Here are some images of Impaceted teeth which are very Rare and we do not know whether they are Developmental Disturbances or Impacted Teeth.
Here we can see the crown of an impacted tooth fused with the roots of an erupted tooth. Here we can see that both the teeth are well developed morphologically, the crown and root are well developed. With the crown morphology we can say that the impacted tooth is a 3rd molar the most common impacted tooth.
Here is another angle of view to see the weirdly impacted 3rd Molar placed between the roots of adjacent 2nd Molar, it looks as if the 2nd Molar is holding onto the 3rd molar when it is falling down.
Here we can see a very rare Morphological deformity with the crown at a 90 degree angulation to the long axis of roots.
