Using Xenograft Combined With Barrier Membrane to Improve the Formation of

Status Recruiting

Clinical Trial Summary

To evaluate the clinical effect of site preservation after third molars extraction by using tooth extraction of third molars with site preservation using bio-oss and bio-guide in preventing the formation of deep periodontal pockets in the distal of second molars.

Clinical Trial Description

The mandibular third molar is the last tooth to erupt in the dentition, and due to the insufficient eruption position, it can lead to different degrees of impact. During the eruption of impacted tooth, the crown may be partially or completely covered by the gingival flap. A deep blind pocket is formed between the gingival flap and the tooth crown, and food and bacteria are easily impinged in the blind pocket. Under the influence of oral environment and dental plaque, the presence of blind pockets can lead to the loss of periodontal attachment and the absorption of alveolar bone, thus affecting the distal periodontal status of adjacent molars. Organic bone xenograft material composed of absorbable organic bovine hydroxyapatite is one of the commonly used transplantation materials for repairing bone defects. The application effect of allogeneic bone materials in periodontal therapy has been recognized by many experts and scholars. Guided bone regeneration (GBR), as a conventional periodontal bone graft, has achieved good results in periodontal tissue regeneration. Aljuboori et al. found that when the third molar was removed and GBR was performed at the same time, the depth of distal periodontal pocket probing of the adjacent second molar was significantly reduced in the re-examination 6 months after surgery. Hence, this study intends to use xenograft combined with barrier membrane to improve the formation of distal periodontal pocket of the second molars after third molars extraction. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
