Clinical trials

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.

This multicenter randomized trial compares the clinical effectiveness of intraligamentary injection versus inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis in mandibular molars. The goal is to determine which technique provides better pain control during endodontic treatment.

This is a multicenter cross-sectional study that aims to provide a snapshot of the experience of patients before starting dental treatment.

The DS Prime Taper EV dental implant system was recently launched on the implant market by Dentsply Sirona (York, PA, USA). Dental implant systems are undergoing rapid evolution, ultimately driven by their broad therapeutic indications. As manufacturers strive to keep up with the demands of a growing market, designs are changing faster than clinical evaluation. This means that the time needed to assess medium- and long-term clinical outcomes before designs change again cannot be met. Clinicians need to have a "real" analysis of the clinical performance of implants before using them. Therefore, reporting of results is necessary to avoid use in patients without proper practical checks even before the recommended 10- and 15-year follow-up periods.

This is a randomized multicenter clinical study that compares two static guided surgery techniques in free-end partial edentulism. The aim is to compare the accuracy obtained between dento-osseous supported and dento-mucosal supported surgical splints to place dental implants in posterior osseous ridges.
