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

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Scaffold
After tooth extraction will one scaffold be placed in the extraction alveola, covered by a membrane and then covered by the gingival tissue.
Scaffold placement
The scaffold is placed in the alveola following extraction
CBCT
A Cone Beam Computer Tomography (CBCT) is taken of the area of interest after surgery
