Bone resorption after a tooth extraction is a generally accepted knowledge and has been demonstrated by many animal and human studies. Especially during the first three months followed by the tooth extraction, the volume of bone may change significantly without any interference. Thus, doing a ridge preservation procedure following the extraction is a common standard of care method to maintain the socket volume if implant placement is considered as a treatment option in the future. A variety of materials and methods have been used for ridge preservation. However, it's still inconclusive to determine the best material to maintain the ridge dimension, especially for membrane placement that allows for space maintenance to protect the grafting material. Furthermore, there is no evidence to show any treatment rationale is superior to any other ridge preservation method.
In general, the membrane serves the function of the barrier and space protector. The periodontal surgeon use membranes to exclude the epithelium growth and to limit the collapse of the soft tissue into the healing alveolar socket. Regarding resorbable and non-resorbable membrane materials, both serve the function of protecting the graft material from the oral cavity. However, there are also many demonstrating that without membranes the extraction socket healed nicely without any interferences. The question to us is: Do we need the membrane to exclude the epithelium or any kind of surgical dressing material is sufficient enough to preserve the volume of the extracted ridge?
The object of this study is to compare five popular membranes on the market that present different characteristics of the membranes.
The extraction and the grafting procedure involved in this study are standard of care. The investigators will extract the hopeless teeth and prepare the site for implant placement in 4 months.
The following products will be used during the study:
* Collatape (Zimmer Dental)- approved by the FDA (class III)
* Cytoplast (Osteogenics Biomedical)- cleared by the FDA
* OssixPlus (Dantum Dental)- cleared by the FDA
* Renovix-Plus (Salvin)- cleared by the FDA
* BioXclude (SNOASIS)-certificate from the American Association of Tissue Banking
* PuroⓇ, Zimmer Dental)- cleared by the FDA
* RegenerOssⓇ, Zimmer Dental) - cleared by the FDA
During the appointment for the implant placement. A bone core from all subjects in each treatment group will be collected from the augmentation site instead of drilling away. The sample will be evaluated for the following:
* % viable of bone
* % of connective tissue
* % of residual graft material
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Collatape (Zimmer Dental) | Procedure: Tooth extraction and ridge preservation using different barrier mermbranes | This material is a resorbable collagen wound dressing. They are made from bovine Achilles tendons and are a source of Type I collagen. The resorbable wound dressings are sterilized after purification with ethylene oxide. | |
| Cytoplast Barrier Membranes TXT-200 Singles (Osteogenics Biomedical) | Procedure: Tooth extraction and ridge preservation using different barrier mermbranes | Cytoplast Barrier membranes are manufactured from high-density Polytetrafluoroethylene (PTFE) which allows them to withstand exposure to the oral environment. The textured surface increases the surface area available for cellular attachment during dental bone grafting procedures thereby aiding in stabilizing the PTFE membrane. It can be removed non-surgically after at least 21 days. | |
| Ossix Plus (dantum dental) | Procedure: Tooth extraction and ridge preservation using different barrier mermbranes | OssixPlus is a resorbable collagen dental membrane used for Guided Bone Regeneration and Guided Tissue Regeneration. It contains a patented GLYMATRIX cross-linking technology that allows it to maintain barrier functionality for 4 to 6 months. The collagen is derived from porcine. | |
| Renovix-Plus (Salvin) | Procedure: Tooth extraction and ridge preservation using different barrier mermbranes | Renovix Plus is a non-cross-linked extracellular matrix containing Type I, II, and III Collagen, Fibronectin, Laminin, and Elastin. It provides architecture and barrier protection for bone regeneration and soft tissue esthetics. This membrane resorbs within six months. | |
| BioXclude (Snoasis) | Procedure: Tooth extraction and ridge preservation using different barrier mermbranes | BioXclude is a minimally manipulated allograft amnion chorion tissue. It is obtained from consenting mothers who donate their placentas after elective caesarian section delivery. The tissue is processed to cleanse and maintain the tissue. Following processing and dehydration, the allografts are packaged and terminally sterilized. |
