Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to evaluate the safety of placing TiO2 scaffolds in alveolar ridge and to evaluate if the scaffold material contributes to maintain the anatomy and the volume of the alveolar process after tooth extraction.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objective of the clinical trial is to evaluate the safety of placing TiO2 scaffolds in alveolar ridge.

The secondary objectives are; (1) to assess anatomical changes as measured by intraoral digital scanning at the time of extraction, after 6 months. (2) to evaluate soft tissue inflammation at 1, 2, 4, 12 and 24 weeks post-surgery, (3) to assess the preservation of the alveolar ridge following placement of TiO2 scaffold in the alveolae after tooth extraction, (4) to assess bone mineralization and quantitative healing in bone biopsies obtained at implant installation in the preserved site 6 months following treatment.
