tumor therapy.

Title: Keys to success for implants placement with immediate loading

Biography:

Sameh Samy Abdou has completed master degree in prosthodontics in 1992 from Alexandria University Egypt. He has received diploma in Implantology from Sevilla University Spain in 2007. He has been the Consultant in Prosthodontics & Implantology since 2002. 

Abstract:

The introduction of osseointegrated implants in dentistry represents a turning point in dental practice. The concept of immediate loading has recently become popular due to less trauma, reduced treatment time, high patient acceptance and better function and esthetics. A careful case selection, proper treatment plan, meticulous surgery and proper design of prosthesis are essential for optimal outcomes when this approach is adopted.

Title: Immediate post-extraction molar dental implants

Biography:

Dr. Traub obtained his dental degree at Creighton University in Omaha, Nebraska. He completed his oral and maxillofacial surgery residency training at Cook County Hospital in Chicago.  He maintains a private practice in Albuquerque, New Mexico (USA) and is on the board of directors of the American Institute of Oral Biology (AIOB).  He is a fellow of numerous oral and maxillofacial surgery associations, both in America and internationally. He lectures extensively throughout the world. 

Abstract:

Contrary to early dogma related to titanium implant integration, 100% bone to metal contact, complete wound closure, and peri-implant socket bone graft placement are not absolute determinants of success. In fact, adequate stabilization in an extraction site with normal osteogenic healing potential leads to the same result in molar wounds, both in the maxilla and mandible, with essentially equal predictability.  This lecture documents a 12-year private practice clinical investigation using a single brand (Biomet 3i) implant for both root canal and non-root canal teeth with a standard follow-up protocol for over 700 consecutive cases.

Abstract:

In front of the maxillary lateral incisor agenesis (MLIA), the therapeutic options are multiple. Opening or closure of the space, extraction of the sometimes peg-shaped contra-lateral incisor, removable temporary prosthesis, Maryland bridge, bonded cantilever bridge, conventional bridge, implant. MLIA diagnosis is made early by radiographic examination and, from the beginning of the orthodontic phase, it is important to know if the implant solution can be performed. The implant feasibility must meet certain conditions concerning: the bone corridor: height and thickness of the bone, the width of the mesiodistal space and parallelism of the roots of the two adjacent teeth. However, in 60 to 85% of cases, it is necessary to reconstruct the bone and/or gingival structures beforehand. A lingual treatment of a bilateral MLIA illustrates this thinking. The cost/benefit/ safety ratio, but also the age at which the orthodontic treatment is performed, can help to choose the most suitable and most durable solution. Several studies, carried out on the maxillary anterior area, specify what can be the evolution of an implant, 15 to 20 years after its installation, and the results are quite disappointing.

Title: Special Session: Recurrent aphthous stomatitis; Overview and suggested management modality in pediatric dentistry

Biography:

Dania Siddik is a consultant pediatric Dentist based in London specialises in the management of dental injuries, sedation and general anaesthesia for anxious children and oral surgery. In addition to practising dentistry, she also held a position teaching both undergraduates and post graduates at the King’s College University pediatric dentistry department. She is a regular examiner for the MJDF and ORE courses at the Royal College of Surgeons of England. 

Abstract:

Aphthous ulcers also known as recurrent aphthous ulcers, aphthous stomatitis, recurrent aphthous stomatitis [RAS], or canker sores; are a common oral mucosal disease. They are ulcerations with no known cause and a wide spectrum of severity and frequency of recurrence. Clinically, RAS has different presentations. It can consist of solitary or multiple ulcers, usually on the non-keratinized oral mucosa. It has been proposed that aphthous ulcerations represent an autoimmune reaction and may be precipitated by stress or hormonal changes. I will be discussing the importance of right diagnosis and monitoring with a specific scoring system. I will discuss as well the predisposing factors, the microorganisms implicated in aphthous ulcers as well as different treatment modalities for the pediatric patient. I will discuss the clinical presentation of this condition together with the current views on the aetiology and pathogenesis of the disease.

Title:  Keynote Forum: Evaluation of interleukin-1 beta level and oxidative status in gingival crevicular fluid during rapid maxillary expansion

Biography:

Nur Ozel does private practice in Izmir and is currently running as a clinician in Izmir Education Dental Hospital, Izmir/Turkey. She is a member of the Turkish Orthodontic Society and an affiliate member of the American Dental Association. She has been a certified incognito System user since 2017. To date she has published 5 various articles in various journals in dentistry. 

Abstract:

The levels of interleukin-1beta (IL-1β), nitric oxide (NO), total antioxidant capacity (TAC), and total oxidant status (TOS) in gingival crevicular fluid (GCF) were determined during rapid maxillary expansion (RME) treatment. Fourteen patients (10-13 years old) were included. A modified hyrax appliance was used for the treatment. After periodontal parameters were recorded, GCF was collected from the first molars at each observation [T1:baseline: 14 days after periodontal prophylaxis and instructions; T2: 1 day later hyrax inserted, at passive position; T3:1 week later; after the first activation; T4: after 2 x 1/4 activation; T5:after 7 x 1/4 activation; T6: after 14 x 1/4 activation; T7:retention period on the 1st month; and T8:retention period on the 3rd month]. Although the levels of IL1-β, NO, and PD increased significantly from T1 to T2, the GI, BOP%, and PI remained unchanged throughout treatment. GCF volume at buccal and palatal surfaces increased significantly from T1 to T4, T6, T7, and T8. The parameters in GCF and TAC levels were not only higher at palatal side in comparison with buccal, but also TOS levels increased at both buccal and palatal sides. In this study, the differences of oxidative status and IL-1β levels during RME treatment could be attributable to orthopedic effect of the heavy forces on maxilla and minimal orthodontic forces on teeth applied by the RME apparatus.

Dental Design Lab, Greece

Title: Special Session: Dental prosthetics with predictable outcome

Biography:

Alkis Konstantinopoulos completed the Greek National School of Dental Technicians in 2005. He owns dental laboratory which is nowadays one of the most state of the art and fully equipped in Greece, “Dental Design Lab”. In addition, he has published many papers in reputed journals while also he has been invited as an expertise speaker to many conferences worldwide. Furthermore, he is also cooperating with many dental technology companies as a technical consultant. 

Abstract:

This presentation is to show how predictable outcome can be achieved in high aesthetic dental prosthetics through digital designing and manufacturing techniques. One of these techniques is 3D prototype printing with DLP printers through the use of certified surgical resins and milled resins prototypes. In addition, this presentation will show how patient wishes/orders can be fulfilled and imprinted in the final outcome through digital designing tools like Exocad True Smile and also how the use of polarized dental photography can lead to an exact and correct communication between the patient, the dentist and the laboratory. As a result, function difficulties are avoided while also changes and/or remakes are not necessary which means the durability and strength of the final prosthesis are not affected. Finally, all above techniques diminish manufacturing and delivery time while also the patient’s stress period as he/she is certain for the final outcome of the prosthesis since the beginning of the procedure.

Title:  Intrusive luxation: From reflexion to decision: About two case reports

Biography:

M Lferde is the former intern at Ibn Sina University Medical Center, resident in pediatric dentistry, faculty of dental medicine at Mohammed V University of Rabat Morocco. She is a member of the committee bureau (communication manager) of the association of internal and residents dentists of Rabat. 

Abstract:

Dental intrusion corresponds to the axial displacement of the tooth into the alveolar bone. Rather infrequent, it represents between 0.3 and 1.9% of traumas in permanent dentitions. It occurs mostly in children between the ages of 6 and 12 and generally affects only one tooth. Case report First case: The patient, B.K, was a 9-year-old child that reported to the Rabat Dental Treatment and Consultation Center (DTCC) in an emergency following a fall at home. After clinical and radiographic examination, the diagnosis of the intrusion of the two immature central maxillary incisors was made. The management of the case consisted of the therapeutic abstention with regular followup. Spontaneous re-eruption of the teeth occurred 3 weeks after the trauma. Second case: The patient Z. M was a 14-year-old teenager, who was sent to the DTCC of Rabat in an emergency following a public road accident. After clinical and radiographic examination, the diagnosis of the intrusion of the upper right central incisor was made. The treatment consisted of a surgical repositioning of the tooth. The clinical and radiological follow-up of the two clinical cases was spread over 18 months. Intrusive luxation is the most severe form of dental trauma. Axial shock usually causes considerable pulpal and periodontal complications. The treatment is complex since the prognosis is often unfavorable with inevitable complications. To date, no treatment has been found better than another. Besides, the incidence of pulp necrosis, all methods combined, varies from 45% to 96%. The therapeutic modalities depend on the age of the child, the stage of the root formation but also the importance of the vertical dislocation. Intrusive luxation, although rare, is the most severe form of traumatic emergencies. successful treatment requires a rigorous clinical and radiographic examination that allows reasoned decision-making ranging from therapeutic abstention to active repositioning.

Title: SS Fly: A therapy for root re-implantation

Biography:

Francesco Campione specializes in CAD / CAM technology at the University of Zurich. He collaborates with Prof. Ernesto Rapisarda for the University of Catania for the realization of numerous conferences on the theme “aesthetics of the front group” (ceramic veneers). He practices a free profession between Catania and Rome and collaborates as a scientific researcher with Prof. Dai Kawahara, director of dental materials at the University of Osaka. 

Abstract:

The therapy that we propose, unlike normal regenerative protocols, is a technique called SS fly, which unlike the Socket Shield consists of an autologous graft of the extracted root, appropriately processed out of the mouth and immediately re-implanted into the original site. With this technique we obtain positive results in the short term, with a very satisfactory medium-term maintenance that is very promising even in the long terms. Moreover thanks to the use of cono morse taper connection, which makes possible to decouple the prosthesis from the implant, we can control the position and, if necessary, adjust the structure from the third week after the insertion. The extraction and customisation of the root (out of the mouth) do not involve great technical difficulties and are very simple to carry out with the patient in the chair. In addition, no filler is required, but a simple provisional that acts as a camera and umbrella concept.

Title: Prevalence of Gingivitis and Periodontitis in Saudi adult male population and the ABO blood group distribution

Biography:

Mohammad Parvaiz Farshori,  working as an Assistant professor in department of physiology in college of medicine, and the coordinator of physiology program at college of in college of dentistry at university of Hail in Saudi Arabia. 

Abstract:

Many studies have reported a high prevalence of periodontal diseases among Saudi children and the male and female adult population. Saudi Arabia has a very high prevalence of obesity and diabetes. Many earlier studies have suggested about three fold increase in the incidences of periodontitis among diabetic patients. We recently reported a very high prevalence of periodontitis among the diabetic adult female patients. We found a significant increase in tooth loss and tooth decay among diabetic patients. In the recent past many studies have shown an association between the inheritances of blood groups with hypertension, cardiovascular disease, diabetes and many kinds of cancers.Although many studies have been published to report ABO blood group distributions among Saudi population but to the best of our knowledge to date no studies have been done to show an association between gingivitis and periodontitis and ABO blood groups. In the current study we wanted to analyze the possible association between the inheritance of ABO blood groups and the incidences of gingivitis and periodontitis among Saudi adult male population.Oral exams were performed by dental interns on a total of 400 randomly selected male subjects and their ABO blood group was recorded. Next we recruited 460 male subjects who either had gingivitis and or periodontitis and their ABO blood group information was recorded.  Their oral cavities were thoroughly examined for the presence of dental carries, gingivitis, periodontitis, and tooth decay and or tooth loss. Data was carefully recorded and analyzed.Our blood group distribution analysis of gingivitis and periodontitis patients showed 3.26% to be A-, 5.43% were A+, 2.82% were B-, 13.7% were B+. 3.04% were found to be AB- and 8.9% were AB+. O blood group was the most prevalent blood group with 8.04% were O- and 52.39% were O+. There is a significant increase in prevalence of periodontitis in male diabetic patients as compared to the control group.  Our results also show increased tooth loss among diabetics as compared to the control non diabetic patients. There was a significant decrease in prevalence of A blood group and a significant increase in distribution of O blood group among patients with gingivitis and or periodontitis.
