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

摘要

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: corticomies in alveolar crest and then, after a 28-day interval, crest expansion and implant placement, permitting revascularisation of the buccal cortical bone.
