BACKGROUND Stress on the bone surrounding dental micro-implants affects implant success. PURPOSE To compare the stress on the bone surrounding a micro-implant after application of a single force (SF) of 200 g or a composite force (CF) of 200 g and 6 N.mm torque. MATERIALS AND METHODS Finite element models were developed for micro-implant diameters of 1.2, 1.6, and 2.0 mm, and lengths of 6, ...

Implant restorations delivered according to the Brånemark protocol have proven to be highly predictable. To shorten the length of treatment associated with the Brånemark protocol, as well as to preserve soft and hard tissues, newer protocols have focused on reducing or even eliminating the time between tooth extraction and implant placement and between implant placement and prosthetic restorati...

Objective To review and assess the ideal length of electrode in cochlear implant patients for hearing preservation. Methods The English language literature was reviewed for studies including hearing preservation and speech understanding for electrodes of different lengths. Results One prospective trial was found, and there were no studies that randomized patients into different length elect...

PURPOSE To propose a length-and-diameter-based classification scheme for dental implants to standardize terminology in the dental literature and communication between interested parties. MATERIALS AND METHODS This study was mainly based on searching two major resources: published scientific research papers and 14 of the most popular dental implant manufacturers. Indexed databases were searche...

OBJECTIVE Vertical bone loss evaluations in the Nobel Biocare Replace(®) Select Tapered (™) implant system in the human after one-year loading time. MATERIALS AND METHODS This retrospective cross-sectional study was performed on 31 patients (14 men, 17 women; mean age, 60.39 years) receiving 170 implants (mean, 5.48 for each patient) of Groovy and Non-groovy designs in the Nobel Biocare Repla...

BACKGROUND The influences of potential bone-to-implant contact (BIC) area (pBICA), BIC area (BICA), and three dimensional (3D) BIC percentage (3D BIC%; defined as BICA divided by pBICA) in relation to the implant length on initial implant stability were studied. Correlations between these parameters were also evaluated. METHODS Implants with lengths of 8.5, 10, 11.5, and 13 mm were placed in ...

PURPOSE This study evaluated the initial stability of different implants placed above the bone level in different types of bone. MATERIALS AND METHODS As described by Lekholm and Zarb, cortical layers of bovine bone specimens were trimmed to a thickness of 2 mm, 1 mm or totally removed to reproduce bone types II, III, and IV respectively. Three Implant system (Brånemark System® Mk III TiUnite...

Objective: to present the radiographic clinical follow-up of prosthetic rehabilitation a patient with an atrophic mandible, installation short implants associated implant regular length. Method: case report completely edentulous mandible and 6-year conducted at dental clinic Federal University Piauí, Teresina, from February 2011 January 2020. After collecting sociodemographic data, health recor...

Introdouction: Although highly desirable outcomes and longterm survival of dental implant treatments are well documented, implant failures still occur due to various reasons. Several risk factors may impair implant survival including implant dimensions (length, diameter, and implant design), procedures, local bone density at the implant site, and patient-related risk factors such as age, smokin...
