Primary Outcome Measures

Name	Time	Method
Bucolingual ridge width. Timepoint: In first surgery and 4-6 months after the first surgery. Method of measurement: Coronal border distance from of buccal aspect to the coronal border of the lingual/palatal aspect of the alveolus or ridge at midpoint(with caliper to the nearest tenth of millimeter; 2).;Alveolar ridge height. Timepoint: In first surgery and 4-6 months after the first surgery. Method of measurement: The distance between the most coronal point of buccal side of the socket or ridge and the most apical end of the stent at the place of its notch, and similar measurement at lingual/palatal aspect(Michigan-O- probe with William marking was used).;Bone formation. Timepoint: 4-6 months after the first surgery. Method of measurement: With image analysis software ( percent).;Type of bone. Timepoint: 4 months after the first surgery. Method of measurement: Optic microscopy.;Residual material. Timepoint: 4 months after the first surgery. Method of measurement: Optic microscopy.
