MedPark S1 Dental is a xenograft material derived from bovine cancellous bone for the purpose of securing a space where a new bone tissue is formed by filling defects or bony voids of the oral and maxillofacial region due to a surgical injury or a non-surgical injury.

1. Deliver a double packed product to the operating room while keeping it sterilized.
2. Do not use S1 if the sterile package is damaged or opened.
3. Do not use it if any foreign materials are found inside the vial.
4. Do not use S1 bone graft after the expiration date. The validity period is 5(five) years from the date of manufacture.
5. Read and fully understand 'Directions for Use' before surgery and be sure that surgeon knows exactly how to use S1.
6. The surgical instruments must be sterilized before the operation.
7. S1 is an implantable medical device and it should be used in a clean environment, operating room.

The general principles of sterile handling and patient medication must be followed when using S1.

1. When using it, peel off blister Tyvek film. Holding S1 vial firmly, remove the cap. Dispense the granules of S1 into a sterile container.
2. After exposure the bony defect with mucoperiosteal flap, completely remove the granulation tissue and inflammatory tissue.
3. When opening the sterile package, never store remained product.
4. Put saline solution in the bone graft material that has been placed in the sterilized container.
5. Make sure that Recommended amount of saline solution by weight to use S1 successfully.
1) Please keep the following points in mind!
· Please comply with the recommended allowance
· Do not divide the product for multiple uses
· Do not mix with other bone graft
· Mix with saline solutions well enough
2) The amount of saline is most important!
· Place S1 in the tray and hydrate the materials with saline
· Please use the recommended amount of saline only.
· Do not soak in saline after shaping for a surgery.
3) It is important to knead S1 evenly!
· Knead the dough enough for at least 30 seconds by using hands or tools to form a lumpy shape before using S1.
6. After making the product in a paste form suitable for the defect area, apply it to the surgical site using a dental instrument and press it down.
7. After filling the graft, cover the surgical site with mucoperiosteal flap and should be fixed by sutures. Be sure to completely seal the implantation site to prevent exposure.

※ Fundamentally, the use of powder type is recommended for small defects (up to 2 dental alveoli). The chip type is recommended for large defects (> 2 dental alveoli, sinus lifts), however, preferences can vary from dentist to dentist. Powder and Chip type can be mixed together at the dentist's discretion.

This product is supplied in a sterile container. Store as it is at room temperature(1℃ to 30℃) in the shade before use.

3) For bone regeneration, the product is only implantable to bone tissue that is directly connected to living bone tissue and host bone. Experience has shown that movement due to increased physical loads (compression loads) or implantation of implants (2-step procedures) should be avoided until several weeks after insertion of the product. Experiments have shown that the physical loading (compression load) of this product augmented areas is possible after 6 months at the earliest. Implant placement time is determined by the amount of remaining local bone.

5. Pregnant and lactating women, infants, children
