Are Bone Expansion Techniques Effective for Implant Placement in Narrow Alveolar Ridges?

Because of the fact that sufficient alveolar ridge bone is essential for the success of implant placement, the authors often face a challenge with augmenting residual maxillary alveolar ridges. The aim of the study was to compare the amount of ridge gain by the Osseodensification method with the manual bone expanders method for healed edentulous sites in the maxilla at different time intervals (immdiate postoperative and 6 mo postoperative). Two groups were equally and randomly divided with a total of 14 implants (Biohorizons) placed in the maxillary arch for 8 patients, osseodensification was used for 1 group (group 1), whereas manual threaded expanders (bone spreaders) was used for the other group (group 2).

Anterior Aesthetic Zone Reconstruction with Allogenic Bone Shell and Autogenous Bone Chips - An Evaluative Study.

Introduction: Horizontal alveolar bone loss hinders dental implant placement. Reconstruction of alveolar deficiency is mandatory to establish an ideal foundation for implant-supported prosthetic restoration. The aim of this study is to evaluate the regenerated bone following anterior aesthetic zone reconstruction with allogenic bone shell and autogenous chips.
