The purpose of this study was to evaluate the dentoskeletal
effects of Modified Maxillary Splint with Headgear in growing
Class II division 1 cases. Sixteen female patients were selected for
this study. The mean age of the patients was 10 years, 1 month.
All patients were treated by Modified Maxillary Splint with
Headgear for an average of 11 months .The cephalometric radiographs
and the study models were analyzed and the collected data were
subjected to statistical analysis. Statistical paired T test was done
to determine the significant difference between the pretreatment
and posttreatment measurements. The Modified Maxillary Splint
with Headgear had skeletal and dental effects. The forward
maxillary growth was restrained however, the mandibular growth
was stimulated. The maxillomandibular relationship was improved. In
addition, while the lower incisors showed a noticeable anterior
movement and proclination. The overjet was significantly
improved. Conclusion: The Modified Maxillary Splint with
Headgear was effective in treatment of growing Class II division 1
patients. The appliance produced skeletal and dental effects.
