This study is aimed to assess the functional results of cases with lower extremity malignant and metastatic bone tumours that were treated with modular tumour resection prostheses. ⋯ Although endoprosthesis reconstruction had advantages of giving very good functional results in the early phases, it was found to cause mechanical complications, especially in patients with primary bone tumours during the mid and late phases.

The aim of this study was to evaluate the accuracy of digital models produced with the three-dimensional dental scanner, and to test the dimensional stability of alginate impressions for durations of immediately (T0), 1 day (T1), and 2 days (T2). ⋯ This study showed that measurements on negative digital models offer a high degree of validity when compared to measurements on positive digital models and plaster models; differences between the techniques are clinically acceptable. Direct scanning of the impressions is practicable method for orthodontists.
