Can you please give me your advice on shade guides?

Vident has excellent products for shade selection. The 3D Master Shade Guide offers a systematic, logical method for shade taking that, if the instructions are followed correctly, make shade selection fairly simple. There are several versions of this guide, including a Linearguide 3D Master, which offers an even simpler shade selection method. Also, there is a bleach guide, for monitoring shade changes in bleaching patients.

Most ceramics can be keyed to the Vita shade system. However, the Vita ceramics are high quality, which make them a good choice for dental restorations.

Vident has an interesting new product for shade selection called the Vita Easyshade Compact, which is a hand-held color measuring device keyed to the Vita shade guides. If you have trouble with shade selection, this product could help you.
