Due to their chemical, physical and bioactive properties, tricalcium silicates are now considered as the materials of choice for vital pulp therapy. In addition to the hermetic seal, they provide once applied onto the pulp, an anti-inflammatory potential which creates the adequate conditions for dentin-pulp regeneration and successful clinical outcome. Moreover, the recently demonstrated pulp capacity to kill cariogenic bacteria, contributes to our understanding of the materials successful use in irreversible pulpitis treatment.

This presentation will demonstrate the pulp regeneration potential and its capacity to kill cariogenic bacteria. It will explain the main tricalcium silicates properties and report recent data on their anti-inflammatory potential. This lecture will also demonstrate that adding resins to tricalcium silicate alters their bioactive properties.

An ideal restorative material should not only be biocompatible, mechanically resistant and aesthetically pleasing but also demonstrate spontaneous and long-term strong adhesion to dental tissues, bulk-fill properties and bioactivity. After resin-modified glass ionomers, compomers and giomer, new hybrid or bioactive materials have been introduced. What do we know about their chemical reaction? What are theirs adhesive, mechanical and biological properties? How can we classify them for a suitable clinical use?

Minimal intervention dentistry is now accepted for caries management. How and when to intervene using non-invasive, micro-invasive and invasive techniques according to the patient's individual caries risk and the caries activity are the main factor. First, at each treatment steps: Non-Invasive, Micro-Invasive, or Invasive, it raised questions about how to clean without damaging, how to disinfect the deep dentine layers, when to promote the use of ions released biomaterials. Second, the new diagnostic technologies combining images, magnification, and photonic signals like fluorescence, Infrared and photothermal radiometry completely modified the paradigms of the Minimally Invasive Dentistry and caries diagnosis. The presence of surface cavitation is the starting point for micro-invasive restoration, caries activity is a warning sign to reverse or to moderate the caries process thanks to ions released biomaterials and cleanability is a moderating factor. The objective learning of this lecture will discuss the commercially available technologies for carious lesion detection, with an unconventional angle, to determine how these devices can help us to interpret the clinical situation: lesion cavitation, activity and cleanability and shift the line of the academic cariological engrams.

Lithiumsilicate based ceramics exhibit superior strength and toughness than feldspathic or leucite reinforced dental ceramics, being thus preferred materials for the fabrication of single-unit as well as anterior three-unit dental prostheses. Consequently, a variety of new materials recently entered the market. Processing strategies thereby involve one versus two step and chairside versus labside approaches. Established heat pressing of fully crystallized lithium silicate ingots is as popular as CAD/CAM machining of restorations from either fully or partially crystallized blocks, with the latter one followed by a final crystallization step.

This talk will provide fundamentals of glass ceramic processing and specifications of lithium silicate chemistry and crystallization kinetics. It will further provide the background in crystallite reinforcement resulting in improved strength and toughness. Microstructural peculiarities will be discussed as well as the practical impact of the microstructure. Different crystal phases and their effect on residual stress build-up will be addressed on the basis of thermal expansion theory.

The continuous improvement of the digital CAD-CAM technology is revolutionizing the dental profession in both laboratory and dental office. Today it is possible with the chair-side CAD-CAM restorations to restore teeth in a single session saving time for the patient and dentist as well.

Numerous types of glass ceramic and composite block are nowadays available; partial and full crown restorations can be fabricated directly in dental office by the dentist. However, it is vital that the treating clinician have a thorough understanding of the principles that lead to a successful outcome. Naturally appearing and problem free outcome can be achieved if certain rules are followed by a conscientious operator.

Dr. Roberto Spreafico obtained his DM degree at Turin University, Italy, in 1982. In 1986, he obtained a DMD degree, at Geneva University, School of Dentistry, Switzerland. He is now a private practitioner, in Busto-Arsizio, near Milan, Italy and an Honorary Professor, University of Buenos Aires, Argentina.

He is active member of Accademia Italiana di Conservativa, European Academy of Esthetic Dentistry. Founder and active member of Italian Academy of Esthetic Dentistry. Founder of Digital Dental Academy, Founder of International Academy for Digital Dental Medicine. Associate Editor of “International Journal of Esthetic Dentistry”.

Dr Spreafico presently conducts a number of courses in the field of esthetic dentistry throughout Italy and abroad. He is also author of numerous clinical papers on this topic. Author of 16 book chapters in the field of restorative and esthetic dentistry. He co-authored the book ”Adhesive Metal-Free Restorations: current concepts for the esthetic treatment of posterior teeth.” by Quintessence Publishing Group in 1997.

Complex cases with high esthetic needs represent a challenge for clinicians. The Full Mouth Adhesive Rehabilitations (FMAR) represent the highest expression of adhesive restorative dentistry and allow aesthetic and functional rehabilitation of the arches with a minimally invasive approach with maximum respect for residual healthy tissues, avoiding unnecessary endodontic treatments and invasive preparations for complete crowns. Adhesion has completely changed the border between conservative and prostheses.

We can use a direct or indirect approach. The operative sequence involves an intra- and extra-oral aesthetic analysis with photos and videos. The digital preview, by Digital Smile Design, guides the first aesthetic wax-up, followed by the partial or full mouth wax-up with an increase (when necessary) of the Occlusal Vertical Dimension in order to create space for restorations with minimal dental preparation. The direct full mouth adhesive resin mock-up performed by silicon indexes, allow a clinical preview. The new temporary rehabilitation is tested from an aesthetic, functional and phonetic point of view for at least 1 months.

In some cases, it is possible to perform complete or partial rehabilitations of the arches with direct composite restorations free hand, pressed by means of silicon indexes or even with an Injection Molding technique using high filled flowable composite with an additive and non-invasive approach. The most predictable definitive rehabilitation, however, involves indirect restorations performed with heated-pressed or Cad-Cam Lithium Disilicate (or composite) overlays, quadrant by quadrant: first the lower and upper posterior teeth, then the anterior sectors with laminate veneers (palatal and buccal) or full veneers. An impressive final video will summarize all the clinical phases about FMAR.

Patients with progressed stages of tooth wear are often advised a restorative treatment including increased vertical dimension and full rehabilitation. However, many of those patients do not have an actual demand for help and moreover, due to the high-risk profile of those patients, restorative treatments may have a limited longevity. In the Radboud Tooth Wear Project referred patients with severe wear are included in order to decide which treatment is the best option. In situations where an instant treatment request by the patient is absent, patients will be managed by monitoring and counseling. When deciding a restorative treatment, there are several options: 1) direct composite resin restorations, 2) traditional indirect composite resin or ceramic restorations, 3) 3D CAD CAM indirect restorations. This lecture will help you to identify relevant risk factors in patient with severe tooth wear and will provide you a clear guideline for the management of these patients.

Dr. Bas Loomans graduated as a dentist in 1999 at the University of Nijmegen, the Netherlands. In 2000 he started his PhD-program in the department on the topic how to reconstruct proximal contacts with composite resin. In 2007 he finished his PhD with his thesis “Proximal contact tightness of posterior composite resin restorations”. In 2008 he was a visiting researcher at BIOMAT, KU Leuven, Belgium. At this moment, he is assistant professor at the Radboud university medical center and project leader of the clinical research project ‘Radboud Tooth Wear Project’ in which the aetiology, management and restorative treatment of severe tooth wear is investigated. Moreover, he is involved with student education, post-graduate courses for dentists, is supervising PhD-students on the topics of severe tooth wear and self-healing composite materials. He published 55 international publications and is (co-) author of several books. Besides he is working two days a week in a general / referral dental practice. His main interests are adhesive and reconstructive dentistry using composite resin restorations in patients with severe tooth wear, amelogenesis imperfecta and lip/palate clefts.

During the presentation, classification, indications and several keys will be given for the selection of composites and ceramics as restorative materials in conservative dentistry. Also the synergy and interaction among the conservative dentistry and the rest of dental disciplines, specially with orthodontics. They will be shown some of the benefits that can be provided to the patient through the combined treatment of the different areas and how the orthodontist can help the restorative dentist to solve some different treatment situatons in a conservative way and also how the conservative dentistry can help the orthodontist.

Dental adhesive materials have improved considerably over the last ten years, although shortcomings such as post-operative sensitivity, premature reductions in bond strength, interface and marginal degradation, and biocompatibility are still considered important issues with such materials. The degradation of the bonding interface occurs through two main mechanisms: the enzymatic degradation of its collagen fibrils, hydrolysis and leaching of resin monomers. Indeed, endogenous dentinal enzymes, such as the matrix metalloproteinases (MMPs) and cysteine cathepsins are activate in presence of water and these can degrade the denuded collagen matrix within the hybrid layer (HL). Moreover, hydrolysis of polymers within the hybrid layer is also a major factor thought to destabilise the resin-dentine interface. Strategies for the preservation of the HL over time have been developed, and they entail the removal of the unbound water from the gaps between the collagen fibrils as well as different modes of silencing endogenous enzymatic activity; these processes will be discussed during the lecture. Moreover, it will be also highlighted how “smart” ion-releasing resin-based materials biointeract with dental hard tissues and reduce the degradation of the resin-dentine interface via remineralisation of the mineral-depleted dental hard tissues, so improving the durability of resin-dentine bonds. Moreover, as the resin-dentine interfaces produced by contemporary adhesives are characterised by low mechanical properties, alternative “smart” bonding approaches may also contribute to strengthening of hybrid layers, producing more gradual gradients of stiffness that prevents localized stress concentrations. Thus, this lecture will attempt to bring together a number of seemingly unrelated events, to show how they may contribute to improvements in the durability of resin-dentine bonds and have a therapeutic role in the prevention of secondary caries.

A key to successful application of Free-Hand Bonding, alike to any other restorative project, is a detailed but proportionate treatment planning approach. As for function and biology, there is realistically no standardized esthetic diagnosis protocol. Then, depending on the extent of form or dimension/proportions enhancements, the selective use of different analog or digital tools will allow the clinician to create a precise esthetic project. Available methods include, individually or simultaneously, the use of a caliper, 2D imaging with lines drawn over the smile within Power Point or keynote software, the use of digital templates (only lines of full tooth rendering) and finally 3D imaging. In addition, a wax-up and mock-up can be used to foresee extra- or intra-orally the new smile configuration in advanced cases.
