Establishing a classification system and criteria for veneer preparations
Compendium of Continuing Education in Dentistry (Jamesburg, N.J. : 1995)
|April 6, 2013
Summary
A new classification system for dental veneers is proposed to categorize preparation levels, improving communication and treatment planning for dentists and patients. This system quantifies tooth structure removal, promoting conservative approaches.
Area of Science:
- Dentistry
- Restorative Dentistry
- Dental Materials
Background:
- The concept of no- or minimal-preparation veneers has existed for over 25 years.
- A lack of standardized classification for veneer preparation leads to misunderstandings.
- Clearer categorization is needed for effective patient and professional communication.
Purpose of the Study:
- To propose a novel classification system for dental veneer preparations.
- To address the need for standardized terminology in veneer treatment.
- To facilitate conservative treatment planning and enhance communication.
Main Methods:
- A classification system is proposed based on quantifiable metrics.
- Metrics include enamel reduction (space requirement, working thickness, material room).
- The system also considers the volume of remaining enamel and percentage of dentin exposed.
Main Results:
- The proposed system offers an accurate measurement for quantifying tooth structure removal.
- It allows for a case-by-case assessment of preparation extent.
- Facilitates a preferred approach of no or minimal tooth reduction.
Conclusions:
- A standardized classification system is crucial for veneer preparations.
- This system can reduce uncertainty in treatment planning and execution.
- It enhances communication among dental professionals and with patients regarding veneer treatments.

01:19Veneer
Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

01:21Wood Products
Wood products encompass a broad range of materials crafted from wood strands, veneers, lumber, and even waste wood-like shreds, designed for both structural and nonstructural purposes. Various specialized wood products have been developed to enhance strength, durability, and versatility in building applications.
Glue-laminated wood, often referred to as glulam, combines multiple smaller pieces of dimensional lumber using adhesives to form a single, larger piece. Cross-laminated timber consists...

01:14Wood Surfacing
Wood surfacing is a critical finishing process designed to smoothen the wood surface, enhance its dimensional accuracy, and make handling safer. This process compensates for potential shrinkage during the seasoning phase by marginally increasing the wood dimensions before surfacing. It also helps correct some distortions that may occur as the wood dries.
The equipment used in the surfacing process is a plane equipped with rotating blades. This tool efficiently smoothens the wood surface and can...

01:28Softwoods and Hardwoods
Softwoods and hardwoods, derived from different types of trees, are distinguished by their leaf structures and cellular compositions, each serving unique purposes in construction and manufacturing. Softwoods come from cone-bearing trees with needle-like leaves and are predominantly composed of longitudinal cells called tracheids and a smaller proportion of radial cells known as rays. Due to their cellular structure, softwoods are commonly used in construction for structural frames, sheathing,...
01:22Classification of Epithelial Tissues: Overview
Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
Based on the number of cell layers,...

01:03Fixation and Sectioning
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
