Intended Use

PerioGlas® is intended to fill and/or augment dental intraosseous and oral/maxillofacial defects including: - Periodontal defects ● - Ridge augmentation . - Extraction Sites ● - Cranio-facial Augmentation . - Sinus Lifts . - Cystic Defects .

Device Story

PerioGlas® is a synthetic, osteoconductive bone void filler composed of Bioglass® (CaO, Na2O, SiO2, P2O5) in 90-710 um particulate form. Supplied sterile in a cup; mixed with saline or patient blood to create a sandy paste. Applied by clinicians to dental/oral/maxillofacial defects to facilitate bone repair. Acts as a scaffold for bone growth; can be used alone or as an extender for autogenous/allograft bone. Benefits include safe, biocompatible bone augmentation in various clinical scenarios (e.g., ridge, sinus, cystic defects).

Clinical Evidence

Clinical evidence includes prospective, retrospective, and case studies across various dental/oral/maxillofacial defects. Periodontal studies showed no significant differences between PerioGlas®/bone mixtures and PerioGlas® alone regarding Clinical Attachment Level (CAL), Pocket Depth Reduction (PDR), and osseous fill. A four-clinician retrospective study reported a 91% implant success rate for ridge augmentation, extraction sites, and sinus augmentation. Animal models (rabbit calvarial, canine split-rib) demonstrated superior bone formation when using PerioGlas® as a graft extender compared to either material alone.

Technological Characteristics

Synthetic osteoconductive particulate; composition: 24.5 wt% CaO, 24.5 wt% Na2O, 45 wt% SiO2, 6 wt% P2O5; particle size 90-710 um. Supplied sterile in Tyvek-sealed PET-G cup. Mechanical filler; no energy source or software.

Indications for Use

Indicated for patients requiring bone graft material for oral/maxillofacial and dental intraosseous defects, including periodontal/infrabony defects, ridge augmentation, extraction sites, cranio-facial augmentation, cystic cavities, and sinus lifts. Used alone or as a graft extender with autogenous bone or allograft bone particulate.

Regulatory Classification

Identification

Bone grafting material is a material such as hydroxyapatite, tricalcium phosphate, polylactic and polyglycolic acids, or collagen, that is intended to fill, augment, or reconstruct periodontal or bony defects of the oral and maxillofacial region.

Special Controls

*Classification.* (1) Class II (special controls) for bone grafting materials that do not contain a drug that is a therapeutic biologic. The special control is FDA's “Class II Special Controls Guidance Document: Dental Bone Grafting Material Devices.” (See § 872.1(e) for the availability of this guidance document.)(2) Class III (premarket approval) for bone grafting materials that contain a drug that is a therapeutic biologic. Bone grafting materials that contain a drug that is a therapeutic biologic, such as biological response modifiers, require premarket approval. (c) *Date premarket approval application (PMA) or notice of product development protocol (PDP) is required.* Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

Predicate Devices

• Calcitite (K852682)
• Bio-Oss (K970321)

### Device Description

PerioGlas® is a synthetic osteoconductive particulate bone/void filler that is intended for oral/maxillofacial and dental intraosseous defects use. The material composed of Bioglass® (24.5 wt % CaO, 24.5 wt % Na20, 45 wt % SiO2, 6 wt % P2O5) with a particle size range of 90-710 um. It is supplied sterile in a Tyvek sealed PET-G cup that is protected by a shrink wrapped cardboard box. It is mixed with sterile water (saline) or the patient's own blood to form a wet sandy paste which is applied to the defect.

#### Predicate Device

PerioGlas® is substantially equivalent to legally marketed osteoconductive bone filling and/or augmentation devices in the U.S. including Calcitite (K852682) and Bio-Oss (K970321). Any minor differences between PerioGlas® and the predicate devices do not raise new questions of safety or effectiveness.

## Intended Use

PerioGlas® is intended to fill and/or augment dental intraosseous and oral/maxillofacial defects including:

- Periodontal defects ●
- Ridge augmentation .
- Extraction Sites ●
- Cranio-facial Augmentation .
- Sinus Lifts .
- Cystic Defects .

#### Device Testing

The performance of PerioGlas® was evaluated in animal models versus hydroxylapatite predicate devices. The rate of bone formation, amount of bone formed and the biomechanical

{1}------------------------------------------------

properties including peak compressive loads and compressive stiffness were substantially equivalent to each other and normal bone.

PerioGlas® Bioglass® particulate was also evaluated as a graft extender with finely ground autogenous bone in a rabbit calvarial defect model and a canine split-rib model. In both of these models, bone formation or graft site augmentation was greater for the mixture of bone and Bioglass® than for either alone.

Clinical Data including prospective, retrospective and case studies were reviewed and evaluated for various dental and oral/maxillofacial intraosseous defects including a variety of ridge, periodontal, extraction sites, sinus augmentation and cystic defects using PerioGlas® alone and/or as a graft extender.

Periodontal studies showed no significant differences between PerioGlas®/Bone graft mixtures and PerioGlas® alone for a variety of clinical parameters including Clinical Attachment Level (CAL), Pocket Depth Reduction (PDR) and osseous fill. Results did suggest that there may be a synergistic effect when the two graft materials are combined.

Ridge augmentation, extraction site, sinus augmentation, cystic defect and general osseous reconstruction studies demonstrated safe and efficacious use of PerioGlas® alone and/or as a graft extender in these indications. Results from a four clinician retrospective study, as measured by the overall implant success rate (91%), indicate that the use of PerioGlas® as a bone graft extender is safe and efficacious for ridge augmentation, extraction sites and sinus augmentation.

Documented case reports representing all of the summarized categories with clinical evaluations and radiographs support the safety and efficacy of PerioGlas® alone or as a bone graft extender in bone/void filling.

#### Conclusions

The animal and/or clinical performance, safety and effectiveness data show that the device performs as well as or better than predicate hydroxylapatite devices as an osteoconductive bone void filler both alone or as a bone graft extender.
