  • Title: Lag-screw fixation of anterior mandibular fractures using biodegradable polylactide screws: a preliminary report.
    Author: Kallela I, Iizuka T, Salo A, Lindqvist C.
    Journal: J Oral Maxillofac Surg; 1999 Feb; 57(2):113-8. PubMed ID: 9973116.
    Abstract:
    PURPOSE: The purpose of this study was to evaluate the utility of biodegradable, self-reinforced poly-L-lactide screws (SR-PLLA) for lag-screw fixation of anterior mandibular fractures. PATIENTS AND METHODS: SR-PLLA lag-screws were used to stabilize anterior mandibular fractures in 11 patients. Maxillomandibular fixation was used to treat concomitant mandibular condyle fractures for 2 weeks in four patients and for 1 and 5 weeks in two patients. Clinical and radiologic follow-up lasted for 6 months in 36% of patients and for 1 year in 64%. RESULTS: Healing of all anterior fractures was uneventful, with no displacement or delay of bony union. No adverse reactions to the biodegradable screws were seen during follow-up. CONCLUSION: Biodegradable SR-PLLA screw fixation seems to be a new and promising way of treating anterior mandibular fractures.
