Mind the gap: A novel technique for space closure - a case report

Area of Science:

• Dentistry
• Orthodontics
• Dental Anomalies

Background:

• Severe hypodontia poses management challenges due to significant dental arch spaces and compromised anchorage.
• Lack of permanent teeth complicates orthodontic treatment planning and execution.

Observation:

• A 14-year-old patient with severe hypodontia presented with a 7-mm midline diastema requiring closure for partial denture provision.
• Initial attempts at space closure using a standard archwire resulted in undesirable incisor crown tipping.

Findings:

• A novel technique utilizing a four-bracket system (two brackets per central incisor) was implemented for diastema closure.
• This system employed dual stainless steel archwires and elastomeric chains, enabling bodily tooth movement and superior anchorage control.
• Excellent root parallelism was achieved during the 7-mm midline diastema closure.

Implications:

• This innovative four-bracket technique offers a viable solution for diastema closure in severe hypodontia cases with limited anchorage.
• It facilitates controlled bodily tooth movement, ensuring optimal root parallelism and aiding in prosthetic rehabilitation.
• The technique enhances treatment predictability and outcomes for patients with complex dental anomalies.
