Effects of porcelain layer thickness and luting resin cement on the opalescence properties of porcelain veneers

BackgroundWhen discolored teeth are repaired with porcelain veneers, the thickness of the restorations should be increased appropriately using opaque porcelain and bonded by applying opaque luting resin cement to cover discolored substrates. However, its impact on the opalescent performance has not been reported yet.PurposeTo analyze the effects of opacity, body porcelain layer thickness, and luting resin cement on the opalescence properties of porcelain veneer restorations for discolored teeth.MethodsNinety IPS d. SIGN A3 porcelain veneer specimens were prepared via powder–paste coating and sintering. Specimens were divided into three groups according to ceramic type and cement used or not: body porcelain group as control, body/opaque porcelain group and body/opaque porcelain–resin cement composite group. Each group was subdivided into three subgroups based on the thickness, 0.50, 0.75, and 1.00 mm (n = 10). Variolink N Bleach XL luting resin cement with thickness of 0.1 mm was applied to the bottoms of body/opaque porcelain specimens to produce body/opaque porcelain–resin cement composites. The opalescence (OP) values were calculated and the micromorphological characteristics were analyzed by scanning electron microscope (SEM). Statistical analysis was performed by using ANOVA test (P < 0.05).ResultsThe opalescence values determined for the body porcelain groups with thicknesses of 0.50, 0.75, and 1.00 mm and body/opaque porcelain specimens with thicknesses of 0.45/0.05, 0.70/0.05, and 0.95/0.05 mm were 3.35 ± 0.15, 3.83 ± 0.10, 6.73 ± 0.25, 7.95 ± 0.34, 15.16 ± 0.60, and 16.49 ± 0.89, respectively. The specimens in the body and body/opaque porcelain groups exhibited significant increases in their opalescence values with increasing thickness (P = 0.00). The opalescence values of the specimens increased significantly with the addition of a 0.05 mm opaque porcelain layer (P = 0.00). The opalescence values of the composites containing body/opaque porcelain layers with thicknesses of 0.45/0.05, 0.70/0.05, and 0.95/0.05 mm and luting resin cement were 9.46 ± 0.17, 16.47 ± 0.15, and 18.38 ± 0.47, respectively. The opalescence values of the composite specimens increased significantly with an increase in the thickness of the porcelain layer(P = 0.00).ConclusionsThe opaque porcelain layer and opaque resin cement can significantly improve the opalescence properties of porcelain laminate veneers for discolored teeth, but the opalescence performance is still poor than natural teeth. The body porcelain only contributes to opalescence within a certain thickness range.

Computer-Assisted Porcelain Laminate Veneer Preparation: A Scoping Review of Stereolithographic Template Design and Fabrication Workflows.

Computer-assisted preparation of porcelain laminate veneers (PLVs) using stereolithographic templates has been developed to enhance the accuracy of tooth preparation. However, the digital workflows involved in guided PLV preparation remain inconsistently defined across various practices. Therefore, this scoping review aimed to examine publications on computer-assisted PLV preparation to identify the key stage of digital workflows involved in designing and fabricating stereolithographic templates, as well as to highlight the limitations of various template designs. This scoping review aimed to identify publications on digital workflows for designing and fabricating stereolithographic templates in computer-assisted porcelain laminate veneer preparation. A systematic search on MEDLINE/PubMed, Web of Science and Scopus identified English-language articles published from 2014 to March 2024. Eligible articles focused on digitally designed and fabricated tooth reduction templates for porcelain laminate veneers, excluding conventional tooth preparation procedures for tooth reduction assessment. Seven clinical reports were included, demonstrating various 3D data acquisition techniques for virtual patient generation. All articles described virtual diagnostic wax-ups on digital casts, with two using a virtual articulator. Only five articles documented chair-side mock-ups with resin trial restorations to evaluate planned dental esthetics. Additionally, virtual tooth preparation prior to templates design was included in only four articles. The templates were designed using different software and ranged from simple designs with access windows to complex stacked templates with rotary instrument sleeved windows. Each template design had limitations affecting tooth reduction accuracy. All articles reported printing templates in clear acrylic resin using different technologies. In conclusion, the review highlights a lack of standardization in the digital workflow for designing stereolithographic templates for PLVs. Establishing a sound protocol for designing the tooth reduction templates is essential to ensure the accuracy and consistency of veneer preparation.

Laminate Cementation, Passed up to Now: An Overview

Having well-aligned and brightly white teeth are the two most preeminent components of an appleaing smile. During the 1980s, John Calamia introduced porcelain laminate veneers at New York University in the United States. Currently, Indirect restoration has become a common method for reconstructing damaged teeth. This involves using dental cement to attach the restoration to the tooth and fill the gap, preventing any displacement. The cementation process of ceramic laminates is a critical final step that requires careful handling. Cement thickness is one factor that influences the shear bond strength of luted veneers. Many factors govern cement thickness, one of them being the cement space provided either digitally or by the die spacer thickness and the number of coats applied. Success in this process has been attributed to a clinician's skill in proper case planning, selecting the appropriate ceramics, materials, and methods for cementation, conservative tooth preparation, impeccable finishing and polishing, and effective planning for ongoing restoration maintenance.

Digital workflow for prosthetic management of malpositioned implant in an adolescent patient: A 20-year follow-up.

Dental implants placed in adolescent patients pose a challenge to restore and maintain an esthetic outcome over longer period of follow-up. Maxillomandibular changes throughout adulthood may lead to complications such as implant infraocclusion and interproximal contact loss. This case report describes an alternate prosthetic treatment strategy for maxillary single implant placed in an adolescent patient in the esthetic zone with inappropriate implant axis and screw hole placement. With temporary restorations, the gingiva and soft tissues were shaped to imitate the emerging profile of the contralateral side. A zirconia screw-retained abutment was customized as a copy-mirror from the contralateral prepared tooth to mimic the exact shape and to avoid labiolingual over contour by computer-aided design/computer-assisted manufacture (CAD/CAM). The porcelain laminate veneer was bonded to the zirconia abutment. Porcelain adhesive approach was used instead of traditional principles of retention and resistance form of the abutment. A functional and esthetic outcome was achieved and maintained, while a minimally invasive procedure was implemented to use the malplaced implant instead of explanting it. The present report illustrates the prosthetic management of a malpositioned dental implant placed 20 years ago, utilizing a minimally invasive digital protocol.

Evaluation of E-max Porcelain Veneer Failures: A Retrospective Study.

Aim This retrospective study aimed to evaluate if E-max veneers over five years caused changes in gingival, periodontal health, and veneer failures. Background As aesthetic dentistry progresses, dental veneers are becoming increasingly popular in both general and specialized dental practices. Due to technological advancements in dental ceramics and adhesive systems, porcelain veneers have become a highly sought-after solution for improving aesthetics in dental patients. The success of porcelain laminate veneers, a commonly used method for aesthetic restoration, relies on various factors. E-max veneers are frequently utilized, with their long-term durability contingent upon factors such as color stability, resistance to abrasion, as well as good compressive, tensile, and shear strength, along with maintaining marginal integrity. Methodology In this study, data was collected through a checklist form used to record clinical parameters. The clinical parameters evaluated were inflammation and bleeding on probing (BOP). The gingival health was evaluated by gingival index, gingival color, texture, and bleeding on probing, and periodontal health was evaluated by the pocket depth and radiographic evaluations. Finally, the veneer was visually inspected for chipping, staining, and debonding history. The score for most of the cases ranged between 0-1, with only 10 cases displaying moderate gingival inflammation and BOP (Gingival Index 2). Siemens Orthopantomogram (OPG) systems were used for radiological evaluation and documentation of cases. E-max porcelain veneers were only included in the research. Results Out of 28 patients, each with 6-to-10-unit veneer cases was examined, 18 patients (64.3%) displayed healthy gingival status with no bleeding area recorded in none of the veneers amongst the 6 to 10 units. In 10 patients (35.7%) most of the veneers had inflamed gingival tissue that was bleeding on probing. The majority revealed the presence of stippling (92.9%), absence of recession (96.4%), and pocket depth (67.9%). Half of our participants had their veneer for more than five years (50%) and the majority presented with no significant changes in veneer recorded like marginal staining, debonding, or chipping (89.3%). Conclusion Multiple factors such as patient selection, proper treatment planning, and design, including material selection, play a significant role in the long-lasting success of ceramic veneers. The retrospective study indicated that proper oral hygiene measures are vital for the long-term sustainability of E max veneers.

CAD/CAM VENEERS FOR DIASTEMA CLOSURE USING DIGITAL WORKFLOW: A CASE REPORT

Objective: To present a clinical strategy to manage a case of diastema with CAD/CAM veneers using digital workflow. Case report: A healthy 32-year-old female patient presented to the Department of Prosthodontics with the chief complaint of spacing between the maxillary anterior teeth. Labial frenectomy was done to eliminate the etiological factor followed by prosthetic rehabilitation with porcelain laminate veneers using the digital impression employing CAD/CAM technology. Conclusion: The practical benefit of CAD/CAM technology are quality dental care allied with minimally invasive preparation, least possibility of errors and eliminating the need of multiple appointments.

Rehabilitation of Worn Anterior Teeth with Ceramic Veneers

Abstract The use of porcelain laminate veneers to solve esthetic and functional problems has proven to be a valid management option, especially in the anterior esthetic zone. Veneers are a reliable treatment option to modify the appearance of tooth position and form, to close diastema or cervical embrasures, or to change the tooth shade. Porcelain veneers are one of the best corrective options available considering biological, functional, mechanical, and esthetic points of view.

Clinical Longevity of Ceramic Veneers Bonded to Teeth with Aged Composite Restorations (Literature Review)

In this study the literature was reviewed to investigate the clinical outcome and longevity of anterior ceramic laminate veneers bonded to prior existing composite restorations. Clinical studies had investigated the survival of anterior ceramic laminate veneers adhered to teeth structures for at least 5 years of follow-up. This review has traced the studies which recorded the clinical longivity of porcelain laminate veneers bonded over old composite restorations; also the main reasons associated with restorations failure were searched. Sources in PubMed, Scopus, and Cochrane databases were searched in English language and without restriction on date. three reviewers screened titles and/or abstracts of 195 studies, all screened articles did not met the inclusion criteria of this review; which to have five years and more follow up in clinical retrospective or prospective studies, for that reason we have selected the most In vivo could possibly more related and the related In vitro studies. Within the limitation of this review, the clinical evidence for the practice of ceramic laminate veneers bonded over prior aged composite restorations is not strong. There is information lack about the long duration follow up for such treatment modality. The approach of replacing the prior existing composite restoration with new ones could be a wise option but using extended veneer design might be a wiser alternative. We recommend more clinical trials for long enough duration to evaluate the long success of ceramic laminate veneers that will be adhered to prior existing composite restorations.

Age and sex related change in tooth enamel thickness of maxillary incisors measured by cone beam computed tomography

BackgroundTo measure adequate enamel thickness of maxillary incisors in planning enamel reduction for a porcelain laminate veneer restoration in relation to chronological age and sex by using cone beam computed tomography (CBCT) in an Iraqi subpopulation.MethodsFrom 81 CBCT images, 324 maxillary incisors were examined. Enamel thickness was measured at both mesial and distal regions of the tooth in three different levels: cervical, middle, and incisal (occlusal) 1/3 at a sagittal section. Measurements were made for the following tooth areas using CBCT: facial enamel thickness at 1, 3, and 5 mm from the cementoenamel junction (CEJ), palatal enamel thickness at 5 mm from the CEJ (5 mm P), facial and palatal enamel thickness at the incisal edge (IFP), mid incisal enamel thickness (IET), and the incisal edge enamel-pulp distance (IEPD). Relationships of enamel thickness with age and sex were evaluated using Independent t-test, Mann–Whitney U-test and the Pearson correlation coefficient, a simple linear regression analysis used for statistical analysis.ResultsSignificant differences (P < 0.05) were found in terms of an inverse association between enamel thickness and chronological age at all measurements above the CEJ and the regression model for the mid-incisal enamel thickness was (R2 of 0.4). In contrast, there was an increase in IFP, palatal, and IPED enamel thickness with age. Also, significant differences were found in enamel thickness between males and females, the enamel being thicker in females in relation to facial enamel thickness, enamel palatal thickness above CEJ and IET, while for IEPD, the enamel thickness was greater in males compared to females.ConclusionThe measurements for enamel thickness outcome variables in relation to chronological age revealed significant differences for each measured distance and there were statistically significant differences in enamel thickness between males and females at all measurements except at IFP. These results demonstrate that CBCT can be used for noninvasive, accurate measurements of enamel thickness in both sex.

Effect of Thickness and Translucency on Color Change and Masking Ability of Ceramic Materials used for Laminate Veneers.

This study evaluated the effect of the thickness and translucency of lithium disilicatebased glass ceramics on resin composite substrates on color change and masking effect. Laminate veneers were fabricated using IPS e.max CAD (A1) blocks with two different light transmittance values (High translucent [HT], Low translucent [LT]). Slices of two different thicknesses (0.3 mm, 0.5 mm) were obtained (n=10) and laminate veneers were cemented on the resin composite substrates of two different shades (A2, A3.5). The color change (ΔE values) was evaluated with the CIELab color system using a spectrophotometer, while the masking effect was calculated. The data were analyzed using independent-samples t-test and two-way analysis of variance. The ceramic thickness and translucency had a significant effect on final color and masking. When HT was used, and the laminate veneer thickness decreased (0.3 mm), the masking effect in ΔE values were lower (p⟨0.05). The ΔE values (⟩3.7) were clinically unacceptable. With the increase in thickness, translucency of porcelain laminate veneers decreases showing better color masking ability. Veneer thickness seems to be more effective on the restoration's masking ability than the shade of the substrate and translucency. Cinically, in case a 0.5-mm or thinner laminate veneer is planned, tooth color, resin cement and ceramic type should be considered.

Survival of Partial Laminate Veneers and Categorical Covariates Affecting the Survival: A Systematic Review

Background: Partial laminate veneers (PLV) have been accepted widely among both clinicians and patients with their favorable specifications, such as conservativeness, superior esthetics, bond strength and durability, for three decades. Various esthetic and functional impairments spreading in a wide range may be restored with veneers instead of full contour crowns. Objective: Although advantages, partial laminate veneers are not free from complications and various factors can influence the service duration of these restorations. Methods: An electronic Pubmed/Medline and Google Academic search was conducted without time restriction, providing information on porcelain laminate veneer’s failure rate and survival. Assessment of the identified studies was performed by two independent reviewers. Clinical service durations and various types of failures were evaluated. Results: Debonding, fracture, discoloration of the porcelain; staining or disintegration of tooth-porcelain margin; hypersensitivity, secondary caries, pulp necrosis and the periodontal responses were the more frequently studied failures. The mean CFR was found as 8,22% per study. Enamel substrate, incisal overlapping and lithium disilicate veneers presented lower failure rates in comparison with dentine substrate, non-overlapping and feldspathic veneers. Conclusion: PLV’s have high survival rates. The overall survival of PLV restorations can be affected by several prognostic variables.

Shade selection for natural tooth color replication on porcelain laminate veneers

The final color of dental ceramics depends on different factors such as light source, substrate, and selected material (thickness, contour, and texture). Objective: To report a clinical case in which a predictable protocol is used to optimize the final color of porcelain laminate veneers. Case report: A male patient attended the dental clinic dissatisfied with the composite resin restorations made on his upper anterior teeth. After anamnesis and clinical examination, it was suggested that the resin restorations be replaced by laminated porcelain veneers. A diagnostic wax-up was performed. The mock[1]up was also used to evaluate the aesthetic length for replicating the details of the incisal edge and the shape and size of the embrasures. The shade was selected before composite resin removal to avoid dehydration of the dental substrate. A photograph was taken to guide the selection of colors in different thirds. After removing the restorations, another photograph was taken to evaluate the color of the substrate. The impression was taken with 000 retractor wire and addition silicone. The laminates were made with pressed ceramic and feldspathic porcelain veneers were subsequently applied by layering the layers of dentin, incisal edge and enamel based on the waxing diagnosis. After approval by the patient, a conventional cementation technique was performed. The occlusal adjustment was made with rubber polishing cups and the anterior and lateral guides were checked. Conclusion: The protocol recommended for successful selection of the color of a porcelain laminate relies on the combination of knowledge of concepts, resources such as shade guides, spectrophotometers, and photographs, and porcelain application and characterization techniques performed by the technician and luting techniques by the dentist.

Risk Factors with Porcelain Laminate Veneers Experienced during Cementation: A Review.

The clinical success of porcelain laminate veneers (PLVs) depends on many clinical and technical factors, from planning to execution, among which adhesive cementation is of significant importance. This procedure carries many risk factors if not optimally executed. The objective of this study was to document the clinical parameters affecting successful cementation procedures with a focus on the adhesive strength, integrity, and esthetics of the PLVs. A literature search was conducted through MEDLINE, complemented by a hand search using predefined keywords. Articles published in English between 1995 and 2023 were selected. According to this review, the success and longevity of PLVs rely in great part on the implementation of a precise cementation technique, starting from field isolation, adequate materials selection for adhesion, proper manipulation of the materials, the seating of the veneers, polymerization, and elimination of the excess cement. Several clinical steps performed before cementation, including treatment planning, preparation, impression, and adequate choice of the restorative material, could affect the quality of cementation. Scientific evidence suggests careful implementation of this process to achieve predictable outcomes with PLVs. The short- and long-term clinical success of adhesively luted PLVs is tributary to a deep understanding of the materials used and the implementation of clinical protocols. It is also contingent upon all the previous steps from case selection, treatment planning, and execution until and after the cementation.

Knowledge of Saudi dental students and interns towards luting cements and their applications in fixed prosthodontics

BackgroundEnhancement of students’ knowledge is essential in improving their clinical skills and performance. Thus, the curriculum should be prepared to achieve a better outcome. The current study aimed to determine the dental students’ and interns’ basic knowledge towards dental luting cements and their application in dental practice to improve the theoretical and clinical training sections.Materials and methodsA cross–sectional study was conducted among dental students and interns at three Colleges of Dentistry in the Kingdom of Saudi Arabia between September 2019–June 2020. An online questionnaire was used which included demographic data, questions about luting cement usage, cementation techniques, and commonly used cements in dental clinics. Descriptive analysis and chi–square test were used to show the association between level of dental education and the use of dental cements using SPSS software. The significance level was set at 5%.ResultsThe total respondents were 626 dental students/interns of whom 78.8% were undergraduate dental students. Participants who reported undergraduate studies as the source of information were 79.7%. The type of restoration was the main factor in luting cement selection (62.6%). Concerning the isolation technique in cementing laminate veneers, 49.7% used dri–angles, cotton rolls and saliva ejectors. Dual–cure resin cement was the most common cement used in all the mentioned restorations except in pressed porcelain laminate veneers and cement–retained implant–supported restorations.ConclusionsStudents’ knowledge and practice in managing dental implants and porcelain laminate veneers need to be improved. The selection of a luting agent for a given restoration by students and interns was based on the basic knowledge, available cement, and the type of restoration. Awareness towards the management of short prepared teeth and custom-made cast posts and cores is also limited.

Effect of Internal, Office, and Home Bleaching on Shear Bond Strength of Enamel to Porcelain Laminate Veneers

To compare the effect of office, home, and internal bleaching on the shear bond strength (SBS) of enamel to porcelain laminate veneers. A total of 36 extracted maxillary central incisors were randomly assigned to four groups: (1) no bleaching (control); (2) office bleaching with 40% hydrogen peroxide (HP); (3) home bleaching with 15% carbamide peroxide; and (4) intracoronal bleaching with sodium perborate (SP) using the walking bleaching technique. All teeth were separately immersed in artificial saliva for 14 days. The enamel surface was then reduced by 0.5 mm, and IPS e.max Press ceramic discs were bonded using a resin cement. After 24 hours, all specimens were thermocycled (5,000 cycles, 5°C to 55°C). The SBS was measured using a universal testing machine, and the failure mode was determined using a stereomicroscope. One-way ANOVA and Tukey honest significant difference tests were used for data analysis (P < .05). A significant difference was noted among the groups (P < .001). The highest SBS was noted in the control group (15.71 ± 5.39 MPa). The mean SBS in the office bleaching group (12.30 ± 4.64 MPa) was almost the same as the control. The lowest mean SBS belonged to the home bleaching group (5.39 ± 3.99 MPa). The mode of failure was adhesive in all four groups. If bleaching is intended to be followed by porcelain veneers, the office bleaching technique with 40% HP is recommended. Delaying the bonding procedure for 2 weeks does not appear to be effective with home or intracoronal bleaching.

Aesthetic Management of Anterior Midline Diastema

This case report describes a treatment using lithium disilicate in rehabilitating maxillary anterior with midline spacing. This conservative treatment requires fewer clinical sessions along with detailed clinical protocol, precise indications, and laboratory procedures. The result concludes that ceramic veneers not only restore harmony and proportion in a patient’s smile but also prove to be an excellent treatment for an anterior aesthetic zone.&#x0D; Today, with the influence of social media or social technologies, the concern about facial aesthetics and the demand for cosmetic procedures grows rapidly.[1] Hence, the requirement for aesthetic dental treatments and the creation of beautiful smiles has increased for the re-establishment of oral health and function.[2] The presence of anterior spacing or diastema is one of the factors that affect the smile of an individual. This has become the most common aesthetic complaint of patients.[3] According to Keene (1963), a midline diastema is an anterior midline separation between the proximal surfaces of consecutive teeth that is greater than 0.5 mm.[4] There was also a report that states the maxilla has a higher occurrence of midline diastema than the mandible.[5] According to Oquendo et al., the objectives of treating diastemata are to achieve a stable and effective occlusion as well as a tooth form that is harmonious with the surrounding teeth, arch, and facial form. The result needs to be balanced and appealing to the patient.[6]&#x0D; The options to correct midline diastema range from composite resins to ceramics. Time restrictions, the desire for fast aesthetic results, or the perception of the social stigma connected with their age and wearing braces are some of the reasons why patients may choose not to have orthodontics to close diastemas.[7]&#x0D; Due to the preservation of dental structures, reduced price compared to ceramics, reversibility, and straightforward process, the composite resin was once the preferred choice for diastema closure.[8] However, it was shown that secondary caries, loss of repair, pigment impregnation, fracture, marginal flaws, and a high level of colour instability all contribute to their high failure rate.[9]&#x0D; For patients looking for long-lasting therapy and with high aesthetic standards, ceramics have become the material of choice. Although zirconia has greater mechanical strength, lithium disilicate has greater translucency, making the two materials the most popular. Porcelain laminate veneers introduced by Charles Pincus in 1938 are a thin shell of ceramic and these can be bonded to the facial surface of anterior teeth using bonding agents and dual-cure cements.[10] Buonocore in 1955 introduced the acid etch technique. Bowen in 1958 introduced silica resin direct filling material. Furthermore, with the introduction of improved bonding agents in the 1980s when coupled with the silanization of veneers, the results of porcelain laminate veneers have become more predictable.[11] Considering the little dental preparation and outstanding aesthetic result, this surgery is therefore quite conservative. These materials acquire enamel's strength when they are adhered to it, becoming just as durable as the native tooth structure.[12] According to Peumans et al. (2004), survival rates have ranged from 92% at 5 years to 64% at 10 years. The importance of adequate case selection and procedure is stressed by the extremely high survival rates of carefully implanted PLVs (porcelain laminate veneer) of over 90% after 9 years (Strassler &amp; Nathanson, 1989; Dunne &amp; Millar, 1993).[13] This article reports a case of aesthetic rehabilitation of anterior diastema closure using lithium disilicate porcelain veneers.

Debonding of LDSVs utilising Er,Cr:YSGG laser irradiation with fractional technique: an in vitro study.

The removal of porcelain laminate veneers with rotary instruments could be accompanied by microfractures because differentiation of the veneer from the dental structure and resin cement is not a highly selective procedure. This can lead to scratches and overheating of the enamel and patient discomfort. Therefore, this in vitro research aimed to examine the effectiveness of the 2790 nm Er,Cr:YSGG laser utilizing a fractional technique to debond lithium disilicate veneer. Six groups of 30 extracted permanent bovine mandibular incisors were selected. Twenty-five samples, G1-5, (n = 5) laser-irradiated groups, and the last five samples (C) were considered the control group. The tested groups were irradiated with 3-5 W output power of Er,Cr:YSGG laser for time intervals of 50 s. During irradiation, the temperature in the pulp chamber was monitored using a thermocouple connected to a digital multilogger thermometer inside the sample's pulp chamber. Subsequently, the shear bond strength was measured for all groups. Furthermore, the remaining adhesive index was measured using a stereomicroscope, the area was analysed, and then transformed into scores. Finally, one untreated sample and two samples of the highest power value from laser-treated groups were examined using a scanning electron microscope (SEM) for their surface morphology. All debonding protocols were safe regarding intrapulpal temperature increment. The highest temperature elevation was recorded at 5 W, which increased by 1.7 °C. Considering the shear bond strength measurement, there was a significant reduction after laser irradiation for G1-5 compared with group C. Er,Cr:YSGG laser with a fractional technique can be used successfully for veneer removal. Besides safe temperature rising, veneers can be reused because there was neither a fractured specimen during the whole study nor major irregularities or cracks shown in SEM pictures analysis for the veneer surfaces; thus, they can be removed quickly, safely, and comfortably using Er,Cr:YSGG. © 2023 Australian Dental Association.
