Methods: The physical and technical conditions of plaster models were sent by the dentists to 4 dental laboratories. All models were examined, photographed and recorded on a form according to the research objective. Results: A total number of 235 models sent by dental surgeons were used to prepare the metallic structure, in which none of the models presented surveying nor the path of insertion. Out of the 235 models, 41 (17.44%) presented serious failures, such as positive and negative bubbles, broken dental elements, direct retainers and damaged edentulous areas. With respect to the planning, only 22 (9.35%) models were presented with the metallic framework planning, but in an unsatisfactory way. Regarding mouth preparation, no model presented a guide plane, and only 6.8% of models had rests seats, but incorrectly prepared. Conclusion: The models evaluated presented poor quality, lack of planning and no mouth preparation. This shows the need for dental surgeons to be aware of the appropriate prosthesis models and plannings in order to ensure a satisfactory and long-term rehabilitation of the patient, as well as preserving the remaining mouth structures.

RESUMO Objetivo: Avaliar os modelos e planejamentos das estruturas metálicas das próteses parciais removíveis enviadas aos laboratórios de prótese dentária da cidade do Recife. Métodos: Foram avaliadas as condições físicas e técnicas dos modelos de gesso enviados pelos dentistas à 4 laboratórios de prótese dentária. Todos os modelos foram examinados, fotografados e registrados por meio de um formulário de acordo com o objetivo da pesquisa. Avaliou-se 235 modelos enviados pelos cirurgiões dentistas para confecção
