title: [Incidence and causes for fracture of removable plaque prostheses].
abstract: The great number of subjects in the former Mihajlovgrad district, asking for repair of removable dentures, provided grounds the author to study clinically that problem. A total of 324 subjects, aged from 16 to 90, with 320 prostheses were inquired according to various indices. Interstings facts and regularities were established necessitating an original prophylactic activity for reduction of the number of breakings and prolongation the functional fitness of the plaque partial prosthesis, in mass use in the practice. The upper prostheses are broken three times more often than the lower ones. The partial prostheses are broken 1.7 times more than the total. Almost half of all broken prostheses (47.38%) are upper partial. The most frequent defect is a broken prosthesis with complete separation of the fragments (56.20%). The cracked prostheses are 21%. Two thirds of all prostheses received (65%) are repaired more than once and 1/3 of all prostheses are repaired 3 and more than 3 times. Treatment with practically healed prostheitic field has been performed in only 20 per cent of the subjects. The author proposes a simultaneous laboratory lining in cases of broken old prostheses and the existence of great changes in the prosthetic field. Close attention is recommended in the clinical design and laboratory making of the upper partial prosthesis.
