Veneers: Materials, Applications, Advantages and TechniqueS



A veneer may be a thin sheet of fabric placed on the front surface of the tooth, used for aesthetic purposes and protection. It’s usually a skinny layer of restorative material replacing the enamel. When multiple thin layers of wafer thin shells are chemically bonded to the tooth structure it’s called laminate veneer. “lamination” is the process which refers to joining the materials together. The difference between a veneer and laminate is that a veneer may be a layer material placed over the tooth to vary the color of the tooth as they’re tooth colored restorations. Dental veneers are thin, custom-made shells that dentists can place on the front of the teeth to enhance their appearance. Veneers can hide stained, chipped, and uneven teeth. For some people, having damaged or discolored teeth can affect their confidence or self-esteem. Dental veneers can help improve the looks of the teeth. Dental veneers are thin, custom-made shells that dentists can place on the front of the teeth to enhance their appearance.


  • localised defects
  • generalised defects
  • intrinsic discolouration
  • diastema
  • Chipped tooth
  • worn dentition
  • malaligned teeth
  • excessively discoloued teeth
  • peg laterals


They are extensively used as they’re biocompatible, strong, durable, stain resistant, show longevity, little recovery time, good clinical performance and are minimally invasive compared to crowns. In recent years there have been various advancements in dental implants and veneers with the aim of overcoming the previous shortcomings and for a more conservative feasible approach. The varied recent advancements in dental implants and veneers are discussed during this review .

Over the years there are various advancements in laminates and veneers in dentistry. The recent advancements are:

  • stacked/feldspathic teeth veneers
  • thick monochromatic teeth veneers
  • teeth veneers with reinforced leucite
  • lithium disilicate teeth veneers
  • ->lumineers
  • ->Durathin veneers
  • ->vivaneers
  • Leonardo veneers
  • MAC veneers
  • zirconia veneers

Stacked/feldspathic teeth veneers:

These veneers contain many stacks of porcelain giving rise to multiple layers within the veneer. The feldspars contain fluorapatite crystals improving the optical appearance of the tooth. It has a polychromatic appearance and high translucency, hence closely resembles the natural tooth. Hence it’s of great esthetic value. It is the very best quality cosmetic veneers. They are not as thick as monochromatic veneers.

Teeth veneers with reinforced leucite:

They are thinner veneers, having good aesthetics and used when teeth require minimal preparation. These veneers are patented and are available only from a lab in California and aren’t widely available. Reinforced Leucite features a flexural strength of 120-140 MPa and a moderate compressive strength.

Thick monochromatic teeth veneers :

These are usually thicker than the traditional veneers, hence contributing to its strength and sturdiness . they’re present in one color and may be customized consistent with the patient’s preference. they’re used when the teeth have got to be lengthened thanks to age or other factors. However these monochromatic veneers require more preparation to implement.

Lithium disilicate veneers :

They are the foremost widely used true glass ceramics. It’s versatile and is stronger than other porcelain veneers . it’s a high flexural strength and is out there during a sort of shade. it’s high resistance to thermal shock thus managing the matter between two similar materials. It’s used for teeth which need minimal reshaping.

Minimally invasive veneers or no prep veneers :

These veneers are ultrathin having a thickness almost like contact lenses of about 0.3-0.5 mm and hence get are called “contact lenses of teeth”. These help in greatly conserving the tooth structure as previously used porcelain veneers needed a compulsory 0.5mm to 1 mm removal of tooth structure in order that the skinny layer of porcelain.

Influence of preparation design on the survival of dental veneers

Different opinions are reported about superior preparation design over the others. In fact, thanks to the good variety within the materials, preparations designs and luting cement, favourable approaches to revive teeth with veneers are controversial.

This review aims to match the survival rate of dental veneers consistent with different preparation designs and different material types. The sub-aim is to succeed in a favourable preparation design and material supported scientific evidence.

One important aspect to research is the tooth preparation of dental veneers and the way it’d affect the fracture resistance of the fabric and reinforcement of the abutment tooth. Unfortunately, clinical trials that investigate the survival rate of dental veneers consistent with preparation designs are few, the standards of investigation would come with quite one factor which may affect the result of the treatment. In contrast, many in vitro studies are conducted to gauge the influence of various preparation designs. Although such studies don’t mimic the particular clinical environments and factors, they will provide criteria and guidelines for the clinician and further clinical investigations. illustrates the results of multiple in vitro studies regarding the influence of preparation design.

General concepts

Some features of the preparation design are highly recommended within the majority of the literature and lab studies. For instance , restricting the preparation to enamel is taken into account to be a critical factor for a favourable bonding strength, thus a more durable outcome. Additionally, preserving the interproximal contact is suggested in most of the literature and studies, this is often thanks to preserving more enamel and tooth structure, allowing a positive seat for cementation during a conservative approach. However, the clinician might face certain situations where removing the interproximal contact can provide better aesthetic results like malaligned teeth or diastema. Moreover, the quantity of labial reduction concurrent at 0.4-0.7 mm for ceramic veneers. This is often thanks to the enamel thickness within the anterior teeth, the enamel thickness of 114 extracted anterior teeth was 1.0 to 2.1 mm at the incisal third, 0.6 to 1.0 mm at the center third and 0.3 to 0.5 at the gingival third, therefore, minimal preparation is advisable.


Veneers may be a minimally invasive option for the treatment of discolored and malformed teeth. The recent advancements in veneers and laminates in dentistry have given rise to a superb alternative for a conservative approach for the teeth. It closely resembles the natural teeth and hence has good aesthetics.
