Overview
Reduced overjet refers to a condition where the upper teeth are positioned significantly behind the lower teeth, often impacting occlusion and aesthetics. This condition may arise from various factors including genetic predisposition, habits, or developmental issues 1.Diagnosis
Clinical Assessment: Evaluation of dental occlusion and alignment 1.
Radiographic Imaging: Use of cephalometric radiographs to assess skeletal and dental relationships 1.
Grading: Typically classified based on severity, though specific grading systems are not detailed in the provided abstracts 1.Management
Orthodontic Treatment: Utilization of appliances such as braces or aligners to correct the overjet 1.
Habit Modification: Addressing habits like thumb sucking or tongue thrusting that contribute to overjet 1.
Surgical Intervention: In severe cases, orthognathic surgery may be considered to correct skeletal discrepancies 1.Special Populations
Pediatrics: Early intervention with habit appliances can prevent progression 1.
Elderly: Focus on functional occlusion and comfort, often requiring conservative orthodontic approaches 1.Key Recommendations
Implement orthodontic interventions early to correct reduced overjet and improve occlusion (Evidence: Moderate 1).
Incorporate habit modification strategies in pediatric patients to prevent worsening of overjet (Evidence: Moderate 1).
Consider orthognathic surgery for severe cases where orthodontic treatment alone is insufficient (Evidence: Expert opinion 1).References
