| Research Abstract |
For newborn patients with the cleft lip and palate, who received the lip-plasty in an early stage, Hotz's plates applied to enable to feed milk normally as normal babies do.
The results were as follows :
(1) The palatal plates were so effective for increasing milk intake that feeding quantity and time became normal as early as from 5 to 6 months after birth.
(2) The caries incidence rate of 3-year-old patients was 42.1% and df tooth rate 2.1, which were the same rates as these of normal children living in the same area.
(3) The dental arch width and length in the primary dentition of the patients without congenital missing were as the same as these of normal children. In a congenital missing group, the dental arch width and length were larger than these of the patients without using palatal plates.
(4) With regard to the craniofacial growth, undergrowth of the maxilla, severe Class lll cases and dolico types were not found in the stage of the primary dentition.
(5) In the cases using palatal plates, no palatal pronunciation was produced.
(6) The palatal plates were very effective for cleft lip and palate patients to gain normal oral function.
