OBJECTIVE To evaluate the predictability of narrow-diameter implants as a treatment option in routine clinical practice. A literature review was performed of studies reporting clinical results obtained with these implants. Survival rates, peri-implant bone loss and related complications were evaluated. The working hypothesis was that narrow-diameter implants offer clinical results similar to th...

For optimizing functional and esthetic implant therapy results, sufficient bone amount is required at the reception site. A reduced buccolingual ridge dimension may not allow the placement of a standard-diameter implant without the risk of implant thread exposure. In such situations, lateral bone augmentation procedures can be performed that would allow a restorative-driven placement of standar...

BACKGROUND To our knowledge, no study has evaluated the success or survival rate of single-tooth implants that replaced missing maxillary and mandibular second molars. The purpose of the present study was to evaluate the 1- to 5-year cumulative survival rate (CSR) for single-tooth implants placed in the second molar region and the effects of associated factors. METHODS Four hundred eighty-nin...

OBJECTIVE The aim of this study was to compare crestal bone-level changes, soft tissue parameters and implant success and survival between small-diameter implants made of titanium/zirconium (TiZr) alloy or of Grade IV titanium (Ti) in edentulous mandibles restored with removable overdentures. MATERIALS AND METHODS This was a randomized, controlled, double-blind, split-mouth multicenter clinic...

INTRODUCTION Despite the high success rates of endosseous oral implants, restrictions have been advocated to their placement with regard to the bone available in height and volume. The use of short or nonstandard-diameter implants could be one way to overcome this limitation. MATERIAL AND METHODS In order to explore the relationship between implant survival rates and their length and diameter...

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...

BACKGROUND Fractured connections between implants and implant abutments or abutment screws are frequently encountered in a clinical setting. The purpose of this study was to investigate fracture strength using a torsion test at the interface between the implant and the abutment. METHODS Thirty screw-type implant with diameters of 3.3, 3.8, 4.3, 5.0, and 6.0 mm were submitted to a torsion test...

Objective: At present, treatment of edentulous areas with implant-supported prosthesis has greatly increased. The aim of this study was to assess the survival rate of implants with different diameters. Methods: This retrospective study was conducted on 239 warfare victims presenting to Qazi Tabatabaie Clinic during 2000-2010. A total of 1,649 implants were placed. The success criteria included ...

BACKGROUND High-profile round saline breast implants that permit a better match of implant diameter to the base diameter of the breast are now available. OBJECTIVE The advantages and disadvantages of high-profile breast implants are defined from the point of view of the author's initial experience. METHODS The maximal optimal breast implant was determined on the basis of preoperative measur...
