Socket Preservation after Tooth Extraction: Particulate Autologous Bone vs. Deproteinized Bovine Bone

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Socket preservation techniques minimize post-extraction alveolar bone volume loss.
• Comparing deproteinized bovine bone graft with autologous bone graft is crucial for clinical decision-making.

Purpose of the Study:

• To compare the efficacy of deproteinized bovine bone graft versus autologous particulate bone graft in alveolar socket preservation.
• To evaluate volumetric changes in alveolar bone after tooth extraction using these two grafting materials.

Main Methods:

• A retrospective study of 21 patients undergoing socket preservation.
• Group A: Deproteinized bovine bone graft with collagen matrix.
• Group B: Autologous particulate bone graft from the mandibular ramus with collagen matrix.
• Cone beam computed tomography (CBCT) used for measurements before and after four months.
• Comparison of alveolar bone width (ABW) and height (ABH) reduction between groups.

Main Results:

• No statistically significant difference in ABW reduction between deproteinized bovine bone (Group A) and autologous bone (Group B) (p=0.28).
• No statistically significant difference in ABH reduction between deproteinized bovine bone (Group A) and autologous bone (Group B) (p=0.10).

Conclusions:

• Both deproteinized bovine bone graft and autologous particulate bone graft are effective for socket preservation.
• No significant difference in volumetric bone preservation was observed between the two grafting materials.
