Strain visualization of supporting tissues rehabilitated using two different types of removable partial dentures
Vizuelizacija deformacija u potpornim tkivima rehabilitovanim sa dva različita tipa parcijalnih skeletiranih proteza
Апстракт
Introduction/Objective Current biomechanical analyses can provide full view of the strain induced by loading of various replacements to be used for prosthetic rehabilitation. The aim of this study was to analyze strain distribution of supporting tissues beneath two different types of removable partial dentures, commonly indicated in the conventional rehabilitation of partially edentulous patients. Methods This in vitro study included two groups of experimental models composed of the mandibles (Kenedy Class 1) and two types of removable partial dentures. These models were exposed to occlusal loading and the digital image correlation method was used for strain visualization and strain measurement. Results The highest strain was measured beneath the removable partial dentures, on the surfaces of bone adjacent to distal abutments and in the anatomical structure called the retromolar area. Strain values in the experimental models with clasp removable partial dentures ranged 0-10%. Strain va...lues in the experimental models with attachment - removable partial dentures ranged 0-2.3%. Conclusion The findings showed that the attachment retaining removable partial dentures induced lower strain in the residual alveolar ridges. However, higher strain was detected in the marginal bone next to the abutment teeth.
Uvod/Cilj Savremene biomehaničke analize omogućavaju kompletnu vizuelizaciju deformacija od opterećivanja različitih zubnih nadoknada u protetskoj rehabilitaciji. Cilj ove studije je bio da analiza distribucije deformacija unutar potpornih tkiva ispod dva različita tipa najčešće korišćenih parcijalnih skeletiranih proteza. Metode In vitro studija je obuhvatila dve grupe eksperimentalnih modela donjih vilica (Kenedi 1 klasa krezubosti) i dva tipa parcijalnih skeletiranih proteza. Modeli su bili izloženi okluzalnim silama, a za prikaz i merenje deformacija je korišćena metoda digitalne korelacije slika. Rezultati Najveća deformacija je izmerena ispod parcijalnih proteza, na površinama kosti koja okružuje distalne zube nosače i u retromolarnoj regiji. Vrednosti deformacija u eksperimentalnim modelima sa protezama retiniranim livenim kukicama su bile 0-10%. Vrednosti deformacija u eksperimentalnim modelima sa protezama retiniranim atečmenima su bile 0-2,3%. Zaključak Parcijalne skeletirane... proteze sa atečmenima indukovale su manje deformacije rezidualnog alveolarnog grebena. Veće deformacije su uočene u marginalnoj kosti koja je u neposrednom kontaktu sa zubima nosačima.
