What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how well Bio-Oss Collagen, a bone graft material, aids healing after the removal of a single-rooted tooth. The research aims to assess the graft's impact on recovery at 3, 6, and 9 months post-extraction, before placing a dental implant. Participants will be divided into three groups based on when they receive their implant, helping researchers determine the best timing for implant placement. The trial seeks individuals who need a single-rooted tooth removed, plan to replace it with an implant, and have no major health issues affecting healing. As an unphased trial, it offers participants the chance to contribute to understanding optimal recovery and implant timing.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking medications that affect bone metabolism, like certain bisphosphonates or glucocorticoids.

What prior data suggests that Bio-Oss Collagen is safe for use in dental procedures?

Research has shown that Bio-Oss Collagen® is generally safe and well-tolerated for dental procedures. Made from cow bone, it undergoes careful cleaning to ensure safety. Studies have found it to be biocompatible, meaning it integrates well with the body without causing harm.

When used to preserve bone after tooth removal, Bio-Oss Collagen® has proven effective. In over 90% of cases, it maintains good bone structure without requiring additional bone grafts. Although specific side effects are not detailed, its approval for dental use by health authorities indicates its safety.¹ ² ³ ⁴ ⁵

Why are researchers excited about this trial?

Unlike traditional bone grafts that often rely on autografts or allografts, Bio-Oss Collagen is a xenograft, meaning it's derived from animal sources. This makes it unique because it can potentially reduce the need for a second surgical site, which is typically required to harvest bone for autografts. Researchers are excited about Bio-Oss Collagen because it combines bovine-derived bone mineral with collagen, which may enhance bone regeneration and support better implant stability. Additionally, this treatment offers flexibility in timing for implant placement, allowing for personalized treatment plans based on patient needs.

What evidence suggests that this trial's treatments could be effective for tooth loss?

Studies have shown that Bio-Oss Collagen effectively preserves bone around teeth after extraction. Research indicates it significantly reduces bone loss, stabilizing the area for future dental implants. One study found that Bio-Oss Collagen reduced bone loss by about 2.37 mm, keeping the bone healthier and more intact compared to not using the graft. Overall, Bio-Oss Collagen has proven to be a reliable option for maintaining bone structure post-extraction. Participants in this trial will receive Bio-Oss Collagen with implant placement at different intervals after tooth extraction to assess its effectiveness over time.⁴ ⁶ ⁷ ⁸ ⁹

Are You a Good Fit for This Trial?

This trial is for adults needing a single-rooted tooth (not mandibular incisors) extracted and replaced with an implant. Candidates should be in good health, able to undergo dental procedures, and willing to sign consent. Exclusions include severe bone diseases, significant organ impairments, heavy smokers, pregnant or nursing women, those on certain medications affecting bone metabolism.

What Are the Treatments Tested in This Trial?

Interventions

Bio-Oss Collagen

Trial Overview The study tests how well the Bio-Oss Collagen® graft aids healing after tooth extraction at different intervals: 3, 6, and 9 months. Participants are divided into three groups; each group receives implants at different times post-extraction (12, 24 or 36 weeks), followed by evaluations including CBCT scans and biopsies.
