Horizontal Ridge Augmentation Utilizing a Composite Graft of Demineralized Freeze-Dried Allograft, Mineralized Cortical Cancellous Chips, and a Biologically Degradable Thermoplastic Carrier Combined With a Resorbable Membrane: A Retrospective Evaluation of 73 Consecutively Treated Cases From Private Practices

Abstract Ridge deficiency is an unfortunate obstacle in the field of implant dentistry. Many techniques are available to rebuild the deficient ridge. Some of these techniques are associated with significant morbidity and often require a second surgical site. With the advent of guided bone regeneration (GBR), one may now graft the deficient ridge with decreased morbidity and without a second surgical site. The purpose of this retrospective consecutive case series from 5 private practices is to report on the outcomes of a composite material of demineralized freeze-dried allograft, mineralized cortical cancellous chips, and a biologically degradable thermoplastic carrier (Regenaform RT) when combined with a resorbable membrane for GBR of lateral ridge defects in human patients. The specific aim was to quantify clinical results through direct measurement. Data were obtained from 73 consecutively treated lateral ridge augmentations performed on 67 partial and/or completely edentate patients. Clinical data (pre...
