introduction: the purpose of this study was to compare the heat generated from different depths of an implant drilling site with and without a sleeve. materials and methods: in this study, 60 cortical bone samples were used and a load of 2.0 kg was applied. rilling for implant surgery, we used a diameter of 4.3 mm and a normal sleeve. heat was measured from 3 different depths(3,6, and 9 mms). d...

accurate delivery of torque to implant screws is critical to generate ideal preload in the screw joint and to offer protection against screw loosening. mechanical torque-limiting devices (mtlds) are available for this reason. in this study, the accuracy of one type of friction-style and two types of spring-style mtlds at baseline, following fatigue conditions and sterilization processes were de...

The aim of the study was to investigate the clinical-anatomical peculiarities of edentulous mandibular dental segments (eMDS), situated in the posterior mandible, as well as to estimate the possibility of dental implantation for every clinical-anatomical eMDS type. One hundred and ninety-eight patients were examined, 88 male and 110 female. Orthopantomography, computer tomography, clinical exam...

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 wer...

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...

OBJECTIVES The accuracy of two commercially available systems for image-guided dental implant insertion based on infrared tracking cameras was compared with manual implantation. MATERIAL AND METHODS Phantoms of partially edentulous mandibles were used. In a master phantom, pilot boreholes for dental implants were placed. These boreholes were reproduced in slave phantoms using either of the tw...

Dental implants constitute a well-established approach for replacement of lost teeth with titanium being the most favored material for implantation. However, titanium has its limitations in esthetically demanding cases and neither the form nor material of such implants has changed much over the past 40 years. Immediate implantation has been introduced to overcome the disadvantages of convention...

PURPOSE Bisphosphonate (BP)-related osteonecrosis of the jaw (BRONJ) is a side effect of BP therapy. Dental implants are believed to be a risk factor for developing BRONJ. In the present study, we analyzed the interval to the development of BRONJ in patients treated with BP who had received dental implants. PATIENTS AND METHODS Patients with dental implants and established BRONJ were evaluate...

OBJECTIVES Using the finite element method (FEM), the insertion process of a dental implant into a section of the human mandible is analysed. The ultimate aim of this article is to advance the use of an innovative engineering approach in dental practices, especially in the process of dental implantation. MATERIAL AND METHODS The FEM and analysis techniques are used to replicate and evaluate t...
