Abstract

Objective: This systematic review aimed with the primary goal to analyse recent evidence on anchorage loss, amount of distalization, distal tipping in distalization appliances. Background: A comprehensive search of key databases, including MEDLINE/PubMed, Scopus, Cochrane, and EMBASE. Studies published from the year 2000 to 2023 were considered with no language restriction. Aim was to include all the recent studies to make this review more relevant to current paradigm of orthodontic distalization mechanics. Relevant keywords were used, and risk of bias evaluated for included studies. Adults or adolescent patients exhibiting Angle’s Class II molar relationship formed the study population with a minimum sample size of 10 patients. Patients with periodontal compromise and those treated with mini-plates and extraoral appliances were excluded. Various distalization appliances including mini-screw supported appliances were examined. Materials & Materials: A search across databases yielded a total of 284 records. Additionally, 17 records were identified through other sources, resulting in a combined pool of 301 records. 11 studies met the inclusion criteria and were included in this review. The studies include both the conventional distalization appliances as well as the skeletally anchored appliances. Results: Qualitative analysis and results of the included studies have been highlighted. Conclusion: Bone-anchored supported distalization appliances were found to offer significant advantages over conventional appliances in terms of better anchorage control, reduced treatment time and favourability in critical anchorage cases. Modification of pendulum and distal jet appliances by incorporation of micro implants significantly preserves anchorage and reduces overall treatment time
