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 ...
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.

Bennet Angle : the angle of medial movement on NWS condyle relative to the vertical plane Condylar Angle : the angle of downwards movement of the NWS condyle relative to the horizontal plane The working side (WS) condyle (also called the rotating condyle) undergoes an immediate, non-progressive lateral shift.
The offset lies at an angle to the mesio-distal axis of the tooth, and causes the mesial portion of the central groove to be located further buccally than the distal portion. This buccolingual shift correlates with a relative difference in size between the mesial and distal cusps on these teeth - the mesiolingual cusp is larger than the ...
In conclusion, an ideal occlusion is set by various groups based on a hypothetical assumption. While, questioning this concept may be ignorant, criticizing this technique does not mean it does not work on a clinical level. Other studies show that there is another occlusion scheme that can be considered in place of the balanced occlusion. [7] [10]
An Iowa school is catching flak for having no “rizz.”. A teacher in a school district near the Nebraska border is being accused of banning the word short for charisma along with over two dozen ...
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.
Three important angles used in his analysis are: 1. Saddle Angle - Na, S, Ar 2. Articular Angle - S-Ar-Go, 3. Gonial Angle - Ar-Go-Me. In a patient who has a clockwise growth pattern, the sum of 3 angles will be higher than 396 degrees. The ratio of posterior height (S-Go) to Anterior Height (N-Me) is 56% to 44%.
