Demonstrate the distal surface
of canine crowns and all of the first and second premolar crowns.
2mm Ceka Preci-Sagix attachment were planned on distal surfaces
of 13 and 25.
Primary canine relationship was evaluated and recorded as class 1: the tip of the maxillary primary canine tooth is in the same vertical plane as the distal surface
of the mandibular primary canine; class 2: the tip of the maxillary primary canine tooth is mesial to the distal surface
of the mandibular primary canine; class 3: the tip of maxillary primary canine is distal to the distal surface
of the mandibular primary canine .
distal step (DS)--the distal surface
of the mandibular primary second molar is located in a more distal position relative to the distal surface
of the maxillary primary second molar.
Retromolar space from anterior edge of ramus AER-7 was measured up to the distal surface
of the lower second molar along the occlusal plane.
The distolingual surface is also worn in this specimen and towards the base of the distal surface
there is a well-developed, triangular wear facet.
Ornamentation varies not only in type but also in topography; that is, the proximal and distal ridges and the proximal and distal surfaces
may have ornamentation that varies.
The suggested etiology of the increased rate of impaction is inadequate space in the retromolar area, between the distal surface
of 2nd molar and anterior border of ramus of the mandible.
Intraoral examination revealed a proximal carious lesion involving the distal surface
of tooth 74 and occlusal caries with 75 (Figure 1).
Type B: Remaining obliquely worn cusp of a maxillary tooth overhanging the distal surface
of its functional antagonist.
Alternatively, to facilitate the eruption of the FPM, the distal surface
of the second primary molar can be reduced [Kurol, 2002].
