title: [A clinical evaluation of the implant denture in the anterior maxilla over 5 years].
abstract: OBJECTIVE
  To evaluate the clinical results of implant denture in the anterior maxilla over 5 years.
  
  
  METHODS
  From January 2002 to December 2006, two hundred and thirty-four patients with 354 dental implants were followed up for 7-62 months. The results were evaluated by X-ray, clinical examination and patient satisfaction investigation. The 5 year cumulative survival rate (life- table analysis), bone resorption around implants (ANOVA), outcome of soft tissues and esthetics were analyzed using SPSS13.0 software package.
  
  
  RESULTS
  The cumulative survival rate was 97.9%; there was no significant difference among different ways of operation (P=1.00); no significant difference in mean crestal bone loss was found among different years (P=0.88); 19.8% gingival papilla achieved Jemt grade 3; 91.7% patients were satisfied with the restoration.
  
  
  CONCLUSIONS
  Implantation is an effective method for patients losing upper anterior teeth. The cumulative survival rate is as high as 97.9%.
