ROE Dental Laboratory has launched Passivity Plus, an FDA 510(k)-cleared self-adjusting titanium coping designed for full-arch implant restorations. According to the company, the four-component device is compatible with most major multi-unit abutment systems and is intended to address fit discrepancies that can occur during digital and analog restorative workflows.
According to the company, minor dimensional errors introduced through scanning, milling, sintering, and model fabrication can accumulate during the fabrication process and create chronic biomechanical stress on implants and prostheses when seated. The company said those stresses are associated with complications including screw loosening, prosthesis fracture, and peri-implant bone loss.
Passivity Plus, which features the NikolasBase, uses a pivotable self-adjusting cap designed to micro-adjust during seating to accommodate discrepancies. According to the company, once the prosthesis is positioned, a conical screw with a 5-degree-per-side body taper is torqued to 25 N•cm to create a friction-locked, cold-welded connection. The system also includes a flexible washer around the screw head intended to preserve the compensated position without transferring stress to surrounding structures.
“Passivity Plus truly elevates existing clinical passivity to a new level,” said BJ Kowalski, CEO of ROE Dental Laboratory. “Even restorations from the most accurate clinical records can benefit from Passivity Plus. It really helps relieve the stress of full-arch.”
According to the company, clinicians can incorporate the system without changing existing workflows. Passivity Plus is manufactured from Grade 5 Titanium (Ti-6Al-4V-ELI) and is compatible with intraoral scanning, photogrammetry, Grammetry, and conventional stone models, as well as framework materials including zirconia, titanium, PMMA, and hybrid prosthetics.
The company stated that laboratory integration of the components is handled by ROE Dental Laboratory, while clinicians follow their existing seating sequence without additional equipment or techniques.
“Because Passivity Plus integrates with whatever records, materials and workflow a clinician is already using, there is no learning curve and no transition cost,” said Kowalski. “A practice can begin offering a measurably better outcome for full-arch patients from the very next case.”
According to the company, Passivity Plus can be added to all full-arch final cases upon request. The product is also available through the ROE online store for clinicians who fabricate final restorations in-house.
