Veneer

115
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...

Summary

This review found that computer-aided design-computer-aided machining (CAD-CAM) and conventional feldspathic porcelain laminate veneers (PLVs) show similar marginal adaptation. All ceramic veneer fabrication methods evaluated offer clinically acceptable marginal fidelity.

Area of Science:

  • Dental Materials Science
  • Prosthodontics
  • Biomaterials Engineering

Background:

  • Accurate marginal adaptation of dental veneers is crucial for long-term clinical success and preventing secondary caries.
  • Different fabrication techniques, including conventional feldspathic porcelain laminate veneers (PLVs), computer-aided design-computer-aided machining (CAD-CAM) veneers, and pressed veneers, exist for ceramic restorations.
  • Understanding the comparative marginal adaptation of these techniques is essential for clinicians selecting appropriate restorative materials.

Purpose of the Study:

  • To systematically review and evaluate the marginal adaptation of dental veneers fabricated using conventional feldspathic PLVs, CAD-CAM, and pressed techniques.
  • To compare the marginal fidelity of ceramic veneers produced by various manufacturing methods.
  • To determine if significant differences exist in the marginal adaptation between CAD-CAM and conventional feldspathic PLVs.

Main Methods:

  • A comprehensive literature search was conducted using PubMed and Google Scholar, supplemented by hand searches.
  • Studies were screened based on predefined inclusion and exclusion criteria related to veneers and marginal adaptation.
  • Data extraction and analysis were performed on the six included studies for assessing margin adaptation.

Main Results:

  • The systematic review included six studies after an initial search identified 130 articles.
  • No statistically significant differences were observed in the marginal adaptation between CAD-CAM veneers and conventional feldspathic PLVs.
  • The marginal fidelity of ceramic veneers across all evaluated fabrication techniques was found to be clinically acceptable.

Conclusions:

  • Conventional feldspathic PLVs and CAD-CAM fabricated veneers demonstrate comparable marginal adaptation.
  • The fabrication method does not appear to significantly impact the marginal fidelity of ceramic veneers.
  • All evaluated ceramic veneer fabrication techniques provide clinically acceptable marginal adaptation, ensuring reliable restorations.
