Summary:

The consequence of inappropriate post selection and/ or hasty insertion can result in tooth fracture and/or loss. It has been demonstrated that conical or parallel sided post design has a direct effect on root fracture during post insertion. However, during experimentation it became apparent that root size and its relationship to post size had a direct effect on root fracture. This article correlates root size, post size, and fracture rate during insertion of prefabricated posts.

Fifty Years of Interdisciplinary Site Development: Lessons & Guidelines from Periodontal Prosthesis
Just as "osseointegration" became synonymous with successful restoration of function in the fully edentulous patient during the 1980s, the term "implant site development" has become intricately associated in the 1990s with the techniques used to achieve esthetic results with implants in the partially edentulous patient. This article explores the roots of the concept of site development within the philosophy and principles of periodontal prosthesis. In addition, the myriad of techniques that are…

Timing of Loading and Effect of Micromotion on Bone

Timing of Loading and Effect of Micromotion on Bone
A significant no-load healing period is the generally accepted prerequisite for osseointegration in dental implantology. The aim of this article was to examine whether this no-load healing period is validated by the experimental literature. In vivo histological data was scrutinized to identify the effect of early loading protocols on the bone-implant interface. Several loading modes were identified. They were categorized into groups according to implant design and the type of prosthetic reconstruction,…

Immediate Fixed Rehabilitations with the use of Axial and Tilted Implants
During the last decades, materials and techniques have improved continuously and immediate loading has been revealed a predictable and reliable procedure, especially for full-arch rehabilitations. The aim of this webinar is to feature surgical of prosthetic aspect of immediate loading rehabilitations like All-on-4, V-II-V, Trans-sinus Tilted Implants and Zygoma Implants, thanks the resolutions of clinical cases. Successful long term outcomes could be achieved with a proper learning curve of the all dental team and with the use of high-quality materials.

Rehabilitation of the Extreme Atrophic Jaws
In this lecture you will learn several alternatives for the full arch rehabilitation of the jaws with different degrees of resorption. Several cases will be presented step-by-step with high-quality pictures for each technique explained. The main goals are to avoid complex regeneration procedures, to avoid zigomatic surgery and to still be able to perform immediate loading in the most compromised scenarios.All on Four technique, palatal approach technique, pterygoid implants and the most recent Subperiosteal Implants are some of the key-concepts presented.

The Role of Digital Technologies & Materials for Full-Arch Implant Reconstruction Premium Member Content

The Role of Digital Technologies & Materials for Full-Arch Implant Reconstruction
In prosthetic rehabilitations, we used for many years codified and widely described protocols in literature, with results that met our expectations and well above those of our patients. It is true that the advent of new technologies has enabled the dental team to use new material and new equipment that facilitated the production of an adaptation and an accuracy of the prosthetic rehabilitation that has, up to now, been difficult to obtain. In this presentation, we will analyze different cases, highlighting the operational differences that they have developed over time, with the increasing knowledge of the new materials and the daily developing of the new software's. It is also described how traditional materials and techniques have been replaced with other innovative new technologies, and how the results obtained with these are systematic and significantly better in updated generations prior.
