Composite veneers vs Porcelain veneers. Which is best?

One of the most topical subjects at the moment is the debate between composite and porcelain for dental restorations. In terms of cosmetic dentistry, this equates to the use of composite veneers and porcelain veneers. It is important to note that composite veneers can either be made by a laboratory or placed free hand by the dentist in the chair. Porcelain veneers can only be made by a dental laboratory or within a dental practice that has the necessary technology such as computer aided design and a milling machine, otherwise know as CAD-CAM.

The advantages and disadvantages of composite

The advantages of dental composite for veneers include:

1. In most cases, very little if any tooth preparation is needed

2. Repair is possible in the mouth should a veneer chip, fracture or exhibit staining

3. Less expensive than porcelain veneers

4. Alterations in shape are easy to make

5. Removal and maintenance is straight forward

6. A good level of aesthetics can be achieved

The disadvantages of composite include:

1. Being a resin, the material is less durable than porcelain and will degenerate over time

2. Will eventually stain

3. High quality characterisation is not possible i.e a matt finish is possible not a glossy one and aspects like translucency, light reflection, opacities, craze lines etc are not really comparable to porcelain.

4. Typically last for 5 years and maintenance will be needed in the interim period

The advantages and disadvantages of porcelain

The advantages of porcelain for veneers include:

1. Highly aesthetic with beautiful characterisation possible leading to life like properties

2. Far more durable than composite

3. Minimal tooth preparation is possible when teeth are straight

4. Do not stain

The disadvantages include:

1. In most cases, tooth preparation is necessary to ensure a sound seating and avoid a ledge

2. Repair is not possible in the mouth. A complete replacement is necessary if there is a crack or chip.

3. More expensive than composite veneers or bonding.

Case of the Month August 2024

Our case of the month for August is one that involves replacing composite veneers for porcelain due to discolouration over time and a desire for a greater level of aesthetics and long term durability. This case shows the disparity between the materials and just how life like porcelain can be.
