The Use of Selective Laser Melting in Mandibular Retrognathia Correction

Digitalization and additive manufacturing offer new possibilities in the of individualized medical dental products. In paper we present results first 30 consecutive growing patients (15 males 15 females), with a mean age 13.69 years (SD = 1.26), who were treated for mandibular retrognathia (skeletal Class II malocclusion), using fixed sagittal guidance (FSG) appliance, individually manufactured by selective laser melting (SLM). Lateral cephalometric radiographs taken before (T0) after (T1) treatment detailed analysis was performed. special focus on time period malocclusion correction. The analyzed data compared control group (CG; intermaxillary elastics) that matched pretreatment measurements. Both methods effective correction malocclusion, but significantly shorter (16.03 ± 1.09 months vs. 20.65 4.12 months) FSG appliance. After visual skeletal dentoalveolar effects achieved, statistically significant differences measured incisors inclination (0.45° 2.84° CG) distance (−0.61 mm 0.13 CG), molar (−1.07° 1.18° overbite (−3.82 −2.46 all favor final 16.03 months, (SNB angle, SNPg length (CoGn) consequently decrease ANB angle) as well vertical (lower anterior facial height (LAFH) gonial measurements noted, no reported complications. As needed comparable reports traditional use functional appliance cosmetical changes remained stable 2-year observational period, could benefit this type treatment. from
