Immediate Loading Using the Digitalized Customized Restoration of Single-tooth Implants Placed in Fresh Extraction Sockets in the Aesthetic Anterior Maxilla: A 10-Year Prospective Study of Marginal Bone Level.

Aim: The objective of this study was to assess marginal bone level around single implants inserted in fresh extraction sockets in the anterior maxillary region and instantly restored with computer-aided design/computer-aided manufacturing customized temporary crowns cemented on the final abutment.

Materials And Methods: A total of 20 patients (15 females and 5 males, with a mean age of 30 years), where 20 were placed in fresh extraction sockets. After raising a full-thickness flap, atraumatic extraction was performed the implant site was prepared and fixtures were stabilized on the palatal bone wall.

Evaluation of Marginal and Internal Fit at Implant-Abutment Interface of Original and Compatible Nonoriginal Abutments.

Is to measure the peripheral and internal gap at the implant-abutment interface of an implant system connected to its original or compatible non-original abutments. Twenty implants were assembled with four different types of abutments having the same conical internal interface. All abutments were considered compatible with Tx Astra Tech Implant SystemTM.

In Vitro Effect of Mastication on the Retention and Wear of Locator Attachments in a Flat Mandibular Ridge Model.

Purpose: The effect of masticatory loads on the retention of overdenture attachments is poorly documented. The aim of this in vitro study is to assess the effect of simulated mastication on the retentive properties and dimensions of Locator inserts.

Materials And Methods: 30 specimens simulating nonanatomic edentulous flat ridges with two implant replicas each were fabricated.

Effect of Simulated Mastication on the Retention of Locator Attachments for Implant-Supported Overdentures: An In Vitro Pilot Study.

Purpose: Limited information is currently available relative to the effect of masticatory loads on the retentive properties of Locator attachments. The aims of this in vitro study were to assess and compare the effect of simulated mastication on the retention of white, pink, and blue Locator inserts for overdentures retained by 2 implants.

Materials And Methods: Thirty specimens simulating a nonanatomic edentulous flat ridge with two implants and an overdenture were divided into 3 groups according to the color of the fitted insert: transparent clear group (n = 10), pink group (n = 10), and blue group (n = 10).

Leakage evaluation of original and compatible implant-abutment connections: In vitro study using Rhodamine B.

Leakage has been addressed as a major contributing factor to inflammatory reactions at the implant-abutment connection, leading to problems such as oral malodor, inflammation, and marginal bone loss. The aim of this study was to investigate in vitro the leakage at implant-abutment interface of OsseoSpeed™ implants connected to original and compatible abutments. A total of 28 OsseoSpeed implants were divided into four groups (n = 7).

In vitro evaluation of leakage at implant-abutment connection of three implant systems having the same prosthetic interface using rhodamine B.

Objectives. Hollow space between implant and abutment may act as reservoir for commensal and/or pathogenic bacteria representing a potential source of tissue inflammation. Microbial colonization of the interfacial gap may ultimately lead to infection and bone resorption.

Influence of ceramic color and translucency on shade match of CAD/CAM porcelain veneers.

Objective: To investigate the influence of translucency of CAD/CAM ceramic milling blocks on the final color of porcelain veneer cemented using resin cement with two different opacities.

Materials And Methods: A standardized incisal lap preparation was made on a maxillary right central incisor that was duplicated using composite resin material (Z250, A4, 3M ESPE). The resin dies were individually laser scanned (Bluecam, Sirona) in order to build a 3D model of the porcelain veneer on the CAD software (Cerec 3D).

Influence of surgical and prosthetic techniques on marginal bone loss around titanium implants. Part I: immediate loading in fresh extraction sockets.

Purpose: Delayed placement of implant abutments has been associated with peri-implant marginal bone loss; however, long-term results obtained by modifying surgical and prosthetic techniques after implant placement are still lacking. This study aimed to evaluate the marginal bone loss around titanium implants placed in fresh extraction sockets using two loading protocols after a 5-year follow-up period.

Material And Methods: A total of 36 patients received 40 titanium implants (Astra Tech) intended for single-tooth replacement.

Determination of inner implant's volumes: a pilot study for microleakage quantification by stereomicroscopy and spectrophotometry.

Aim: Microleakage quantification of fluids and microorganisms through the connections of different implant parts seems to be sparse. Moreover, no data exist regarding the determination of the volumes of inner parts of dental implant systems. This study aims to determine the volumes of inner parts of three dental implant systems with the same interface and to evaluate the microleakage phenomenon.

In vitro evaluation of the "replica technique" in the measurement of the fit of Procera crowns.

Aim: The objective of this study was to compare the film thickness of a light body polyvinylsiloxane addition silicone impression material using the "replica technique" (RT) to the film thickness resulting from the cementation of Procera copings.

Methods And Materials: Twenty Procera copings were fabricated on ten casts each having one central incisor and one premolar. The thickness of the light body was first measured using the RT; then on the same casts dies were cemented with glass-ionomer cement, sawed, and the film thickness of cement was measured.

Comparative analysis of two techniques for soldered connectors.

The aim of this study was to compare and analyze gas torch and an infrared technique as a heat source. Ney Oro B2, Ney Eclipse and Ney 76 alloys were selected for this purpose. Sixty standardized rods were invested, cast, and sectioned from their respective sprue buttons.
