Non-Carious Tooth Surface Loss (NCTSL) is considered as a current issue of concern. It's management is challenging. Through this paper, the focus will be put on the different forms, locations and causes. Emphasis is placed on the importance of a thorough examination and indexing to assess the severity of tooth wear.A systematic and integrated approach leads to favorable and predictable prognosis. We aim to provide clear recommendations on the best treatment strategy and simplified guidelines to succeed tooth wear management? considering the patient's expectations, the esthetic demand as well as the risk profile.The patient should be fully informed. Restoration of severe tooth wear should ideally be delayed as long as possible.The different treatment modalities will be discussed according to the localization and the severity of tooth wear.The conservative, minimally invasive restoration, should first be considered.

One of the basic principles of tooth preparation for fixed prosthodontics is conservation of tooth structure. This is the major advantage of bonded bridge as an alternative to implant retained restorations in the esthetic zone. Especially used for juvenile patient who do not come into consideration for implant therapy?. This article describes the use of an all ceramic resin-bonded bridge as a conservative and esthetic solution for the replacement of 2 mandibular incisors for a 17-year female patient.

Purpose: To assess the 3-year survival rates and the incidences of biological and technical complications of all-ceramic and metal-ceramic tooth-supported single crowns. Material and methods: An online research of literature on Pubmed was conducted independently by 3 reviewers to identify the clinical studies performed from 2000 up to 2017 and completed by a manual research. Keywords, inclusion and exclusion criteria were well-defined. Results: The research revealed 501 titles and led to a final analysis of 31 full text articles. Only 6 studies met the inclusion criteria and reported on 215 metal-ceramic and 501 all-ceramic TSSCs. The meta-analysis of the included studies indicated an estimated survival rate of metal-ceramic TSSCs of 90.14% (95% CI: 89.72%-91.35%) after 3 years. This was a little bit higher than the estimated 3-year survival rate of Lithium-disilicate (89.54%; 95% CI: 87.18%-91.89%). However the 3-year survival rate, of Zirconia TSSCs was statistically much higher (92.01%; 95% CI: 89.58-94.43%). When the outcomes in anterior and posterior regions were compared, Zirconia and Lithium-disilicate TSSCs exhibited survival rates of 91.64% and 91.12% respectively, in the posterior region, where metal-ceramic TSSCs exhibited only 90.14% as a 3-year survival rate. As for the anterior region, we could only compare the TSSCs made out of Lithium-disilicate and Zirconia as the metal-ceramic ones were all laid on the posterior regions. Zirconia performed the highest 3-year survival rate in the anterior region (93.54%; 95% CI: 91.08-96%) whereas Lithium-disilicate showed only 87.5%. This was due to the low level of the mechanical properties of such material, which clinically indicated by major chipping and tooth fracture. Conclusion: Survival rates of metal-ceramic crowns were nearly similar to those reported for most types of all-ceramic TSSCs in the posterior region. Weaker Lithium-disilicate-based ceramics should be limited to application in the anterior region, even if they expressed a higher survival rate in the anterior regions. Zirconia-based TSSCs should not be considered as a primary option due to their high incidence of technical problems.

The aim of this article is to show the interest of minimally invasive restorations (ceramic veneers and lithium disilicate full coverage crown) to restore the appearance of discoloured, fractured teeth or teeth with diastemas providing esthetic results and solving problems related to the size, shape, and color of the anterior upper teeth. For this purpose, a correct diagnosis, careful treatment plan, clinical and laboratory procedures offered a satisfying esthetic outcome. Moreover, digital design can be used to enhance the final result since it offers a better predictability of the proposed treatment and facilitates communication with patient. It can be concluded that lithium disilicate restoration is a predictable and long lasting treatment option with which not only esthetics but also the strength and function of teeth can be re-established. The objective of this case report is to highlight the steps in dental rehabilitation using ceramic veneers reinforced by lithium disilicate. The objective of this case report is to describe all steps of dental rehabilitation using ceramic restorations reinforced by lithium disilicate.
