Early interceptive treatment in the primary dentition - a case report

Area of Science:

• Dentistry
• Orthodontics
• Pediatric Dentistry

Background:

• Class II malocclusion, characterized by maxillary and mandibular crowding, posterior crossbite, and increased deep bite, presents complex treatment challenges.
• Early intervention in the mixed dentition stage is crucial for managing complex malocclusions.
• Treatment strategies focusing solely on primary teeth offer a minimally invasive approach.

Observation:

• A modified Haas-type rapid maxillary expansion (RME) appliance anchored to primary canines and second molars was utilized.
• Appliance activation (0.20 mm daily) for 30 days, followed by a 6-month retention period.
• Subsequent use of headgear on primary molars and sequential lower primary tooth slicing to manage arch space.

Findings:

• Successful correction of Class II malocclusion, posterior crossbite, and improved maxillary and mandibular crowding.
• Overjet and overbite were significantly improved without involving permanent teeth.
• Achieved a Class I dental relationship in the permanent dentition.

Implications:

• Treatment focused exclusively on primary teeth can be a viable and effective strategy for correcting complex malocclusions in early mixed dentition.
• This approach may prevent the need for permanent tooth extraction or more invasive procedures.
• Highlights the potential of early, conservative orthodontic interventions in pediatric dental care.
