“…21,22 A number of factors affect the strength of inlay-retained FPDs, one of which is the dimension of the preparation. [23][24][25] Recently, instruments based on oscillating principles have been introduced. 26 These instruments are coated with diamond on only one side, which helps to guide the instrument at the proximal areas, preventing accidental damage of the adjacent tooth as may occur with rotary instruments.…”

The objective of this in vitro study was to evaluate the effect of box dimensions on the initial and final failure strength of inlay-retained fiber-reinforced composite (FRC) FPDs.Material and methods. Twenty-one inlay-retained FPDs were prepared using FRC (everStick) frameworks with unidirectional fiber reinforcement between mandibular first premolars and first molars. Boxes were prepared using conventional inlay burs (Cerinlay), and small and large ultrasonic tips (SONICSYS approx). Box dimensions were measured after preparation with a digital micrometer. All restorations were subjected to thermal cycling (6000 cycles, 5°C-55°C). Fracture testing was performed in a universal testing machine (1 mm/ min). Acoustic emission signals were monitored during loading of the specimens. Initial and final fracture strength values (2-way ANOVA, Bonferroni post hoc tests, a=.05) and failure types (Fisher exact test) were statistically compared for each group.

“…On the basis of the contours of the solid model, periodontal ligaments (PDL) and alveolar bone (cortical and cancellous bone) volumes were created according to literature data. 16 To understand the interactions among the retainer design factors, the thickness (T), height (H) and angle of the axial surface extension (A) were selected as the design parameters. Three values of T (1.2, 0.8 and 0.4 mm), H (100, 75 and 50% of the distance from 2 mm above the CE junction to the occlusal surface), and A (150, 180 and 2108) were chosen (Fig.…”

“…The coordinates of each point on the contours were then input into an FE package (ANSYS, Swanson Analysis Inc., Houston, USA) to build solid models for the prosthesis and abutment teeth. Based on the solid model contours, periodontal ligaments (PDL), and alveolar bone (cortical and cancellous bone) volumes were created according to literature data [9].…”

This study determines the RBFPD (resin-bonded fixed partial dentures) biomechanical aspects to retainer height using structural-thermal coupled finite element (FE) analysis under normal (37°C) and high (51°C) oral temperatures. Three RBFPD FE models with different retainer heights (100, 75, and 50% of the distance from 2 mm above the CE (cementum-enamel) junction to the occlusal surface) were created using image processing, contour stacking, and mapping mesh procedures. After FE model validation, the maximum first principal and von Mises stresses in the remaining tooth (σ(T)) and prosthesis (σ(P)), were recorded for all models under structural-thermal coupled analyses. The simulation results showed that the σ(T) and σ(p) values decreased with greater retainer height as a result of the increasing prosthesis stiffness and maximizing bonding area between the enamel and retainer at normal oral temperature (37°C). However, no significant stress differences were found according to the retainer height varying dimensions at high (51°C) temperatures. The RBFPD retainer height biomechanical response is dominated by the structural analysis result (at 37°C) and it is recommended that the prosthesis retainer have as great a height as possible to decrease the stress values.
