Abstract [eng] Advancements in technology are reshaping the landscape of dentistry and medicine, with the rapid integration of cutting-edge innovations into clinical practice. The synergy of surgical and prosthetic phases in dental implantation is explored in this study, with a focus on the latest technologies and materials. Precise 3D positioning of dental implants and the selection of appropriate prosthetic materials are identified as pivotal elements in ensuring patient safety and achieving optimal functional and aesthetic outcomes. In the first part of this research, the accuracy of digitally planned dental implantation was assessed using intraoral scanning method, measuring the insertion point (3D), actual and absolute depth, horizontal and angular errors. Static and dynamic navigation methods were explored, along with the influence of edentulous defect configuration (Kennedy class), implant design, position, and the reference objects for dynamic navigation. In the second part, materials used in immediate dental implant prosthetics and their biocompatibility were investigated. Surface roughness, hydrophilicity (water contact angle), and the response of human gingival cells were assessed. Evaluation encompassed five polymeric materials, including innovative options such as polyetherketoneketone (PEKK) and 3D-printed polymethylmethacrylate (PMMA), while also exploring the effects of surface cleaning. Furthermore, five ceramic materials were compared, and the influence of UV radiation activation on zirconium oxide ceramics was investigated. This study significantly contributes to the understanding of the accuracy of dental implantation navigation methods and the biocompatibility of immediate prosthetic materials, further advancing the fields of implant dentistry and prosthodontics.
