Designing prequalified connections is a process of iterative calculation, in which certain dimensions are varied until the verifications and restrictions stipulated by the standard are met. This is a slow process that can be automated using various software and optimized using a new design method called generative design, which consists of establishing restrictions so that the script delivers multiple solutions that meet the objectives. This research was conducted based on the design science research (DSR) methodology and focused on developing a method to design moment-resisting steel connections, specifically end-plate connections, using generative design in a building information modeling (BIM) environment. From this, it was possible to obtain several end-plate connection design alternatives, and technical validation was carried out to verify the functionality of the program using a verification method proposed by a civil engineer.

ABSTRACT:To treat initial caries lesions using the technique of resin infiltration for a restoration of natural enamel appearance. Case report of a 19 year old female who presented with moderate post-orthodontic white-spot lesions (WSLs) at the upper central and lateral incisors following two years of active treatment with a fixed orthodontic appliance, and requested an aesthetic improvement of decalcified enamel surfaces. The technique of resin infiltration (Icon®, DMG, Hamburg, Germany) is presented as a means for not only inhibiting lesion progression, but also for an adequate rehabilitation of dentofacial esthetics. Practical tips and cues for clinical handling of the infiltration technique are provided. Resin infiltration augments the therapeutic spectrum for orthodontist as well as pediatric or general dentists in that enamel areas affected by post-orthodontic WSLs can be restored to their original appearance.KEY WORDS: white spot lesion, resin infiltration, Icon, camouflage effect.
