a Color photograph taken at month 9. Image shows the implant status in the test tubes at month 9. First arrow from left to right: partial disintegration of the implant in BSS surrounded by a turbid appearance corresponding to released particles of the polymer, approximately one-third of the implant still preserves its original cylindrical shape. From left to right: second, third and fourth arrows point the implants placed in 1000cS, 5000cS and heavy silicone oils. The implants remain at the bottom of the tube and no macroscopic signs of disintegration can be observed. b Color photograph taken at month 12. Image shows the implant status in the test tubes at month 12. First arrow from left to right: complete disintegration of the implant in BSS, scattered particles suspended at the bottom of the tube with no visualization of the implant. From left to right: second, third and fourth arrows point the implants placed in 1000cS, 5000cS and heavy silicone oils. The implants remain at the bottom of the tube and no macroscopic signs of disintegration can be observed
