Multi-objective optimization of custom implant abutment design for enhanced bone remodeling in single-crown implants using 3D finite element analysis

Scientific Reports
The optimal configuration of a customized implant abutment is crucial for bone remodeling and is influenced by various design parameters. This study introduces an optimization process for designing two-piece zirconia dental implant abutments.

Influence of Different Multilayer Zirconia Materials on the In Vitro Load‐Bearing Capacity of Resin‐Bonded Fixed Partial Dentures in the Posterior Region

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Comparison of the load‐bearing capacity and failure pattern of posterior resin‐bonded fixed partial dentures (RBFPDs) differing in retainer design, zirconia material, and vertical nesting position. Materials and Methods RBFPDs replacing a maxillary first molar were fabricated with 2 retainer designs (inlay‐retained, IR; wing‐retained,

Soft Tissue Volume Augmentation at Single Implant Sites Applying Collagen Matrices or Connective Tissue Grafts: 10‐Year Follow‐Up of a Randomized Controlled Trial

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Aim To compare up to 10 years clinical, profilometric and patient‐reported outcomes of implant sites previously augmented using a volume‐stable collagen matrix (VCMX) or connective tissue graft (SCTG) in the aesthetic zone. Methods The original non‐inferiority randomized controlled trial (RCT) enrolled 20 patients who received soft tissue ...

How the Build Angle Affects the Marginal and Internal Fit of 3D Printed Definitive FPDs: An in Vitro Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Statement of Problem Printing parameters may influence the fit of additively manufactured dental restorations. However, the effect of small incremental build angles on the marginal and internal fit of stereolithography (SLA)‐printed definitive 3‐unit fixed partial dentures (FPDs) has not been sufficiently investigated.

Assessing Color Inconstancy of CAD/CAM Materials: Influence of CIE White LED Illuminants and Substrate Shade

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To assess how the CIE white LED illuminants and substrate shade impact the color inconstancy of high‐translucency CAD/CAM materials. Materials and Methods From the spectral reflectance factors of Lava Ultimate‐LU, Grandio blocks‐GB, VITA Enamic‐VE, and VITA Mark II‐M specimens (n = 3/material) measured on nine background shades (ND1 ...
