“…A conservative preparation with a minimum of tooth reduction, a potential for excellent esthetics and maintenance of healthy tissues are the major advantages of porcelain laminate veneers [15][16][17]. However, in such cases of marginal adaptation or periodontal response problems, microleakage, and cracks on the laminate veneers may indicate the replacement of these restorations [2].…”

Effects of different application durations of scanning laser method on debonding strength of laminate veneers

et al. 2011

Porcelain laminate veneers as esthetic and minimally invasive restorations are being used as an alternative to full veneer crowns. However, the removal of porcelain veneers that have failed may be an uncomfortable and time-consuming procedure because of the high bond strength between the porcelain laminate veneers and the tooth surface. The purpose of this study was to prepare a simple and reliable method for porcelain laminate veneer debonding by using an Er:YAG laser with the scanning method and to determine the amount of lasing time required. Eighty cylindrical specimens with a thickness of 0.7 mm and a diameter of 5 mm were fabricated from Empress II ceramic material. They were cemented on the labial surface of extracted bovine mandibular incisors using Variolink II (Ivoclar Vivadent AG, Schaan, Liechtenstein) and light cured for 40 s. The specimens were randomly divided into four groups of 20. The first group was assigned as the control group and no laser application was performed. The Er:YAG laser was applied on each specimen in the other three study groups for 3, 6, and 9 s by using the scanning method. One second after the lasing, a mechanical force was applied to remove the laminate veneers by using an Instron Universal Testing machine. Results of this study exhibited statistically significant differences between the control group and the three study groups. Intergroup comparison of shear bond strengths of the three study groups showed a statistically significant difference (p = 0.0001). This study showed that all three application times of Er-YAG laser were effective for debonding ceramic laminate veneers by softening the adhesive resin.

“…The patients were questioned about possible postoperative complaints [6,24]. Moreover, plaque index [25], gingival index [26], and increase in gingival recession were included as an evaluation of gingival response to the veneer [27]. The involved teeth were photographed preoperatively and postoperatively, as well as at recall appointments (Fig.…”

Clinical evaluation on porcelain laminate veneers bonded with light-cured composite: results up to 7 years

et al. 2011

The purpose of this study was to evaluate the clinical performance of laminate porcelain veneers bonded with a light-cured composite. Thirty patients were restored with 119 porcelain laminate veneers. The veneers were studied for an observation time of 7 years. Marginal adaptation, marginal discoloration, secondary caries, color match, and anatomic form were clinically examined following modified United States Public Health Service (USPHS) criteria. Each restoration was also examined for cracks, fractures, and debonding. Pulp vitality was verified. In addition, plaque and gingival indexes and increase in gingival recession were recorded. Survival rate evaluating absolute failures and success rate describing relative failures were statistically determined, using both restoration and patient-related analyses. On the basis of the criteria used, most of the veneers rated Alfa. After 7 years, the results of the clinical investigation regarding marginal adaptation and marginal discoloration revealed only 2.5% and 4.2% Bravo ratings, respectively, among the 119 initially placed veneers. Using the restoration as the statistical unit, the survival rate was 97.5%, with a high estimated success probability of 0.843 after 7 years. Using the patient as the statistical unit, the survival rate was 90.0% and the estimated success probability after 7 years was 0.824. Gingival response to the veneers was all in the satisfactory range. Porcelain laminate veneers offer a predictable and successful treatment modality giving a maximum preservation of sound tooth. The preparation, cementation, and finishing procedures adopted are considered key factors for the long-term success and aesthetical result of the veneer restorations.

“…Some authors 9,[12][13][14][15][16][17] have reported low rates of failure because of the loss of retention and fracture (0-5%) with short and mediumterm studies of up to 5 years. Indeed, a long-term follow-up 18 of veneers placed over a 10-year period shows a survival rate of 91% at 10.5 years (calculated with the Kaplan Meyer method).…”

Crowns and other extra-coronal restorations: Porcelain laminate veneers

2002

View full text Add to dashboard Cite

Porcelain veneers are resin-bonded to the underlying tooth and provide a conservative method of improving appearance or modifying contour, without resorting to a full coverage crown. The porcelain laminate veneer is now a frequently prescribed restoration for anterior teeth. The sums spent by the Dental Practice Board on this type of treatment increased from quarter of a million pounds in 1988/89 to over seven million in 1994/95, 1 representing some 113,582 treatments. Since that time the number has stabilised at over 100,000 veneers prescribed each year. 2 The objective of this paper is to give a practical guide on providing these restorations.
