Three-dimensional (3D) mini plate systems are used in the treatment of mandibular fractures. The system is advantageous in comparison to conventional plates due to the stabilization of tension and compression areas, improved initial stability, and biomechanical behavior. The aim of this retrospective study was to evaluate the use of a 3D miniplate system for the treatment of patients with mandibular fractures. Patients with mandibular fractures treated with a 3D plate system at the Department of Oral and Maxillofacial Surgery, University Hospital Münster, during a period of 5 years, were included in this study. Mandibular fracture conditions and minor and major post-operative complications were reported. In total, 336 patients and 391 mandibular fractures were assessed. The most common fracture site was anterior mandible, and 155 cases involved a tooth-bearing area. Minor complications were seen in 8.03% of cases, whereas only 1.49% of patients suffered from major complications. The treatment of mandible fractures using 3D miniplates resulted in fracture reduction with a low complication rate.

Mobile location-based services (LBS) represent a promising opportunity for inner-city retailers and service providers to react to changes in customer behavior due to digitalization. To gain competitive advantages, mobile LBS must offer customers high value-in-use and help them reach their shopping goals during their inner-city visits. Shopping goals differ depending on shopping patterns; thus, these patterns may influence customers’ evaluation of mobile LBS during inner-city visits. Since value-in-use is not only a context-specific but also a temporally dynamic construct, customers’ user experience must also be considered. Therefore, this study investigates the influence of customers’ shopping patterns and current user experience on their evaluation of mobile LBS’ value-in-use during inner-city visits. Moreover, the impacts of the offers transmitted through mobile LBS on the value-in-use are examined. Using field test data, we empirically verify a conceptualization of mobile LBS and determine a comprehensive view of mobile LBS’ value-in-use during shopping trips with different shopping patterns and user experience within a mixed-method analysis. Our results identify both utilitarian and hedonic value-in-use components as being empirically relevant for high value-in-use evaluations regarding mobile LBS in inner cities. Furthermore, the relevance of monetary benefits, fun benefits, and irritation on value-in-use vary according to customers’ user experience. A customer’s shopping pattern affects the value-in-use of mobile LBS; however, this effect is not as differentiated as expected. Moreover, the number of relevant monetary and non-monetary offers transmitted during an inner-city visit are shown to represent a potential, albeit limited, management instrument for affecting mobile LBS’ value-in-use.
