The Spot‐Dam Technique: A Protocol for Adhesive Cementation of BOPT Crowns

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The Biologically Oriented Preparation Technique (BOPT) uses vertical tooth preparation without a defined finish line, guided by provisional restorations to shape the gingival emergence profile. Subgingival crown margins inherent to BOPT increase the risk of residual cement and soft‐tissue trauma during adhesive cementation.

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

Journal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

Peri‐implant tissue definition and registration with a 3D‐printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report

Journal of Prosthodontics, EarlyView.
Abstract Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri‐implant health, and ensure long‐term success. Traditionally, titanium stock healing abutments or chairside‐customized abutments were used to shape peri‐implant tissues and develop the emergence profile for implant‐supported prostheses.

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
