Evaluation of Vertical Height in Anterior Maxillary Sandwich Osteotomy: Simultaneous Versus Delayed Implant Placement

Vertical bone height has always presented challenge for the clinicians especially in the anterior aesthetic zone. Therefore, this trial will attempt to compare whether better vertical bone height and implant placement technique can be achieved using simultaneous implant placement with the sandwich osteotomy, which is a time saving procedure performed in a single stage surgery; when compared to using fixation plates to support the segment followed by delayed implant placement.
