Aumento verticale nelle atrofie del mascellare superiore: evidenze scientifiche

Objectives: The aim of this paper is to determine which reconstructiveregenerative and/or implant technique is the most effective in vertical bone increase of atrophic alveolar upper jaws. Materials and methods: twelve randomized controlled trials, fulfilling inclusions criteria of Cochrane Collaboration, have been selected and analyzed. Results and Conclusion: in posterior atrophic jaws it's possible to increase bone vertically with success, but complication can often occur. Furthermore it's not clear yet which is the best surgical technique for maxillary sinus lift among those proposed in the literature. When the residual bone crest height is between 4-6 mm, short implants seem to be a good treatment choice because they reduce time and treatment costs and complications. Concerning graft materials that can be used in the sinus lift, we analyzed that they don't have the capacity to influence the final clinical result.
