Area of Science:

  • Dentistry
  • Prosthodontics
  • Dental Materials

Background:

  • Microstomia presents challenges in obtaining accurate impressions for edentulous patients.
  • Conventional impression techniques may be difficult to adapt for patients with limited mouth opening.

Purpose of the Study:

  • To describe a preliminary impression technique for edentulous patients with microstomia.
  • To facilitate the fabrication of diagnostic casts in challenging clinical situations.

Main Methods:

  • Modification of stock impression trays to create sectional trays.
  • Taking sectional impressions of the maxillary arch (left and right sides).
  • Utilizing a two-stage pour technique with the diagnostic cast positioned in the second impression.

Main Results:

  • The described technique allows for the successful capture of preliminary impressions in patients with microstomia.
  • Accurate diagnostic casts can be fabricated using this modified sectional impression method.

Conclusions:

  • This preliminary impression technique offers a viable solution for edentulous patients with microstomia.
  • The method aids in the creation of essential diagnostic casts for prosthodontic treatment planning.
