The focus question was: “In immediately loaded dental implants, what are the effects of lower insertion torques compared to medium or higher insertion torques in terms of implant survival rate?” This question considered the following PECO (Stone, ²⁰⁰²) definitions:

The following secondary outcomes variables were considered: marginal bone levels changes (in mm); peri‐implant soft tissues changes (changes in the position of the mucosal margin); mechanical (failure of a prefabricated component caused by mechanical forces), technical (e.g., screw loosening, prostheses fracture, contouring adjustments), and biological complications (consisting of peri‐implantitis and peri‐implant mucositis).
