PRIMARY outcome

Timeframe: 3 years after implant placement

Population: 11 subjects from Group A (Implant placement 3 months after tooth extraction), 8 subjects from Group B (Implant placement 6 months after tooth extraction), and 7 subjects from Group C (Implant placement 9 months after tooth extraction) did not attend this visit/were lost to follow-up/were excluded from the study, so data was not collected.

For participants that had implant placement, this outcome is determined via clinical evaluation of the number of participants that still had their 1 implant in place after 3 Years. Note: Only 1 implant was placed per participant.

SECONDARY outcome

Timeframe: 3 months, 6 months, 9 months

Population: One bone biopsy in group A (Alveolar ridge preservation using xenograft and implant placement at 3 months) was too deteriorated for histological processing, so it was discarded.

After histological staining, median percent of mineralized tissue (vital bone) was calculated by appearance using ImageJ (NIH, open-source software).

SECONDARY outcome

Timeframe: 3 months, 6 months, 9 months

Population: One bone biopsy in group A (Implant Placement 3 Months After Tooth Extraction) was too deteriorated for histological processing, so it was discarded.

Median percentage of non-mineralized tissue: Following histological staining, the percentage of non-mineralized tissue was calculated using ImageJ (NIH, open-source software). The total tissue area was measured, and the percentages of mineralized tissue and residual xenograft material were subtracted from the total area. The remaining area was reported as the percentage of non-mineralized tissue.

SECONDARY outcome

Timeframe: Baseline, Final Follow-Up (4 weeks before implant placement)

When compared to baseline, determine if there is a change in median bone width reduction (at 1, 3, 5mm apical to bone crest) for each group (implant placement 3 months after tooth extraction, implant placement 6 months after tooth extraction, implant placement 9 months after tooth extraction), which will be measured using clinical and radiographic (via CBCT) assessment. To calculate change, the final follow-up value for each group is subtracted from the baseline value.

Measured in millimeters based on standardized intra-oral radiographs at crown placement and 3 years after crown placement. Negative values depicts bone levels below fixpoint (implant platform) meaning "true" bone loss. Positive values denotes bone levels above fixpoint meaning minimum remodeling following implant placement.
