Dissertação (Mestrado em Odontologia) - Universidade Federal de Goiás, Goiânia, 2009.http://repositorio.bc.ufg.br/tede/handle/tede/4397Several methods have been used to evaluate the bone quality in implant treatment planning, which has been described as important factor for the therapeutic success. However, besides bone quality is a wide term without a clear definition, the evidence of the efficacy of the methods to assess it is scarce. The correlations of these measurements could optimize treatment planning. Aim: To correlate clinical-radiographic subjective and objective methods for evaluating the bone of maxilla and mandible to implant treatment. Materials and Methods: 94 dental implants (Titamax TI Cortical – Neodent, Curitiba, PR, Brazil) were placed into posterior and anterior regions of maxilla (n=40) and mandible (n=54) from 33 patients with the two-stage technique. Implants diameter ranged from 3.75 mm to 5.0 mm and implants length from 9.0 mm to 13.0 mm. The bone was assessed by three independent examiners, using four methods: a) Panoramic and periapical radiographs + tactile perception - Lekholm & Zarb original classification (L&Zoriginal), b) Panoramic and Periapical radiographs – Lekholm & Zarb modified classification (PP), c) trabecular bone pattern – classification of Lindh (Lindh), and d) maximum insertion torque values (MIT) (BLM 600 Plus Engine – Driller, São Paulo, SP, Brazil). Results: There was moderate agreement between L&Zoriginal and PP (Kappa = 0,61). The insertion torque ranged from 15 to 80 Ncm (Mean=33,98; SD=17,15) showing significant correlation with only L&Zoriginal. Conclusions: Changes in the performance of one of the most used bone classification method in implant treatment planning (L&Zoriginal) altered its result. The evaluation of bone quality through L&Zoriginal classification in implant planning can be important for prediction of primary stability.application/pdfAcesso AbertoImplantes dentárioOssoTorquePlanejamentoDental implantsBonePlanningODONTOLOGIA::CLINICA ODONTOLOGICADissertação
