The rehabilitation of patients with acquired defects of the maxilla is a challenge in terms of reestablishing oronasal separation. In most patients these goals are met by means of prosthetic rehabilitation with an obturator prosthesis. If the remaining dentition does not offer sufficient retention and support, the placement of zygoma implants can enhance the stability of the prosthesis. Due to ...

context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...

Implants placed shortly after tooth extraction have proven to be a predictable treatment modality. The number of surgical appointments and length of surgical phase are reduced, thereby preserving hard and soft tissue configuration. However, there are some limitations to early implant placement. These include a probable lack of soft tissue closure over the extraction site, difficulty in matching...

PURPOSE The design of the attachment must provide an optimum stress distribution around the implant. In this study, for implant overdentures with a bar/clip attachment or a locator attachment, the stress transmitted to the implant in accordance with the change in the denture base length and the vertical pressure was measured and analyzed. MATERIALS AND METHODS Test model was created with epox...

OBJECTIVES To systematically review risks of mechanical impact on peri-implant strain and prosthetic influence on stability across finite element studies. MATERIAL AND METHODS An online literature search was performed on MEDLINE and EMBASE databases published between 2011 and 2016. Following keywords tiered screening and selection of the title, abstract and full-text were performed. Studies o...

OBJECTIVE To assess the performance of short nanorough implants (8.5 mm in length) provided with either a platform-matched or a platform-switched implant-abutment connection, placed in the resorbed posterior region of partially dentate patients. MATERIALS AND METHODS A total of 149 implants with a dual-acid surface and a discrete crystalline deposition of nanometer-sized CaP particles, with e...

Introduction: Congenital and acquired penile curvature has a negative impact on penile aesthetics, sexual capabilities, and male psychology. Surgical procedures yield satisfactory correction of curvature, but are usually associated with penile shortening and palpable suture material and nodules under the skin, resulting in patient dissatisfaction. Aims: To present a novel technique using a subc...

Cochlear implants partially restore auditory sensation in individuals affected by severe to profound hearing loss. We investigated vowel detection, identification, and discrimination in a group of congenitally-deafened, unilaterally-implanted, Italian children and in a group of age-matched controls, by combining behavioral and neurophysiologic measures. Comparable vowel identification and discr...
