ABSTRACT
This work dealt with clinical experience since 1992, in management by functional therapy of mandibular condyle fractures, of the Institute of Oral and Maxillo-Facial Surgery in the I Policlinico of Naples. In this work from 87 treated patients, only a group of 8 has been considered because it expresses the heterogeneity of all cases about the age, the sex, the kind and the level of fracture and the association with other fracture of the skull. The results obtained show that the functional therapy must be considered the first opinion in the mandibular condylar fractures at least there are specific conditions.

In this study the following commercial products were thermo-analysed (TG, DTG, DTA): reabsorbable Dac Blu, non reabsorbable Dac Blu, non reabsorbable atomized Dac Blu, non reabsorbable thin Dac Blu, reabsorbable Biocoral 450, non reabsorbable thin Dac Blu, reabsorbable Biocoral 450, Calcitite 2040-12, Orthogel, Apagen, BTF 65, Calcitite 4060-2, Osprogel, Bio-Oss, Biostite, Osprovit, Merck Hydroxiapatite. The apparatus utilized was a Setaram TAG 24, in a symmetrical set up, which gave the TG, DTG and DTA analysis simultaneously. The analysis of all the materials were performed in correct operative conditions. The thermo analyses gave useful information about the thermal stability of the samples. The TG analysis gave the data relative to the percentage of weight loss due to the volatile substances in the samples (H2Oass C, OH-, CO2). The DTG graph made it possible to establish the presence of carbonate apatite and/or hydroxyapatite or the absence of both the substances. Finally, DTA and DTG analyses allowed show the presence of various organic substances. These data were very useful to characterize the examined materials and confirmed the extreme importance and sensibility of this method.
