Monolithic hybrid abutment crowns: Influence of crown height, crown morphology and material on the implant-abutment complex.

Purpose: This in vitro study investigated the influence of material selection, crown morphology, and vertical crown height on the biomechanical behavior of screw-retained monolithic hybrid abutment crowns (HACs).

Methods: Ninety implants were embedded in accordance with ISO standard 14801; ninety HACs were mounted (N=90). Monolithic crowns with varying group-specific designs were luted using titanium bases.

Correlation between theoretical knowledge and the difference between self- and teaching doctor-assessment.

Objectives: The right intuition for self-assessment without overestimating or underestimating oneself compared to theoretical knowledge is a skill that requires conscious practice and is very often paradoxically opposed to the level of knowledge. Self-assessment is an essential skill for dental professionals for lifelong learning and improvement. The objective of our study was to assess the correlation between theoretical knowledge and the difference between self- and teaching doctor-assessment.

IN VITRO SURVIVAL AND FRACTURE FORCE OF LITHIUM DISILICATE HYBRID ABUTMENT CROWNS.

Purpose: To evaluate the behavior of hybrid abutment crowns fabricated from monolithic lithium disilicate ceramic (LDC) and to compare the influence of different in vitro artificial aging protocols.

Materials And Methods: A total of 32 monolithic hybrid abutment crowns of monolithic LDC were fabricated. Of these, 24 were artificially aged using three different protocols up to a 20 year simulation (1.

Assessment of a virtual prosthetic case planning environment for dental education - A multicentric analysis.

Objectives: The aim of the present study was the multicentric assessment of the virtual prosthetic case planning environment (VCPE), which relocates patient planning into the virtual space in dental education.

Materials And Methods: The VCPE is separated into two rooms: a virtual entry area where the user can choose between 10 different prosthetic case plans of ascending complexity, and a virtual patient case planning room. In spring term 2022, the use of virtual case planning was voluntarily assessed in four different German dental schools (DSs) from the perspective of both lecturers and students.

Biomechanical behavior of implants with different diameters in relation to simulated bone loss- an in vitro study.

Objectives: Bone resorption around implants could influence the resistance of the implant abutment complex (IAC). The present in vitro study aimed to assess the stability to static fatigue of implants presenting different levels of bone losses and diameters.

Materials And Methods: Ninety implants with an internal conical connection with 3 different implant diameters (3.
