Descrição
Inclusion Criteria:
- Patients who have undergone fixed orthodontic treatment at the Department of Orthodontics, Faculty of Dentistry, Marmara University, and whose treatment is nearing completion
- Patients whose treatment duration is between 2 and 3 years
- Patients with healthy periodontal tissue (plaque index and gingival index <1; bleeding on probing <10 per cent; no clinical attachment loss)
- Patients aged between 18 and 35
- Systemically healthy individuals
- Patients with deep bite for whom Nitinol wire retainers, manufactured using CAD/CAM technology and capable of being fitted without occlusal contact due to their adaptability to the occlusion, have been applied
- Patients for whom impressions cannot be taken to fabricate a retainer
- Patients without deep bite or a gag reflex who have had a standard retainer fitted
Exclusion Criteria:
- Patients who have undergone orthodontic treatment at another clinic
- Patients whose treatment lasted longer than 3 years or less than 2 years
- Patients with a cleft lip and palate or a related syndrome
- Patients with caries or dental prostheses on the teeth where the retainer is to be bonded
- Smokers
- Individuals with missing anterior teeth
- Individuals taking systemic medication that affects the immune system or may affect periodontal health (e.g. steroids)
- Pregnant or breastfeeding women

Tooth mobility
Prazo: From enrollment to the end of treatment at 6 months
|
Tooth mobility will be assessed using the Periotest device.
The device will be applied to the buccal surface of the tooth, and the Periotest value (PTV) will be recorded according to the manufacturer's instructions.
Higher PTV values indicate greater tooth mobility.
Measurements will be recorded as Periotest values (PTV).

Little irregularity
Prazo: From enrollment to the end of treatment at 6 months
|
Anterior dental irregularity will be assessed using Little's Irregularity Index, measured as the sum of the five linear displacements between the anatomic contact points of the mandibular anterior teeth, in millimeters (mm).
This assessment will be performed on digital intraoral models by using Orthomodel (Orthomodel, İstanbul, Türkiye) software.
|
From enrollment to the end of treatment at 6 months
|
|
Arch length
Prazo: From enrollment to the end of treatment at 6 months
|
Dental arch length will be assessed by measuring the linear distance from the midpoint between the central incisors to a line connecting the distal surfaces of the first permanent molars, in millimeters (mm).
This assessment will be performed on digital intraoral models by using Orthomodel (Orthomodel, İstanbul, Türkiye) software.
