[The role of 3D CT in the treatment of maxillofacial malformations].

The computed tomographic studies obtained routinely in the examination of patients with congenital defects of facial bones can be utilized as a substrate to provide an accurate three-dimensional representation of osseous abnormalities. It is a useful tool for the maxillo-facial surgeon in clinical application, in diagnosis, accurate measurements, preoperative planning and post-operative follow-up. The experience of the Division of Maxillo-Facial Surgery of Bellaria Hospital and of the Radiological Department of Instituto Rizzoli at Bologna is presented.

[The role of the basic skeletal system in the stomatognathic apparatus. A critical review of the literature].

The authors make a literature review on the different interpretations of the stomatognathic apparatus and try to identify any component of it and to underline the importance of the basal skeletal structures (maxilla and mandible). In this study the authors examined three female patients affected by different pathologies (dysfunctional, malformative, and traumatic) treated at the Maxillo-Facial Surgery Department of "La Sapienza" University of Rome; in all cases the basal skeletal structures were involved with a total functional alteration of the stomatognathic apparatus. The primary aim of any maxillo-facial surgical treatment is the restoring of skeletal structural harmony with a re-equilibrium of all the components of the apparatus. In conclusion the authors confirm the importance of the basal skeletal system which is strictly connected to all other elements, for the physiologic structural development and functional harmony of the stomatognathic apparatus.

Histologic analysis of the interface of a titanium implant retrieved from a nonvascularized mandibular block graft after a 10-month loading period.

The combined use of bone grafts and osseointegrated implants appears to improve the long-term prognosis of transplanted bone. One question pertaining to the use of grafted bone is whether the biologic reaction to implants placed in grafted bone is the same as that seen under nongrafted conditions. A mandibular discontinuity defect in a 63-year-old female patient was repaired with a nonvascularized block graft into which 3 titanium implants were placed. After a 10-month loading period, one of the implants was retrieved and treated to obtain thin ground sections. The histologic examination showed mature bone in close contact with the implant surface; no gaps, fibrous tissue, or inflammatory cells were seen at the interface. No resorption phenomena were present. The bone at the interface was highly mineralized. The features of the regenerated bone and the bone-implant interface in grafted bone were similar to those seen in nongrafted situations; no differences were found with results presented in the literature concerned with retrieved implants placed into vascularized grafts.
