Intrusion and uprighting teeth for fixed prosthesis with temporary anchorage device

Area of Science:

• Dentistry
• Orthodontics
• Prosthodontics

Background:

• The mandibular first permanent molar erupts early and is susceptible to decay.
• Premature loss of this tooth can lead to significant malocclusion.
• Consequences include adjacent tooth tipping and opposing tooth extrusion.

Observation:

• Extraction of the mandibular first permanent molar often results in space closure.
• Posterior occlusion collapse is a common complication.
• Adjacent teeth tip into the extraction site, and opposing teeth extrude.

Findings:

• This article presents a step-by-step procedure for correcting malocclusion post-extraction.
• Techniques for uprighting tipped teeth and intruding extruded teeth are described.
• The methods are demonstrated on acrylic models and then applied to patients.

Implications:

• Effective management of extraction spaces is crucial for maintaining dental arch integrity.
• Restoring proper occlusion prevents further complications and facilitates prosthetic rehabilitation.
• This approach aids in preserving the functional and aesthetic outcomes of dental treatment.
