Use of alveolar distraction osteogenesis for anterior maxillary defect reconstruction.

Alveolar osteogenic distraction (AOD) is a biological process through which new bone formation occurs between bone segments that are gradually separated by incremental traction. This case report described the oral rehabilitation with dental implants of a patient with a vertical bone defect in the maxillary anterior region using the AOD technique. The patient presented with absence of the teeth 22, 21, 11, and 12 associated with a vertical bone defect.

Method triangulation to assess different aspects of food safety culture in food service operations.

The advantages and added value of applying method triangulation to gain a more comprehensive evaluation of the prevailing food safety culture in catering establishments is illustrated by means of a case study. Three methods are applied assessing the food safety culture in food service operations of a Flemish University spread over different locations in the city of Ghent, but centrally managed. Each method sheds light on one of the aspects of 'food safety culture' as defined in the food safety culture conceptual model, in which food safety culture is considered as the interplay between a techno-managerial route/aspect and a human route/aspect.

Ensuring food safety in food donations: Case study of the Belgian donation/acceptation chain.

The food donation process in Belgium is mapped and analyzed to identify bottlenecks in compliance with the legal framework and implementation of food safety management, based on literature search and interviews with stakeholders (donors, acceptors, regulators and facilitators) in Belgium and at EU level. The study revealed that the food donation/acceptation chain is far less structured and organized than the conventional food supply chain. The fragmented landscape of many small food banks and charity organizations (acceptors), often directed by and working with volunteers without training in food safety and lack of knowledge of legal food hygiene requirements is a bottleneck to generate trust among food donors and restricts the provision of perishable products in food donations.
