A comparison of microscrew and suture fixation for porous high-density polyethylene orbital floor implants.
Twenty oral and maxillofacial surgeons compared the surgical features of microscrew fixation technique with a suture technique for fixation of porous high-density polyethylene orbital floor implants. One investigator then compared material features of these two fixation techniques using recently procured bovine ribs. The microscrew technique was found to be quicker (P > .01) and easier (P > .001), and it provided a higher quality of fixation (P > .001) than the suture technique. The microscrew/implant system had a greater pullout strength (P > .001) and shear strength (P > .001) than the suture/implant system.
