About this trial
The main purpose of the study is to measure and localize immediate post extraction changes i.e. socket expansion versus no width change along the socket wall and identify whether the immediate post-extraction ridge width condition (expansion or no change) is a determinant of buccolingual ridge width and height changes 4 months following extraction and ridge preservation.

Trial outcomes
Primary outcomes
1
Buccolingual ridge width
Buccolingual ridge width will be measured through a stent via ridge mapping calipers. The measurement locations will be at 1mm, 3mm and 5mm from the midbuccal crest. The same measurements will be recorded at all selected time points.
Time frame
(1) After local anesthesia and before extraction, (2) immediately after extraction and (3) 4 months after extraction and alveolar ridge preservation2
Ridge height
Ridge height will be measured through a stent via a periodontal probe as the distance between bone and predetermined landmarks on the stent. The measurement locations will be mesial buccal, midbuccal, distal buccal, mesial lingual, midlingual and distal lingual. The same measurements will be recorded at all selected time points.
