Purpose:
Prosthetic rehabilitation with stud structure to sectional complete denture for a patient with microstomia was done and the treatment result was evaluated.
Methods:
A sectional impression tray technique was used. And a custom-made palatal hinge mechanism with stud structure on the left and right side of the upper complete denture along the middle line were also designed and fabricated. Half metal abutment was fabricated on the left and right side of the denture on the position of the upper central incisor, and a PFM was made according to the metal abutment. After the sectional upper complete denture was inserted, the PFM was set to connect the sectional denture as a whole and provide stability.
Results:
The sectional upper complete denture was successfully and easily inserted and provided adequate function in the patient's mouth.
Conclusions:
Application of stud structure to sectional upper complete denture for patient with microstomia is feasible.
