Osstem Angled Abutment

Angulated abutments can be used in a single tooth and partially or totally edentulous situations. They are used in the fabrication of cement-retained restorations, single crowns, or bridges, can be used in unparalleled implant placement cases for angle compensation.
Osstem^® TS Compatible Angled Anatomic Abutment is fixated by hand tightening with a 1.2mm hex driver.

The Osstem angled abutment is a pre-angled prosthetic abutment used to correct implant angulation for cement-retained single-unit and short-span restorations. Where a straight abutment would place the crown along an unfavorable path - a common situation in the anterior maxilla, where implants are often angled facially to follow the bone - an angled abutment redirects the restorative axis so the crown can be delivered esthetically and functionally. Among angulated abutments, the pre-angled design gives clinicians a stock, chairside-ready solution for the majority of routine angle-correction cases.

Yagu's Osstem angled abutment is offered in 15° and 25° corrections, machined from Ti-6Al-4V ELI Grade 5 titanium on CITIZEN Swiss CNC centers, with the Osstem connection held to a ±5 μm tolerance. The preparable titanium body allows the margin and axial walls to be refined chairside or in the laboratory, and a range of gingival heights positions the finish line relative to the tissue. As a dental angled abutment for cement-retained restoration, it re-orients the crown while maintaining a stable connection to the implant; as a dental implant angled abutment, it addresses the angulation problems that make many esthetic-zone cases challenging with stock straight components. The result is an economical, connection-accurate route to a well-aligned crown without a custom milling step.

• Connection: Osstem^® TS Hexagon
• Degree: 17°/30°
• Abutment Diameter: Ø4.0mm / Ø5.0mm / Ø6.0mm
• Cement / combination retained prosthesis
• Single / bridge restoration that requires path modification
• Fixture level impression
• Gold coloring for margin's esthe
• Material : grade 5 (Ti-6Al-4VV)
• Connect using 1.2 hex torque driver
• Recommended tightening torque: mini 20Ncm / regular 30Ncm
• Qualities: High Corrosion Resistance, General Bio-compatibility
• 15° and 25° angle correction. Two pre-angled options re-orient the crown axis to correct facially or otherwise angled implants for a favorable restorative path.
• Preparable titanium body. The margin and axial walls can be adjusted chairside or in the lab to set finish-line position, taper, and retention for the cement-retained crown.
• ±5 μm Osstem connection. The CNC-finished interface seats passively and maintains a stable screw joint under occlusal load.
• Ti-6Al-4V ELI Grade 5 titanium, ASTM F136. Medical-grade titanium provides the fatigue strength and biocompatibility required at the angled interface, where stress concentrates.
• Range of gingival heights. Multiple collar heights keep the cement margin accessible for excess-cement removal across varied soft-tissue thickness.
• Defined rotational positioning. The engaging index locks the angle direction so the correction is oriented as planned.
• Optional TiN (gold-tone) coating. A thin ceramic coating supports soft-tissue esthetics through thin anterior mucosa.
• 100% dimensional inspection. Angulation, height, and connection geometry are verified per lot under the ISO 13485 quality system.

The angled abutment is machined for the Osstem internal connection, including Osstem TS III, TS IV, SS, GS, and MS systems and the compatible Hiossen ET III platform. Angulation and gingival height are matched to these systems so the abutment seats at the correct emergence level and the engaging index orients the correction as planned. References are selected by platform diameter and by the required 15° or 25° correction.

Compatibility with the Osstem connection is confirmed by 100% interface testing against reference geometry before release. Osstem and Hiossen are trademarks of their respective owners; Yagu Dental manufactures compatible components and is not affiliated with or endorsed by these companies.

The angled abutment is used chiefly in cement-retained single-unit restoration where implant angulation must be corrected for esthetics or function. In the anterior maxilla, implants are frequently placed with facial inclination to remain within the labial bone; a 15° or 25° abutment redirects the crown palatally so the incisal edge and emergence follow the natural tooth position rather than the implant axis. In posterior cases, angle correction can align a crown that would otherwise be delivered along an unfavorable path relative to the opposing dentition.

The preparable body allows the margin to be positioned just at or slightly below the gingival crest, keeping the cement line accessible - an important detail given the association between retained subgingival cement and peri-implant inflammation. The engaging connection fixes the direction of the angle correction, and the ±5 μm interface supports passive seating that limits micromovement and screw loosening at the angled junction, the region of highest stress. For cases needing a screw-retained solution or full-arch angle correction, angled screw-channel abutments or angled multi-unit abutments are selected instead; the pre-angled abutment described here efficiently resolves the common single-unit, cement-retained angulation problem.

As with any cement-retained abutment placed near the tissue, complete seating is confirmed radiographically before cementation, and the gingival height is selected so excess cement can be reached and removed. The abutment screw is torqued to the system-recommended value and, where an access channel is present, sealed before the crown is cemented.

An angled abutment concentrates bending stress at the angle correction and the screw seat, so fatigue performance is the central material requirement. Ti-6Al-4V ELI Grade 5 titanium provides high fatigue strength, and the ELI grade's reduced interstitial content improves fracture toughness precisely where the geometry changes direction. Titanium's stable oxide layer and corrosion resistance support long-term biocompatibility at the transmucosal collar, and the optional TiN coating warms the gingival shade for thin anterior tissue without meaningful added thickness.

Machining on Japan-imported CITIZEN Swiss CNC centers cuts the angled body and the concentric Osstem index in a controlled operation that holds the connection to ±5 μm, so the correction direction and seating are repeatable across a lot. The margin and axial geometry are machined to consistent dimensions to support predictable preparation and crown fit. Conformity is documented to ASTM F136 and ISO 5832-3, and each lot undergoes 100% dimensional inspection of angulation, height, and connection geometry under the ISO 13485 quality system before shipment, with material certificates and lot traceability available.

In the esthetic zone the angled abutment must survive both cyclic load and the visual demands of thin anterior tissue, so Yagu machines the angle transition with controlled radii to limit stress concentration and, where specified, applies a thin TiN layer that warms the gingival shade without altering the fit of the overlying crown. The implant index is cut concentric with the corrected axis so the direction of correction is reproducible from unit to unit, letting a laboratory plan emergence with confidence. Alloy chemistry is confirmed by mill certificate and each lot is gauged for angle value, gingival height, and connection geometry, because an abutment that corrects to a slightly different angle than specified would shift the crown position in the most visually unforgiving part of the mouth.
