INTRODUCTION

Materials like zirconia oxide block and lithium disilicate block are very popular in the modern dentistry era of CAD/ CAM restorations. The market is flooded with lab scanners and milling machines which have become a standard of industrialisation and mass production for quicker treatment times.

Lithium disilicate and feldspathic ceramics restoration are widely used in Europe for minimal invasive and long-term treatments. They are also bonded friendly materials which are good for the tooth structure for long-lasting bonding and less aggressive preparation.

The materials used mostly in my daily work are the Creation LS press and Creation LS veneering materials for lithium disilicate, which is a continuation of the high-end Creation Willi Geller ceramic system known and tested over 35 years for it exceptional aesthetics and stable results for any types of materials used such as metal frame and zirconia oxide.

However, I am still partial towards handmade fabrication, customisable workflows, working with old traditional pressable or feldspathic techniques, and fully handmade on plaster or digitally printed models. Such techniques have proven to deliver highly aesthetic results and biocompatibility.

CASE ONE: FELDSPATHIC MINIMAL NONINVASIVE PREP

A young female patient was referred from a previous client. Her main complaint was about teeth 11 and 21, which kept falling due to some composites on the incisal edges. She had also undergone some orthodontic treatment which did not work out for her. The patient desired to close the diastema between the maxillary centrals and laterals incisors. After the consultation, it was decided to use noninvasive porcelain laminate veneers to help the patient fill the spaces (Figs. 1-10).

CASE TWO: THE ULTRACONSERVATIVE APPROACH

The patient presented with lost tooth structure due to the fall of the composite filling. In such cases, porcelain veneers may be used to provide additional volume. The approach is mostly non-preparation and ultraconservative. The bonding is the same procedure with a heated composite resin.

The use of porcelain veneers feldspathic or lithium disilicate with or without tooth preparation is an excellent technique when preservation of the existing tooth structure is a primary requirement. This conservative noninvasive and ultraconservative approach provides good aesthetics and acceptable long-term results while also meeting patient demands for noninvasive treatment and beautiful results (Figs. 11-19).
