20.500.12556/RUL-152305 Skeletal and dental effects of serial extractions performed with or without maxillary expansion a retrospective controlled study Objectives: The study aimed to compare severe crowding treatment's skeletal and dental effects by serial extractions or maxillary expansion and serial extractions in the mixed dentition phase. Setting and Sample Population: The retrospective controlled study included lateral cephalograms of 78 subjects aged 8.5 ± 1.4 years, 52 consecutively treated because of severe crowding, and 26 untreated controls matched for baseline age and observational period. Methods: Subjects were clustered according to the treatment modality, either serial extraction (EX) or expansion and extraction (EXP-EX) group. Sagittal and vertical skeletal as well as dental cephalometric parameters were assessed at baseline and after the eruption of all permanent posterior teeth, and group comparisons were performed. Results: Both treatment modalities significantly affected the vertical skeletal parameters in terms of decreasing the mandibular and occlusal plane inclination and increasing the facial height index. A distinct treatment effect on the gonial angle was observed, with a significant decrease in its superior part observed in both extraction groups. The annualized changes in the superior part of the gonial angle significantly differ (P= .036) between the Control (−0.04 ± 0.6), EX (−0.44 ± 0.6) and EXP-EX (−0.34 ± 0.5) groups. Upper and lower incisor inclination did not change significantly in any of the groups; however, the interincisal angle at follow-up was significantly smaller in the Control compared with both treated groups. Conclusions: Serial extractions and a combination of maxillary expansion and serial extractions have similar significant skeletal effects, mainly affecting vertical cephalometric parameters if performed during the pre-pubertal growth phase. alveolar bone micro-CT orthodontic tooth movement growth change maxillary expansion serial extractions alveolarna kost mikro-CT ortodontija premikanje zob true false true Angleški jezik Slovenski jezik Članek v reviji 2023-11-17 13:39:21 2023-11-17 13:39:27 2023-11-18 03:41:56 0000-00-00 00:00:00 2023 0 0 Str. 642-649 iss. 4 Vol. 26 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.31 1601-6343 10.1111/ocr.12647 147272195 Orthod_Craniofacial_Res_-_2023_-_Quinzi_-_Skeletal_and_dental_effects_of_serial_extractions_performed_with_or_without.pdf Orthod_Craniofacial_Res_-_2023_-_Quinzi_-_Skeletal_and_dental_effects_of_serial_extractions_performed_with_or_without.pdf 1 F6A05339ECE7FE73619792247A210126 a45183fb58fcf352e9b64ca1b9a2cce57cf42bb32bb9f47bcf07c9dcdbdb9a9d 7aedc546-8546-11ee-af1c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177738 https://onlinelibrary.wiley.com/doi/10.1111/ocr.12647 0 9274883c-8546-11ee-af1c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177739 Medicinska fakulteta 0 0 0
