Non-extraction camouflage on a fully cooperative full-step class II division 2 adult patient treated with en-masse distalization, class II elastics and preadjusted lingual appliance: A case report.

This article describes one adult bilateral full-step class II case with severe initial upper incisors retroclination successfully treated by a completely invisible lingual appliance. A non-extraction treatment to compensate for the severe sagittal discrepancy was made possible following the excellent patient cooperation with intermaxillary elastics, combined with upper arch en-masse effective distalization with miniscrews. The application of an auxiliary torque spring was essential to increase upper incisors torque during class II mechanics.

Clinical and biological underpinnings of longitudinal atrophy pattern progression in Alzheimer's disease.

Background: Magnetic resonance imaging (MRI) has recently enabled to identify four distinct Alzheimer's disease (AD) subtypes: hippocampal sparing (HpSp), typical AD (tAD), limbic predominant (Lp), and minimal atrophy (MinAtr). To date, however, the natural history of these subtypes, especially regarding the presence of subjects switching to other MRI patterns and their clinical and biological differences, remains poorly understood.

Objective: To investigate the clinical and biological underpinnings of longitudinal atrophy pattern progression in AD.

Invisible treatment with preadjusted lingual appliance and monolateral space opening for an adult Class II malocclusion with upper lateral incisors agenesis: An ortho-prosthetic case report.

This case report describes the treatment of a Class II malocclusion with upper lateral incisors agenesis in an adult patient, performed by an invisible preadjusted lingual appliance, monolateral space opening and dental Class II correction. The patient had previously been treated by clear aligners with the insertion of an implant in upper right canine position in order to close the remaining space. With the twofold aim of obtaining ideal occlusal relationship and smile aesthetic improvement, it highlights how a fixed orthodontic technique is needed to achieve the planned results, when anterior torque, bodily translations and deep-bite correction are necessary.

Soft tissue changes during orthopedic therapy: An in vivo 3-dimensional facial scan study.

Introduction: The aim was to compare the soft tissue changes in pretreatment and posttreatment facial scans of patients who had undergone various orthopedic treatments vs a control group of untreated growing patients.

Methods: Facial scans were performed before (T0) and after (T1) orthopedic treatment in 15 patients prescribed rapid palatal expander (RPE), 15 cervical headgear (HG), and 15 facemasks (FM), as well as 6 months apart in 15 untreated growing patients. After best-fit scan alignment using Geometric Control X software (3D Systems Inc, Rock Hill, SC), a 3-dimensional (3D) analysis of soft tissue changes was performed, comparing 3D reference points (total 22) and 8 areas on T0 and T1 scans.
