title: [The application of guided bone regeneration technique in the restoration of maxillary lateral incisor with bone defect].
abstract: OBJECTIVE
  To evaluate the clinical effectiveness and the satisfaction on aesthetic effectiveness of application of guided bone regeneration (GBR) technique in maxillary lateral incisor implant site.
  
  
  METHODS
  Ninety patients were selected who only lost maxillary lateral incisor and placed with 101 implants(the implant systems were 3i, Osstem, ITI, Ankylos, BLB). The final restorations were porcelain-fused-to-metal crowns.  Clinical and X-ray examinations were conducted and esthetic results were observed at 3, 6,12 months after dental implant prosthetics.
  
  
  RESULTS
  The follow-up time was 12 months, all patients achieved successful implantation and good osseointegration around the implant. The esthetic results were perfect .Among the 90 cases, 90.7%, 92.8% and 95.5% of  the patients were satisfied with the final outcomes 3,6,12 months after prosthetics.
  
  
  CONCLUSIONS
  Good clinical effectiveness and satisfaction on aesthetic effectiveness can be obtained with GBR technique applied in maxillary lateral incisor implant site. Appropriate use of GBR technique is the solution of bone defect of maxillary lateral incisor implant site.
