What is incisal wear?
Incisal and occlusal tooth wear and wear of some prosthodontic materials. An epidemiological and clinical study. Swed Dent J Suppl. 1989;65:1-62.
What is physiological tooth wear?
The physiological wear of teeth is probably an age-related phenomenon. As the teeth continue to function and be challenged by erosive, attritive and abrasive factors, there will be change to the surfaces of teeth. This is most commonly seen on the incisal edges of the upper and lower incisors.
What is normal tooth wear?
What is the normal amount of wear? As we age, it is perfectly normal to have a certain amount of wear occur on our teeth. After the age of thirty, it is considered normal to lose about one millimeter of length of the upper front teeth, due to normal wear, for each decade of life.
What causes dental wear?
Tooth wear is predominantly the result of a combination of three processes; attrition, abrasion and erosion. These forms of tooth wear can further lead to a condition known as abfraction, where by tooth tissue is ‘fractured’ due to stress lesions caused by extrinsic forces on the enamel.
How do you treat incisal wear?
Bonded porcelain veneers have been used to treat incisal wear. Adhesive cast metal restorations have also been used to replace missing tooth structure. In cases where the occlusion is severely altered by attrition, the only treatment choice may be a reconstruction with crowns and bridges.
How do you fix attrition teeth?
Depending on the cause of dental attrition, there are various treatment options. Most commonly, dental attrition treatment will involve a combination of orthodontic treatment to fix tooth alignment (e.g. Invisalign), dental restorations to fix damaged teeth, and treatment for bruxism (e.g. wearing a night guard).
What is Dahl appliance?
Abstract. The Dahl appliance was described nearly 30 years ago. This removable metal bite platform was used to create inter-occlusal space, in a localised part of the mouth, to facilitate the placement of restorations on worn anterior teeth. The Dahl concept is traditionally associated with the management of worn teeth …
Is tooth wear reversible?
In the early stages, in which we believe the impact is reversible, dietary or gastric acids cause a partial demineralisation of the enamel. Provided normal levels of saliva and acid clearance the impact is unlikely to lead to tissue loss.
What are the 3 main types of tooth wear?
There are three types of tooth wear: abrasion, attrition and erosion. It is sometimes difficult to determine the type of tooth wear present because different types often occur together. Abrasion: Physical wear of the teeth caused by something other than tooth to tooth contact eg.
How do you restore attrition teeth?
What does excessive wear on the incisal edge mean?
Attrition of tooth structure accompanied by continuous eruption, is a normal phenomenon, but cratering or cupping of incisal edges with exposed dentin represents excessive wear. This can be detrimental to a patient as seen in Figs. 1 and 2. Excessive wear areas are easily spotted on lower incisors (Fig. 3).
Why do I need a nightguard on my incisal edges?
This would protect them from chipping and prevent further erosion of the dentin. In either case, a nightguard was part of the plan. It was made clear to the patient that edge reinforcement would address the results of his bruxism, like the worn and chipped edges, but not the causes.
Why are there troughs on the incisal edge?
Conservative troughs were created in the upper incisal edge indentations for several reasons. Prepared enamel would offer better bonding than unprepared enamel and having a resistance form for the restorations would provide better long-term retention.
