STATEMENT OF PROBLEM The replacement of lost teeth with dental implants is a widespread treatment whose associated problems are also frequently encountered. Nevertheless, the factors associated with early implant failure have not been well documented. Further analyses of the factors influencing osseointegration establishment are required to maximize the predictability of the procedure and minim...

The present study applied FE methods to evaluate the biomechanical effects induced by implant configuration and bone quality within an augmented posterior maxilla. The aim of this study was to ascertain the optimal choice of implant on the basis of actual bone conditions. A couple of simplified maxillary segment models vary in bone quality (D2, D3 and D4 type) were constructed. Imlants were emb...

BACKGROUND AND PURPOSE Metaphyseal anchored short-stem hip implants were designed to improve load transmission and preserve femoral bone stock. Until now, only few outcome data have been available and migration studies are one of the few ways of obtaining data that are predictive of implant survival. We therefore evaluated a metaphyseal anchored short-stem hip implant by Ein Bild Roentgen Analy...

the effect of melatonin and bromocryptine on body weight, fibre shedding and cashmere traits was investigated by using 24 raeini female goats (2-3 years old) in four experimental groups: control (c); melatonin (mi) implant (18 mg at first and repeated after 40 days), bromocryptine (b) injection, (0.5 mg/kg bw per three days) melatonin and bromocryptine implant and injection (mib). all goats wer...

PURPOSE Clarification of the protocol for using short implants is required to enable widespread use of short implants as an available treatment option. The purpose of this study was to investigate the influences of implant length and diameter, bicortical anchorage, and sinus augmentation on peri-implant cortical bone stress by three-dimensional finite element analysis. MATERIALS AND METHODS F...

OBJECTIVES This study investigates the outcome of short implants additionally placed with longer implants to support a maxillary overdenture. MATERIALS AND METHODS Twelve patients received six implants to support a maxillary overdenture. Only one patient still had two molars in the maxilla, while the others had no remaining teeth. The status of the opposing arch was diverse. The distal implan...

OBJECTIVES The aim of the present study was to evaluate the influence of implant length and diameter on implant survival. METHODS A retrospective cohort of 787 consecutive patients from 2 private practices between the years 2008 and 2011 had been evaluated. Patient demographics, site and implant characteristics, and time of follow-up were recorded from the medical files. RESULTS Overall, 30...

Short-stem total hip arthroplasty has been proposed as a bone-conserving procedure for the younger and more active population undergoing total hip arthroplasty. Although various short stems are currently available, no studies compare the outcomes between these stems. The aim of the current study was to conduct a systematic review of the clinical and radiographic outcomes of the various short st...

AIM To test whether or not the use of short dental implants (6 mm) results in an implant survival rate similar to long implants (11-15 mm) in combination with sinus grafting. METHODS This multicentre study enrolled 101 patients with a posterior maxillary bone height of 5-7 mm. Patients randomly received short implants (6 mm) (group short) or long implants (11-15 mm) with sinus grafting (group g...
