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).

The Use of Computer-Guided Half Propeller Genioplasty for the Correction of Mandibular Asymmetry (A Mandibular Orthognathic Surgery Without a Condylar Intervention Technical Strategy).

Introduction: Mandibular asymmetry is a facial deformity that results from multiple causes; among these are growth deficiency like hemifacial microsomia and growth excess as in condylar hyperplasia. The facial asymmetry caused by condylar hyperplasia has been treated over the years with different surgical and nonsur-gical modalities dependent on the age of the patient and the severity of the condition. The authors in this article introduce a modified version of the propeller genioplasty technique.
