[The effect of artificial bone implantation in cleft palate on the development of maxilla].

OBJECTIVE

To research the influence of palate bone implantation to the growth of maxilla in three dimensional direction.

METHODS

40 patients of congenital cleft palate type II with palate board damage were stochastically divide into the comparison group and bone planted group. In bone planted group, HA-Bone cement was used to repair palate tabular damage. All patients are 16 full year old, cephalometric radiograph and tooth cast model were measured and contrast analysis was applied.

RESULTS

Planted bone group and the comparison group does not have the significance difference in both the maxilla length and maxilla hightness( P > 0.05); But there was significance difference in the width of post-part of the maxilla (P < 0.05).

CONCLUSIONS

It could promote the growth of maxilla width in use of bone implantation, that advocated the bone repair in the sequence treatment process in cases of the hard palate bone damage.
