Overview

ROE Dental Laboratory has introduced ArchBridge for Overdenture, a patent-pending digital scanning system and laboratory workflow for fixed and removable overdenture cases. The company says six reusable titanium scan bodies capture attachment positions intraorally, enabling the laboratory to position and cure overdenture housings before delivery rather than relying on chairside acrylic pickup.

Background

Overdenture workflows require accurate transfer of attachment positions from the patient to the laboratory. ROE reports that digital records have not always allowed the laboratory to determine attachment positions confidently, prompting development of the ArchBridge scan body system. The company describes the system as an extension of its Grammetry full-arch scan body technology, adapted to overdenture abutment attachments. Related literature in the supplied context discusses digital denture production, but does not provide clinical outcome data for ArchBridge.

Data Highlights

Feature	Details reported by ROE
Scan bodies	Six reusable titanium scan bodies with distinct geometries; press-fit onto overdenture abutments.
Scanning features	Tactile seating is intended to help confirm placement; sandblasted surfaces are intended to reduce optical reflections.
Laboratory workflow	ROE positions and cures housings before delivery; the company says this removes the need for poured models and analogs for attachment positioning and replaces chairside blockout and intraoral acrylic pickup.
Applications and compatibility	Reported compatibility with most major overdenture systems; applications include replacement of an existing overdenture, conversion of a healing denture, and conversion of a removable overdenture to a fixed hybrid restoration.
Kit and reuse	The kit includes spacers and placement tools; scan bodies can be autoclaved between patients.

Key Findings

ArchBridge is a patent-pending digital scanning system and workflow for fixed and removable overdenture cases, according to ROE.
Six reusable titanium scan bodies press-fit onto overdenture abutments, with distinct geometries intended to provide individual reference points during intraoral scanning.
ROE says tactile seating helps clinicians confirm scan body placement and the sandblasted surface is intended to reduce reflections during optical capture.
The laboratory positions and cures overdenture housings before delivery, replacing conventional chairside blockout and intraoral acrylic pickup procedures, according to the company.
ROE states that the workflow eliminates poured models and analogs during attachment positioning and is intended to address housing binding or spacer movement during curing.
Reported applications include replacing an existing overdenture, converting a healing denture, and converting a removable overdenture to a fixed hybrid restoration; the system is described as compatible with most major overdenture systems.

Clinical Implications

The system is presented as a workflow option for clinicians treating the overdenture applications specified by ROE, with attachment-position records captured intraorally and housing placement completed by the laboratory. The supplied source describes the design and intended workflow but does not report comparative clinical outcomes or independent performance data for ArchBridge.

Conclusion

ArchBridge combines reusable, geometry-specific scan bodies with laboratory-side housing placement and curing. Its stated workflow and applications are based on information provided by ROE Dental Laboratory.
