This case report demonstrates 3-dimensional restoration of a severely-damaged alveolar ridge

The purpose of this study was to report the clinical results obtained with 5-mm diameter regular-platform Brinemark implants after 2 to 5 years of follow-up. A secondary aim was to compare the clinical outcome to that of adjacently placed standard 3.75-mm fixtures in the same patients under the same operative condition and in the same pros- thetic construction.

Bone resorption following tooth loss often limits the quantity of bone available for implant placement. The purpose of the present study was to evaluate the clinical outcome of 10-mm or shorter machined-surface implants when used exclusively in the treatment of various forms of edentulism.

Purpose: To investigate the effect of type-2 diabetes on implant survival and complication rate.

Purpose: Implants shorter than 10 mm can be a long-term solution for sites with limited bone height. The purpose of this study was to determine the influence of some prosthetic factors on the survival and complication rates

L’évolution des séquences d’instruments endodontiques a permis, ces vingt dernières années, de simpli er les traitements cana- laires et de les rendre prédictibles. La géo- métrie instrumentale est de plus en plus complexe pour répondre aux nécessités d’ef cacité de mise en forme. Leurs proprié- tés mécaniques ont aussi été optimisées par l’utilisation de traitements thermiques qui modi ent la phase cristalline du nickel-titane

Xenografts have been used extensively, either alone or in combination with autogenous bone, in sinus floor elevation techniques. However, controversy exists regarding the need to cover the lateral osteotomy site with a membrane. Also, the healing period before loading remains undefined when machined-surface implants are placed. Twenty-nine patients showing reduced bone volume in the pos- terior maxilla had 61 Brånemark System implants placed in 30 sinuses augmented with a lateral osteotomy approach

Purpose: To determine the potential complications and clinical outcomes using the lateral sinus elevation technique with window repositioning.

Aim: The purpose of this study was to evaluate the fracture resistance and failure location of single-tooth, implant-supported, all-ceramic restorations on different implant abutments subjected to a maximum load.

Abstract This study was designed to determine if the alloy composition shares an influence with the geometric design on the physical behavior of nickel-titanium rotary endodontic instruments. ProTaper, HERO, and K3 files were selected. After sterilized and cleaning with alcohol, surface analysis was performed using energy dispersive spectroscopy. Measurements were performed on the active part and on the shank. SEM images of fractured instruments were also obtained and assessed. All three types of instruments were composed mainly of Nickel (54.3%, SD
0.8) and Titanium (45.2%, SD
0.9). SEM images revealed similar aspect with the presence of Kirkendall voids regularly distributed in the alloy. The results indicate that the difference in properties and behavior of these three endodontic rotary shaping instruments is solely related to the respective geometric characteristics of the instrument design.

Purpose: The aim of this study was to compare the bond strength obtained on root canal walls when using two different adhesive systems to bond a fiber reinforced composite (FRC) post inside a root canal and to evaluate the type of failure at the resin-dentine interface.

Objective: The aim of this study was to investigate the influence of a fiber post on the fracture mechanics of zirconia crowns inserted over endodontically treated teeth with different extent of coronal damage.

Purpose: To investigate the relationship between post and core build-up materials on the fracture resistance of endodontically treated teeth restored with different onlay restorations.

Purpose: To evaluate the interfacial microtensile bond strength between a fiber-reinforced post (Rely X Post) and a core material (Multicore Flow) after placing different bonding agents.

Objective: The aim of this study was to investigate the influence of a fiber post on the fracture mechanics of zirconia crowns inserted over endodontically treated teeth with different extent of coronal damage.

Abstract The elastic modulus of the restorative material is important in restoring endodontically treated teeth. This study aimed to compare the fracture resistance and failure patterns of 90 mandibular molars restored using resin composites with or without fiber posts, with respect to the number of residual cavity walls. Five restoration types were performed corresponding to different wall defects (groups 1-5).

We report here a case of titanium dental implant allergy that caused rapid implant loss following an acute inflammatory reaction and its successful replacement by a one-piece zirconium implant.
