Abstract:
Introduction. The evaluation of the factors that determine the stability of the cast denture în the terminal
unilateral partial edentations of maxilla and the optimization of the use of means of stabilisation with direct
and indirect action.
Aim of study. The aim of the planification of a cast denture is to ensure the mechanisms of stabilisation in
the base of the particularities of the partial edentulous prosthetic field and the morpho-pathophysiology of
the dento-maxillary apparatus.
Methods and materials. A database was created on the support of observation files of 7 (4 m., 3 f.) patients,
aged between 52 and 71 years with terminal unilateral partial edentations of maxilla, without essential
clinical signs of parodontal disease. All patients were examined by clinical instrumentation and paraclinical
methods and treated with partial cast dentures.
Results. The results of clinical instrumentation and paraclinical examination of all the patients from the
study lot ascertain the presence of an unilateral terminal dental breach of the maxilla. On those, in 2
situations has been constatated the loss of 3 consecutive teeth, in 3 situations – the loss of 4 teeth and in 2
situations – the loss of 5 consecutive teeth. In 4 clinical situations was found the presence of dental breach
on the opposite hemiarcade, in 2 situations, on the opposite hemiarcade where found teeth with different
coronal lesions, in one situation, on the opposite hemiarcade was not found any morphological changes.
The results of the clinical examination at the time of the probe of the future prosthetic construction in the
oral cavity, immediately after the treatment and after 2-3 months after the application of the prosthesis in
the oral cavity have proven that rigorously respecting the clinical and technical algorithm of planning the
construction of a cast denture in II class Kennedy edentulous patients on maxilla ensured the fixation and
stabilisation of the dental prosthesis on the prosthetic field.
Conclusion. The displacements of the terminal unilateral partial cast dentures on maxilla are complex.
Electing and emplacing the elements of support and stabilisation with direct and indirect need an evaluation
of the particularities of the dental field and the biomechanics of the future prosthesis.
