For this purpose, thermogravimetric analysis, including dynamic and isothermal tests, was performed for different formulations based on polylactic acid used in dental applications (scaffolds). In this work, lifetime is defined as the time passed for losing the 5 wt% of the mass corresponding to the first and main degradation process. The 5 mass% mass loss could be a critic parameter in manufacturing processes, in terms of economical profit and quality of the final product. The proposed model provides lifetime estimates of polymeric materials depending on the storage temperature. The present procedure permits to obtain lifetime estimates of materials characterized by more than one main degradation process, since they can be dis-overlapped using generalized logistic functions.engLifetimeScaffoldsThermogravimetricAnalysisLogistic FunctionKineticsBiopolymersjournal articleopen access10.1007/s10973-015-5083-1
