About
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.
Full description
Skeletal maxillary constriction is one of the common orthodontic problems of all ages, which could be unilateral or bilateral. If it is neglected and not treated, it may result in later orthodontic problems such as skeletal deviation of the lower jaw. The current study aims to use two types of expanders to treat skeletal maxillary constriction in adolescents aged between 12 and 16 years. The study sample will include 52 patients who will be equally divided into two groups: the slow and the rapid maxillary expansion groups. Patients will be asked to answer a questionnaire within five assessment times during the expansion procedure. The questionnaire will contain four questions: 1) What is the degree of discomfort/pain? 2) What is the degree of mastication difficulties? 3) What is the degree of swallowing difficulties? 4) What is the degree of any sense of pressure in soft tissue?
