Horizontal guided bone regeneration on knife-edge ridges: A retrospective case-control pilot study comparing two surgical techniques.

Introduction: Studies evaluating guided bone regeneration (GBR) on knife-edge ridges using absorbable membranes with staged approaches have reported various horizontal bone gains. This study compared the horizontal bone gain obtained via a conventional technique of GBR and a recently-reported technique. Bone loss during the healing process was also measured.

[Collaboration between periodontics and orthodontics: interest of alveolar corticotomies and piezocision. Review of literature].

Introduction: Orthodontics in adults must adapt to certain particularities especially related to the decrease or absence of growth and the prevalence of periodontal damage in this population. This review of the literature aims to assess the effects of alveolar corticotomies on accelerating or facilitating tooth movements in different types of orthodontic movements, to compare results obtained by classical technique with those obtained by piezocision and analyze their impact on periodontal tissues in the long term.

Material And Methods: Research was performed with Medline, Embase and Cochrane databases, beginning in January 2000.
