“…6,7 Although titanium is the standard for bone plates and screws for human use, it has been reported that the material can be found in local and regional lymph nodes years after placement. 8,9 The pathologic consequence, if any, is unknown and the titanium debris has never been definitively linked to a disease. Once the titanium serves the purpose of maintaining the position of bone segments during healing, it is no longer necessary.…”

Purpose-This report compares the skeletal stability and treatment outcomes of 2 similar cohorts undergoing bilateral sagittal osteotomies of the mandible for advancement. The study groups included patients stabilized with 2-mm self-reinforced polylactate (PLLDL 70/30), biodegradable screws (group B), and 2-mm titanium screws placed in a positional fashion (group T).Materials and Methods-Sixty-nine patients underwent bilateral sagittal osteotomies of the mandibular ramus for advancement utilizing an identical technique. There were 34 patients in group B and 35 patients in group T. Each patient had preoperative, immediate postoperative, splint out, and 1-year postoperative cephalometric radiographs available for analysis. The method of analysis and treatment outcomes parameters are identical to those previously used. Repeated measures analysis of variance was performed with means of fixation as the between-subject factor and time as the within subject factor. The level of significance was set at .01.Results-There were no clinical failures in group T and a single failure in group B. The average difference in stability between the groups is small and subtly different at the mandibular angle. The data documented similarity of the postsurgical changes in the 2 groups with the only statistically significant difference being the vertical position of the gonion (P < .001) and the mandibular plane angle (P < .01) with greater upward remodeling at gonion in group T.Conclusions-Two-mm self-reinforced PLLDL (70/30) screws can be used as effectively as 2-mm titanium screws to stabilize the mandible after bilateral sagittal osteotomies for mandibular advancement. The difference in 1-year stability and outcome is minimal.Biodegradable internal fixation has become increasingly popular in many orthopedic applications and has gained wide acceptance in pediatric craniofacial surgery, where heavy

“…in many studies about orthopedics and dermatology; ti particles have been found in the peri-implant area (18) and in lymph nodes among cases that lack a ti-based implant (13,25,32) and some of these studies reported an increased level of titanium in the serum (16). Meningaud et al (22) studied the metal release from titanium miniplates in maxillofacial surgery and found no correlation between ti levels and duration of plating. they suggested that released ti may precipitate locally as in physiological conditions; ti ions cannot be chelated for transportation.…”

“…The excellent properties of corrosion resistance, biocompatibility and osseointegration led to the acceptance of titanium as the metal of choice in all internal devices in contemporary maxillofacial surgery. One of the biggest arguments against titanium has been the presence of metal ions in the vicinity of the site leading to speculation that metal is gradually leached out by the action of body fluids on the metal [3,4]. There have also been reports of titanium deposits being seen in the adjacent lymph nodes [5][6][7].…”
