Ricostruzione pre-implantare nei mascellari atrofici. Protocollo ambulatoriale

In this study the Authors report some cases of moderate maxillary bone atrophy (Cawood Howell class IV) with a transversal ridge width lower than 4 mm where an implant supported rehabilitation was hardly achievable. Six months after the insertion of an autologous bone graft taken from mental simphysis, 42 implants were positioned in 18 patients (8 males and 10 females, mean age 47.1 years). Implant osteointegration was checked by evaluation of bone loss, soft tissue condition, pocket depth, plaque and bleeding index and patients' satisfaction. At the end of the follow-up no implant was lost. Mean marginal bone loss was 0.17 mm. In the treatment of moderate maxillary atrophies this technique has proved to be successful and predictable. Even if it involves two surgical sites at the same time, thus requiring perfect patient's compliance, it offers the unquestionable advantage of using local anaesthesia only.
