Abstract
BACKGROUND: Bone deficits of the midface can be observed following tumor surgery,
facial traumas or malformations, and can determine aesthetic deformities
requiring surgical corrections. The goal of this study is to illustrate the 23
years experience of the Maxillo-Facial Department of the "La Sapienza" University
of Rome, in surgical correction of middle third bone loss for aesthetic
improvement, and to compare postsurgical results from the use of biomaterials and
homologous bone grafts.
METHODS: From January 1977 to January 2000, 18 patients were surgically treated
with bone grafts for bone deficit of the midface requiring aesthetic
improvements, and 23 received biomaterial placement in the same district. A
retrospective analysis regarding aesthetic improvements following corrective
(reconstructive) surgery was carried out in order to compare long-term results
obtained with bone grafts and biomaterials.
RESULTS: Of the 19 implants of the zygomatic bone, 1 patient suffered from
infection, observ-ed on the 8th day, following iliac bone graft in the maxillary
area. Of the 32 prostheses, 7 became infected and in 1 case the material became
exposed: Proplast(R) became infected 2 times, Gore-tex(R) 3 times and 1 time
became exposed; 2 of the 24 Medpor(R) implants resulted in infection. The
employment of bone graft obtained a good short term aesthetic result. Medpor(R)
employment, was evaluated as an optimal aesthetic improvement. We cannot evaluate
the results obtained with Gore-tex(R) and Proplast(R) because of the few cases
treated. Anyway we consider unsatisfactory the corrections obtained with these 2
materials.
CONCLUSIONS: Homologous bone grafts are still considered as the best choice when
a further fixture positioning is planned for prosthetic rehabilitation of the
alveolar ridge of the upper jaw or mandible. At the present time, some
biomaterials are the definitive solution for restoring facial harmony in the 3
spatial dimensions.
