A 25-year-old female patient presented with multiple orthodontic concerns, including a constricted maxillary arch, generalized spacing in the mandibular arch, protrusion of the upper anterior teeth, and generalized spacing throughout the dentition. The patient also had a previously extracted upper left first permanent molar.
Initial Diagnosis:
Skeletal: Constriction of the maxillary arch, contributing to transverse discrepancy.
Dental: Proclination and protrusion of the maxillary anterior segment with generalized spacing; spacing also noted in the mandibular arch.
Other: Upper left first permanent molar missing, which affected the occlusal stability and required space management.
Treatment Objectives:
Expand the maxillary arch to correct the transverse constriction and create sufficient space for alignment.
Achieve proper alignment and leveling of both arches.
Close generalized spacing in both arches to improve esthetics and function.
Correct the upper incisor protrusion and establish proper incisor inclination and overjet/overbite relationships.
Manage the edentulous space of the missing upper left first permanent molar appropriately.
Achieve a stable, functional, and esthetic occlusion with good interarch coordination.
Treatment Plan:
The comprehensive treatment plan consisted of two major phases:
Phase I: Orthopedic expansion of the maxillary arch using an appropriate maxillary expander to correct the constriction and create space for proper tooth alignment.
Phase II: Comprehensive fixed orthodontic treatment using pre-adjusted edgewise appliances (brackets and archwires) to align and level both arches, close residual spaces, retract the upper anterior teeth, and coordinate the arches. Anchorage was planned and reinforced as needed to control unwanted tooth movement during space closure and retraction.
Treatment Progress and Outcome:
The maxillary expansion was successfully achieved, resulting in improved transverse dimension and arch form. Fixed appliances facilitated the alignment of both arches, closure of generalized spaces, and retraction of the protrusive upper incisors. Careful attention was given to the edentulous upper left molar site, maintaining appropriate space or preparing the area for future prosthetic rehabilitation if indicated.
The final occlusion demonstrated well-aligned arches with proper overjet and overbite, improved arch form, and a harmonious facial profile. The patient achieved significant esthetic and functional improvements, with the treatment objectives fully accomplished. Long-term retention was planned to maintain the achieved results.
