A person’s unique bite cannot cause periodontal disease; however, it can make periodontal disease worse. In this regard the doctors may suggest isolated or comprehensive bite therapy.
A bite is considered to be healthy when all or most of the teeth are present and not damaged by normal daily usage. It is destructive when teeth show wear, looseness or when TMJ (jaw joint) damage is seen. Bite therapy helps restore a bite that can function without damage and destruction. The therapy may include:
- Reshaping the biting surfaces of the teeth to help eliminate spots of excessive pressure where the teeth are brought into contact. This is done by carefully distributing bite pressures evenly across all of the teeth.
- Bite splint therapy with a custom-fitted and adjusted bite guard is used to keep the teeth apart and promote more relaxed joints and muscles.
- Orthodontic consultation and therapy (braces) to reposition mal-aligned or drifted teeth.
- Replacement of old, worn out, or damaged fillings.
- Reconstruction of badly worn and damaged teeth.
The bitewing view is taken to visualize the crowns of the posterior teeth and the height of the alveolar bone and it’s relation to the cementoenamel junctions, which are the demarcation lines on the teeth which separate tooth crown from tooth root. Routine bitewing radiographs are commonly used to examine for interdental caries and recurrent caries under existing restorations. When there is extensive bone loss, the films may be situated with their longer dimension in the vertical axis so as to better visualize their levels in relation to the teeth. Because bitewing views are taken from a more or less perpendicular angle to the buccal surface of the teeth, they more accurately exhibit the bone levels than do periapical views. Bitewings of the anterior teeth are not routinely taken.
The name bitewing refers to a little tab of paper or plastic situated in the center of the X-ray film, which when bitten on, allows the film to hover so that it captures an even amount maxillary and mandibular information.
The occlusal view reveals the skeletal or pathological anatomy of either the floor of the mouth or the palate. The occlusal film, which is about three to four times the size of the film used to take a periapical or bitewing, is inserted into the mouth so as to entirely separate the maxillary and mandibular teeth, and the film is exposed either from under the chin or angled down from the top of the nose. Sometimes, it is placed in the inside of the cheek to confirm the presence of a sialolith(salivary stone) in Stenson's duct, which carries saliva from the parotid gland. The occlusal view is not included in the standard full mouth series.
- Anterior oblique occlusal mandible – 45°
1) Periapical status of lower incisor teeth for patients who cannot tolerate periapical radiographs.
2) Assess the size of lesions such as cyst or tumours at anterior area of mandible.
- Lateral oblique occlusal mandible – 450
1) Detection of any sialoliths in submandibular salivary glands
2) Used to demonstrate unerupted lower 8’s
3) Assess the size of lesions such as cyst or tumors in the posterior of body and angle of mandible
