Occlusal vertical dimension: treatment planning decisions and management considerations
The International Journal of Esthetic Dentistry
|May 8, 2019
Summary
Altering occlusal vertical dimension (OVD) is a complex dental procedure. Dentists can modify OVD within physiological limits to improve aesthetics and function, but must carefully consider its implications.
Area of Science:
- Dentistry
- Restorative Dentistry
- Dental Aesthetics
Background:
- Occlusal vertical dimension (OVD) modification is a controversial topic in restorative dentistry.
- Indications for OVD alteration include harmonizing dentofacial aesthetics, creating space for restorations, and improving occlusal relationships.
Purpose of the Study:
- To critically review the literature on occlusal vertical dimension (OVD) alterations.
- To provide clinical objectives and subjective parameters for guiding OVD modification procedures.
Main Methods:
- Literature review of relevant studies on occlusal vertical dimension (OVD).
- Analysis of clinical objectives and subjective parameters for OVD alterations.
Main Results:
- OVD is a dynamic dimension within a zone of physiological tolerance.
- Altering OVD requires respecting the envelope of function to avoid adverse biological, biomechanical, and functional implications.
- Reconstruction of maximal intercuspation and anterior tooth relationships is necessary after OVD changes.
Conclusions:
- Occlusal vertical dimension (OVD) can be altered within physiological limits.
- Careful consideration of clinical and subjective parameters is essential for successful OVD modification.
- Guidance for clinicians and laboratory technicians is provided for OVD alteration treatments.

Design Consideration
562
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.

Vertical Curve: Problem Solving
483
Vertical curves provide the transition between two roadway grades, ensuring safety, comfort, and functionality. Calculating elevations at specific stations along the curve involves several systematic steps based on the curve's geometry and provided design parameters.The vertical curve is defined by its length, grades, Point of Vertical Intersection (P.V.I.) location, and P.V.I. elevation. The stations of the Point of Vertical Curvature (P.V.C.), where the curve begins, and the Point of Vertical...

Support Reactions in Three Dimensions
1.6K
Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system from translating and rotating, ensuring the design can withstand external forces and perform its intended function efficiently and safely. Some of the supports providing support reactions in three dimensions are discussed below:
Ball and Socket Joint is one of the supports allowing free rotation about any axis. This freedom of rotation is...

Relative Velocity in One Dimension
9.8K
The understanding of the concept of reference frames is essential to discuss relative motion in one or more dimensions. When we say that an object has a certain velocity, we must state the velocity with respect to a given reference frame. In most examples, this reference frame has been Earth. For instance, if a statement reads that a person is sitting in a train moving at 10 m/s east, then it implies that the person on the train is moving relative to the surface of Earth at this velocity,...

Sampling Plans
911
Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Introduction to Vertical Curves
576
Vertical curves are parabolic transitions that connect different grades on highways and railroads, ensuring a smooth alignment between back and forward tangents. The back tangent represents the initial grade, while the forward tangent defines the subsequent grade. These curves can be symmetrical, with equal tangent lengths, or nonsymmetrical, with varying lengths. The key points defining a vertical curve include the Point of Vertical Intersection (P.V.I.), where the tangents meet; the Point of...
