This work presents a three-dimensional FE frictional contact formulation with NURBS-enriched elements for the debonding of partially osseointegrated, cementless implants. The model is based on modified Coulomb's friction law [1] that can tangential osseointegrated Here, smooth transition function between two coefficients used to decrease due implant. applied simulate hip implant determine influ...

Abstract This study evaluated shear bond strength (SBS), adhesive remnant index (ARI) and fracture mode of chemically mechanically retained ceramic brackets bonded with different composite resins irradiated CO2 laser. The null hypothesis was that laser would have similar SBS values. Ninety human premolars were divided into four experimental groups according to the combination type resin (Transb...

Objectives: To conduct a systematic review assessing quantitative enamel loss occurring after orthodontic debonding and clean-up procedures. Materials Methods: A search following the Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) statement was performed on different databases (Embase, Medline, Scopus, Web of Science) papers investigating volumetric due to bracket clear ...

Aims: To verify the efficacy of Er,Cr:YSGG laser for debonding lithium disilicate (LD) reinforced glass ceramic veneers different thicknesses. Methods: Forty bovine teeth were prepared and randomly divided into four groups (n=10/group) according to disc thickness: C0.5 (Control group) L0.5 (Laser irradiated in which LD discs had a thickness 0.5mm 5mm diameter; C1 L1 1mm diameter. The disilcate ...
