The Lower Lip Profile Change During Total Distalization of the Mandibular Dentition

Objectives: This study aimed to determine the factors influencing lower lip profile during Class III total arch distalization camouflage treatment. Methods: The cohort included 45 patients diagnosed with skeletal class malocclusion. These underwent orthodontic treatment distalization. Lateral cephalograms were taken at pretreatment and posttreatment stages. Cephalometric measurements analyzed unravel of profile. defined new variables, i.e ., CK CKA, for detailed soft tissue analysis. Results: Novel presented in this showed statistically significant changes after angle L1 A Pog, NB, IMPA correlated. Simple regression analysis was performed between variables. formula ΔCKA = 0.79(Δ NB) -1.6, multiple resulted 0.5(Δ – 0.42 (‘LL Eline’, before treatment). Conclusion: present provided evidence that evaluations, including novel CKA CKHA, significantly related mandibular incisor position dentition. results demonstrated clinically retraction could be obtained. Therefore, non-extraction must suggested as first option mild malocclusion patients.
