Summary
This rare case of missing maxillary molars caused significant jaw imbalance. Orthodontic treatment improved jaw alignment and muscle function.
Area of Science:
- Dentistry
- Orthodontics
- Oral Surgery
Background:
- Congenital absence (agenesis) and impaction of maxillary molars are uncommon dental anomalies.
- The simultaneous occurrence of these conditions in the left maxillary arch is exceptionally rare.
- Such anomalies can lead to severe occlusal disharmony and functional deficits.
Observation:
- A rare case involving the absence of the left first maxillary molar (due to impaction) and the left second maxillary molar (due to agenesis).
- This dental anomaly resulted in significant occlusal imbalance and asymmetrical mandibular movement.
- The patient presented with a retrognathic mandible and altered muscular activity.
Findings:
- A comprehensive gnatologic and functional orthodontic approach was implemented.
- Diagnostic tools including kinesiography and electromyography were utilized to assess mandibular dynamics and muscle function.
- Treatment aimed to correct the occlusal imbalance and improve mandibular posture and muscular activity.
Implications:
- This case highlights the complex management of rare combined dental anomalies.
- Functional orthodontic strategies can effectively address severe occlusal imbalances and associated mandibular dysfunction.
- Utilizing advanced diagnostic tools is crucial for planning and evaluating treatment outcomes in complex orthodontic cases.
