The need to correctly predict teeth permanence in the mouth has caused each dental specialty to find ways to achieve it. Below is a summary of dental and periodontal examinations for prosthodontics, as well as the benefits of orthodontic procedures performed on abutment teeth in order to preserve them, as well as the tactical weight of each abutment.
Introduction: The purpose of the research was to determine the marginal and internal fit of titanium alloy crowns using the Selective Laser Melting technique and CAD/CAM milling. The crowns were made in SLM, a marginal fit that was slightly better internal fit than those that were milled crowns was found, as well as a comparable marginal fit. The mean deviations for the sintering were [mm]: u22120. 039 and +0. 091 for tooth 15, u22120. 033 and +0. 091 for tooth 36, and for tooth 15, and u20130. 048 and +0. 110 for tooth 15 and u20130. 036 and +0. 096 for tooth 36, as well as the milling [mm]: u22120. 039 and +0. 107 for tooth 15 and u22120. 031 and +0. 107 Conclusion: Based on the findings and the experience with therapeutic procedures, it can be concluded that the fitting of titanium alloy crowns in SLM and milling meets the clinical requirements.
