BACKGROUND The aim of the present clinical study was to determine the local bone density in dental implant recipient sites using computerized tomography (CT) and to investigate the influence of local bone density on implant stability parameters and implant success. METHODS A total of 300 implants were placed in 111 patients between 2003 and 2005. The bone density in each implant recipient sit...

The stability of cementless acetabular cups depends on a close fit between the components and reamed acetabular cavities to promote bone ingrowth. Cup performance and stability are affected by both design and environmental (patient-dependent and surgical) factors. This study used a statistically based metamodel to determine the relative influences of design and environmental factors on acetabul...

OBJECTIVES The aim of this paper is to review current investigations on functional assessments of osseointegration and assess correlations to the peri-implant structure. MATERIAL AND METHODS The literature was electronically searched for studies of promoting dental implant osseointegration, functional assessments of implant stability, and finite element (FE) analyses in the field of implant d...

PURPOSE A satisfactory clinical outcome in dental implant treatment relies on primary stability for immediate load bearing. While the geometric design of an implant contributes to mechanical stability, the nature of the implant surface itself is also critically important. Biomechanical and microcomputerized tomographic evaluation of implant osseointegration was performed to compare alternative ...

Nineteen patients previously treated with 52 implants for anchorage of craniofacial prostheses were subjected to implant stability measurements by means of resonance frequency analysis (RFA), six months to 15 years after implant placement. The resonance frequency (RF) of a transducer attached to the implant abutment was measured by using a frequency response analyser, a personal computer (PC) a...

Background Reverse total shoulder arthroplasty is an increasingly utilized treatment option for glenohumeral arthritis with massive, irreparable rotator cuff disruption associated with loss of glenohumeral stability and function. Several reverse shoulder implant designs from different manufacturers have been introduced to the market in recent years. Fixation of the glenoid base plate has been s...

BACKGROUND The attainment of a good primary stability is a necessary condition to ensure the success of osseointegration in implantology. In type IV cancellous bone, however, it is possible that a reduced primary stability can lead to an increased rate of failure. The aim of this study was therefore to determine, with the help of the resonance frequency (Osstell mentor), which technique of impl...

Background: Dentistry science has evolved over the years. According to a 2012 report, submitted by epidemiology department, it was found that 62% people completely lose their teeth out of which 19.2% in mandibular area and 12.2% in maxilla. So the study is done with a specific focus on design of new attachment, in order to increase retention and stability of single implant retained overdentures...
