Re-entry after 3 months for reassessment and implant placement
bone loss
CREST, BONE LOSS
After the administration of lidocaine HCl 2% and epinephrine 1:100,000, ST was reassessed from the mid-buccal region of the extraction site at the level of alveolar crest (2.5 mm below the imaginary line connecting zenith points of the adjacent teeth) using a periodontal probe (UNC-15). Then, a mid-crestal incision and flap elevation was performed. The amount of vertical bone loss was calculated after measuring the distance between the alveolar crest and the CEJ. The amount of horizontal bone loss was calculated after measuring the ridge width in the third month. Then, implant placement was done.
