Trial Summary

Do I need to stop my current medications for the trial?

The trial does not specify if you need to stop taking your current medications. However, if you are taking medications that affect bone remodeling, like bisphosphonates or RANK-L inhibitors, you may not be eligible to participate.

What data supports the effectiveness of the treatment Mix of Demineralized Freeze-Dried Bone Allograft and Deproteinized Bovine Bone Mineral for alveolar ridge preservation?

Research shows that using demineralized freeze-dried bone allograft (DFDBA) and deproteinized bovine bone mineral (DBBM) can help maintain the shape and size of the jawbone after tooth extraction, which is important for future dental procedures. These materials are used to fill the space left by the extracted tooth, helping to preserve the bone structure.12345

Is the combination of demineralized freeze-dried bone allograft and deproteinized bovine bone mineral safe for humans?

The studies suggest that using demineralized freeze-dried bone allograft (DFDBA) and deproteinized bovine bone mineral (DBBM) in dental procedures like alveolar ridge preservation and sinus augmentation is generally safe, as they are commonly used materials in these contexts without reported safety issues.12356

How is the Mix of DFDBA and DBBM treatment different from other treatments for alveolar ridge preservation?

The Mix of DFDBA and DBBM treatment is unique because it combines two different bone graft materials to preserve the alveolar ridge after tooth extraction, potentially offering the benefits of both materials. This combination aims to limit bone loss and maintain the ridge's shape, which is important for future dental implants.14578

What is the purpose of this trial?

This trial tests a new grafting material made from processed human and cow bones to help preserve the jawbone after tooth removal. It targets patients who need a premolar extraction and plan to get a dental implant. The cow bone part helps maintain the jaw's shape, while the human bone part encourages new bone growth. The use of bovine bone matrix in bone grafting has shown good results in bone and volume preservation after tooth extraction.

Findings from Research

A study involving 42 patients showed that a combination allograft of 70% mineralized and 30% demineralized freeze-dried bone allograft (FDBA) resulted in significantly greater new bone formation (36.16% vital bone) compared to 100% mineralized FDBA (24.69% vital bone).
Both graft types provided similar dimensional stability of the alveolar ridge, indicating that the combination allograft is more effective for bone regeneration without compromising the structural integrity of the ridge.
Histologic healing following tooth extraction with ridge preservation using mineralized versus combined mineralized-demineralized freeze-dried bone allograft: a randomized controlled clinical trial.Borg, TD., Mealey, BL.[2022]
Demineralized freeze-dried bone allograft (DFDBA) is effective in maintaining the dimensional stability of the alveolar ridge around dental implants, potentially leading to a higher percentage of new vital bone compared to mineralized alternatives.
Using DFDBA in large horizontal gap defects at molar implant sites, along with protective measures like dense polytetrafluoroethylene membranes, can help ensure successful healing and minimize leftover biomaterial around the implant.
Protocol for Maintaining Alveolar Ridge Volume in Molar Immediate Implant Sites.Johnson, TM., Berridge, JP., Baron, D.[2020]
In an in vitro study using porcine osteoclasts, DFDBA with 2.41% residual calcium significantly increased resorptive activity compared to other calcium levels, suggesting it may be optimal for bone regeneration.
The study highlights the importance of residual calcium levels in DFDBA, as varying degrees of demineralization can affect the osteoclast activity and, consequently, the effectiveness of DFDBA in periodontal therapy.
