Summary
Centric relation (CR) lacks diagnostic support in dentistry and may be anatomically unsupported. However, CR can be pragmatically useful therapeutically in prosthodontics for maxillo-mandibular reference.
Area of Science:
- Dentistry
- Dental Occlusion
- Temporomandibular Disorders
Background:
- Centric relation (CR) is a highly debated concept in dentistry regarding its biological, diagnostic, and therapeutic utility.
- Existing debates question the validity and application of CR in clinical practice.
Purpose of the Study:
- To review current literature on the diagnostic and therapeutic applications of CR in dentistry.
- To assess the evidence supporting CR recording methods for temporomandibular disorders and prosthodontic/orthodontic treatments.
Main Methods:
- A comprehensive literature review was conducted.
- Included clinical trials assessing CR recording methods for diagnostic and therapeutic uses.
Main Results:
- No substantial literature supports the diagnostic use of CR for identifying temporomandibular joint condyle position.
- CR can be pragmatically useful in prosthodontics as a maxillo-mandibular reference when maximum intercuspation is compromised.
Conclusions:
- Diagnostic misuse of CR leads to circular reasoning in treatment goals.
- The term 'Centric Relation' may be better replaced with 'Maxillo-Mandibular Utility Position'.

02:25Centrosome Duplication
4.1K
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).

01:13Centrioles and Centrosomes
2.8K
Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.

02:30Histone Variants at the Centromere
4.4K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

01:16Eccentric Axial Loading in a Plane of Symmetry

Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

3.3K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.

01:12General Case of Eccentric Axial Loading
216
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
