Summary

Orthodontic build-ups are made by composite/resin material bonded to the palatal or occlusal surfaces of teeth (usually molars or incisors). Their primary purpose is to prevent heavy contact of the upper teeth with lower fixed appliances in patients with overbite reduction to avoid brackets detachment. These appliances disarticulate the posterior teeth, deprogram the masticatory muscles and allow for eruption, extrusion, and uprighting of the posterior teeth. Build-ups are usually placed in the first months of the fixed orthodontic treatment and contribute to increasing the perception of pain. In the orthodontic daily practice, the pain is the most frequent symptom during treatment and is the one that most frightens/worries the patients. Literature shows that fear of pain is one of the primary reasons that patients fail to seek orthodontic care. Pain has a negative effect on patients' compliance, oral hygiene, and missed appointments. Its effects on patients' daily lives is a major reason for discontinuance of orthodontic treatment. In the literature the prevention of pain and management of orthodontic builds-ups is a poorly analyzed topic, despite being a daily problem in orthodontic clinical practice. So, the aim of the present study is to investigate and analyze the perception of pain and function impairment with different type of build-ups (anterior or posterior) to identify an efficient clinical management protocol and an effective pain and discomfort prevention strategy.

Conditions

• Malocclusion
• Deep Bite

Interventions

Type	Name	Description
DEVICE	orthodontic - Anterior resin builds-ups	After lower brackets placement, resin builds-ups are added on the palatal aspect of the upper central incisors. Both central incisors are customarily bonded to broadly distribute the occlusal forces. Builds-ups are removed when the overbite was considered adequate to prevent lower brackets detachment.
DEVICE	orthodontic - Posterior resin builds-ups	After lower brackets placement, resin builds-ups are added on the supporting cusps of first or second upper/lower molars. Builds-ups are removed when the overbite was considered adequate to prevent lower brackets detachment.
