Abstract
Restorative method of congenital missing or traumatic loss of permanant teeth in children are very complicated. For the most cases, fabrication of porcelain fused metal bridge for a permanant tooth that was lost early in childhood is not the
treatment
of choice, because it involves much reduction of abutment teeth and so llarge pulp chambers can be easily esposed. Rather, temporary removable space maintainer with resin pontic or a restoration method, in which the first molar is banded and
heavy
wires
is soldered and connected to anterior resin tooth, is used.
Nevertheless, disadvantages such as patients discomfort, difficulty in care of appliance, and adverse periodontal effects, still exist.
Since a restoration method that did not involve abutment reduction was introduced in 1970's, etched cast restoration (so called "Maryland bridge") with increased strength and bond strength has been developed. Etched cast restoration has many
advantages
: it is favorable in appearance ; requiring only the slight reduction of abutment teeth lessens possibility of pulp exposure ; and supragingival margin allows maintanance of good gingival health.
In these cases, satisfactory results were obtained from using etched cast restoration for treatment of 13.2-year-old boy with traumatic loss of maxillary left central incisor and 11.3-year-old girl with congenital missing of mandibular left
central
incisor.
