Modern dentistry changed tremendously with implant surgery.For a successful therapy proper diagnosis and treatment plans is required. Teeth loss may be due to physiological as well pathological factors are common. The complete of teeth causes various problems like difficulty in mastication, improper phonetics, unacceptable esthetics patients.Implant supported prosthesis give the dentist an oppo...

This is part of a program devoted to the study of wavelets by making use of their Fourier transforms. We shall rst give a constructive characterization of all minimally-supported-frequencies(m.s.f.) wavelets. Then we use this to construct new m.s.f. wavelets, including ones that are not band-limited. We shall also provide a simple necessary and suucient condition for an m.s.f. wavelet to be ass...

Cochlear implant (CI) users are unable to receive masking release and the reasons are unclear. The present study examines the hypothesis that when listening to speech in fluctuating maskers, CI users cannot fuse the pieces of the message over temporal gaps because they are not able to perceive reliably the information carried by obstruent consonants (e.g., stops). To test this hypothesis, CI us...

The movement to establish uniform standards for the identification of empirically supported treatments (EST) has contributed to an impressive growth in the number of treatments deemed to have strong evidence of their efficacy. Those treatments meeting the most rigorous standards are often granted the label well-established and have been identified in a variety of online and print formats. An im...

provisional cements are commonly used to facilitate retrievability of cement-retained fixed implant restorations; but compromised abutment preparation may affect the retention of implant-retained crowns.the purpose of this study was to investigate the effect of abutment design and type of luting agent on the retentive strength of cement-retained implant restorations.two prefabricated abutments ...

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...

In the last 4 decades, the developments of osseointegrated titanium implants have led to the success of contemporary dentistry. Endosseous implant-supported restorations delivered in accordance with the traditional Branemark protocol have proven to be highly predictable. Today, implants are becoming increasingly common in dental care and provide more therapeutic options, but treatment planning ...

This study evaluated the influence of retorque on loosening torque (Lt) of prosthetic screws in implant-supported dentures with different fit levels. Ten mandibular implant-supported dentures were fabricated and then 20 cast models were then prepared using prosthetic structures to create 2 fit levels: passive fit (Pf) and misfit (Mf). Two tightening techniques were also evaluated: initial torqu...

To evaluate the use of an immediate postoperative prosthesis (IPOP) for transtibial amputees, we compared patient outcomes from a prospective clinical study of 19 patients managed with an IPOP with those of a retrospective review of a matched historic control group of 23 patients managed with standard soft dressings. Data were analyzed with the Student's t-test, and significance was set at P = ...
