EthOss Synthetic Bone Graft

EthOss® artificial bone — a synthetic solution that simplifies the management of bone defects

EthOss® is a synthetic bone graft used for filling, augmentation, and reconstruction of bone defects in the maxillofacial region. The material is commonly applied in intrabony defects, alveolar ridge augmentation, and socket preservation after tooth extraction.

The key differentiating feature of EthOss lies in the combination of β-tricalcium phosphate and calcium sulfate. This combination creates a stable, controllable consistency and allows the material to function as a graft with built-in stabilization during placement.

Modern synthetic material EthOss® is ideally suited for:

• Implantologists and surgeons working with routine defects who value a clean, predictable protocol in which the material maintains its shape and volume during placement. EthOss is positioned as a graft that is completely replaced by the patient’s own bone.
• Periodontists managing intrabony defects who expect a stable osteoplastic material with a clear and predictable healing timeline.
• Clinics whose patients deliberately choose solutions without animal or human origin, as EthOss is a fully synthetic material.

Typical clinical indications

• Socket preservation after tooth extraction
• Local alveolar ridge augmentation
• Intrabony defects in periodontal and surgical procedures

Material properties observed in daily clinical practice

Innovative formula and composite structure

The material consists of 65% β-tricalcium phosphate and 35% calcium sulfate.
β-tricalcium phosphate forms an osteoconductive scaffold for bone formation, while calcium sulfate provides cohesion and stability during placement.

In practice, this results in reduced granule dispersion and easier defect shaping.

Osteogenesis

EthOss is typically fully resorbed within 6–12 months.
This approach is often preferred by clinicians who avoid materials that remain in tissues long-term and expect gradual replacement of the graft with native bone.

Key considerations during material preparation

Only sterile 0.9% NaCl saline solution is used for mixing.
This reduces variability within the protocol and allows for a stable, predictable consistency.

Planning the second surgical stage

The recommended re-entry time is approximately 12 weeks.
This timing is convenient for follow-up or second-stage procedures; however, the final decision should always be based on clinical findings and CT or radiographic assessment.

Selecting the appropriate volume for each clinical case

EthOss is available in 3×0.25 cc, 3×0.5 cc, and 3×1 cc formats.
This allows precise volume selection for single sockets or localized defects without material waste.

Practical advantages of EthOss®

• Clear and predictable timeline: re-entry is typically planned at around 12 weeks, with complete resorption within 6–12 months according to manufacturer data.
• Predictable handling: mixing with saline creates a stable mass that saves time and simplifies manipulation in daily practice.
• Fully synthetic composition with no animal or human origin, which is a decisive factor for certain patients and clinics.

Clinical limitations and trade-offs

• In selected cases, EthOss® enables a simplified approach; however, in large or complex defects, decisions regarding membranes, fixation, and soft-tissue management must be based on the specific clinical situation.
• For clinicians accustomed to xenografts with long-term volumetric stability, EthOss represents a different treatment philosophy. According to the manufacturer, the material fully resorbs within 6–12 months, and expectations regarding bone remodeling should be adjusted accordingly.

How EthOss meets the needs of different specialties

Implantologist and surgeon
Fast protocols, material stability, and predictable timelines are essential. EthOss offers re-entry at approximately 12 weeks and complete resorption within 6–12 months based on declared data.

Periodontist
Key factors include suitability for intrabony defects and a clear healing timeline. EthOss indications include infrabony defects, meeting these clinical requirements.

Maxillofacial surgeon and complex reconstructions
Such cases typically require materials with predictable quality, defined parameters, and evidence-based performance. EthOss has a synthetic composition with declared resorption and timing parameters; however, in large defects, protocols involving membranes, blocks, or fixation are often preferred. EthOss does not replace surgical logic but integrates into it.
