Comparison of the midline stress fields in maxillary and mandibular complete dentures: A pilot study

Study to evaluate the Effect of Silane Treatment and Three Different Woven Fiber Reinforcement on Mechanical Properties of a Denture Base Resin

“…7 Some of the factors responsible for denture fracture include stress intensification, increased ridge resorption leading to an unsupported denture base, deep incisal notching at the labial frena, sharp changes at the contours of the denture base, deep scratches, and induced processing stresses. 8,9 Various types of fibers including carbon fiber, aramid fiber, polyethylene fiber, and glass fiber have been used as reinforcements. Fibers can be used in three forms, namely, continuous parallel, chopped, and woven.…”

The stress state of the fraenal notch region in complete upper dentures

“…Eight identical CUDs were constructed according to a previously applied methodology which is briefly described in the followings [15][16][17]24].…”

“…Another important issue not addressed by these studies, concerns the direction of the stresses and whether it is constant or varies. Three recent studies using rosette strain gauges under simulated mastication conditions (alternated load), showed that the complexity of applied loads during normal functioning both in terms of their magnitude and direction, in combination with alterations in the directions and magnitudes of the principal stresses in the posterior field of the palatal segment induces a complex multiaxial stress state in the palatal segment of CUDs, leading to multiaxial fatigue [15][16][17].…”

Effect of Cantileverd Bar Length on Strain Around Two and Four-Implants Supporting A Mandibular Over-Denture

“…Increased tensile strain values at the bone/implant interface arenot desired, since they may cause bone loss through the induction of bone microdamage [40][41][42]. In contrast, in vivo studies showed a minimal influence of distal bar cantilevers on strains around 2 implants supporting mandibular overdentures [30].…”
