The condition may reflect a forward skeletal position or growth of the maxilla, proclination of the upper incisors, or both mechanisms together. Separating these contributors helps explain why two patients can show similar forward projection but require different management. The distinction also links dental records and cephalometric imaging to individualized treatment planning.
An increased overjet can arise when the upper front teeth sit excessively forward relative to the lower teeth, when the maxilla is positioned forward, or when both occur. This relationship connects tooth position and jaw position to bite function. Facial examination adds another dimension by showing how the underlying discrepancy affects profile and facial balance.
Skeletal and dental findings should not be interpreted in isolation. Facial and intraoral examination describes appearance and occlusion, while dental records and cephalometric imaging help characterize the underlying relationship. Combining these sources supports a more accurate diagnosis, particularly when forward jaw position and upper-incisor proclination contribute together rather than separately.
Clinical assessment begins with facial and intraoral examination, then incorporates dental records and cephalometric imaging. These sources provide complementary information: direct appearance and occlusion findings are considered alongside documented dental relationships and image-based skeletal assessment. Together, they help clinicians determine the contributing pattern and develop an individualized plan rather than relying on one observation.
Treatment selection depends on whether the main problem involves dental positioning, skeletal growth, or a combination. In patients who are still developing, growth modification may be included. Orthodontic tooth movement can address dental relationships, while severe skeletal discrepancies may require a different approach. Identifying the dominant component helps align treatment with the patient’s developmental context.
Orthognathic surgery becomes relevant when the discrepancy is severe and primarily skeletal, whereas orthodontic tooth movement is suited to correcting dental positioning. For patients undergoing development, growth modification may form part of care. These options are not interchangeable; their selection reflects the balance between skeletal involvement, dental involvement, developmental status, and severity.
