Movement of Dental Implants During Osseointegration

Prospective multicenter observational study assessing whether dental implants undergo three-dimensional positional change between placement (T0) and pre-loading after osseointegration (T1). Two intraoral scans (STL) will be superimposed to quantify linear (mm) and angular (degrees) displacement. Clinical variables include insertion torque, primary and secondary ISQ, anatomical site, placement timing, operator-perceived bone density (Lekholm \& Zarb), bruxism, and night guard use. The primary endpoint is the 3D displacement at \~3-4 months. Multivariable analyses will explore associated factors.
