BACKGROUND Hospital readmissions are associated with higher resource utilization and worse patient outcomes. Causes of unplanned readmission to the hospital are multiple with some being better targets for intervention than others. To understand risk factors for surgical readmission and their incremental contribution to current Veterans Health Administration (VA) surgical quality assessment, the...

Evaluating primary stability is important to predict the prognosis of dental implant treatment. Primary stability is decreased in a low bone density site such as osteoporosis. However, it is difficult to apply in small animal and the effect of the different implant surface topography for the primary stability at low bone density site has not yet fully been investigated. The purpose of the prese...

background and aim:  although there have been substantial developments in dental implant therapies, achieving good implant stability (isq >60) for implants inserted in augmented sinus sites appears to be challenging in comparison with non-augmented sites due to the high prevalence of bone resorption in posterior regions of maxilla. this study aimed to evaluate and compare the time required to a...

PURPOSE To determine the change in stability of single-stage, three different design of implant systems in humans utilizing resonance frequency analysis for early healing period (24 weeks), without loading. MATERIAL AND METHODS Twenty-five patients were included into this study. A total of 45 implants, three different design of implant systems (group A,C,R) were placed in the posterior maxill...

OBJECTIVE This study aimed to compare postoperative cone beam CT (CBCT) imaging to implant stability quotient (ISQ) measurement and direct caliper measurements as a suitable technique to assess bone conduction hearing implant (BCHI) seating and insertion depth. METHODS In vitro, BCHIs were completely (n = 9) and partially inserted (n = 9) in bone blocks of different densities and subsequently...

PURPOSE The purposes of the present study were: to compare the resonance frequency analysis (RFA) values of implant placed in either ramus or calvaria block grafts; and to determine if implant diameter influences RFA implant stability quotient (ISQ) value. MATERIAL AND METHODS This was a retrospective study that included 16 consecutives healthy patients treated with autogenous onlay block gra...

OBJECTIVES The purposes of this study were to examine the correlation between the stability of dental implants and bone formation markers during the healing period and to monitor the stability of dental implants using the resonance frequency analysis (RFA) method. The null hypothesis of the study is no correlation between the stability of dental implant and bone formation markers. METHODS The...

Many surgical procedures use metal implants in bone. The clinical results depend on the strength of the bone holding these implants. Our objective was to show that a drug released from the implant surface can improve parameters reflecting the quality or amount of this bone. Sixteen patients received paired dental titanium implants in the maxilla, in a randomized, double-blinded fashion. One imp...

مقدمه: موفقیت درمان ایمپلنت بستگی به میزان کافی استخوان در محل قرارگیری ایمپلنت دارد. تهیه استخوان اتوژن چه داخل دهانی، چه خارج دهانی کاری ناخوشایند و تهاجمی برای بیمار است. لذا استفاده از جایگزین‏های استخوان برای این امر توصیه می‏شود. هدف مقاله حاضر مقایسه ثبات ایمپلنت‏های قرار گرفته در نواحی تحت درمان با بلوک‏های کورتیکوکنسلوس مینرالیزه با ایمپلنت‏های قرار گرفته در استخوان طبیعی با استفاده از...
