Abstract This clinical report presents a case of abutment fracture, due to occlusal overload, occurred with an implant-supported restoration on right mandibular first molar of a female patient. After 6 months of prosthetic reconstruction implants, the patient returned to the clinic due to the loss of implant crown. The fractured fragment of the abutment with the screw protec...

providing an esthetic restoration in the anterior region of the mouth has been the basis of peri-implant esthetics. to achieve optimal esthetics, in implant supported restorations, various patient and tooth related factors have to be taken into consideration. peri-implant plastic surgery has been adopted to improve the soft tissue and hard tissue profi les, during and after implant placement. t...

Primary breast augmentation patients have widely varying characteristics of their breast envelope, parenchyma, and adjacent tissues. When preoperative breast implant selection does not specifically address critical soft-tissue parameters individual to each patient, risks of complications increase. Complications that occur from failure to reconcile a patient's wishes for breast size with her ind...

In-vitro, stentless valves have a larger effective orifice area than their stented counterparts. This is best exemplified by the fact that a 25-mm Mosaic valve, which is stented, is manufactured using a 23-mm Freestyle stentless valve. So, in order to end-up with similar effective orifice areas when implanting a stentless valve or a stented valve in the same size left ventricular outflow tract,...

SELECTION CRITERIA The authors used MEDLINE, EMBASE, and CENTRAL (Cochrane Central Register of Controlled Trials) databases to locate studies for this systematic review (SR). For studies to be eligible for this SR, all had to evaluate single-implant restorations with a follow-up of at least 1 year after implant loading. A total of 19 prospective studies met inclusion and exclusion criteria. Fif...

Objectives: Phonemic awareness skills have a significant impact on children speech and language. The purpose of this study was investigating the phonemic awareness skills of children with cochlear implant and normal hearing peers in primary school. Methods: phonemic awareness subscales of phonological awareness test were administered to 30 children with cochlear implantation at the first to ...

background. improving the implantation conditions in order to reduce the failure is always desirable for researchers. the aim of this study was to compare two different types of dental implant materials from biomechnical viewpoint in order to introduce a novel simulation method to select suitable materials for dental implants. methods. in this research, drilling process was performed in the cor...

Dental implant was placed to restore the function of the teeth as well as satisfactory appearance. A great challenge with implant placement and tooth restoration in the aesthetic zone has been presented as a common issue in tooth replacement. The ability of the dental team to re establish normal form and architecture to hard and soft tissue has been concerned [1]. Originally, it was considered ...

Vertical misfit of implant-abutment interface can affect the success of implant treatment; however, currently available modalities have limitations to detect these gaps. This study aimed to evaluate implant-abutment gaps in vitro using optical coherence tomography (OCT). Vertical misfit gaps sized 50, 100, 150, or 200 μm were created between external hexagonal implants and titanium abutments (N...
