title: Comparison of vestibular sulcus depth in vestibuloplasty using standard Clark's technique with and without amnion as graft material.
abstract: BACKGROUND
  A number of materials are used as grafts in vestibuloplasty like mucosal and skin grafts with several advantages and disadvantages. To circumvent the disadvantages of these grafts, biological membranes such as amnion membranes are often recommended.
  
  
  METHODS
  The objective of this study was to clinically assess the vestibular sulcus depth in vestibuloplasty using Clark's technique with and without amnion as graft material. Twenty edentulous patients underwent mandibular labial vestibuloplasty using Clark's technique. Amnion was used as graft material in 10 patients (group I) and no grafts used in remaining 10 patients (group II). The vestibular depth was evaluated at time intervals of 1 week, 2 weeks, 1 month and 3 months, postoperatively.
  
  
  RESULTS
  Mean postoperative vestibular depth after 3 months in group I and II were 10.0 ± 3.13 mm and 7.8±0.63 mm, respectively. Mean of 2.2 ± 2.50 mm increase in depth was achieved after 3 months in Group I.
  
  
  CONCLUSIONS
  Amnion graft is a viable and reliable option that promotes early healing and maintains postoperative vestibular depth.
