Attrition may explain some of the alterations that occur after months or years of rehabilitation treatment, since it causes changes in shape and mesiodistal and occlusal-apical size of dental crowns, changing their position and relationship with dental implants. Dental attrition may: 1) represent a sign of occlusal maladjustment; 2) suggest the existence of parafunctional habits such as clenching and bruxism; 3) reduce the circumference of the dental arch because the proximal dental contact points turn into wear facets over the years; 4) age the mouth due to some morphological details that vary with age, namely: absence of serration caused by smoothing of the incisal edge until the dentin appears and a dark yellow line can be seen between the buccal and the incisal enamel of incisors and canines; 5) worsen aging caused by dental crowding; 6) aggravate aging by causing loss of facial vertical dimension; 7) be associated with diastemata between osseointegrated implants and natural teeth a few years after rehabilitation treatment is finished.
