Trial Summary

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 data supports the effectiveness of the treatment Bio-Oss Collagen for tooth loss?

Research shows that Bio-Oss Collagen, used in bone grafting, can help with bone regeneration and improve periodontal (gum) health. Studies have found it effective in reducing probing depth and gaining clinical attachment, which are signs of improved gum and bone health after tooth extraction.12345

Is Bio-Oss Collagen Graft safe for humans?

Bio-Oss Collagen has been used in various dental procedures, and studies have not reported significant safety concerns, suggesting it is generally safe for human use.12367

How is the Bio-Oss Collagen treatment for tooth loss different from other treatments?

Bio-Oss Collagen is unique because it uses a natural bovine bone mineral that helps in bone conduction, promoting bone growth in areas where teeth have been lost. This treatment is often combined with a collagen membrane to enhance periodontal regeneration, making it different from other treatments that may not use these specific materials or methods.128910

What is the purpose of this trial?

The purpose of this study is to clinically, radiographically and histologically evaluate the healing sequence of post-extraction sockets grafted with Bio-Oss Collagen® at 3, 6 and 9 months following tooth extraction in single-rooted tooth sites.Subjects with single rooted teeth planned for extraction and replacement with endosseous dental implants will be recruited for the study based on the eligibility criteria and will be divided in three groups (Groups 1, 2 and 3).A cone-beam computed tomography (CBCT) scan will be obtained and reviewed to prepare for the surgical approach and evaluate the ridge dimensions, the tooth planned for extraction as well as the adjacent sites. After tooth extraction, the socket will be grafted with Bio-Oss Collagen® and, depending on the morphology of the extraction sockets, a collagen matrix (Mucograft® seal) and/or a restorable collagen membrane (BioGide®)will be placed to cover and stabilize the graft. Patients will return at 2 and 6 weeks post-extraction to evaluate the healing. A second CBCT will be obtained 2 weeks prior to implant placement to evaluate the ridge dimensions and compare them to the baseline data. Implant placement will take place at 12, 24 and 36 after tooth extraction for Groups 1, 2 and 3 respectively. A bone core biopsy will be obtained at the time of implant placement and will be sent for histological analysis. Patients will return for a post-operative visit at two weeks. Clinical indices (probing depth, recession, bleeding upon probing, keratinized mucosa height, plaque and gingival index), patient reported outcomes and marginal bone levels via standardized periapical radiographs will be evaluated and recorded at baseline (no more than 30 days following delivery of final implant restoration) 1, 2 and 3 years post-loading.

Eligibility Criteria

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.

Inclusion Criteria

Subjects must have read, understood and signed an informed consent form
My tooth extraction site has intact walls or only one side is partially missing.
I am healthy enough for dental surgery, including tooth removal and implants.

Exclusion Criteria

I am willing to attend all required visits.
I do not have major health issues that could affect treatment or healing.
I am not on long-term medications that affect bone health.

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.
