title: [Application of valplast dentures in the temporary restoration of single missing anterior tooth].
abstract: OBJECTIVE
  To evaluate the value of valplast dentures in the temporary restoration of single missing anterior tooth.
  
  
  METHODS
  Totally 76 patients who needed temporary restoration of single missing anterior tooth were involved and equally divided into two groups according to their own choices of procedures: group A, with valplast dentures as their temporary dentures and group B, with conventional removable partial dentures as their temporary dentures. Meanwhile,38 patients who had their single anterior teeth pulled out and did not need temporary dentures were enrolled as control group without any temporary restoration, and impressions were taken immediately before the temporary dentures were used (2 weeks after tooth extraction) and before the initiation of permanent restorations (97-100 days after tooth extraction).The heights of clinical crowns of the adjacent teeth were also recorded twice from plaster models made from the impressions.The height of labial gingiva recession was calculated as the difference between the two heights recorded.
  
  
  RESULTS
  The height differences of clinical crowns of the adjacent teeth was 0.5mm (range: 0.0-1.2mm) in group A, which was significantly larger than those in group B [0.0mm;(range: 0.0-0.6mm)](P<0.05) and in group C[0.0mm;(range: 0.0-0.4mm)](P<0.05).However, the difference was not significant between group B and group C (P>0.05).
  
  
  CONCLUSIONS
  Application of valplast denture as temporary denture may cause labial gingival recession of the adjacent teeth, and therefore is not suitable for the restoration of single missing anterior tooth.
