A diastema (pl.: diastemata, from Greek διάστημα, 'space') is a space or gap between two teeth. Many species of mammals have diastemata as a normal feature, most commonly between the incisors and molars. More colloquially, the condition may be referred to as gap teeth or tooth gap.
Diastema – Space between upper front two teeth; Fenestration of buccal bone [13] Compression of periodontal ligament near posterior teeth; Extrusion of posterior teeth; Increased lingual bone thickness, decreased buccal bone thickness [13] One of the limits of expansion is the zygomatic buttress. It is known that this anatomical bony complex ...
General patterns of dental morphological evolution throughout human evolution include a reduction in facial prognathism, the presence of a Y5 cusp pattern, the formation of a parabolic palate and the loss of the diastema. Human teeth are made of dentin and are covered by enamel in the areas that are exposed. [2]
- The difference between diastema in terms of (human) dentistry is that it refers almost always to a gap between the upper central incisors. In zoology, diastema means a gap between teeth of dissimilar types, i.e. between the molars and the incisors, as occurs in grass-eating animals or rodents.
Midline diastema (spacing in upper teeth) is a common occurrence in the population. [26] An arbitrary number for the spacing between the teeth to consider as midline diastema is a width of 0.5 from a proximal surface of a teeth to the proximal surface of adjacent teeth. [27] Midline diastema usually occur in the upper teeth compared to lower.

Precanine teeth are often replaced by a large diastema in therapsids. [5] [10] Kenomagnathus had both precanine teeth and a diastema, which fills the gap between basal synapsids and therapsids to some extent. It reflects what would have been an ongoing transition, which other stem-mammals with diastemata would also have gone through.
