Alveoli and Alveolar Ducts

Alveoli and Alveolar Ducts

The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...

Summary

A hemostatic sponge socket sealing technique effectively preserves horizontal bone dimensions and reduces post-operative pain compared to a gingival soft tissue punch. This method offers a less painful and cost-effective approach for alveolar ridge preservation after tooth extraction.

Background:

Alveolar ridge preservation is crucial after tooth extraction to maintain bone dimensions for future implant placement.
Dimensional changes in the alveolar socket can complicate subsequent restorative procedures.

Purpose of the Study:

To compare dimensional changes in alveolar sockets using two sealing techniques: demineralized bovine bone mineral (DBBM) with a gingival soft tissue punch (control) versus DBBM with a hemostatic gelatin sponge (test).
To evaluate post-operative pain associated with each technique.

Main Methods:

A pilot study involving 21 patients undergoing tooth extraction and implant placement.
Random allocation to either the control or test group for alveolar ridge preservation.
Digital impressions taken pre-operatively and 6 months post-operatively to measure horizontal and vertical dimensional changes.

Main Results:

No significant difference in vertical bone loss between the control (0.8 mm) and test (0.7 mm) groups.
Significantly less horizontal bone narrowing in the test group (4.8/2.3/1.3 mm at 1, 3, 5 mm levels) compared to the control group (7.1/4.0/2.5 mm at 1, 3, 5 mm levels).
Patients in the test group reported significantly lower post-operative pain (2.8/10) than the control group (5.7/10).

Conclusions:

The hemostatic sponge technique resulted in significantly better horizontal dimensional stability of the alveolar socket.
The hemostatic sponge technique led to significantly reduced post-operative pain.
This technique presents an effective, inexpensive, and less painful protocol for alveolar ridge preservation.
