post extraction healing

Question 1

Soft tissue alterations:

Answer 1

1. cell proliferation within the mucosa resulting in an increase of its connective tissue volume.
2. the soft tissue wound becomes epithelialized and a keratinized mucosa will cover the extraction site.
3. The contour of the mucosa subsequently adapts to follow the changes that occur in the external profile of the hard tissue of the alveolar process.
4. the contraction of the ridge is the net result of bone loss as well as loss of connective tissue.

Question 2

Hard tissue alterations:

Answer 2

1. hard tissue walls of the alveolus will resorb
2. the center of the socket becomes filled with cancellous bone
3. the overall volume of the site becomes markedly reduced.
4. the buccal wall of the edentulous site will be diminished in both buccolingual/palatal direction and apicocoronal dimension
