Influence of the macrodesign of an implant and the sleeve system on the accuracy of template-guided implant placement: A prospective clinical study.

Statement Of Problem: Three-dimensional (3D) implant planning facilitates determining the optimal position and number of implants, in terms of function and esthetics, by taking into account adjacent structures. Template-guided implant placement is an established procedure for implementing this planning, although the accuracy between the planned and the actual implant position is subject to many influences. The influences of the macrodesign of the implants and the sleeve materials used have rarely been investigated clinically.

Identity Leadership, Employee Burnout and the Mediating Role of Team Identification: Evidence from the Global Identity Leadership Development Project.

Do leaders who build a sense of shared social identity in their teams thereby protect them from the adverse effects of workplace stress? This is a question that the present paper explores by testing the hypothesis that identity leadership contributes to stronger team identification among employees and, through this, is associated with reduced burnout. We tested this model with unique datasets from the Global Identity Leadership Development (GILD) project with participants from all inhabited continents. We compared two datasets from 2016/2017 ( = 5290; 20 countries) and 2020/2021 ( = 7294; 28 countries) and found very similar levels of identity leadership, team identification and burnout across the five years.

A virtual clinical feasibility study for the indication of one-piece ceramic implants in the anterior maxilla.

Aim: One-piece ceramic implants (O-PCIs) have proven to be clinically useful, with high survival rates. The biocompatibility and bio-inert characteristics of ceramics in addition to the fact that minimal plaque deposits occur on these materials provide esthetic advantages and justification for their use in the anterior maxilla. The objective of the present study was to investigate the suitability of O-PCI use in the anterior maxilla.

Factors Influencing the Accuracy of Freehand Implant Placement: A Prospective Clinical Study.

(1) Background: The objective of implant prosthetic restoration is to ensure the best possible rehabilitation of function and esthetics. Optimal positioning of the implant with regard to the bone availability, surrounding soft tissue, and prosthetic sustainability should be strived for during implant placement. The factors influencing freehand implant placement and the accuracy achieved with this procedure are investigated in this prospective clinical study.
