Objective To evaluate the effect of ceramic thicknesses, bonding surface (enamel vs. dentin), and preparation design (box vs. no box) on the fatigue survival and failure load of minimally invasive full‐veneer restorations. Materials and Methods Human‐premolars (n = 60) were divided into five test groups (n = 12). All teeth received full‐veneer preparation with the following occlusal/labial thicknesses: standard: 1.5/0.8 mm; thin: 1.0/0.6 mm; ultrathin 0.5/0.4 mm. Preparations for each ceramic thickness were refined in enamel (E‐1.0 and E‐0.5) or dentin (D‐1.5, D‐1.0, and D‐0.5). Control groups DB‐1.5, EB‐1.0, and EB‐0.5 received box preparations. Monolithic lithium disilicate restorations (IPS‐e.max‐Press, Ivoclar Vivadent) were adhesively cemented (Syntac‐Classic/Variolink‐II, Ivoclar Vivadent) and subjected to cyclic mechanical loading (F = 49 N, 1.2 million cycles) with simultaneous thermocycling (5–55°C). All specimens were exposed to single load‐to‐failure. Pair‐wise differences were calculated by using a linear regression model and Student–Newman–Keuls method (p < 0.05). Results All full‐veneers of group D‐1.5, E‐1.0, E‐0.5, DB‐1.5, EB‐1.0, and EB‐0.5 survived fatigue. Two full‐veneers (D‐1.0 and D‐0.5) revealed cracks during fatigue, resulting in an overall fatigue survival rate of 98.1%. Mean load‐to‐failure values (N) were as followed: 1005 (D‐1.5); 866 (D‐1.0); 816 (D‐0.5); 1495 (E‐1.0); 1279 (E‐0.5); 1129 (DB‐1.5); 1087 (EB‐1.0); and 833 (EB‐0.5). Irrespective of ceramic thicknesses, enamel‐based full‐veneers resulted in higher failure loads than dentin‐based restorations. Box preparation reduced the failure loads of thin and ultrathin enamel‐based restorations. Conclusion All tested monolithic lithium disilicate full‐veneer restorations exceeded physiological masticatory forces. Minimally invasive full‐veneer restorations with enamel as a bonding surface and a non‐retentive preparation design showed superior performance. Clinical Significance Enamel‐based non‐retentive full‐veneers made of monolithic lithium disilicate may serve as a reliable and esthetical minimally invasive treatment option for premolars.

Background and objectives: Porcelain-fused-to-metal (PFM) prostheses are considered the gold standard for the replacement of missing teeth, however, these have several drawbacks. Therefore, lithium disilicate (LDS) prostheses have been introduced for the construction of fixed crowns and bridges. The aim of this systematic review was to ascertain the long-term survival of LDS fixed prostheses in comparison to other materials. Materials and methods: The focused question was ‘In patients who have undergone prosthodontic treatment (participants), what are the overall survival rate of lithium disilicate (LDS) crowns and fixed bridges; and how do they relate to survival rates of non-LDS similar restoration are the survival and com-plication rates (outcomes) of LDS-based fixed prostheses with complete coverage (intervention) higher or lower when compared to non-LDS materials (controls)?’. An electronic search was conducted in PubMED/Medline, EMBASE, Google Scholar, and ClinicalTrials.gov for articles published between January 2006 and August 2022 using appropriate MeSH terms and keywords. The following types of studies were included: (1) All types of prospective clinical studies; (2) Clinical studies focusing on the survival of fixed LDS bridges and crowns; (3) Studies using natural teeth with complete coverage as abutment for fixed LDS bridges and crowns; and (4) Studies in English. The following studies were excluded: (1) Laboratory/in vitro studies and studies on LDS prostheses with no description of outcomes or survival rates; (2) Commentaries; (3) Letters to the editor; (4) Reviews; and (5) Internal data from manufacturers. The data from included studies were extracted and the risk of bias was assessed within the studies using ROBINS-I. Results: A total of 25 studies were included in this systematic review. The overall 5-year and 10-year survival rates were of 95–100% and 71.4–100%, respectively. Generally, three-unit bridges had a significantly lower survival rate over 5 and 10 years compared to single-unit crowns. Overall, the risk of bias in the included studies was moderate. Conclusions: The LDS-based complete coverage prostheses have a survival rate ranging between 48.6% and 100%. Furthermore, due to the lack of comparative studies, the long-term function and survival of LDS prostheses compared to other material prosthesis (PFM and ZrO) is debatable.

BackgroundSuccessful periodontal therapy can lead to poor esthetic results, especially in the anterior region, for which there are treatment options such as direct composite or indirect veneer restorations. Until now, there are no data describing the long‐term results of veneer restorations in periodontally treated patients. The aim of this retrospective study was to evaluate the outcome of anterior porcelain veneer restorations in periodontally compromised and noncompromised patients.MethodsPeriodontally healthy and periodontally compromised patients, who had received anterior veneer restorations at least 5 years ago, were invited to a follow‐up examination. Groups were divided according to their periodontal diagnosis (periodontally healthy, stage I/II, stage III/IV). Tooth loss, veneer loss, biologic parameters, and complication rates were examined. Also, veneers were evaluated according to modified United States Public Health Service criteria.ResultsA total of 68 patients with 312 veneers were examined with a mean follow‐up time of 8 years. Veneered teeth in patients with periodontitis stage III/IV showed no difference regarding tooth‐specific, overall, and functional veneer survival when compared to periodontally healthy patients (Kaplan–Meier analyses). In Cox regression analysis, follow‐up time had an impact on complications and veneer loss, whereas periodontal diagnosis showed no significant influence on the survival of restorations. Comparative tests showed that patients with severe periodontitis at baseline have slightly lower veneer survival rates after 8 years and slightly higher complication rates after 13 years.ConclusionLong‐term results and complication rates of veneer restorations in periodontally compromised patients are comparable to periodontally healthy patients over a mean follow‐up of 8 years.
