Abstract

The aim of this study was to evaluate the final vertical gain at the deficient anterior maxillary alveolar ridges using buccal versus palatal approaches for maxillary segmental sandwich osteotomy (inlay technique). This is a single-institutional randomized comparative clinical trial. The study population was 16 patients with edentulous anterior maxillary alveolar ridges (40 implant sites). Patients were randomly divided into two equal groups. Both groups received sandwich osteotomy with down fracture of the deficient anterior maxillary alveolar ridge, using buccal approach (control group) and palatal approach (study group) with interpositional alloplastic bone blocks fixed with miniplates. Assessment included the mean percentage of vertical gain at the proposed implant sites after 4 months, taken from cross-sectional cuts of a cone beam computed tomography. All cases showed uneventful wound healing and a total of 40 delayed implant placement were done. Results showed that there was no statistical significance between the 2 groups in terms of bone height (P = .43) and labial prominence (P = .5) CONCLUSION: Both techniques were successful where the mean percentage of 4 months postoperative vertical bone gain of the control group ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
