Clinical Trial: Clinical Efficacy Assessment of Digitally Fabricated PEEK Barrier Membranes for Guided Bone Regeneration in Severe Bone Defects

U.S., Nov. 6 -- ClinicalTrials.gov registry received information related to the study (NCT07918131) titled 'Clinical Efficacy Assessment of Digitally Fabricated PEEK Barrier Membranes for Guided Bone Regeneration in Severe Bone Defects' on Oct. 31.

Brief Summary: 1. Research background: Guided bone regeneration (GBR), as a bone augmentation technique, is widely used for the reconstruction of hard-tissue defects in implant dentistry. Terheyden classified bone defects into four types according to the spatial relationship between the defect and the intended implant site. Among these, type 2/4, 3/4, and 4/4 are recommended to be managed with a staged protocol: bone augmentation first, followed by dental implant placement. The selection of barr...
