OBJECTIVES Risk factors in oral implantology are defined as local or systemic conditions that increase failure rates. The purpose of this paper is to evaluate the long-term survival rate of dental implants placed in patients presenting mechanical risk factors. MATERIALS AND METHODS This retrospective study was conducted only with patients presenting at least one of the following risk factors ...

The aim of present study is to evaluate the implant stability, operative time and patient satisfaction of short dental implants (6mm) alone, short dental implants (8mm) combined with OSFE and standard dental implants (10mm) combined with OSFE for treating atrophic posterior maxilla of partially edentulous. 33 patients with 33 implants (Group 1: 9, Group 2: 12, Group 3: 12) were included in the ...

This retrospective study involved Japanese patients with prostheses supported by Brånemark implants following maxillectomy. Questionnaires were sent to 75 institutions, and data on 19 patients were collected from 8 institutions. The mean age of patients at the time of implant placement was 64.2 years (range 22 to 82 years). The mean follow-up time was 27.6 months. Of the 81 implants placed, 16 ...

BACKGROUND The aim of this study is to evaluate the implant survival, the implant-crown success, and the prosthetic complications of 2,549 Morse taper interference-fit connection implants. METHODS A total of 2,549 Morse taper connection implants were inserted in 893 patients from January 2003 until December 2008. At each annual recall, clinical, radiographic, and prosthetic parameters were as...

PURPOSE The aim of this study was to describe the didactic and clinical undergraduate implant dentistry program of the Albert-Ludwigs University, Freiburg, Germany, with emphasis on the clinical implant experience. MATERIALS AND METHODS A detailed description of the implant curriculum at Albert-Ludwigs University is given with documented exemplary cases and additional flow charts. RESULTS A...

PURPOSE The purpose of this clinical investigation was to evaluate the treatment outcome with zygoma implants with regard to implant survival, patient satisfaction, and function of prosthesis replacement after 3 years. PATIENTS AND METHODS The treatment outcome of 76 patients treated with 145 zygoma fixtures at 16 centers was evaluated with regard to implant survival. Status of peri-implant m...

BACKGROUND The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, ...

Objective. To evaluate horizontal bone gain and implant survival and complication rates in patients treated with titanium meshes placed simultaneously with dental implants and fixed over them. Methods. Twenty-five patients treated with 40 implants and simultaneous guided bone regeneration with titanium meshes (i-Gen®, MegaGen, Gyeongbuk, Republic of Korea) were selected for inclusion in the pre...

PURPOSE To evaluate whether systemic diseases with/without systemic medication increase the risk of implant failure and therefore diminish success and survival rates of dental implants. MATERIALS AND METHODS A MEDLINE search was undertaken to find human studies reporting implant survival in subjects treated with osseointegrated dental implants who were diagnosed with at least one of 12 system...

OBJECTIVE In the last decade, several investigators have reported that standard length implants (SLIs) have achieved excellent results but no report regarding SLIs (i.e. SLI, length=13 mm) inserted into alveolar bone sites previously augmented with frozen bone (FB) is available. The aim of this study was to evaluate the clinical outcome of SLIs inserted into alveolar bone sites previously augme...
