New brochure shows Ridge Preservation with extended alveolar defects
The iMc Institute in Houston, USA, aims to carry out practice-relevant studies that really affect dental everyday life. The renowned network includes 14 clinicians in 11 practices. In 2015-16, the team of experts focused on the question of better protocols for the preservation of the alveolar ridge after tooth extraction: allograft and artificially cross-linked membrane? Or xenogeneic bone substitute material and collagen membrane without artificial cross-linking? 40 patients were treated at ten centers and followed up for six months. All showed highly damaged alveoli in the buccal dimension, caused by endo-periodontal lesions - a hardness test for regenerative materials.
A study that focuses on everyday clinical practice
The xenogeneic biomaterials from Geistlich clearly won the comparison - to the surprise of the US experts accustomed to allografts. Xenogeneic biomaterials were associated with significantly better soft tissue healing and increased volume gain with the same bone formation.1 More importantly, all implants were placed in the group treated with Geistlich products. In the allograft group, 14% of all cases required further bone augmentation. The study, which was awarded a prize by the American Academy of Periodontology (AAP), can be read in full here.
Ridge Preservation despite damaged bone
The new brochure "Geistlich Bio-Oss® Collagen and Geistlich Bio-Gide® in extraction sockets" summarizes the results of this study for the clinician. In addition, it illustrates with a clinical case how the crest volume can be maintained after tooth extraction despite a defective buccal bone wall.
