BACKGROUND The quality of bone is an important factor in the successful implant treatment, and it is evident that higher implant failure is more likely in poor quality of bone. The primary stability of oral implants related to resistance to micromotion during healing is influenced by bone quality, surgical technique, and implant design. PURPOSES The aims of this biomechanical study were to ex...

Aims: There is a controversy regarding the indication of implant insertion into sockets infected teeth. This study aimed to evaluate outcome immediate implants replacing periapically teeth utilizing Resonance Frequency Analysis (RFA) method. Materials and Methods: Preoperatively, clinical, radiographic examination accomplished for patients. After anesthetizing surgical area, accused tooth extra...

Resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The stability quotient (ISQ) measure obtained by different RFA devices; however, inter- and intra-rater reliability agreement of these instruments remain unknown. Thirty implants were placed in three pig mandibles. ISQ was measured parallel perpendicular (lingual) to peg axis with Osstell® Beacon, Pe...

PURPOSE The objective of the present study was to measure the implant stability quotient (ISQ) values during the osseointegration period, and determine the factors that affect implant stability. MATERIALS AND METHODS To measure implant stability, resonance frequency analysis (RFA) was performed in 24 patients (12 women, 12 men) with a total 64 Defcon implants (10 anterior maxilla, 12 posterio...

BACKGROUND Chemical modifications of the dental implant surface that improve the wettability result in a faster and better osseointegration. PURPOSE The aim of this randomized clinical trial was to evaluate the implant stability quotient (ISQ) of implants with similar designs, treated with 2 surfaces, sandblasted acid-etched (SAE) and hydrophilic SAE, within the initial 16 weeks of healing. ...

INTRODUCTION Aim of the study was to assess the impact of the length of mini-implants inserted in the midpalatal region on the stability at the initial healing period. METHODS A sample of 20 consecutively treated patients (15.6 ± 7.2 years) was examined. A long mini-implant with a length of 11 mm and a diameter of 2 mm was inserted into the anterior palate of each patient. Resonance frequency...

decreasing qualitative aspects of residential environments is a real problem in recent public housing of kerman. this article is concentrated on surveying the impact of in-between spaces on residential environments quality (req), to evaluate different kinds of it and to determine interrelation of two main components: residents individual characteristics and characteristics of in-between spaces....

background and aims. resonance frequency analysis (rfa) offers a noninvasive clinical measurement of stability and osseointegration of implants; it is a useful tool to establish implant loading time. the rfa values are represented by a quantitative unit called the implant stability quotient (isq) on a scale from 1 to 100. the aim of the present study was to measure the stability of astra tech a...

This case series evaluated the clinical efficacy of autogenous tooth bone graft material (AutoBT) in alveolar ridge preservation of an extraction socket. Thirteen patients who received extraction socket graft using AutoBT followed by delayed implant placements from Nov. 2008 to Aug. 2010 were evaluated. A total of fifteen implants were placed. The primary and secondary stability of the placed i...
