Alveolar Ridge Augmentation With Allograft Stem Cell–Based Matrix and Titanium Mesh

Abstract

Introduction: When bone surrounding a proposed implant site is deficient in both a vertical and horizontal dimension, bone augmentation procedures using titanium mesh can be used. Although there are multiple reports of titanium mesh use with a variety of graft materials, to our knowledge, this presentation is the first to show use of a stem cell–based titanium mesh augmentation.Case Presentation: After the removal of a failing maxillary subperiosteal implant, significant atrophy of the maxillary alveolus was evident. After bilateral sinus augmentation with an allograft‐derived stem cell–based matrix (cellular allograft), four posterior implants were placed. In preparation for future anterior maxillary ridge augmentation, an interim denture supported by the posterior implants and O‐ring attachments was fabricated. The anterior titanium mesh‐supported cellular allograft was placed and allowed to heal for 4 months, followed by placement of four additional implants. After 4 months of integration, the patient was restored with a locking milled bar denture.Conclusion: The use of a cellular allograft with titanium mesh for stabilization can result in significant horizontal and vertical augmentation for implant reconstruction.
