GUIDOR matrix barrier is composed of resorbable polymers that have a history of more than 20 years of use in the food and medical industry (2).

Presented in a unique multi-layered design which stabilizes the wound site, aids in early integration of gingival connective tissues and effectively impedes epithelial downgrowth, which together contribute to “true cell occlusion" (2).

 

Laser perforations on the upper (A) and lower layer (B) allow fluid exchange with larger geometry on the upper layer to encourage selective tissue integration and contribute to an “outstanding clinical success” (3).

Tissue integration, stabilisation and resorption (6)

1

After 6 Weeks

The design of GUIDOR matrix barrieris easily recognized, including the matrix sealing bar (2), matrix ligature (3), external layer (5), internal layer (6) and inner space (4). The connective tissue (1)surrounds the matrix and penetrates the inner space (4) of the matrix. Newly formed periodontal ligament (8) and alveolar bone (7) are seen in close contact with the material (6).

2

After 3 Months

Resorption has started. The degrading matrix (9) is surrounded by dense connective tissues. Newly formed bone(10) is seen next to the matrix (9) as well as large amounts of cementum (11)with inserting collagen fibers.

3

After 6 Months

No GUIDORmatrix barrier material is visibly detected. The new attachment comprised of periodontal ligaments (12)and cementum (11) has formed between the new alveolar bone (10) and root surface.

After 24 Months

No traces of GUIDOR matrix barrierremain, indicating the complete resorption of the matrix and restoration of the tissues.
