Prosthodontic principles in the framework design of maxillary obturator prostheses

Zygoma implant-supported prosthetic rehabilitation after partial maxillectomy using surgical navigation: A clinical report

“…In dentate patients, support, stability and retention of such an obturating removable prosthesis relies on the remaining hard and soft tissues. 11,21,22 The larger the surgical resection, the greater the loss of mucogingival support, which in turn results in increased unfavorable forces acting on the remaining abutment teeth. 12,22,23 Since the advent of osseointegration the combination of implants and prosthetic obturators has proven to be beneficial, especially in the rehabilitation of the edentulous maxillectomy patient.…”

[24][25][26][27] Because of the limited amount of remaining maxillary bone following maxillectomy, implant placement for anchoring a prosthesis has also been performed in more remote sites such as the zygomatic bone.…”

Rehabilitation of apartial maxillectomy patient with silicone relined hollow bulb obturator – Case report

“…Third molar tooth of left side of the maxillary arch was used for retention of the prosthesis through wrought alloy clasp.The weight of prosthesis was often a dislodging factor that has to be considered 3,4 . Weight reduction was cardinal when the obturator prosthesis was suspended without bony or posterior tooth support on the defect side 5 . The weight of the prosthesis can be reduced up to 33% when obturator is fabricated hollow 6 .…”

Rehabilitation of a complete maxillectomy patient: A case report of osteomyelitis of maxilla

“…The larger the surgical resection, the greater the loss of the mucogingival support, which in turn results in increased unfavourable forces acting on the remaining abutment teeth. [11] [13] This clinical report demonstrates, by utilizing the soft tissue defect and soft liners for retention purpose and fabrication of a two piece obturator prosthesis to attain light weight for a patient with complete maxillectomy, secondary to Osteomyelitis.…”
