PURPOSE This study was undertaken to assess the predictive usefulness of preoperative bone density, as measured by computed tomography (CT), and the intraoperative implant stability measures of insertion torque (IT), Periotest values (PTV), and resonance frequency analysis (ie, implant stability quotient [ISQ]) toward developing an algorithm for successful immediate loading, one-step exposure, ...

Purpose. The purpose of this finite element study was to compare stresses, strains, and displacements of double versus single implant, in immediate loading for replacing mandibular molar. Materials and Methods. Two 3D FEM models were made to simulate implant designs. The first model used 6 mm wide-diameter implant to support a single molar crown. The second model used 3.75-3.75 double implant d...

OBJECTIVES To retrospectively evaluate the clinical outcome of tapered, multithreaded implants (Tapered Screw-Vent MTX; Zimmer Dental, Inc, Carlsbad, CA) with an emphasis on periimplant crestal bone status around those placed delayed and immediately in the posterior and anterior maxilla. METHODS Chart reviews were performed on 46 patients who had been treated with 173 implants replacing one o...

Background: Dental implant therapy is still considered an evolving field in Nepal, with most dentists favoring placement following the delayed loading protocol (>3 months) even rehabilitation of missing anterior teeth. There need to understand clinical difference between immediate and protocols dental implants. With advent implants, instant addition better esthetics self-confidence can be ob...

OBJECTIVES The objective of this study is compare the rate of marginal bone resorption around hydroxyapatite-coated implants given different loading times in order to evaluate their stability. MATERIALS AND METHODS The study was conducted retrospectively for one year, targeting 41 patients whose treatment areas were the posterior maxilla and the mandible. Osstem TS III HA (Osstem Implant Co.,...

Implant-abutment assemblies are usually subject to long-term cyclic loading. To evaluate the dynamic fatigue performance of implant-abutment assemblies with different tightening torque values, thirty implant-abutment assemblies (Zimmer Dental, Carlsbad, CA, USA) were randomly assigned to three tightening groups (24 Ncm; 30 Ncm; 36 Ncm), each consisted of 10 implants. Five specimens from each gr...

AIM OF THE STUDY The aim of the study was to check the stress absorbed by the bone around mini over-denture dental implant with and without acrylonitrile O-ring under two different loading conditions. The initial stress absorbed by the implant plays a significant role in the success of the immediate loading implants. MATERIALS AND METHODS A three-dimensional finite element analysis using Pro-...

objectives : microbial leakage through the implant-abutment (i-a) interface results in bacterial colonization in two-piece implants. the aim of this study was to compare microleakage rates in three types of replace abutments namely snappy, goldadapt, and customized ceramic using radiotracing. materials and methods: three groups, one for each abutment type, of five implants and one positive and ...
