title: [Internal fixation for zygomatic arch fracture with super-high molecular weight poly D, L-lactic acid mini-plates and screws: a study in dogs].
abstract: OBJECTIVE
  To investigate the internal fixation effects of super high molecular weight (Mv = 6.0 x 10(5) kD) poly D, L-lactic acid(PDLLA) mini-plates and screws.
  
  
  METHODS
  10 dogs were utilized in this experiment with the self-contrast study method, comparing with the titanium mini-plates and screws.
  
  
  RESULTS
  The mechanical properties of the PDLLA mini-plates and screws appeared to be sufficient to enable undisturbed healing of depressed zygomatic arch fracture.
  
  
  CONCLUSIONS
  The good fixation effect of PDLLA mini-plates and screws was as same as that of the titanium mini-plates and screws without the need of secondary operation.
