The correct planification of the treatment is the most important element for a success full implant therapy, conventionally bused on the information gathered through models and x-ray images. Thus it is necessary to evaluate carefully the bone quality before the implant insertion to identify the sites on patients potentially at risk and to optimize the implant stability and healing time. Among t...

The single-tooth restoration has become one of the most widely used procedures in implant dentistry. Improvements to the abutment implant interface design, wider implant platforms and the increased use of cemented restorations have greatly enhanced this procedure. Nonetheless, limitations in the volume of underlying bone and heavy occlusal loads, with or without parafunctional habits, still con...

OBJECTIVES The objective of this study is to mathematically evaluate the influence of multiple factors on implant stability quotient values in clinical practice. PATIENTS AND METHODS Resonance frequency analysis was performed at T1 (measured immediately at the time of implant placement) and at T2 (measured before dental restoration) in 177 patients (329 implants). Using a multivariate linear ...

BACKGROUND Further clarification of the early and late response of peri-implant tissues to surgical insertion and loading of dental implants and the potential associations among the various implant-related measures are likely to improve the evaluation/monitoring of implant sites. Thus, analyses were made of the volume and nitric oxide (NO) profile of peri-implant sulcus fluid (PISF), implant st...

The purpose of this study was to evaluate preoperative CT-derived bone densities in Hounsfield units (HU) at implant sites that acquired primary stability, and to compare these values to the optimal bone densities proposed in the literature. Fifty-one patients, 18 males (37 implant sites) and 33 females (67 implant sites) between 2003 and 2010 were assessed. CT data for different jaw sections, ...

The aim of this study was to monitor the changes of viscoelastic properties at bone-implant interface via resonance frequency analysis (RFA) and the Periotest device during the healing process in an experimental rabbit model. Twenty-four dental implants were inserted into the femoral condyles of rabbits. The animals were sacrificed immediately after implant installation or on day 14, 28, or 56 ...

BACKGROUND Decalcified freeze-dried bone allograft (DFDBA) may have the potential to enhance bone formation around dental implants. Our aim in this study was the evaluation and comparison of two types of DFDBA in treatment of dehiscence defects around Euroteknika(®) implants in dogs. METHODS In this prospective clinical trial animal study, all mandibular premolars of three Iranian dogs were e...

BACKGROUND All clinicians are aware of the difficulty of installing a dental implant in posterior maxilla because of proximate position of maxillary sinus, insufficient bone width, and lower bone density. This study is to examine which factors will make the implantation in the posterior maxilla more difficult, and which factors will affect the postoperative implant stability in this region. M...

The purpose of this study was to determine the clinical and biomechanical outcome of two different titanium mini-implant systems activated with different load regimens. A total of 200 mini-implants (102 Abso Anchor and 98 Dual Top) were placed in the mandible of eight Göttinger minipigs. Two implants each were immediately loaded in opposite direction by various forces (100, 300 or 500 cN) throu...
