Nowadays the evolution of toxicology knowledge of metals has put the issue of prosthetic metals at the forefront of the news. Ionic migrations from dental prostheses is a clinical reality, but little importance is given to this phenomenon despite the iatrogenic effects that may result. The release of metal ions inside the oral cavity following the phenomena of galvanic corrosion can disrupt the neuro-vegetative systems of our patients or even selectively block certain so-called metallo-enzymes enzymes governing their cellular processes. The purpose of this work is to illustrate a holistic approach to dental management combining biomimicry and electro-magnetic balance to serve the overall health of our patients.

Progress in the field of biomaterials and the evolution of collage techniques have allowed practitioners to develop adhesive dentistry that aims to sustainably rehabilitate the teeth cut to a minimum and can meet the aesthetic demand of our patients with reliable treatments namely indirect partial aesthetic restorations. The choice of this type of fixed rehabilitations is all the more justified by a greater sustainability of indirect restorations by contribution to direct fillings. However, the use of metal alloys as amalgam-type or indirect indirect filling is still in common use in some countries. The objective of this work is to illustrate via a reliable and simple clinical approach the service that we can offer to our patients by realizing onlays onlays aesthetics respecting the structure, the biomemitism but especially the therapeutic gradient.

After conquering the world of the fixed prosthesis, the digital impression opened to the prosthesis, orthodontics and implantology. Certainly its benefit is present if only for the treatment of the imprint and its archiving, but the concept of evidence-based medicine is broader than that. Several clinical studies have focused on the study of the comparison between optical and conventional impressions, but only a small number of publications reflect a critical analysis of the literature, namely the randomized controlled clinical trials nowadays corresponding to gold standard in terms of level of evidence and systematic quantitative reviews and meta-analyzes of these tests. Within the fixed prosthesis department, we are equipped with a machining machine and in order to make our workflow totally digital, we wonder about the usefulness of introducing the optical impression in our practice. This work was organized in four parts according to the IMRAD structure (introduction, materials and methods, results and discussion). This is a systematic review of randomized, quasi-randomized controlled trials conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes) criteria and the articles were analyzed according to the PICO model (Patient / Problem, Intervention, Comparison and Outcome).

The absence of the superior lateral incisor (agenesis, trauma, caries, periodontal disease) is problematic towards the therapeutic decision, which is often multidisciplinary. The choice of the appropriate treatment plan depends mainly on the availability of the space of this tooth on the arch. So we will have mainly 3 options: - To open the space by an orthodontic treatment before the prosthetic rehabilitation (implant, bridge ..) - Or to close the space by orthodontic traction of the canine that will undergo a modification by subtraction or coronoplasty to simulate the anatomy of a lateral incisor. - Or even to abstain when it comes to symmetrical bilateral absence that does not affect the aesthetics of the individual. This review of the literature summarizes possible approaches to replace the upper lateral incisor and the decision factors of these therapeutic approaches.

Nowadays the use of metals or even amalgam in dentistry is still relevant in some countries. These materials, widely used for making crowns and bridges placed in the mouths of our patients, are responsible for local and general adverse effects. In order to respect the principles of energetic dentistry and to meet the esthetic expectations of patients of our time, all-ceramic rehabilitations must be included in the therapeutic arsenal of any practitioner concerned with preserving the overall health of his patient. The aim of this work is to illustrate a modern clinical and technical decision-making approach, respecting the illusion of the natural and the morpho-functional project in order to achieve a fixed prosthetic rehabilitation looking for the fusion between neuro-musculo-articular balance, equilibrium smile and overall health of the patient.
