Previously, patient satisfaction with orthodontic treatment has been reported at a broad range of 34% to 95% but these values mostly represent satisfaction for tooth alignment or simple satisfaction with treatment results. In keeping with the increased focus on patient satisfaction, many other factors were put into consideration in our study which contributes to the level of total satisfaction as host factors, concerns regarding the treatment, treatment motivation and discomfort during or after treatment. There are also a lack of studies conducted for orthodontic treatment satisfaction using previously validated questionnaires as well as correlation between patient's treatment satisfaction and ABO grading hasn't been sufficiently discussed in the literature, this study aims to address that gap. It would be also beneficial to investigate the frequency of different malocclusions presented in a sample of postorthodontic patients as it will give an insight about the distribution of the different malocclusion treated within the clinic and the degree of success in treating such malocclusions.

Research Procedure in brief:

The following will be done for each participant:

Collection of patients telephone numbers:

Through the orthodontic department patient's database ensuring complete confidentiality. Telephoning the patients for follow ups after orthodontic treatment and asking them to fill in a questionnaire during their visit for explaining our aim for the study.

Personal data chart:

Including name, age, date of birth, mobile number and address. Examination of pretreatment records of the patients included in the sample to detect the type of malocclusion presented initially.

Orthodontic treatment satisfaction questionnaire:

The questionnaire is reviewed by faculty experts to determine whether the items in the questionnaire truly represent the items to be measured.

The translated questionnaire's face validation is led by the expert faculty members who are specialists in both English and Arabic guaranteeing clarity, intelligibility and comprehensiveness of items. This is significant in light of the fact that while performing any questionnaire in another setting, not all of the items may be compatible to Egyptian culture and lifestyles. In addition, a portion of items may not be applicable to specific age groups.

ABO Grading System Study models will be selected from the orthodontic department database. The post-treatment models will be assessed using the MGS of the American Board of Orthodontics.
