【Abstract】
Objective: To study the application of Dental Implant Distracter (DID) with fibula in mandibular functional reconstruction.
Materials and Methods: We designed a
new device named DID (Dental Implant Distracter), which including the permanent
dental implant and the temporary distracter in itself. It’s specially designed
for fibula wider distraction in mandible reconstruction. Eighty-nine sets of
DID devices were used in 29 patients (18 males and 11 females). 11 patients
suffered from ameloblastoma of mandible, 7 from malignant tumor, 6 from
odontogenic cyst of mandible, 3 from fibrous dysplasia,
and the other 2 from trauma cases. The age of 29 patients is from 16 to 67
(average 35.6) years old.
Results: During postoperative 1-8.5 years
follow up; the free flaps of all cases were survived. The clinical examination
and X-ray film showed normal contour of mandible. Most cases showed good
osteointegration surround DID, but 15.7% (14/89) of the DID devices were removed
because of the inflammation. The other (84.3%) implants were solid enough to
load the denture force. 12 patients were successfully worn the fixed dental
prosthesis. The outcomes were satisfied.
Conclusion: DID device, which
specially designed for mandibular functional reconstruction with fibula flap,
can help us to simplify convenient procedures to a simultaneous surgery.
