Article Synopsis
- The study focuses on the difficulties of designing prosthetic occlusal surfaces that accurately reflect a patient's jaw movements, highlighting the need for precision in avoiding occlusal interferences during lateral excursions.
- It aimed to evaluate the effectiveness of digitally replicating mandibular movements to identify and correct these interferences in CAD-CAM zirconia crowns through two different adjustment methods.
- Results showed that crowns adjusted using only buccal records (Group I) had higher lateral pressure measurements compared to those adjusted with both buccal and lateral records (Group II), suggesting that the latter may lead to better occlusion outcomes.
Background: Recently, prosthodontic approaches involve more conservative procedures that include less invasive finish line preparations that use less ceramic thickness.
Aim Of The Study: This in vitro study aimed to evaluate the effect of vertical preparation and modified vertical preparation designs on the marginal adaptation and fracture resistance of two types of ceramic crowns using CAD/CAM technology.
Materials And Methods: Two typodont maxillary first premolars were embedded in acrylic resin.
Background: Interim crowns are utilized for restoring implants during and after the process of osseointegration. However, studies on adaptation and fracture strength of implant-supported interim crowns are rare.
Aim Of The Study: The aim of this in vitro study is evaluating marginal fit and fracture resistance of conventional, subtractive, and additive methods of fabricating implant-supported interim crowns.
Background: The rising demand for improved aesthetics has driven the utilization of recently introduced aesthetic materials for creating custom post and core restorations. However, information regarding the fracture resistance of these materials remains unclear, which limits their practical use as custom post and core restorations in clinical applications. AIM OF THE STUDY: This study aimed to evaluate the fracture resistance of three non-metallic esthetic post and core restorations and their modes of failure.

The purpose of the study was to compare the bond strength and marginal adaptation of nano-ceramic hybrid composite crowns cemented to stock cement-retained abutments to lithium disilicate crowns.
Methods: Twenty abutment analogs were embedded into auto-polymerizing acrylic resin blocks.
Statement Of Problem: Whether reusing the buttons of pressable ceramic materials affects their color or translucency is unclear.
Purpose: The purpose of this in vitro study was to investigate the effect of additional pressing on the color and translucency of 3 different lithium disilicate ceramic brands.
Material And Methods: Seventy-two disk-shaped ceramic specimens (Ø14×1.
