According to classification of Misch et al. [3 (link)], nonfunctional immediate restoration loading protocol was done. After 48 h, the occlusion was evaluated to confirm the presence of sufficient inter-occlusal space. An impression was taking using addition silicon material (Ormaplus Cap. Soc. Euro R.E.A. 829391 C.C.I.A.A. Torino). Within 48 h, a provisional crown restoration (Protemp, 3M ESPE AG, Germany) was fabricated and cemented using eugenol-free provisional luting cement. The excess cement was carefully removed and care was taken to ensure that the margin of the provisional crown did not impinge on or irritate the soft tissue.

The temporary veneers were obtained with the temporary resin (Protemp, 3MESPE, USA) using previously fabricated silicon index I. Provisional veneers remained seated on the teeth thanks to material retention in the interproximal areas; part of the material was left in this area for adequate maintenance until the next visit. Any excess of the material around the gingival papilla was meticulously removed using scalpel no.12 or an Excesso instrument (LM Dental, Turku, Finland). The remaining excess was gently removed with a bur no. 889540009 to avoid bleeding.

Ceramic Shade Selection and Temporary Prosthesis

Based on a shade guide (Vita, Classic, Germany), the suitable ceramic shade was selected. A putty and light body additional silicon impression was taken for the prepared pulp chamber and occlusal butt joint finish line. An alginate impression was taken for the opposing arch, then a squash bite with pink wax was sent to the laboratory. An interim prosthesis with self-curing resin (Protemp 3M, United States) temporized the prepared tooth and was cemented with eugenol-free temporary cement (Ora temp, United States).

This study was designed to characterize and compare four commercial bis-acryl composite resins: (1) Luxatemp (DMG), (2) Protemp (3M ESPE), (3) Structur Premium (VOCO), and (4) Telio (Ivoclar Vivadent) using SEM, Infra-red and mechanical analysis. Paste and catalyst pastes of each bis-acryl composite resin were mixed with dispensing guns and automix syringes and placed into molds according to norm 27 ANSI/ADA No. 27. All samples used for the assay previously rinsed with 70% ethanol and stored in double distilled water by 14 days at 37 °C.

Porcelain Veneer Preparation and Temporary Restoration

All restorations were changed to new ones according to indications. In all cases, the color was evaluated by both the dental technician and clinician before starting the porcelain veneer preparation. Additionally, photographs of the tooth before and after preparation were obtained.
The shape of the new porcelain veneers was tested by the mock-up procedure. Transferring the shape of the tooth from the wax-up was performed by means of a silicone index I (Zeta Plus L, Zhermack, Badia Polesine, Italy). The silicone excess was cut away with a surgical scalpel or a straight handpiece carbide bur, and then a composite temporization material (Protemp, 3M ESPE, St. Paul, MN, USA) was applied to the index and was introduced on the teeth. After the composite resin had fully set (about 5 min), the silicone index was gently removed and the excess material on the palatal side and the proximal surfaces was discarded.
Additionally, the silicon index II (Zeta Labor, Zhermack, Italy) was performed based on the diagnostic wax-up and cut with a scalpel no 10 (Swann Morton, Sheffield, England) into two parts in order to control the tooth reduction.

Extracted caries-free human molars (n = 40) were collected with informed written consent (REC Ref 12/LO/1836) and sterilized in 1% sodium hypochlorite (Milton's solution, Proctor & Gamble, USA).
Buccal enamel surfaces were sectioned using a water-cooled diamond wafering blade (XL 12205, Benetec Ltd., London, UK) and mounted in bis-acrylic composite (Protemp™, 3M, USA), leaving the natural curved buccal surface exposed. Samples were brushed using a manual toothbrush and placed in an ultrasonic bath (GP-70; Nusonics, Lakewood, US) for 15 minutes before finally being wiped with ethanol to remove the smear layer and debris.

The patients were treated between September 2009 and January 2010. The abutment teeth were prepared according to the guidelines for all-ceramic FDPs. After completion of the preparation the vital abutment teeth were treated with a dentine adhesive system (Syntac Classic, Ivoclar Vivadent AG, Schaan, Liechtenstein) to seal the dentinal tubules. Impressions were taken with an A-silicone impression material (President, Coltène Whaledent, Altstätten, Switzerland/Honigum, DMG, Hamburg, Germany) performing double-mix technique. The impression of the opposite jaw was taken with alginate. Provisional restorations were fabricated chair-side using a composite material (ProTemp, 3M ESPE, Seefeld, Germany) and cemented with an eugenol-free temporary cement (Freegenol).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
