Introduction: Implant-supported prostheses are an excellent treatment option for totally edentulous patients, however, some conditions, such as extremely atrophic jaws, may limit their application. Aims: to demonstrate and discuss, through a series of clinical cases, the functional aesthetic resolution of totally edentulous patients with atrophic maxillae, using three different implant-prosthesis approach. Methods and Material: This article describes a clinical case series of patients has between 65 and 75 years old, who lost all upper teeth and had severely atrophic jaws. Due to the bone situation of the maxilla, an osteotome was planned for sinus floor elevation and followed by an allogeneic bone graft. After 18 months of bone integration, osseointegrated implants were installed and different prostheses were made for each case. Conclusions: It is possible to conclude that with the use of advanced surgical and prosthetic planning it is possible to recover the aesthetics and function of a serious and complex clinical case.

Introduction: In the decades with the advancement of materials fabrication, such as restorations with the latest improvements in their dental fabrication process, or as restorations with improvements in their dental fabrication process, or as the latest restorations in their dental fabrication process, dentistry, or as the latest restorations in their restorative materials manufacturing process. Objective: This work aims to demonstrate through a literature review the use of the endocrown technique. Methods: The research was carried out from January to May 2022 and was developed based on PubMed, Scielo, and Google Scholar. Results: There were 11 a total of 13 articles on Endocrowns. In total, 47 articles were complete and 19 were included in this study. Dentistry, contributing to a better resolution of cases, presents little interocclusal space, so the indirect endocrown restoration technique becomes an excellent option, presenting a good alternative and less dental wear for making. Conclusion: It was concluded that the use of the endocrown technique has shown, for the most part, employing clinical results that it is an excellent restorative option for the restoration of molars with great coronary destruction, and its clinical survival rate was comparable to the use of intraradicular posts of fiber.
