Abstract
Orthodontics & Periodontal tissues: biological aspects
Periodontology and Orthodontics are closely related disciplines. This is not only from a biological point of view, both dealing with the same tissue – the periodontium – but also in regards with the clinic: proper orthodontic treatment cannot be performed without a healthy periodontium, while improper orthodontic treatment may have detrimental consequences on the periodontal tissues. Among the possible adverse effects of orthodontic treatment on the periodontium regards recession development. The presentation will address the biological background of gingival recession development in relation to orthodontics.

Abstract
Orthodontics & Periodontal tissues: clinical aspects
Orthodontic tooth movement may support periodontal health through adaptation of alveolar bone and gingival tissues but can also worsen periodontal health in presence of active periodontal disease or under unfavorable anatomical conditions.
This lecture will cover the periodontic/orthodontic interrelation as regards periodontal osseous and soft tissue defects. The main part of the presentation will deal with four main questions on the influence of orthodontic treatment on the development of gingival recession: Does orthodontic tooth movement induce gingival recessions? Do orthodontically treated patients suffer in the long run more from gingival recessions compared to untreated individuals? Does prolonged fixed retention influence the development of gingival recessions? How can the periodontist assist in the prevention of development of gingival recessions? The understanding of the association between orthodontic tooth movement and development of gingival recessions is important because of the high number of children, teenagers and adults who are treated orthodontically.

Abstract
Orthodontic tooth movement in patients with a severe periodontal disease
A raising number of adult patients will seek dental care for esthetic reasons. Among which, patients with an advanced periodontal disease who might present a pathological tooth movement secondary to inflammation and bone loss. It is an undisputed fact that sound periodontal health is a prerequisite for successful orthodontic therapy, orthodontic treatment must be performed under stable and sound periodontal health alongside a strict hygiene regimen. Certain periodontal treatment modalities need to be undertaken before commencing orthodontic treatment. Some periodontal procedures are required after active orthodontic treatment.
This lecture will enlighten the biological limitation and clinical risks when considering orthodontic treatment in the periodontally compromised patient while proposing work protocols to overcome and prevent possible periodontal deterioration and biological side effects via case presentations.

Abstract
Management of Soft Tissue Defects Following Orthodontics
Orthodontic therapy of healthy young adults but also elderly patients is nowadays a routine clinical procedure. Moreover, orthodontic therapy is often integrated in the treatment of periodontitis, mostly following active periodontal therapy. However, several questions such as when and how to perform orthodontic therapy in periodontitis compromised patients, what are the mucogingival considerations to be taken into account in patients ungergoing orthodontic therapy are still open. The symposium will cover the most important biological and clinical aspects related to the interactions between orthodontic therapy and periodontal tissues and provide the clinician with the rationale on when and how to integrate orthodontics in the treatment of periodontally compromised patients. The mucogingival aspects to be considered before and after active orthodontic therapy, along with treatment recommendations will be also addressed in detail.

Abstract
Clinical concepts and new developments in reconstructive periodontal surgery
Reconstructive procedures in periodontology aim at regenerating the lost periodontal supporting tissues which have been lost following periodontal disease. During the last decades, several treatment modalities including the use of bone grafting materials, barrier membranes, enamel matrix derivative (EMD), some types of growth factors or various combinations thereof, have been shown to promote periodontal regeneration (i.e. formation of cementum, periodontal ligament, alveolar bone and gingiva) to a varying extent.
In recent years, a better understanding of the biology, combined with improved surgical techniques yielded to clinical concepts enabling predictable treatment outcomes in intrabony, furcation, and also recession-type defects. In carefully selected patients and defects, in conjunction with a strict pre -and postoperative infection control, reconstructive periodontal surgery may lead to substantial regeneration of hard and soft tissues and clinical benefits evidenced by probing depth reduction, gain of clinical attachment, defect fill and improved esthetic outcomes. Moreover, longitudinal studies have also provided evidence for long-term stability of the clinical outcomes, thus pointing to the clinical relevance of these concepts in improving tooth prognosis. Very recently, new formulations of EMD such as Osteogain combined with various types of bone grafting materials or collagen matrices have been shown to positively influence periodontal wound healing/regeneration.
In the last years, the use of innovative surgical techniques such as the Modified Coronally Advanced Tunnel (MCAT) or the Laterally Moved Tunnel (LMT) combined with connective tissue grafts or collagen matrices with or without EMD have been successfully integrated in the overall treatment concept providing predictable clinical outcomes with ling-term stability.
The present lecture will provide the scientific background for a biologically driven philosophy in reconstructive periodontal surgery while presentations of clinical cases and of surgical videos will demonstrate the step-by- step procedure of these concepts in various clinical scenarios.

Abstract
Modern Clinical Dilemma: Implants vs. Endodontics
Dental implants has become an integral part in modern dentistry since late 1980.  Original true indications for dental implants included the replacement of single missing teeth or in partially and completely edentulous situations.  Nowadays it is very different. Some clinicians even suggest the extraction of teeth that could be saved by root canal therapy and prosthetic reconstruction, as implant treatment is believed to be more predictable. This predictability is based on the reported high success rates for endosseous implants in literature.  Is it true?  
The dilemma for many clinicians, especially general dentists, is when to treat a tooth endodontically and save it or extract it and subsequently placing an implant. It is not an easy decision for many situations.
In this presentation modern endodontic therapy, both nonsurgical and surgical treatments, will be discussed along with true success or survival rate of implants.
In conclusion, participants should be able to compare endodontic and implant studies according to success and survival rates, understand the importance of an interdisciplinary treatment planning approach and be able to make an educated decision whether to endodontically treat a tooth or extract and place an implant.

He has been honorary professor at the Ukrainian Academy of Medical Stomatology since 2006 and member of the most eminent international scientific associations in the field of Restorative Dentistry and Adhesive Prosthodontics. Over the years, he has been practicing very high-level clinical activities, together with his own clinical Staff, setting-up within the University of Chieti one of the worldwide most advanced center in the field of Restorative Dentistry, Adhesive Prosthodontics and Occlusal Problems. In parallel with the clinical activities, at the University of Chieti he coordinates a dynamic research group, that has become over the years a reference point in Europe for the biomechanical studies on dental materials employed in Restorative Dentistry and Adhesive Prosthodontics and is particularly interested in the materials to be used for the full mouth rehabilitation of patients with parafunctions or TMJ disorders. His clinical and scientific knowledges about the problems, the procedures and the materials related to the oral rehabilitation of parafunctional and dysfunctional patients led to the publication of a textbook titled “E.F.P. (Esthetical-Functional-Postural) Clinical Approach” (ACME edition), together with Dr. Lorenzo Vanini. He is also author of another very successful volume published together with Macij Zarow, Gaetano Paolone, Gianluca Paniz and Luis Felippe translated in English, Polish, Russian and Portuguese: “Endoprotesica” Ed. Quintessence. He published more than 100 papers on the most prestigious national and international journals .

Abstract
Esthetical-Functional-Postural (E.F.P.) rehabilitation using Additive solutions: the new challenge of prosthetic dentistry
Using EFP approach excelent esthetic results may be obtained, saving the occlusal balance or, in case of parafunctional patients, improving the occlusal balance. In other words today it is possible to improve smile, occlusion and posture of the patient with one single treatment.
Adhesive Techniques have completely changed the clininical approach and procedures in dentistry, specially in prosthodontics.
Today thanks to these techniques “ADDITIVE SOLUTIONS” have been made available, that means in most cases the sacrifice of sound tissues is not necessary to successfully restore teeth.  With traditional procedures we usually use “RESETTIVE SOLUTIONS” , as to place the restoration the remotion of sound enamel and dentin is always needed.
 It is a matter of fact that adhesive materials and techniques have made it simple to reach amazing esthetic results using not invasive procedures. Today it is similarly easy to reach the same results  also in occlusal rehabilitation using the same materials and techniques.
During the lecture the step by step procedures to evaluate the patient occlusion and to restore a right esthetic smile will be shown. Moreover  procedures for full mounth rehabilitation of parafunctionl patients using an additive prosthetic approach will be described.
Finally the properties of adhesive materials and the criteria for a proper material selection in each specific clinical case will be analyzed.

Abstract
All-on-4® Treatment Concept - Clinical application in daily practice
Edentulous patients wishing fixed prosthetic rehabilitation are very often faced with time consuming, expensive and painful bone grafting procedures. The application of graftless solutions has dramatically improved the patient acceptance rate.
The All-on-4® treatment concept provides a graftless and advantageous solution for delivery of full arch immediate load prosthesis for total edentulous or failing dentition patients. The rehabilitation over implants with immediate function is a challenging procedure, demanding not only immediate outcomes but also long-term success. Due to its high level of demand, this type of rehabilitation requires a multidisciplinary approach, focusing not only on the surgeon or on the prosthodontist, but also demanding the involvement of an entire team of professionals.
This lecture mainly focuses on the treatment planning and workflow of rehabilitation over implants with immediate function through the MALO CLINIC Protocol. The biomechanical basis and clinical success of the All-on-4® treatment concept in both maxillary and mandibular arches has been validated by numerous scientific and clinical publications in the dental literature.

Abstract
 The Socket Chamber Concept: Clinical Outcomes of Immediate Implant Placement and Restoration
 An immediate implant placement has to be combined with a primary wound healing of the extraction socket by a seal with a root-shaped abutment/crown complex. The resulting socket chamber is filled with blood which has a very high potential for healing and for new bone formation. The blood-filled chamber completely ossified without any therapeutic support [1] - the placement of membranes and bone replacement materials in case of a lack of buccal bone lamella loses its dogmatic required application [2]. This kind of immediate restoration simulates a tooth-reimplantation in the transition zone requiring a flapless tooth extraction. It ensures the preservation of the original emergence profile including papillae and long-term esthetics [3]. However, an appropriate implant thread design and osteotomy is mandatory to gain predictable a sufficient primary and secondary stability of the implant at the fresh extraction socket. Additionally a two appointments work-flow enables an one-abutment-one-time [4] concept preventing mid-facial soft-tissue recession.

Abstract
Principles of Hard Tissue Grafting
Autogenous Bone graft is still the gold standard for the reconstruction of severe atrophy of the maxilla or the mandible. Two & 3 dimensional bony defects need for the reconstruction special surgical procedures with autogenous bone grafts to assure at long term an acceptable functional and esthetical result. Biomaterials have here their limitation and are for such reconstruction until today not an alternative due to their poor regeneration potential.
Autogenous bone graft harvested from intraoral sites, especially the retromolar area of the mandible, and used following the split bone block (SBB) technique is offering many possibilities for intra operative facilities and stable long term results. Splitting the thick cortical block to 2 or 3 thin blocks is augmenting the number of blocks allowing the reconstruction of larger atrophic crest and giving a better adaptation to the recipient site with individual determination of the width and the volume of the grafted area. Filling the space and gaps between the thin block and the remaining crest with particulate bone chips is reducing the time needed for revascularization of the graft improving its vitality compared to the original thick block.  
Many studies demonstrate that the reconstruction of horizontal and vertical atrophied crest with thin mandibular blocks in combination with particulate bone grafts, without any biomaterial or membrane, offer over years, through the high vitality of the grafted and regenerated bone, a stable periimplant bone level. Implants inserted in this grafted bone presented similar osseointegration as implants placed in non grafted bone.

Learning objectives:
This presentation describes practical aspects and results of those techniques that make possible long-term esthetic and functional implant restorations:   
-    Diagnostic, alternatives and decision
-    Technique of safe harvesting of bone blocks
-    Technique of block grafting (SBB technique and biological concept)
-    3D reconstructions
-    Soft tissue management for graft protection and soft tissue augmentation

Abstract
Prevention of the complications in Implant dentistry : the Human Factors Concept
Placing dental implants and providing implant-supported prostheses are governed by procedures that are set down in minute detail. Nonetheless, dental practitioners continue to face complications in their day-to-day working practice. Studies carried out on Human Factors - initially developed in the aviation industry and then applied to the world of medicine – demonstrate that in both medicine and dentistry, the environment in which practitioners work has a massive bearing on the likelihood of complications arising. Different factors such as fatigue, time constraints and poor team communication can all have a negative impact upon the operational effectiveness of the practitioner and their team. Moreover, several scientific studies have shown that excess stress is the single factor most likely to influence the decision-making process during dental or medical procedures. It is therefore important to employ the simplest protocols possible – as long as these protocols deliver long-term results that are comparable with those achieved using more complex procedures.

8. John Besford

CV
John Besford qualified as a dentist in 1964 (BDS, Manchester University, UK) and retired from clinical practice in 2012. In between those dates he did research in bacteriology (PhD 1970, Manchester University, UK), lectured in removable prosthodontics at London University for 29 years, ran a specialist private practice in removable and implant-stabilised prosthetics in Central London for 25 years, and has been an invited freelance postgraduate lecturer worldwide for the last 40 years. He has designed award-winning denture teeth and has his own small Besford Study Club. Removable prosthodontics has been his vocation and delight. He believes that natural teeth are much better than dental implants and that dentures should look like natural teeth and gums.

Abstract
Removable dentures that make people feel better and more like themselves
In dental æsthetics two opposing visions fight each other – idealism versus realism. Idealism is easier and quicker and more profitable. Realism requires more skill and time, but heals the human spirit more.
Idealist dentists and patients aspire to dental appearances of a classical perfection: juvenile and characterless ‘nobody-in-particular’ dentitions, not related to the age and face of the individual patient. Perfectionist orthodontics can make natural teeth look like artificial dentures. In prosthodontics, idealism can cause fixed or removable prostheses to look like dentures, too. These results, while sometimes beautiful, always look unreal – ‘too good to be true’ – and thus they violate the patient’s ‘prosthodontic privacy’.
Realist dentists and patients aim at naturalness and individuality; they work together in the clinic, from individual evidence such as photographs rather than from unnatural stereotypes already implanted in the mind. The denture creation process is experienced by the patient as personal, involving and caring. The results are a) biographical – ‘how I would have looked if this terrible tooth loss hadn’t happened’, – b) normal-looking (so they switch off the social observer’s attention), c) more stable because the teeth are in their original natural positions and d) inspire greater self-confidence because they look and feel more real. The morale of the patient is restored at the same time as the dentition. The morale of the clinical team experiences an upswing, too.

Abstract
Optimizing Soft and Hard Tissue
The aesthetic zone provides the most challenging issues when dealing with and soft tissue development. Bone augmentation techniques and soft tissue grafting are more often needed in order to achieve excellent aesthetic outcomes. This lecture will cover numerous aspects involved in the creation of ideal bone and soft tissue to ensure outstanding long term aesthetic stability.
