Outfracture Osteotomy Sinus Graft: A Modified Technique Convenient for Maxillary Sinus Lifting
نویسندگان
چکیده
Edentulous alveolar ridges always demonstrate atrophy when left alone without dental treatment, making rehabilitaion of masticatory function in this atrophic ridge in need of auxilliary augmentation procedures. This is always challenging in posterior maxil‐ lary edentulous area because local anatomical condition of this region is easily ham‐ pered as masticatory force in the posterior dentition and maxillary sinus is three times greater and the antrum is always subject to pneumatization; thus, facilitating the alveo‐ lar bone resorption of the maxillary sinus floor. The best way for a functional rehabili‐ tation of the edentulous alveolar ridge is a dental implant; augmentation sinus surgery can circumvent the anatomical problems (i.e. lack of bone) associated with implant fix‐ ture installation.

متن کاملA Surgical Variant of the Pre-Lacrimal Approach to the Maxillary Sinus
Introduction: When dealing with maxillary sinus pathology, some areas of the sinus remain difficult to examine. In this regard, the pre-lacrimal approach is a minimally invasive technique to reach anterolateral areas of the maxillary sinus while preserving the physiological nasal function. Materials and Methods: The present study aimed to provide technical hints relate...
متن کاملLateral trap-door window approach with maxillary sinus membrane lifting for dental implant placement in atrophied edentulous alveolar ridge.
One of the most challenging and technically sensitive surgical procedures in conjunction with dental implant rehabilitation is sinus membrane lifting to increase the bone height or volume from the maxillary sinus floor. This important preprosthetic surgical technique has been available for >15 years, making possible the creation of bone volume in the edentulous posterior maxilla for the placeme...

We retrospectively reviewed a new preimplantation regenerative augmentation technique for a severely atrophic posterior maxilla using sinus lifting with simultaneous alveolar distraction, together with long-term oral rehabilitation with implants. We also analyzed the regenerated bone histomorphologically. This study included 25 maxillary sinus sites in 17 patients. The technique consisted of al...

Background and Aim: Understanding the vascular anatomy of the maxillary sinus plays an important role in the success of sinus grafting and determining the location of lateral osteotomy. The aim of the present study was to localize the posterior superior al-veolar artery (PSAA) and to measure the distance from this vascular canal to the maxil-lary sinus floor and alveolar crest by cone-beam comp...
