title: An acellular dermal matrix allograft (Alloderm(®)) for increasing keratinized attached gingiva: A case series.
abstract: BACKGROUND
  Adequate amount of keratinized gingiva is necessary to keep gingiva healthy and free of inflammation. Autografts have been used for years with great success to increase the width of attached gingiva. Autografts, however, have the disadvantage of increasing postoperative morbidity and improper color match with the adjacent tissues. Alloderm(®) allograft has been introduced as an alternative to autografts to overcome these disadvantages.
  
  
  OBJECTIVE
  In this study, the efficacy of alloderm(®) in increasing the width of attached gingiva and the stability of gained attached gingiva was evaluated clinically.
  
  
  METHODS
  Five patients with sites showing inadequate width of attached gingiva (≤1 mm) were enrolled for the study. The width of keratinized gingiva and other clinical parameters were recorded at baseline and 9th month postoperatively.
  
  
  RESULTS
  In all cases, there is the average increase of about 2.5 mm of attached gingiva and was maintained for 9-month. Percentage shrinkage of the graft is about 75% at the end of 3(rd) month in all cases. Excellent colors match with adjacent tissue has been obtained.
  
  
  CONCLUSIONS
  The study signifies that Alloderm(®) results in an adequate increase in the amount of attached gingiva and therefore can be used successfully in place of autografts.
