The lesions are harmless; no treatment is indicated beyond reassurance unless the person requests it. The most common and simple treatment is the construction of a specially made acrylic prosthesis that covers the biting surfaces of the teeth and protects the cheek, tongue, and labial mucosa (an occlusal splint). This is either employed in the ...
Bruxism may cause a variety of signs and symptoms, including: View from above of an anterior (front) tooth showing severe tooth wear which has exposed the dentin layer (normally covered by enamel). The pulp chamber is visible through the overlying dentin. Tertiary dentin will have been laid down by the pulp in response to the loss of tooth ...
When trauma, disease or dental treatment alters occlusion by changing the biting surface of any of the teeth, the teeth will come together differently, and their occlusion will change. [2] When that change has a negative effect on how the teeth occlude, this may cause tenderness, pain, and damage to or movement of the teeth.
Therefore, it is important to understand these tooth wear processes and their interactions to determine causes of tooth surface loss. [8] Demineralization of the tooth surface due to acids can cause occlusal erosion as well as attrition. Wedge-shaped cervical lesions are commonly found in association with occlusal erosion and attrition. [9]
Anterior open bite resulted from tongue thrusting in a 24 y.o. patient. Anterior upper teeth are not touching their counterpart. Anterior open bite (AOB) is defined as a condition in which there is no contact and no vertical overlap of the lower incisor crown with the upper incisor crown when the mandible is in full occlusion. [19]
An open bite malocclusion is when the upper teeth don't overlap the lower teeth. When this malocclusion occurs at the front teeth it is known as anterior open bite. An open bite is difficult to treat due to multifactorial causes, with relapse being a major concern. This is particularly so for an anterior open bite. [58]
Minimal removal of tooth substance is required to create the interocclusal space; therefore, the technique involves limited destruction (this is particularly important on the palatal surfaces of anterior teeth where substantial wear may have occurred. This may be due to conditions causing intrinsic wear, such as bulimia and acid reflux.
This effect is greatest in the anterior (front) teeth and can be seen from around age 4 – 5 years. [6] This spacing is important as it allows space for the permanent (adult) teeth to erupt into the correct occlusion, and without this spacing there is likely to be crowding of the permanent dentition.
