Purpose: To describe the digital workflow applied for restoring a severely worn dentition with minimally invasive CAD/CAM resin nano-composite restorations.
Materials And Methods: A 40-year-old male in good general health and with full-arch dentition suffered from dentin hypersensitivity and wanted to improve the esthetics of his worn anterior teeth. The dental wear can be described as general, grade 3, according to the Tooth Wear Index,27 with more wear in maxillary than in mandibular teeth. Signs and symptoms were typical for a chemical type of wear, with some mechanical wear also apparent. No functional problems, eg, impaired chewing, were present. On the OHIP-49 questionnaire, the patient expressed a reduced quality of life. The goal of the treatment was to reconstruct the anatomical form of the teeth as far as possible, thereby also improving quality of life. Due to the rather large volume of lost tooth tissue per tooth, indirect treatment using CAD/CAM resin nano-composite restorations (LAVA Ultimate, 3M Oral Care) was applied.
Results: The seating of the CAD/CAM resin nano-composite restorations (LAVA Ultimate, 3M Oral Care) restorations was considered precise.
Conclusion: In the treatment of severe tooth wear, the described digital workflow using CAD/CAM restorations for occluding restorations and direct composite materials in the esthetic zone is a potential treatment modality that is workable and minimally invasive.

Some of the critical clinical challenges encountered in the treatment of adult patients with deep overbite and worn dentition include correction of deep overbite, establishment of an appropriate occlusal vertical dimension (OVD), and maintenance of long-term occlusal stability. Although Angle's Class II division 2-associated deep anterior overbite is common in orthodontic treatment, simple prosthodontic treatment with great improvement of deep anterior overbite and worn dentition is infrequently reported. A 51-year-old man with Class II Division 2 malocclusion presented with hypo-divergent facial pattern, reduced lower facial height, and protuberant lips.

Objective: To report and compare the survival of minimally invasive direct and indirect restorations of different materials for restoring the worn dentition.
Material And Methods: A systematic search was conducted in six databases: MEDLINE, Web of Science, Scopus, CENTRAL, VHL, and EMBASE. The eligibility criteria of this systematic review used the PICO framework to address the following research question: "In dentate patients with a worn dentition (P), does rehabilitating their lost tooth structure with indirect restorations (I) or direct (C) effect the survival and success of treatment (O)?".

Article Synopsis
- The article discusses a clinical case involving a 44-year-old woman suffering from erosive tooth wear due to bulimia and bruxism, focusing on restoring her vertical dimension of occlusion (VDO) using minimally invasive methods.
- After a period of therapy with a Michigan splint, the patient required full mouth prosthetic rehabilitation, leading to the decision to slightly increase her VDO by 1 mm.
- The treatment included creating thin lithium disilicate ceramic restorations for her teeth, demonstrating that effective and aesthetic restoration can be achieved with minimal invasiveness.

The mammalian adult dentition is a non-renewable resource. Tooth attrition and disease must be accommodated by individuals using behavioral, physiological, and/or musculoskeletal shifts to minimize impact on masticatory performance. From a biomechanical perspective, the musculoskeletal system becomes less efficient at producing bite force for a given amount of muscle input force over an individual's life, because tooth-food contact area increases as cusps wear.

Objective: Ultrastructural analyses showed that during erosion under oral cavity conditions, dentin is infiltrated by a substrate morphologically similar to salivary proteins. This in-situ study aimed to investigate the presence of salivary proteins in demineralized dentin.
Methods: Bovine dentin specimens were attached to individual maxillary splints (n = 1 per subject and condition) and worn intraorally by four subjects for 1 min.
