Abstract:
We examined 408 patients (151 male, 257 female) in an age range from 54 to 85 years (mean age 73,9±4,9) performing clinical (anamnesis, visual analysis, palpation, percussion, auscultation) sociological (GOHAI), additional (chewing efficiency evaluation, phonetic analysis, weight deficit of body calculation, OPG, CBCT) assessment. Among 322 of examined subjects working syndromological diagnosis was «decompensated dentition» related to lower jaw in 167 cases, 65 to upper jaw, 90 to both upper and lower jaws (altogether 412 dental arches). Chewing efficiency among edentulous patients was low considering that majority of patients had dentures. Score range for Geriartric General Oral Health Assessment Index (GOHAI) was from 7 to 25 points (mean 18,23±4,19) which is attributed as low level. General syndromes among patients were rough, disfiguring, ageing changes in facial appearance, major alteration of aesthetic norms. Equally important or even more was incapacitation impact of total loss of proper mastication, speech problems, phonetic alteration, problematic food swallowing. In our research we highlighted two pathological conditions among elderly and senile age groups: decompensated dentition, and fully edentulous jaws. Taking into consideration suffering of the patients due to morphological functional and psychosocial disabling conditions, accompanying these diseases, we might consider this group of patients as handicapped and that could lead to the need to introduction of setting quotas of implant prosthetics treatment of the elderly and senile patients. The result, efficacy and efficiency of such rehabilitation are considered in compliance with the system of adequate treatment result for this part of population.
