What Is Overjet And How Can It Be Treated
The term overjet describes how far the top front teeth stick out horizontally compared to the bottom teeth — a frequent orthodontic condition where the top incisors jut forward excessively beyond the lower ones. While a minor amount of overjet is natural and functional, severe overjet can cause functional problems, make the front teeth more vulnerable, create challenges with biting or chewing, and even undermine self-confidence due to appearance-related anxiety.
Overjet can stem from a variety of causes. Jaw structure is commonly inherited, meaning the natural positioning of the maxilla and mandible can be passed down through families. Additional triggers involve extended non-nutritive sucking, extended bottle or pacifier dependency, which can force the upper teeth forward while driving the bottom teeth inward. Obstructed airways can also alter facial growth patterns. In some instances, absent mandibular dentition or insufficient mandibular growth may contribute significantly to the malocclusion.
Treatment strategies for overjet depends on the degree of malocclusion and the patient’s age. In children and teenagers, timely orthodontic treatment is highly recommended. Braces and clear aligners are frequently prescribed to reposition the teeth. When jaw growth discrepancy is involved, orthopedic appliances such as headgear or rapid maxillary expanders may be recommended to stimulate forward growth of the lower jaw or moderate upper arch expansion.
For adults with severe overjet, braces or aligners only may be insufficient to achieve optimal results. In such cases, jaw repositioning surgery may be necessary to properly realign the jaws. This procedure is typically preceded and followed by braces or aligners to guarantee post-surgical bite accuracy.
Treatment duration varies widely, depending on the treatment plan. Slight protrusion can often be resolved in 12 to 18 months, while complex cases may require 24–36 months. Scheduled monitoring appointments are vital to track progress and maintain treatment efficacy.
If excessive protrusion is detected, 東京 部分矯正 it is crucial to consult an orthodontist. An initial consultation, ideally before permanent teeth fully erupt, allows the orthodontist to detect potential issues early and simplify correction. Treatment doesn’t just enhance appearance — it also boosts oral health by enhancing chewing efficiency.
Maintaining excellent oral hygiene during treatment is essential. Fixed or removable hardware can make cleaning difficult, so consistent brushing and flossing, along with professional prophylaxis, are critical for avoiding cavities and gum disease. Post-correction phase, wearing retainers as instructed is absolutely vital to prevent relapse.
Understanding overjet and its treatment empowers patients and families to choose the right path. With appropriate intervention, the vast majority of overjet cases can be successfully corrected, resulting in improved function, greater comfort, and sustained self-esteem.
