“…PLLA is already widely utilized in facial bone surgery, with reliable clinical outcomes owing to its sufficient strength to overcome the need for additional support for the fixation of fractures [5,28]. In addition, HA-PLLA shows biodegradability and superior biocompatibility over Ti or Mg alloys [29,30]. Therefore, it could be a highly recommended material in facial bone trauma and craniofacial surgery.…”

Recently, a hydroxyapatite particle/poly-L-lactide (HA-PLLA) composite device was introduced as an alternative to previous fixation systems. In this study, we used finite element analysis to simulate peak von Mises stress (PVMS) and deformation of bone plates and screws with the following four materials—Ti, Mg alloy, PLLA, and HA-PLLA—at a unilateral mandibular fracture. A three-dimensional virtual mandibular model was constructed, and the fracture surface was designed to run from the left mandibular angle. Masticatory loading was applied on the right first molars. Stress was concentrated at the upper part and the neck of the screw. The largest PVMS was observed for Ti; that was followed by Mg alloy, HA-PLLA, and PLLA. The largest deformation was observed for PLLA; next was HA-PLLA, then Mg alloy, and finally Ti. We could rank relative superiority in terms of mechanical properties. The HA-PLLA screw and mini-plate deformed less than 0.15 mm until 300 N. Thus, we can expect good bone healing with usual masticatory loading six weeks postoperatively. HA-PLLA is more frequently indicated clinically than PLLA owing to less deformation. If the quality of HA-PLLA fixation is improved, it could be widely utilized in facial bone trauma or craniofacial surgery.

“…Eighteen studies met the inclusion criteria and were included in the final review. 6,14,15,17–31 There were no additional unique studies identified from Web of Science or Cochrane Collaboration Library. The included studies (n = 18) yielded a total of 455 patients with 613 traumatic mandibular fractures treated with resorbable plates.…”

“…Seventeen studies reported their outcomes according to the resorbable material used and were included in a subset analysis. 6,14,15,17–23,25–31 BiosorbFX (Bionx Ltd, Tampere, Finland) (n = 236/613 fractures; 38.5%) and INION [(Inion, Tampere, Finland) or INION (Striker, Germany)] (n = 131/613 fractures; 21.4%) were the most commonly used resorbable materials. Lactosorb (Walter Lorenz, Jacksonville, Fla.) and INION [(Inion, Tampere, Finland) or INION (Striker, Germany)] had overall complication rates of 32.5% (n = 13/40 fractures) and 28.2% (n = 37/131 fractures), respectively, representing the resorbable implants with the highest rates of adverse events.…”

Background:Mandibular fractures in adults commonly require rigid fixation to ensure proper occlusion while minimizing infection risks. Numerous centers have assessed the efficacy of resorbable materials as a potential alternative to metallic plates. The purpose of the current systematic review and meta-analysis is to shed light on overall outcomes for resorbable implants and to compare these results to those for metallic counterparts.Methods:A systematic review of clinical studies reporting outcomes for resorbable plates for mandible fractures was carried out. The reported outcomes were hardware failure/exposure, infection, wound dehiscence, reoperation, malocclusion, and nonunion. The results were pooled descriptively and stratified according to fracture and implant type. A subset meta-analysis of prospective studies comparing metallic and resorbable implants was also carried out.Results:Eighteen studies were included for a total of 455 patients managed with resorbable implants (mean follow-up, 8.95 months) with an overall complication rate of 19.8 % (n = 90/455). Infection (n = 31/455, 6.8%) and wound dehiscence (n = 28/455, 6.2%) were the most common complications. Nonunion occurred in 1.1% (n = 5/455) of patients. Seven studies were included in a meta-analysis, and the rates of adverse events in the resorbable and metallic groups were 18.0% (n = 32/178) and 18.3% (n = 33/180), respectively, with no statistically significant difference between both cohorts (95% CI 0.58, 1.82, P = 0.93).Conclusions:This study suggests that there are no statistical differences in outcomes for patients with mandible fractures managed with resorbable or metallic implants. In the absence of meta-analyses or large randomized controlled trials, the current study provides surgeons with an evidence-based reference to guide decision-making.

The aim of this review was to present and discuss current views on the treatment of condylar fractures (CFs). The authors addressed the following issues: the etiology, epidemiology and mechanisms of CFs; strategies and methods for the treatment of CFs. Moreover, the choice of surgical approach for the open treatment of CFs as well as techniques and materials used for fixation of CF are discussed.The PubMed database was used to search for relevant articles published between 2000 and 2018. The analysis referred to both original and review papers (including meta-analyses) that concerned adult patients. There are still differences in opinions among researchers regarding the choice of appropriate treatment – closed or open. There is no consensus among open treatment supporters in choosing the right surgical approach. The important question is which material to choose for osteosynthesis of the condylar fracture.Recent studies show satisfactory results in terms of stability of condylar osteosynthesis with the use of 3D plates. Further discussion is required on the choice of material for fixation of the condylar fracture and, in particular, on the possibility of using resorbable materials.
