Sectional impression tray for patients with constricted oral opening

Area of Science:

• Dental prosthetics
• Impression techniques

Background:

• Constricted mouth opening presents challenges for conventional dental impressions.
• Accurate impressions are crucial for fabricating well-fitting dental prostheses.

Purpose of the Study:

• To describe a method for obtaining dental impressions in patients with limited mouth opening.
• To introduce the use of a sectional impression tray for this patient group.

Main Methods:

• Utilized a sectional impression tray that can be assembled intraorally.
• The tray was disassembled within the mouth and reassembled externally for impression completion.

Main Results:

• Successful dental impressions were achieved despite the patients' constricted mouth opening.
• The sectional tray facilitated manipulation in confined intraoral spaces.

Conclusions:

• Sectional impression trays offer a viable solution for patients experiencing limited mouth opening.
• This technique enhances the ability to capture accurate dental impressions in challenging clinical situations.
