Laboratory Survey

ABSTRACT Aim The aim of the survey conducted in dental laboratories was to evaluate the current trend in fabricating a full ceramic restoration for discolored anterior teeth through a questionnaire and personal interaction with the dental technician. Materials and Methods The survey questionnaire consisted of 20 questions aimed toward the current trend in fabricating a full ceramic restoration for discolored anterior teeth. This questionnaire was validated by a panel of senior prosthodontists and technicians and was sent to 32 dental technicians in Mumbai and Navi Mumbai. Results and conclusion The results of the study showed that majority of the dental technicians preferred taking the stump shade themselves by visiting the clinic or inviting the patient to the laboratory. Majority of the dental technicians preferred using lithium disilicate material and its medium opacity ingots to fabricate restorations by the layering technique for masking discolored anterior teeth. Majority of the technicians believed that their dentists did not use try-in paste prior to luting of the restoration. Clinical significance This survey would help to improve the rapport between the clinicians and dental laboratories and optimize the esthetics of the restorations fabricated for anterior discolored teeth.

Treatment Prognosis

Management of severe worn dentition in patients with bruxism is challenging as a result of the loss of tooth structure and occlusal vertical dimension, temporomandibular implications, tooth hypersensitivity, and masticatory or aesthetic impairment. This case describes the 4-year follow-up clinical evaluation of a full mouth tooth-supported rehabilitation made on a 66-year-old man with bruxism and tooth wear, with aesthetic complaints and compromised masticatory function. The prosthetic treatment was planned with a digital smile design and a mock-up technique for an aesthetic and minimally invasive approach using lithium disilicate pressed and layered veneers on anterior teeth, posterior CAD/CAM lithium disilicate overlays with facial coverage, and CAD/CAM monolithic zirconia crowns with facial feldspathic ceramic on maxillary and mandibular canines and first molars in order to ensure the occlusal stability at the increased occlusal vertical dimension. After 4 years of function, no complications were registered. The choice of an appropriate material for the rehabilitation of these patients is essential to improve treatment prognosis and should be guided by mechanical and aesthetical properties. The use of four-point occlusal stabilization with CAD/CAM high strength monolithic zirconia crowns combined with ceramic veneers and overlays appears to be a reliable treatment option that enhances aesthetics and minimizes the occurrence of ceramic fractures, ensuring the treatment prognosis and predictability.

Abstract Objectives Primary aim of this study was to evaluate survival rate of lithium disilicate veneers in upper and lower anterior teeth. Secondary aims were to evaluate changing in proportions of teeth before and after restorations and to assess mean thickness of the veneers. Materials and Methods Seventy-nine upper and lower lithium disilicate veneers were made in 13 patients with worn teeth. Mean follow-up was 3 years. To perform anterior definitive rehabilitations, malocclusions and loss of vertical dimension were treated by full mouth rehabilitations to obtain proper occlusal conditions. Veneers were made of lithium disilicate core and fluorapatite-based ceramic stratification. Survival rate was calculated by Kaplan–Meier analysis. Changing in teeth proportion before and after restorations was analyzed by a paired t-test. Descriptive statistics of thickness values were also performed. Results One case of detachment was observed with a 98.7% survival rate. Teeth’s proportions were preserved although the first upper right incisor and canine changed in dimension. Conclusions Lithium disilicate veneers in esthetical rehabilitations of worn teeth proved to be an effective way of treatment in a medium follow-up of 3 years. Proportions seemed to be maintained with a minimum dental removal.

Rehabilitation of worn dentition is a challenging task because several predisposing factors may be included in the pathogenesis. The treatment options and process should be carefully considered based on the clinical condition and patients’ requirements. This case report represents the esthetic rehabilitation of a 68-year-old patient who exhibited severely worn teeth caused by attrition and erosion. After clinical evaluation, 3 mm increase in occlusal vertical dimension was planned with partial lithium-disilicate ceramic restorations as laminate veneers for anterior teeth and vonlays (onlays with veneer extentions) for posterior teeth in maxilla. The adaptation of the patient to the increased occlusal vertical dimension was tested for 1 month by provisional direct composite restorations. As the patient did not show any discomfort, definitive restorations were completed. The patient was satisfied with the esthetics and functionality of her new dentition.

Laminate Veneers

SUMMARY Laminate veneers have been routinely used to restore and enhance the appearance of natural dentition. The traditional pathway for fabricating veneers consisted of making conventional polyvinyl siloxane impressions, producing stone casts, and fabricating final porcelain prostheses on stone dies. Pressed ceramics have successfully been used for laminate veneer fabrication for several years. Recently, digital computer-aided design/computer-aided manufacturing scanning has become commercially available to make a digital impression that is sent electronically to a dental laboratory or a chairside milling machine. However, technology has been developed to allow digital data acquisition in conjunction with electronically transmitted data that enables virtual design of restorations and milling at a remote production center. Following the aforementioned workflow will provide the opportunity to fabricate a physical cast-free restoration. This new technique has been reported recently for all-ceramic IPS e.max full-coverage pressed-ceramic restorations. However, laminate veneers are very delicate and technique-sensitive restorations when compared with all-ceramic full-coverage ones made from the same material. Complete digital design and fabrication of multiple consecutive laminate veneers seems to be very challenging. This clinical report presents the digital workflow for the virtual design and fabrication of multiple laminate veneers in a patient for enhancing the esthetics of his maxillary anterior teeth. A step-by-step process is presented with a discussion of the advantages and disadvantages of this novel technique. Additionally, the use of lithium disilicate ceramic as the material of choice and the rationale for such a decision is discussed.

The aim of this study was to identify the protocols used for indirect anterior and posterior restorations on dental substrate, used in Dental Prosthesis Specialization Courses and by professionals already specialists in the area. Two groups participated of this study, the first composed of 40 dental surgeons specialized in Dental Prosthesis and the second by 7 Specialization Courses of the same area. Both answered the same questionnaire about ceramic systems and cementation used for unitary indirect restorations of posterior and anterior teeth, on dental substrate in color A2 of the VITA scale (Vita Zahnfabrik). It was observed that among the prosthodontists, the majority (82.5%) opted for lithium disilicate for indirect restorations of anterior teeth and metalloceramics (32.5%) for posterior teeth. Alumina and felspathic were the least used materials in anterior and posterior regions. Dual resin cement was the most used for anterior teeth (57.5%) and posterior teeth (45%). Among the schools of Specialization and Updating courses, lithium disilicate (86%) was the first choice for anterior teeth and, for posterior teeth, zirconia (72%). Regarding cementation, both in the posterior and in the anterior regions, dual resin cement was the most used. From this survey of the protocols used, it was possible to identify that the two realities are similar, especially in the anterior region with preference for lithium disilicate, emphasizing the importance of knowledge of the materials available in the market.

Infiltration Anesthesia

Background: Separation methods of local anesthesia to diffuse and vascular must significantly affect the clinical effect of adrenaline containing local anesthetic (mepivacaine). The aim of this prospective, randomized, controlled studies µAde was to compare the degree of anesthesia of intact upper lateral incisor the cartridge ¼ 3% mepivacain without epinephrine in the group after the infiltration and after intraligamentary anesthesia (ILA) in the experimental group. Methods: Anesthesia performed computer syringe Sleeper One 86 subjects aged 20-23 years. In all cases, aspiration was performed. With pulp tester IVN-01 measured the pain threshold incisors and canines in microamperes during the anesthetic effect. Results: Reference level of all researched teeth (86 subjects) was ranged from 1 to 10 µA. Uniform pain threshold increase to 95 (±20) µA by 5 min. watched during infiltration anesthesia then this value gradually descended to reference level (by 20 min.). Peak single increase of pain threshold to 55 (±8,9) µA occurred immediately after 1st minute of ILA, then this value subsequently drops to reference level (10 µA) by 20 minutes. Difference between groups of infiltration and intraligamentary anesthesia (ILA+ red) and (ILA – green) presented on Chart 6. Conclusions: Infiltration anesthesia with mepivacaine without epinephrine smoothly diffusely increased the pain threshold of the front teeth, reaching a significant, maximum effect by 5 minutes. Intraligamentary injection immediately after administration created a peak increase in pain sensitivity at a lower level, almost without the participation of the diffuse component.
