This paper discusses the importance of internal service quality (ISQ) in the service industry. A three-tiered conceptual model of ISQ is developed based on the literature review. The first tier of our proposed model is the determinant of ISQ. The second tier, which is the centre of the model, is ISQ. The third tier of the model is the consequences of ISQ; that is trust, employee turnover, and f...

OBJECTIVES This study identified potential general influencing factors for a mathematical prediction of implant stability quotient (ISQ) values in clinical practice. METHODS We collected the ISQ values of 557 implants from 2 different brands (SICace and Osstem) placed by 2 surgeons in 336 patients. Surgeon 1 placed 329 SICace implants, and surgeon 2 placed 113 SICace implants and 115 Osstem i...

AIM To evaluate the primary and secondary stability of implants in the posterior maxilla. METHODS Patients were allocated into three groups: (A) native bone, (B) partially regenerated bone, and (C) nearly totally regenerated bone. Insertion torque (IT) and implant stability quotient (ISQ) were measured at placement, to evaluate whether satisfactory high primary stability (IT ≥ 45 N/cm; ISQ ≥ ...

One of the most important reasons for information systems failure is lack of quality. Information Systems Quality (ISQ) evaluation is important to prevent the lack of quality. ISQ evaluation is one of the most important Multi-Criteria Decision Making (MCDM) problems. The concept of Single Valued Triangular Neutrosophic Numbers (SVTrN-numbers) is a generalization of fuzzy set and intuitionistic ...

The resonance frequency analysis (RFA) technique is widely used for stability assessments of dental implants. The technique makes use of a transducer peg, which is attached to the implant and excited over a range of frequencies by electro-magnetic waves to measure the resonance frequency (RF) of the peg. The underlying RF in Hz is then translated to an Implant Stability Quotient (ISQ) on a scal...

PURPOSE Implant stability quotient (ISQ) values have been supposed to predict implant stability. However, the relationship between ISQ values and bone-to-implant contact ratio (BIC%) which is one of the predictors of implant stability is still unclear. The aim of the present study was to evaluate initial ISQ values in relation to BIC% using rabbit model. MATERIALS AND METHODS Four New Zealand...

One of the conditions for ensuring success in implant surgery with an immediate loading (IL) protocol is to achieve maximum primary stability (PS) through the use of dental implants with the appropriate design and surface and a properly prepared osseous bed. The aim of this study was to assess the stability, degree of osseointegration, and success rate after inserting an implant with IL in an o...

STATEMENT OF PROBLEM How the ISQ values measured by Osstell™ and Osstell™ Mentor are related, and whether the ISQ values acquired from the two machines changes in accordance with changes in implant stability are not yet fully understood. PURPOSE The aim of this study was to find out correlation between the ISQ values acquired from Osstell™ and Osstell™ Mentor, and to evaluate the clinical eff...

The aim of the present study was to monitor implant stability after sinus floor elevation with two biomaterials during the first six months of healing by resonance frequency analysis (RFA), and how physico-chemical properties affect the implant stability quotient (ISQ) at the placement and healing sites. Bilateral maxillary sinus augmentation was performed in 10 patients in a split-mouth design...

OBJECTIVE Comparing reliability of Osstell Mentor and Osstell ISQ in implant stability measurement, and assessing whether their measurements are comparable. MATERIALS AND METHOD Implant stability was measured with both devices on 58 implants in 15 patients. Six measurements were completed with each device with 2 different transducers (3 measurements with each transducer), that is, 12 measurem...
