Influence of bruxism on survival of porcelain laminate veneers

Abstract

Objectives: This study aims to determine whether bruxism and the use of occlusal splints affect the survival of porcelain laminate veneers in patients treated with this technique. Material and Methods: Restorations were made in 70 patients, including 30 patients with some type of parafunctional habit. A total of 323 veneers were placed, 170 in patients with bruxism activity, and the remaining 153 in patients without it. A clinical examination determined the presence or absence of ceramic failure (cracks, fractures and debonding) of the restorations; these incidents were analyzed for association with bruxism and the use of splints. Results: Analysis of the ceramic failures showed that of the 13 fractures and 29 debonding that were present in our study, 8 fractures and 22 debonding were related to the presence of bruxism. Conclusions: Porcelain laminate veneers are a predictable treatment option that provides excellent results, recognizing a higher risk of failure in patients with bruxism activity. The use of occlusal splints reduces the risk of fractures. Key words:Veneer, fracture, debonding, bruxism, occlusal splint.

Ceramic Veneers and Direct-Composite Cases of Amelogenesis Imperfecta Rehabilitation

“…In addition, good oral hygiene and absence of parafunctional habits led to the choice of ceramic veneers. A clinical study by Granell-Ruíz and others 25 found that the presence of fractures and debonding of ceramic laminate veneers increased considerably in patients with bruxism. The mock-up indicated no need to extend the preparation depth because the space necessary for the laminate already existed.…”

Retrospective evaluation of extended heat‐pressed ceramic veneers after a mean observational period of 7 years

“…[1][2][3]5 The heterogeneity of the reported data is attributed to the different failure criteria used and different preparation designs (with/without incisal overlap), adhesive luting techniques and patient-related factors (eg, age, gender, and bruxism). [5][6][7][8][9][10][11][12][13] Higher failure rates have been reported in clinical studies, especially in patients with symptoms of bruxism activity. 12,13 Among other factors, the amount of exposed dentin has been discussed as a risk factor for ceramic veneer restoration clinical failure.…”

Microveneers and digital smile designer: Planning for a patient with bruxism: A 1-year follow-up

“…The presence of the tightening imposes the use of mechanisms to allow greater longevity to the restorations teeth, and the use of the bite stabilizing plate is an important therapeutic measure to avoid the fracture of the ceramics. [17] Although follow-up studies of restorations performed with lithium disilicate are scarce in the literature, this treatment option is safe because conventional lithium disilicate has proved to be effective and reliable in the short-to-medium term. The choice of this material may represent a valid option in many clinical situations, offering biological, technical, and esthetic advantages.…”

“…In such cases, meticulous planning has to be done, including the preparation of restorations in respect to the occlusal principles, and at the same time soften the impact of bruxism through a bite stabilizing plate. [17] The aim of this study is to present a clinical case of an esthetic and functional rehabilitation, previously planned and virtually built through DSD, on a patient with parafunctional habit.…”
