{"doi":"10.1111/ocr.70051","title":"Nasoalveolar Molding in Unilateral Cleft Lip and Palate: A Three‐Dimensional Analysis","abstract":"OBJECTIVES: This study aimed to three-dimensionally analyse the effects of pre-surgical nasoalveolar molding (NAM) in patients with unilateral cleft lip and palate. METHODS: The sample consisted of 66 patients (with pre- and post-NAM casts), collected from three centres. Landmarks and measurements were identified on each cast, and the changes from pre- to post-NAM were recorded and analysed using a paired t-test. RESULTS: Post-NAM, we observed a mean decrease of 5.18 mm in 3D cleft width, a 1.78 mm decrease in the sagittal cleft gap, a 1.34 mm decrease in the anterior arch width and a 2.27 mm increase in the posterior arch width. There was a greater inward rotation of the greater segment (8.50°) compared to the lesser segment (3.09°), an increase in arch depth (1.74 mm) and internal flexion (9.20°) of the lesser segment. No statistically significant changes in the greater segment's arch depth and internal flexion were observed. The morphological changes between pre- and post-NAM therapy were visualised by the closest-distance colour maps and 3D superimposition assessments. CONCLUSIONS: This study demonstrated the significant morphological changes induced by pre-surgical nasoalveolar molding (NAM) in patients with unilateral cleft lip and palate through a three-dimensional analysis. There was a notable reduction in cleft width, inward rotation of the greater segment and changes in arch dimensions.","journal":"Orthodontics and Craniofacial Research","year":2025,"id":537001,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.7424,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1422347,"name":"Yong Jong Park","orcid":"0000-0002-1933-9835","position":1,"is_corresponding":false},{"id":1422818,"name":"Olivia Yue","orcid":null,"position":2,"is_corresponding":false},{"id":266789,"name":"Marília Yatabe","orcid":"0000-0002-8748-6714","position":3,"is_corresponding":false},{"id":660439,"name":"Heesoo Oh","orcid":"0000-0002-6029-6064","position":4,"is_corresponding":false},{"id":266793,"name":"Lucía Cevidanes","orcid":"0000-0001-9786-2253","position":5,"is_corresponding":false},{"id":1422819,"name":"Meghan Hansen","orcid":null,"position":6,"is_corresponding":false},{"id":1422820,"name":"Sophia Dipietro","orcid":null,"position":7,"is_corresponding":false},{"id":266781,"name":"Jonas Bianchi","orcid":"0000-0002-3749-0918","position":8,"is_corresponding":false},{"id":1422817,"name":"Yoon Weon Suh","orcid":null,"position":0,"is_corresponding":true}],"reference_count":15,"raw_metadata":null,"created_at":"2026-07-19T02:52:09.056872Z","pmid":"41147865","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
