With the evolution of CAD/CAM technology, custom titanium and/or zirconia abutments are increasingly being used, leading to several comparisons in literature, both mechanical and aesthetic, evaluate performance differences between these two types abutments. Therefore, aim this comprehensive review is present most recent data on latest stock abutment applications. The PICO model was used perform...

OBJECTIVE The aim of this study was to investigate the influence of implant crown splinting and the use of angulated abutment on stress distribution in implant body and surrounding bone by three-dimensional finite element analysis. MATERIALS AND METHODS For this study, three models with two implants at the site of mandibular right second premolar and first molar were designed (1): Both implan...

AIM This clinical report describes a time-saving recording procedure for implant prosthesis. BACKGROUND In implant prosthodontics, a few procedures have been suggested to record jaw relationships. Record bases with occlusion rims supported by healing abutments, or screw retained bases are the conventional methods used for mounting definitive implant casts in the articulator. CONCLUSION The ...

Passive fit between prosthesis and implants or abutments is a significant factor in preventing mechanical and biologic failures of implant-supported prostheses. Therefore, impression techniques must transfer the 3D implant position as accurately as possible for a correct superstructure fabrication. A novel impression protocol that uses an individualized open tray design is proposed. It allows t...

The present experiment was performed to study the peri-implant tissue response to non-submerged (1-stage) and initially submerged (2-stage) implant installation procedures. 6 beagle dogs were used. All mandibular premolars and the 1st, 2nd and 3rd maxillary premolars were extracted. After 3 months of healing, 3 fixtures of the Astra Tech System were installed and submerged in the right (or the ...

OBJECTIVES The aim of the present study is to evaluate, in a ligature-induced peri-implantitis model, the efficacy of three antimicrobial glassy coatings in the prevention of biofilm formation, intrasulcular bacterial growth and the resulting peri-implant bone loss. METHODS Mandibular premolars were bilaterally extracted from five beagle dogs. Four dental implants were inserted on each hemiar...

The Brånemark dental implant has undergone progressive development in terms of both the implant body itself and the components connecting the implant to the prosthesis. Many screw and abutment designs have been developed, with various degrees of success. About 15 years ago, CAD (computer-assisted design)-CAM (computer-assisted manufacture) technology was introduced to dentists. More recently CA...

This study aimed to assess marginal bone loss and complication rates of mandibular overdentures retained on two implants with conventional immediate loading protocols. Twenty edentulous patients were treated two-implant-retained new complete maxillary dentures. In one half the sample, loaded immediately by VulkanLoc® abutments. counterpart group, these abutments connected months after implant p...

Soft tissue integration to dental implants Maria Welander Department of Periodontology, Institute of Odontology The Sahlgrenska Academy at University of Gothenburg, Box 450, 405 30 Göteborg, Sweden. Soft tissue integration is a prerequisite for implant success. The role of the soft tissue barrier at implants is to provide an effective seal that protects the underlying bone and prevents access f...

The aim of this study was to evaluate under scanning electron microscopy the characteristics of the implant surface and the gap between the components of two- and one-stage systems. Three two-stage implants coated with RBM and three one-stage implants coated with TPS were selected. In the two-stage implants, the esthetic-cone abutments were adapted and screw tightened with 20 N/cm . In the one ...
