    Journal: Head Neck; 1998 Jan; 20(1):38-51. PubMed ID: 9464951.
    Abstract:
    BACKGROUND: Mandibular reconstruction with functional dental rehabilitation using a free tissue transfer bone flap as the substrate for osseointegrated implant-borne or implant-retained dental prostheses is well described. Similar use of these techniques in maxillary dental rehabilitation is less frequent and has received less attention in the literature. However, in selected cases of extensive composite defects of the maxilla, free tissue transfer reconstruction of the maxillary arch and the use of implant-borne or implant-retained dental prostheses is the only satisfactory method of achieving functional dental rehabilitation. METHODS: Three cases of maxillary reconstruction and dental rehabilitation using free tissue transfer with implant-borne or implant-retained prostheses are presented. Patient selection, reconstructive technique, and the biomechanical considerations in maxillary dental rehabilitation of large palatomaxillary defects are presented. RESULTS: The patients in this report were restored to full maxillary dental functioning. One implant of 17 implants placed in free flap bone was lost due to failure of osseointegration; 94% of the implants placed are stable an average of 18 months after dental rehabilitation was complete. CONCLUSIONS: In selected patients with extensive palatomaxillary defects due to ablative surgery or trauma, the use of free tissue transfer and osseointegrated implant-borne or implant-retained dentures may be the only method possible to restore maxillary dental function. Dental rehabilitation of large maxillary defects presents a number of biomechanical challenges which must be clearly understood and overcome to achieve a long-term, functional dental rehabilitation.
