This study presents the histomorphometric results of the Wafer Technique, which is based on guided bone regeneration and onlay grafts for 3D bone augmentation. This two-stage technique utilizes autogenous cortical bone plates and collagen membranes, forming a barrier containing a mixture of deproteinized bovine bone matrix, autologous blood, and bone grafted from intraoral sites. Twelve patients were treated. At 6 months postsurgery, histologic analysis of the regenerated areas revealed the presence of compact newly formed bone with no sign of inflam- mation. The percentages of new bone and native bone (mineralized tissue) were 16.4% (95% CI: 9.5% to 23.2%) and 42.6% (95% CI: 28.2% to 57.0%), respectively. Twenty-five implants were placed. The procedure has been proven to be safe and reliable, and only one transient complication was observed.
