Abstract: Background: This study aims to collect all current information regarding periodontal health parameters in patients treated with Invisalign and Fixed orthodontic appliances and integrate it into a meta analysis as an addition to existing literature. Methods: This meta analysis was registered on PROSPERO under CRD42023405976. The databases searched: PubMed (MEDLINE), Web of Science, Scopus , the Cochrane Central Register of Controlled Trials (CENTRAL) and Embase. The following indices were assessed for Plaque index (PI), Modified Plaque Index (MPI), Gingival index (GI), Gingival Bleeding Index (GBI), Sulcus Bleeding Index (SBI), Papillary Bleeding Index (PBI), Bleeding on probing (BOP) and Probing depth (PD). Methodological quality of included studies was assessed using Cochrane Collaboration Risk of Bias (ROB)-2 tool and New Castle Ottawa Scale (NOS). The statistical analysis was performed using RevMan (Version 5.3) (Cochrane Collaboration, Software Update, Oxford, UK) software. Standard Mean Difference (SMD) was used with random effects model with p<0.05 and 95% CI. Results: This meta-analysis comprised of eight studies with most of the studies being in the moderate risk zone. With clubbed data of forest plots, the SMD calculated indicates that all the periodontal parameters favour Invisalign over the conventional bracket appliance except for modified plaque index (MPI) which is also statistically significant (p<0.05). Conclusion: Invisalign is found to be significantly better that fixed appliance as far as periodontal parameters are concerned. More high quality studies are needed for fair conclusion.
