Dental hypersensitivity is a common concern for many patients, often caused by the exposure of dentinal tubules. Various treatments have been suggested in the past, such as flowable composite restorations, medicated toothpastes, and mouthwashes, with the aim of reducing sensitivity. However, these methods often fall short in fully addressing the issue, as they do not adequately seal or protect the open dentinal tubules, leaving patients still vulnerable to discomfort.
This brings us to a more effective approach i.e indirect and semi-direct bonded restorations, such as occlusal veneers. These restorations offer several benefits over traditional treatments, providing a more durable, aesthetic, and minimally invasive solution to hypersensitivity.
The Ultrathin bonded lithium disilicate posterior occlusal veneers or Semi direct composite occlusal veneers represent a conservative alternative to the traditional composites and complete coverage crowns for the treatment of occlusal wear. So these case reports emphasis on stable performance of occlusal veneers with 18 months follow-up in the patients with occlusal wear without loss of vertical dimension.

Key Message: Ultra-thin occlusal veneers are game changers in full mouth rehabilitation as well as in occlusal correction procedures especially when symptomatic relief from sensitivity and tooth preservation are considered altogether.
