Atrisorb Frequently asked Questions

Q 1 — How long does ATRISORB FreeFlow take to bioabsorb?
ATRISORB FreeFlow retains structural integrity for about 6 months. The barrier is bioabsorbable and slowly disintegrate over a period of 9 to 12 months, depending on the thickness of the material applied.
Q 2 — Is it necessary to apply ATRISORB FreeFlow at a uniform thickness? Can additional polymer be applied to the polymer that has already « set »?
It is not necessary to apply ATRISORB FreeFlow at a uniform thickness. It is important to cover the entire surgical graft area. The amount (thickness) of polymer applied has no impact on efficacy, but the thicker the application, the longer the retention of material. If more polymer is required, it can be added and «set» with sterile water or saline spray.
Q 3 — What is the protocol for the maximum width of the defect in which you can place ATRISORB FreeFlow?
Regenerative therapy should only be performed in defects where a reasonable likelihood of success exists. When treating defects, Class II furcation defects are often considered good candidates for GTR treatment. However, size, defect morphology, and location of these defects vary considerably, and as a result, the predictability of success in these areas may be quite variable. When treating intrabony sites, defects deeper than 3mm have greater potential for regeneration. Based on these factors, general guidelines for defect selection are as follows: Favorable – Class II furcation defects, intrabony defects deeper than 3mm.
Less Favorable – Class III defects, horizontal defects (0-walled), and shallow intrabony defects.
Q 4 — What is the average number of periodontal defects that can be treated with a single patient use syringe of ATRISORB FreeFlow?
The number of periodontal defects that can be treated with a single patient use syringe is dependent on the size and type of defects involved. The single patient use syringe contains 0.5gm (approximately 0.5mL) of polymer, which is enough material to treat 3 to 5 defects.
Q 5 — Is it okay if the barrier is exposed?
Generally, exposed material will disappear within 6 to 8 weeks following surgery due to absorption or attrition. Instruct your patient to keep the exposed material clean by applying chlorhexidine directly to the site with a cotton tip applicator.
Q 6 — How soon after surgery and barrier application can the patient begin normal oral hygiene practices?
The patient should not brush, floss, or use other interdental cleaning techniques around the surgical site for 8 weeks. It is recommended that patients rinse with an antimicrobial agent, such as chlorhexidine, until mechanical tooth cleaning can begin. Professional removal of supragingival plaque should be performed every week for 4 weeks, then biweekly through 8 weeks.
Q 7 — How should ATRISORB FreeFlow be stored?
ATRISORB FreeFlow can be stored at room temperature.
