Expansion of the alveolar bone crest in two stages: two clinical cases

Abstract Alveolar crest expansion is a surgical approach used to remedy width defects and represents a predictable alternative procedure to guided tissue regeneration and autologous onlay grafts. Clinical and experimental results underscore the benefits of non‐mechanical implant bed preparation in bones with very low density. We report two clinical cases in which crest expansion was conducted in two stages: corticotomies in alveolar crest and then, after a 28‐day interval, crest expansion and implant placement, permitting revascularisation of the buccal cortical bone.
