Assessing the width relationship between the upper and lower teeth is frequently neglected during orthodontic diagnosis and planning, especially when tooth size discrepancies are not immediately obvious. Evaluating tooth size relationships across the jaws supports early detection of disproportions, enabling definitive treatment plans that bring together orthodontic and restorative dental care. A clinical case involved a 16-year-old female patient presenting with persistent gaps in her upper front teeth after undergoing fixed orthodontic treatment for two years and eight months without notable improvement. Her dental history showed an initial diagnosis of Angle's class I malocclusion with bimaxillary protrusion, treated using extractions of the first premolars. Examination revealed multiple spaces and a reduced anterior Bolton's ratio. A satisfactory bite and alignment were successfully achieved by combining corrective orthodontic movements with restorative crown build-up procedures.
Orthodontic treatment can fail or stall if underlying mismatches in tooth size between the upper and lower jaws are not identified early. Demonstrating that integrated care between orthodontists and restorative dentists can resolve persistent dental spacing helps clinicians avoid prolonged, ineffective treatments and achieve better aesthetic and functional outcomes for patients.
This work describes an applied clinical management approach using standard orthodontic adjustments and restorative crown build-ups. Dental practitioners and orthodontic clinics can directly apply this interdisciplinary treatment protocol in everyday clinical practice. However, the abstract describes a clinical case report rather than a commercial product or proprietary technology, and it does not indicate a commercialisation pathway.

The assessment of intermaxillary teeth width relationship is often overlooked during diagnosis and treatment planning of orthodontic patients. This is particularly true for individuals with no obvious teeth size discrepancy. Inter maxillary teeth size assessment is important for early detection of teeth size disproportion between upper and lower jaw. This allows formulation of the definitive treatment planning which may involve both restorative and orthodontic specialists. The current work is reporting a case of 16 years old female patient who complained of multiple spaces on the upper front teeth following braces treatment. The patient had been on fixed orthodontic treatment for 2 years and 8 months without any significant improvement. Past treatment history revealed an initial diagnosis of Angle’s class I malocclusion with bimaxillary protrusion and lip incompetence, which was treated by fixed orthodontic treatment with extraction first pre molars on both jaws. Examination of the patient revealed multiple spaces on third sextant with reduced Bolton’s anterior ratio. In this case, a satisfactory occlusion was achieved by both orthodontic tooth movements and crown build up.
