Inverted Layering Technique as a Biomimetic Procedure in the Multidisciplinary Resolution of Discolored Teeth: A Case...

Area of Science:

• Dentistry
• Restorative Dentistry
• Esthetic Dentistry

Background:

• Dental darkening of anterior teeth can negatively impact smile esthetics.
• Childhood trauma is a common cause of dental discoloration.
• Conservative treatment options are sought to preserve tooth structure.

Purpose of the Study:

• To describe a novel restorative approach using reverse composite resin application for esthetic resolution of darkened anterior teeth.
• To evaluate the efficacy and viability of this conservative technique.

Main Methods:

• A case report of a 27-year-old female with darkened anterior teeth (11 and 21) due to childhood trauma.
• Periodontal intervention for gingival leveling followed by endodontic treatment.
• Restorative procedure included internal bleaching, pigmented dentin removal, and enamel preservation.
• Composite resin restoration applied using a reverse technique with polyethylene fiber reinforcement.

Main Results:

• The reverse composite resin technique successfully restored the esthetics of darkened anterior teeth.
• The procedure preserved remaining enamel and maintained anterior guidance.
• No painful symptoms or pathological signs were reported post-treatment.
• Successful restorative efficacy was confirmed at the 1-year follow-up.

Conclusions:

• The reverse composite resin application is a viable and conservative alternative for restoring darkened anterior teeth.
• This technique effectively addresses esthetic concerns while preserving natural tooth structure.
• The method offers a minimally invasive solution for dental discoloration.
