The bisecting angle technique is an older method for periapical radiography. It can be a useful alternative technique when the ideal receptor placement using the paralleling technique cannot be achieved, for reasons such as anatomical obstacles e.g. tori, shallow palate, shallow floor of mouth, or narrow arch width.

In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...
Another point worthy of note is that the angle of the condyle in medial direction which also affects the direction of force. It is easy to establish the balanced occlusion on an articulator , but other variables come into play the moment the denture is inside the patient's mouth and this further affects the outcome of treatment.
Occlusion, in a dental context, means simply the contact between teeth.More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest.

In dentistry, numerous types of classification schemes have been developed to describe the teeth and gum tissue in a way that categorizes various defects. All of these classification schemes combine to provide the periodontal diagnosis of the aforementioned tissues in their various states of health and disease.
