Case Diagnostic
Report 41892

A complete clinical review of one alignment case—from initial findings and diagnostic imaging to treatment simulation.

Patient: Male · 27 years
Chief concern: Alignment
Doctor: Dr. House
Report date: May 29, 2026

CHIEF CONCERN & PROBLEM LIST

The case begins with a clear clinical baseline.

Treatment objective: align. Records include intraoral photographs, facial photographs, digital models, a lateral cephalogram and a panoramic radiograph.

Profile type

Straight profile

Skeletal findings

Skeletal Class I

Low-angle pattern

Dental findings

Left Angle Class II
Right Angle Class II
Maxillary: 2.25 mm spacing
Mandibular: 0.68 mm, normal
Mandibular arch 4–4 is excessively wide
Proclined maxillary central incisors

Oral health

Insufficient eruption space: 13, 15, 23
Potential impaction: 18, 28, 38, 48

IOTN and PAR indices indicate a high treatment need and severe initial malocclusion. These data provide an objective baseline for treatment selection and outcome evaluation.

SKELETAL, GROWTH & AIRWAY ANALYSIS

Measurements are read together—not as isolated charts.

Cephalometric conclusion

Skeletal Class I, low angle, proclined lower incisors.

PANORAMIC & INTRAORAL RECORDS

Clinical findings remain attached to their evidence.

Insufficient eruption space

Teeth 13, 15 and 23 have limited space in their respective regions, restricting normal eruption.

Potential impaction

Based on tooth position, eruption path and surrounding structures, teeth 18, 28, 38 and 48 present potential impaction risk.
