Summary

Presurgical infant orthopedics (PSIO) aims to align cleft palate segments before surgery. This study developed a 3D method to quantify maxillary growth in infants with cleft lip and palate treated with passive appliances.

Background:

Presurgical infant orthopedics (PSIO) aims to improve outcomes for infants with cleft lip and palate.
The efficacy of passive appliances in guiding maxillary growth remains incompletely understood.

Purpose of the Study:

To develop and evaluate a 3D digital method for quantifying maxillary growth in infants with cleft lip and palate.
To assess the impact of passive appliances on maxillary development.

Main Methods:

A pilot study involving 5 infants with complete unilateral cleft lip and palate (UCLP).
Sequential digital scans of plaster casts taken from infancy to 12 months.
3D computer reconstruction, segmentation, and superimposition of casts to analyze maxillary growth.

Quantitative analysis of volumetric changes in defined maxillary segments.

Main Results:

The developed 3D method successfully quantifies growth rates in specific maxillary segments.
The study demonstrated the feasibility of visualizing morphological changes over time.
Initial results indicate the potential for objective assessment of PSIO's effects.

Conclusions:

A novel 3D digital analysis procedure enables metric analysis and visualization of maxillary growth in infants with cleft lip and palate.
This method provides a basis for future studies to objectively evaluate presurgical infant orthopedics.
Further research is needed to fully elucidate the growth-modulating effects of passive appliances.
