Preservation of Alveolar Ridge using Graft Material after Tooth Extraction: A Clinical Trial

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• The alveolar process remodels significantly after tooth extraction.
• Ridge preservation techniques aim to mitigate post-extraction bone loss.

Purpose of the Study:

• To evaluate hard and soft tissue changes in postextraction sockets.
• To compare outcomes with and without bone graft material application.

Main Methods:

• 40 patients undergoing anterior tooth extraction were divided into control and experimental groups.
• The experimental group received beta-tricalcium phosphate allograft bone material.
• Cone-beam computed tomography (CBCT) assessed linear and volumetric changes at 14 weeks.

Main Results:

• The experimental group showed statistically significant preservation of buccal and lingual plate height (P = 0.023).
• No significant difference in bone height was observed in the control group.
• Baseline measurements showed no significant differences between groups.

Conclusions:

• Alveolar ridge preservation with beta-tricalcium phosphate offers therapeutic benefits.
• This technique effectively limits bone resorption compared to simple extraction.
• The findings support the use of bone graft materials for maintaining alveolar ridge dimensions.
