ABSTRACT
AIM: The aim of this systematic review was to systematically assess the papers comparing the surgical techniques of Alveolar Distraction Osteogenesis(ADO) and Autogenous Bone grafting (ABG) for Vertical Ridge Augmentation in terms of bone gain, bone resorption and incidences of complications.
METHOLODOLOGY: The review was registered on PROSPERO with the ID : CRD42021237671. A broad electronic survey was conducted in the PubMed, Scopus, Web of Science, Cochrane Library, and Virtual Health Library databases of all studies published till 08/03/2022. Four studies fulfilled the criteria to carry out a meta-analysis a in which a total of 58 patients underwent ADO and 43 patients for ABG. A total of 133 implants were placed in the ABG group and 124 in the ADO group.
STATISTICAL ANALYSIS: DerSimonian-Laird estimator of variance was used for Random effect meta-analysis. The estimates of an intervention were expressed as the odds ratio (OR) and standard mean difference (SMD) in millimeters.
RESULTS: There was statistically significant difference in terms of bone height gain with SMD of – 0.78 (95% 0.04-1.55) in ABG. Bone resorption and complications were statistically insignificant with SMD of 0.52 (95% – 1.59 to 0.56) and OR 0.55 (95% 0.18-1.70), respectively.PROSPERO Registration ID: CRD42021237671.
