Clinical Science and Techniques

Background: It has previously been demonstrated that immediate full occlusal loading of freestanding anterior implants can be performed using cortical satellite implants, obtaining a success rate similar to conventional protocols. The aim of this report was to present the outcomes after 36 months after initial placement.

Methods: Twenty patients received 2 single-standing titanium screw implants, which were stabilized during healing time with cortical satellite implants. Immediately after surgery, mandibular overdentures were placed using ball attachments. The satellite implants were removed after 3 months.

Results: Implant survival analysis showed a 100% success rate. The following parameters were assessed during the study: Periotest values, −5.89 (minimum: −7.00, maximum: −4.00); radiographic assessment of bone resorption, 0.51 mm (minimum: 0.00 mm, maximum: 1.50 mm); and pocket probing depth, 2.60 mm (minimum: 1.00 mm, maximum: 8.00 mm).

Conclusions: The results suggest that immediate loading of freestanding implants stabilized with satellite implants is a successful concept at 3 years observation time.
