The desire for immediate load restoration of dental implants, particularly in the anterior esthetic zone, requires specific implant design strategies to enhance primary stability. In the presence of extraction sites, often with compromised bone, implant fixation is obtained apically and palatally. Surface roughness is a factor in early osseointegration (Alberktsson et al. ). However, it is the macro-architectural design of the implant that establishes initial mechanical fixation, which is crucial in minimizing implant mobility in the first 3–4 weeks of function. In the search of a new macro-architectural design, an idea of adding a wing to the implant for extra primary stability was raised. Finite element analysis of the ‘winged’ implant, in comparison to a regular implant, revealed that when a 20 kg force is applied at an off-axis angle of 20°, the amount of maximal displacement at the neck of a regular implant is 60% higher than observed with the ‘winged’. In order to determine the clinical efficacy of this new implant, a study was undertaken to evaluate the implant in both jaws under conditions of immediate function. This implant will be presented with finite elements analysis and animal experiments with explanation of the biomechanics of pri-implantitis.
