About this trial
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.
Eligibility criteria
Qualifiers
Adults aged 18 years or older.
Indication for a single implant-supported restoration.
Good general health and absence of active periodontal disease.
Willingness to provide written informed consent and to undergo two intraoral scans (immediately after implant placement - T0 - and before prosthetic loading - T1).
Disqualifiers
Uncontrolled systemic disease or any medical condition contraindicating implant surgery.
High-risk antiresorptive therapy (e.g., intravenous bisphosphonates or denosumab).
Pregnancy or breastfeeding, if applicable to local policy.
Inability to attend the T1 follow-up visit or contraindication to intraoral scanning (e.g., limited mouth opening, severe gag reflex).
