NCT05248087

Brief Summary

Maxillary expansion is associated with varying degrees of pain and functional impairments. The current study aims to compare rapid maxillary expansion using a McNamara-type (bonded) appliance and slow maxillary expansion using a removable palatal expansion appliance concerning patient-centered outcomes. Those outcomes will include pain and discomfort, mastication difficulties, swallowing difficulties, and pressure on the soft tissues.

Outcome Measures

Primary Outcomes (4)

  • Change in the levels of discomfort or pain

    The degree of pain and discomfort that patients feel will be determined using their answers to the following question (question 01): 'What is the degree of discomfort/pain?' The Visual Analogue Scale (VAS) will be adopted to measure the degree of discomfort/pain.

    T1: after 24 hours; T2: on the 7th day; T3: on the 15th day; T4: after 1 month; T5: after 4 months

  • Change in the levels of mastication difficulties

    The degree of mastication difficulties that patients feel will be determined using their answers to the following question (question 02): 'What is the degree of mastication difficulties?' The Visual Analogue Scale (VAS) will be adopted to measure the degree of mastication difficulties.

    T1: after 24 hours; T2: on the 7th day; T3: on the 15th day; T4: after 1 month; T5: after 4 months

  • Change in the levels of swallowing difficulties

    The degree of swallowing difficulties that patients feel will be determined using their answers to the following question (question 03): ' What is the degree of swallowing difficulties?' The Visual Analogue Scale (VAS) will be adopted to measure the degree of swallowing difficulties.

    T1: after 24 hours; T2: on the 7th day; T3: on the 15th day; T4: after 1 month; T5: after 4 months

  • Change in the levels of sensation of pressure on soft tissue

    The degree of any sense of pressure in soft tissue that patients feel will be determined using their answers to the following question (question 04): ' What is the degree of any sense of pressure in soft tissue? ' The Visual Analogue Scale (VAS) will be adopted to measure the degree of any sense of pressure in soft tissue.

    T1: after 24 hours; T2: on the 7th day; T3: on the 15th day; T4: after 1 month; T5: after 4 months

Study Arms (2)

The rapid maxillary expansion

EXPERIMENTAL

The rapid maxillary expansion will be applied using a McNamara-type (bonded) appliance.

Device: The bonded McNamara-type appliance

The slow maxillary expansion

ACTIVE COMPARATOR

The slow maxillary expansion will be applied using a removable palatal expansion appliance.

Device: The removable palatal expansion appliance

Interventions

The patient will be asked to expand twice a day until obtaining an overcorrection of 2-3 mm. Then the expander will be kept in place for three months as a retention period.

The rapid maxillary expansion

The slow maxillary expansion will be applied using a removable palatal expansion appliance with a midline screw. The patient will be asked to expand twice a week until obtaining an overcorrection of 2-3 mm.

The slow maxillary expansion
