Aesthetic Rehabilitation of Fluorosed Teeth with Indirect Laminate Veneers- A Case Report

Dental fluorosis is a condition caused by chronic ingestion of excess fluoride during tooth enamel formation. This induces subsurface porosities to varying extents depending on the severity of fluorosis. Such patients consult dentist mainly for aesthetic reasons. Selection of an appropriate treatment plan for such cases depends on the severity of the condition. Laminate veneers is a conservative method of restoring the appearance of discoloured, pitted teeth, and teeth with diastemas that provide extremely good aesthetic results. They are considered as the treatment of choice for moderate to severe cases of dental fluorosis given the optimum aesthetics, wear resistance, biocompatibility, and long-term results of these veneers.

Faţetarea directă cu materiale compozite a leziunilor eroziv-abrazive – prezentare de caz

The treatment of abrasive and/or erosive dental lesions is a conservative one. A frequently used treatment method for this type of lesions is the direct and indirect laminate veneer res­to­ra­tion with composite resins. In the direct technique, the material is inserted by the dentist inside the preparation, so that the treatment is performed in a single session. Direct com­po­site veneers has other advantages, including the com­plete morphofunctional restoration of the tooth, very good aesthetic appearance, simple working technique, and the low cost for the patient. The treatment of dental wear must always be accompanied by the removal of the etiological factors and the education of the patient re­gar­ding oral hygiene and diet, in order to maintain the ob­tained results in time.

Smile makeover with porcelain laminate veneer: A case report

Pincus is credited for evolution of porcelain veneers. He attached the thin labial porcelain veneers temporarily with denture adhesive powders to improve dental esthetic appearance. Improvement of patient’s lost natural dental esthetics have become important goal of discipline of dentistry and credited for wide ranging applications from improving common man’s appearance to filmstars. Esthetic problems may be result of interplay of complex factors like color, shape, and structural and position abnormalities of anterior teeth. Laminate veneers are used for purpose of improving esthetic deficiencies and discolorations as well as existing abnormalities.Successful application of porcelain veneers depends on multiple factors such as the clinical and laboratory steps involved, along with the understanding of the scientific background of procedure.Conservative and esthetic approaches, such as direct and indirect laminate veneer restorations are most preferred way chosen by dentist across world to improve compromised esthetics of human beings. Technological advancements such as intraoral scanner for impression making have significantly improved the success of prosthesis.

Randomized clinical trial on indirect resin composite and ceramic laminate veneers: Up to 10-year findings

ObjectivesIn this randomized split-mouth clinical trial the survival rate and quality of survival of indirect resin composite and ceramic laminate veneers were evaluated. MethodsA total of 48 indirect resin composite (Estenia; n = 24) and ceramic laminate veneers (IPS Empress Esthetic; n = 24) were placed on maxillary anterior teeth. Veneer preparations with incisal overlap were performed using a mock up technique. Survival of the restoration was considered the primary outcome measure and reported using Kaplan-Meier statistics and survival curves compared by means of Log Rank (Mantel-Cox) test. After luting, restorations were evaluated by calibrated operators at baseline and every year thereafter, using modified USPHS criteria and compared by means of Mann-Whitney U test. ResultsIn total, 6 failures were observed, consisting of debonding (n = 3) and fracture (n = 3), all in the group of the indirect resin composite laminate veneers. Cumulative chance on survival after 10 years of the indirect resin composite and ceramic veneers was 75% (se 3,8%) and 100% respectively (p = 0.013). Of the surviving 42 laminate veneers, the variables ‘color match’ (p = 0.002), ‘surface roughness’ (p = 0.000), ‘fracture of the restoration’ (p = 0.028), and ‘wear of the restoration’ (p = 0.014), were significantly less favourable among the composite laminate veneers as well. ConclusionsThe ceramic veneers on maxillary anterior teeth in this study performed significantly better compared to the composite indirect laminate veneers after a decade, both in terms of survival rate and in terms of quality of the surviving restorations. Clinical RelevanceWhen indicated, anterior ceramic laminate veneers may be preferred over indirect composite laminate veneers.

Direct composite veneers -restoring esthetics by procuring patient demand: a case report

Re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. New treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. Most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for anteriors where aesthetics is really important. Laminate veneers are restorations which are envisioned to correct existing abnormalities, esthetic deficiencies and discolorations. Laminate veneer restorations may be processed in two different ways: direct or indirect. Direct laminate veneers have no need to be prepared in the laboratory and are based on the principle of application of a composite material directly to the prepared tooth surface in the dental clinic. Indirect laminate veneers may be produced from composite materials or ceramics, which are cemented to the tooth with an adhesive resin. In this case report, direct composite laminate veneer technique used for patients with esthetic problems is described and six-month follow-up are discussed. As a conclusion, direct laminate veneer restorations may be a treatment option for patients with the esthetic problems of anterior teeth in case similar to those reported here.

Evaluation of Esthetic Rehabilitation of Teeth with Severe Fluorosis Using Direct and Indirect Laminate Veneer: A Case Report

Laminate veneers is a conservative method of restoring the appearance of discolored, pitted teeth, and teeth with diastemas that provide extremely good esthetic results. A 21-year-old male patient with staining in maxillary and mandibular anterior teeth had reported for esthetic rehabilitation. This article presents the stages of esthetic rehabilitation of a patient with severe fluorosis including direct Laminte (composite) veneering for mandibular anterior teeth and indirect Laminate (ceramic) veneering for maxillary anterior teeth. The patient was satisfied with the enhanced esthetic appearance. One year follow up have displayed acceptable outcomes and esthetic appearance.

WITHDRAWN: Direct versus indirect veneer restorations for intrinsic dental stains.

BACKGROUND: Patients with discoloured teeth frequently present to the dentist requesting restorations designed to improve their appearance. For teeth that are sound, this might include the use of a veneer restoration. The veneer acts as a thin layer of a material covering the labial surface of a tooth and can be applied directly to the tooth, or by using indirect methods. OBJECTIVES: To examine the effectiveness of direct versus indirect laminate veneer restorations. SEARCH STRATEGY: The following electronic databases were searched: The Cochrane Oral Health Group's Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL), (The Cochrane Library Issue 3, 2002), MEDLINE (1980 to 19/11/2002) and EMBASE (1980 to 19/11/2002). There was no restriction on language. SELECTION CRITERIA: All randomised controlled trials (RCTs) of participants with permanent anterior teeth suitable for restorations using laminate veneers, comparing direct (different composite materials) and indirect techniques for making dental veneers. The indirect restorations may be either composite or porcelain. The primary outcome was restoration failure. DATA COLLECTION AND ANALYSIS: Assessment of relevance and validity and data extraction were conducted in triplicate. Authors of the primary studies were contacted to provide additional information as necessary. MAIN RESULTS: Six full publications were screened as being potentially relevant to the review, only one trial was found to meet the review's inclusion criteria. Although the trial met the review's inclusion criteria with regard to participant characteristics, interventions and outcomes assessed, problems with the reporting of the data prevented any statistical analysis of the results. REVIEWER'S CONCLUSIONS: There is no reliable evidence to show a benefit of one type of veneer restoration (direct or indirect) over the other with regard to the longevity of the restoration.

Direct Conservative Esthetic Restoration - A Case Report

Rehabilitation of lost dental aesthetic is one of the most important concerns for contemporary dentistry. Conservative treatment modality along with aesthetic approaches, such as direct and indirect laminate veneer restorations were the treatment of choice. Laminate veneers are restorations to correct aesthetic deficiencies and discolorations. Direct laminate veneers involve the application of a composite material directly to the prepared tooth surface. This case report discusses the composite mirroring using direct composite laminate veneer technique application to the re-established the aesthetic problems related to discolorations in anterior region.

Direct composite laminate veneers: three case reports.

Re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. New treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. Most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for anteriors where aesthetics is really important. Laminate veneers are restorations which are envisioned to correct existing abnormalities, esthetic deficiencies and discolo-rations. Laminate veneer restorations may be processed in two different ways: direct or indirect. Direct laminate veneers have no need to be prepared in the laboratory and are based on the principle of application of a composite material directly to the prepared tooth surface in the dental clinic. Indirect laminate veneers may be produced from composite materials or ceramics, which are cemented to the tooth with an adhesive resin. In this case report, direct composite laminate veneer technique used for three patients with esthetic problems related to fractures, discolorations and an old prolapsed restoration, is described and six-month follow-ups are discussed. As a conclusion, direct laminate veneer restorations may be a treatment option for patients with the esthetic problems of anterior teeth in cases similar to those reported here.

Influence of anatomic reference on the buccal contour of prosthetic crowns

During clinical practice, when performing prosthetic rehabilitation with single crowns, improper reproduction of the dental contour by the dental laboratory is a common occurrence. Therefore, the present study evaluated the fidelity of the reproduction of the buccal contour in an upper left canine performed by three Dental Prosthesis Technicians (DPT) using the indirect laminate veneer technique. First, the DPTs confected the veneers based on a model obtained from the upper arch of a dental dummy, containing a replica of an upper left canine with a prosthetic preparation for a laminate veneer. Then, the same DPTs received other identical models, now with the replica of the upper left canine with no preparation, to be used as an anatomical reference for confecting the laminate veneers. The laminate veneers were then bonded to the plaster models and had their buccal contour individually measured. Measurements were also made of the buccal contour of the reference canine. The data were analyzed by ANOVA and the t-test (p = 0.05). Results showed 100% of buccal overcontour when the laminate veneers were compared to the reference canine, regardless of which DPT confected the veneer and regardless of using or not the anatomical reference. The DPTs who participated in the present study were unable to acomplish a faithful anatomical reproduction of the buccal contour, creating an overcontour in all samples. This situation may be responsible for increasing the probability of periodontal and esthetic harm in clinical practice.

Fracture strength of direct versus indirect laminates with and without fiber application at the cementation interface

Objectives This study compared the fracture strength of direct and indirect resin composite laminate veneers and evaluated the effect of a bidirectional E-glass woven fiber application at different locations at the cementation interface. Methods Standard preparations on canines ( N = 50, 10 per group) were made using a depth cutting bur (0.7 mm depth) designed for laminate veneer restorations. Forty indirect laminates using a highly filled polymeric material (Estenia) and 10 direct laminates (Quadrant Anterior Shine) were prepared according to the manufacturer's instructions. Bidirectional E-glass woven-fiber sheet (0.06 mm) (Everstick) was applied at different locations at the cementation interface. The control group received no fibers. The specimens were stored in water at 37 °C for 1 month prior to fracture testing performed in a universal testing machine where the load was applied from the incisal direction at 137° (1 mm/min). Results No significant differences were found between the five groups ( P > 0.01) (one-way ANOVA). While indirect laminate veneers showed mean fracture strength of 247 ± 47 N, direct laminate veneers revealed 239 ± 104 N. The use of E-glass fibers at the cementation interface at different locations did not increase the fracture strength significantly (286–313 N) ( P > 0.01). Failure analysis showed mainly cohesive fracture of the veneer restoration (20/50) and adhesive failure between the cementation interface and the laminate with fiber exposure (19/50) covering more than half of the restorations. Significance Direct and indirect resin composite laminate veneers showed comparable mean fracture strengths. The use of E-glass woven-fiber sheet at the cementation interface did not increase the fracture strength of the polymeric laminate veneers.
