Summary

The study aims to evaluate the efficacy of ridge preservation with collagen sponge or collagen membrane in combination with collagenated bovine bone mineral in extraction sockets of periodontally diseased teeth.

Detailed description

The study aims to evaluate the changes of clinical and radiographic outcomes following ridge preservation with collagen sponge or collagen membrane in combination with collagenated bovine bone mineral in extraction sockets of periodontally diseased teeth. The included patients will be randomized into two groups. The patients in control group will be treated with collagen membrane + collagenated bovine bone mineral, and those in the test group will be treated with collagen sponge + collagenated bovine bone mineral. The horizontal width of ridge, the vertical height of ridge at the buccal and palatal/lingual plates, width of keratinized tissue and thickness of mucosa will be measured before surgery and at 6 months postoperatively.

Conditions

• Periodontitis

Interventions

Type	Name	Description
PROCEDURE	alveolar ridge preservation	Alveolar ridge preservation and augmentation commonly are performed immediately after tooth extraction to preserve or increase ridge volume within or beyond the skeletal envelope that exists at the time of extraction.
