Titanium implants and onlay bone graft to the atrophic edentulous maxilla

Nasal Floor Augmentation and Simultaneous Dental Implant Placement: A Case Report

“…Another alternative procedure for treatment of the atrophic maxilla is onlay bone grafting 11,12 . Soft tissue closure poses a limitation for reconstruction of the severely atrophic maxilla.…”

Photoelastic analysis of all-on-four concept using different implants angulations for maxilla

“…In these cases, previous surgical maneuvers, such as interposition graft, obtained from a extra oral donor sites, in Le Fort I osteotomy, techniques of onlay bone graft or sinus lift procedures in the posterior maxilla, are necessary for obtaining bone structure that enables the placement of implants. 2,3,4,5 These techniques have limitations ranging from the need for multiple surgical procedures, greater morbidity, postoperaDeclaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

Implant Supported Maxillary Overdentures

“…Therefore, as part of the PhD research presented in this thesis, a number of randomized controlled trials was developed 13 presumed, but not proven, in the limited number of studies addressing this issue (Ohkubu et al 2010). The thought reason for antagonistic teeth being a risk factor for implant loss and denture problems is the greater mastication force and harmful lateral forces to implants exerted by the patients' antagonistic teeth (Chan et al 1996, Åstrand et al 1996, Kahnberg et al 1999. The bilateral balanced occlusion concept of conventional removable dentures is commonly used in overdenture therapy (Carlsson 2009), but has to be adapted when antagonistic teeth are present.…”

“…A limited number of studies stated a relationship between antagonistic natural teeth and a maxillary overdenture, but could not find a significant difference (Ohkubo et al 2010). The reason 118 for being a risk factor might be a greater mastication force and harmful lateral forces to implants, due to an altered occlusion concept (Chan et al 1996, Åstrand et al 1996, Kahnberg et al 1999. A bilateral balanced occlusion concept of conventional removable dentures is often used in overdenture therapy (Carlsson, 2009).…”
