Summary
Early correction of posterior crossbite in primary teeth (7-17% incidence) prevents jaw deviation and TMJ issues. Treatment ensures permanent molars erupt correctly in 84% of cases.
Area of Science:
- Dentistry
- Orthodontics
- Pediatric Dentistry
Background:
- Posterior crossbite affects 7-17% of primary dentition cases.
- Often caused by constricted maxilla, leading to mandibular deviation during occlusion.
- Functional posterior crossbite requires correction to prevent temporomandibular joint (TMJ) issues.
Observation:
- Two clinical cases of posterior crossbite in the primary dentition were diagnosed and managed.
- The study focuses on the diagnosis and treatment of this specific malocclusion.
Findings:
- Correction of functional posterior crossbite in the primary dentition is crucial.
- Early intervention promotes a stable occlusion and healthy TMJ development.
- Treatment success rate shows first permanent molars erupting in a normal transverse relationship in 84% of cases.
Implications:
- Timely treatment of posterior crossbite in primary teeth is essential for optimal dental arch development.
- Establishes a foundation for normal occlusion and reduces the risk of future orthodontic complications.
- Highlights the importance of early diagnosis and management in pediatric dental care.
