Establishing a classification system and criteria for veneer preparations
ABSTRACT The concept of no- or minimal-preparation veneers is more than 25 years old, yet there is no classification system categorizing the extent of preparation for different veneer treatments. The lack of veneer preparation classifications creates misunderstanding and miscommunication with patients and within the dental profession. Such a system could be indicated in various clinical scenarios and would benefit dentists and patients, providing a guide for conservatively preparing and placing veneers. A classification system is proposed to divide preparation and veneering into reduction--referred to as space requirement, working thickness, or material room--volume of enamel remaining, and percentage of dentin exposed. Using this type of metric provides an accurate measurement system to quantify tooth structure removal, with preferably no reduction, on a case-by-case basis, dissolve uncertainty, and aid with multiple aspects of treatment planning and communication.

- "The color and integrity of dental tissue substrates to which veneers will be bonded are important for clinical success ; using additional veneers with a thickness between 0.3 mm and 0.5 mm, 95% to 100% of enamel volume remains after preparation and no dentin is exposed . A number of clinical studies have concluded that bonded laminate veneer restorations delivered good results over a period of 10 years and more   . "
ABSTRACT: No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients' restorative and esthetic needs. The case report presented describes minimal invasive treatment of four upper incisors with laminate nanohybrid resin composite veneers. A step-by-step protocol is proposed for diagnostic evaluation, mock-up fabrication and trial, teeth preparation and impression, and adhesive cementation. The resolution of initial esthetic issues, patient satisfaction, and nice integration of indirect restorations confirmed the success of this anterior dentition rehabilitation.06/2014; 2014(ID 849273):9 pages.

ABSTRACT: Very minimal preparation with enamel preservation offer best results in esthetic dentistry. Composite restoration offer repairable option for a smile treatment plan. Sometimes, it may be preferable to extend the veneer preparations beyond the contact points toward the palatal surface, to hide the margins of the restoration. The case report presented describes minimal invasive treatment of four upper incisors with laminate ceramic veneers. A step-by-step procedure is proposed for diagnostic evaluation, mock-up fabrication and trial, teeth preparation and impression, and adhesive cementation. Patients have the chance to evaluate the function, esthetics and phonetics before the permanent restoration.
