• Device Name: ENDOBON XENOGRAFT GRANULES
• Applicant: Biomet 3i
• Product Code: LYC · Dental
• Decision Date: May 13, 2011
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 872.3930
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Endobon® Xenograft Granules are used in the following dental and/or surgical procedures: . Alveolar ridge augmentation/reconstruction. . . Filling of defects after root resection, apicoectomy, and cystectomy. . . Filling alveoli after tooth extraction. . . Sinus elevation. This product should not be used in non-peridontal mandibular applications.

Device Story

Endobon Xenograft Granules are bovine-derived hydroxyapatite ceramic granules used as an implantable, non-resorbable osteoconductive scaffold in dental and surgical procedures. The material is processed via high-temperature pyrolysis (>900°C) and sintering (>1200°C) to ensure complete deproteinization and elimination of biological contaminants (bacteria, viruses, prions). The device is intended for use by dental professionals to fill bone defects, augment alveolar ridges, or perform sinus elevations. It provides a structural scaffold to support bone healing. The product is not for use in non-periodontal mandibular applications.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on chemical composition analysis (EDS) comparing Endobon to the predicate device and literature review.

Technological Characteristics

Material: Bovine-derived hydroxyapatite ceramic [Ca5(PO4)3OH]. Manufacturing: Two-step high-temperature process (pyrolysis >900°C, sintering >1200°C). Function: Non-resorbable osteoconductive scaffold. Form: Granules.

Indications for Use

Indicated for dental and surgical procedures including alveolar ridge augmentation/reconstruction, sinus elevation, filling of bone defects (root resection, apicoectomy, cystectomy), and filling alveoli post-tooth extraction. Contraindicated for non-periodontal mandibular applications.

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

• BioOss (Xenograft Bone Granules (Bovine)) (K980679)

Reference Devices

device pursuant to 21 C.F.R. § 872.3930 regulations. Legally Marketed Name of Manufacturer: GEISTLICH PHARMA AG CH -Predicate Devices: 6110 Wolhusen Switzerland Washington, DC 20036 Device Name: Xenograft Bone Granules (Bovine) Device Trade Name: BioOss Endobon Xenograft Granules is a modification to Endobon Purpose of the Traditional 510(k) Xenograft Granules, K980679. The purpose of this 510K is to notice: add Sinus Elevation to the current Indication for Use. Device Description: Endobon Xenograft Granules consist of bovine derived hydroxyapatite ceramic granules. Endobon Xenograft Granules are used in the following dental Intended Use: and/or surgical procedures: . Alveolar ridge augmentation/reconstruction, . Sinus elevation, . Filling of resection defects in benign bone tumor, bone cysts, or other defects in the alveolar ridge or wall, . Filling of bone defects after apicectomy, ● Filling alveoli after tooth extraction. This product should not be used in non-peridontal mandibular applications. Endobon - hydroxyapatite xenograft granules are derived from Technological Characteristics: cancellous bovine bone that are used as an implantable material to function as a non-resorbable osteoconductive scaffold for dental applications. A two-step, high-temperature manufacturing process (pyrolysis at a temperature above 900 ℃ and sintering at a temperature above 1200ºC) allows complete deproteinization as well as destruction of potential residual bacteria, virus and prions. The slow resorption rate attributed to Endobon and other similar materials processed in the same manner relates to the crystalline-like structure of 95% of the hydroxyapatite (HA) in Endobon. The resorption rate of hydroxyapatite (HA) increases as crystallinity decreases, and the crystallinity is highly dependent on the sintering temperature. High sintering

increase in crystallinity.

The precise chemical name of the hydroxyapatite is pentacalcium hydroxide (tris) phosphate [Ca5 (PO4)3 OH]. Semiquantitative Energy-Dispersive Spectrometry (EDS) analysis of the chemical composition of both Endobon and Bio-Oss grafting materials from Jensen et al. 1996 are presented in Table 1. The data demonstrates similarities in both weight percentage and atomic percentage of the elements.
