Matrix-Guided Composite Resin for Direct Diastema Closure: A Clinical Technique Report.

Area of Science:

• Dentistry
• Restorative Dentistry
• Esthetic Dentistry

Background:

• Increasing demand for esthetic dental procedures, especially among younger demographics.
• Diastema, or gaps between anterior teeth, is a common esthetic concern.
• Existing treatments like orthodontics or porcelain veneers can be invasive.

Purpose of the Study:

• To introduce and evaluate a new, less invasive method for diastema closure.
• To present a case report detailing the application of the putty matrix diastema closure (PMDC) method.
• To demonstrate the efficacy of the PMDC technique in achieving esthetic and functional improvements.

Main Methods:

• Utilized a custom silicone putty index for precise application.
• Employed an ultrathin metal matrix band to guide composite placement.
• Performed progressive composite repair to close the diastema.
• Applied the putty matrix diastema closure (PMDC) method in a clinical case.

Main Results:

• Successfully closed the diastema between the patient's upper right central and lateral incisors.
• Achieved superior esthetic and functional outcomes.
• Conserved significant natural tooth structure.
• Avoided the need for more invasive treatments such as orthodontics or porcelain veneers.

Conclusions:

• The putty matrix diastema closure (PMDC) method is an effective and conservative approach for treating diastema.
• This technique offers a viable alternative to more invasive esthetic dental procedures.
• The PMDC method successfully restores both esthetics and function while preserving tooth structure.
