Additive Wax-Up and Diagnostic Mockup As Driving Tools for Minimally Invasive Veneer Preparations

Abstract

This report describes the importance of and outlines steps for additive wax-up and diagnostic mockup for anterior teeth as diagnostic and driving tools for non-prep and minimally invasive veneer preparations. A 35-year-old male presented to the clinic with the chief complaint of spaces between his front teeth. Diagnostic additive wax-up provided the possibility of offering minimally invasive preparations, and the use of a diagnostic intraoral mockup fulfilled the patient's esthetic demands for treatment approval. Veneer preparations over the diagnostic mockup were provided as they are minimally invasive. Ceramic veneers were hand-crafted following the previous diagnostic wax-up, and restorations were bonded under rubber dam isolation. Overall, additive wax-up provides information needed to know if minimally invasive veneer preparations are possible, and the diagnostic mockup displays a physical, tentative outcome for the patient's evaluation before irreversible tooth preparations. These simple, but effective, techniques can drive the diagnosis and prognosis of minimally invasive veneer restorations.

Effect of incisal preparation design on the fracture strength of monolithic zirconia‐reinforced lithium silicate laminate veneers

“…40 However, anterior teeth are commonly treated with ceramic LV. 41,42 The restoration preparations followed the guidelines provided by Celtra Duo (Dentsply Sirona) for veneers: 1.5 mm incisal reduction, 0.4 mm incisal, and 0.6 middle third reduction, whereas for full-coverage crowns: 1.5 mm incisal reduction, 1.0 mm chamfer margin, and 1.5 mm middle third reduction. 43 According to the manufacturer, LV with ZLS can be fabricated with thicknesses from 1.0 to 1.5 mm.…”

“…The maxillary right central incisor was selected in this study because central incisors are the most noticeable teeth in the mouth and, therefore, can cause the most esthetic concerns addressed by clinicians 40 . However, anterior teeth are commonly treated with ceramic LV 41,42 . The restoration preparations followed the guidelines provided by Celtra Duo (Dentsply Sirona) for veneers: 1.5 mm incisal reduction, 0.4 mm incisal, and 0.6 middle third reduction, whereas for full‐coverage crowns: 1.5 mm incisal reduction, 1.0 mm chamfer margin, and 1.5 mm middle third reduction 43 .…”

Minimally Invasive Laminate Veneer Therapy for Maxillary Central Incisors

“…The diagnostic wax-up is the first step, which can be performed using the additive technique, creating the possibility of a diagnostic mock-up. However, this may not be possible in situations where the tooth is rotated or tilted or there are interproximal gaps between the teeth [ 17 ].…”

Impact of restoration thickness and tooth shade background on the translucency of zirconia laminate veneers: An in vitro comparative study

“…Ceramic LVs are often used to address issues, such as incisal wear, facial defects, fractures, tooth discoloration, and interdental spaces in a conservative manner, since they only require the reduction of 25–50 % of tooth structure compared to traditional full coverage restorations ( Edelhoff and Sorensen, 2002 , Villalobos-Tinoco et al, 2020 ). Conservative preparations for LV restorations have been well documented in the literature and enable the fabrication of thin, bondable restorations on enamel tooth structure ( Afrashtehfar, 2021 , Villalobos-Tinoco et al, 2022 ).…”
