RESUMO
OBJECTIVE: To present a simple and objective method for the planning of maxillary implant reconstruction with autogenous bone graft in maxilla atrophy. METHODS: Lateral cephalometric radiographs were performed with a metallic marker placed inside an acrylic-coated model, followed by cephalometric studies, to predict the most adequate grafting method for maxillary reconstruction in 13 edentulous patients (2 males and 11 females) whose age ranged from 27 to 47 years (mean age 37.9 years). RESULTS: It was possible to predict the type of maxillary reconstruction in all patients. Onlay graft was used in 12 patients. One patient was submitted to LeFort I reconstruction with interpositional graft. After 8 months, the patients received a total of 95 standard implants. The success rate was 94.7% with loss of five implants. Rehabilitation was performed with protocol-type prostheses. All patients have been followed for more than 18 months since osseointegration. CONCLUSIONS: This simple and objective method provided a useful contribution to maxillary reconstruction, and to the functional and aesthetic rehabilitation of the patients.

OBJECTIVES: The purpose of this study was to evaluate the reliability of direct and indirect measurement methods, with a view to standardizing morphometry instruments. METHODS: Dry skulls of 30 New Zealand rabbits were used. Measurements were made with a transparent flexible plastic ruler, an EKG calliper and a digital calliper, as well as with computerized tomography and lateral radiographs for direct and indirect analysis of distances and angles. RESULTS: The different instruments studied showed only partial agreement. CONCLUSIONS: A standardized and reliable direct or indirect morphometry method for the craniofacial skeleton of rabbits still has not been determined.
