INTRODUCTION: Dental pulp may respond differently to adverse orthodontic forces. Major physiological effects of optimum force application on dental are vascular pulpal changes, calcification, and fibrosis. Functional appliances taking anchorage from the dentition tend exert reciprocal higher OBJECTIVE: To evaluate 3D volumetric changes coronal maxillary mandibular permanent first molars 6 months after AdvanSync TM fixed functional Twin Block removable appliance therapy followed at 18 treatment (T2). MATERIALS AND METHODS: This retrospective study was performed CBCT records obtained a previous prospective (Randomized Clinical Trial) comprising 32 patients [females: 17 (9.0–14.5 years), males: 15 (10.5–15.0 years)] who underwent advancement with (group 1) 2). Pretreatment (T0), (T1), (T2) follow-up were assessed for volume by using ITK-SNAP software version 3.2. RESULTS: Intragroup showed significant decrease in #16, #26, #36 time intervals T0–T1, T0–T2, T1–T2 groups 1 2. Intergroup comparison #16 #26 statistically T1. A #46 observed both groups. CONCLUSION: tends molar volume.
