The goal of this study was to explore an innovative approach to single-tooth replacement using an individually custom-fabricated, root-analog, hybrid dental implant, in the esthetic zone, to avoid the microgap and micromovements between the implant and abutment. Moreover, the use of burs to prepare the implant recipient site is not necessary in this technique, reducing the bone removal, heating...

abstract fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. this is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). if the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among ...

Occlusal reconstruction of both arches was performed using splinted implant crown pairs. Each pair of crowns was luted to parallel implant abutment pairs and these were screwed and glued into approximately parallel pairs of implant bodies. Paralleling of holes for implant body pairs was performed using a precision guiding device.

With an increase in the availability of implant restorative components, the selection of an appropriate implant abutment for a given clinical situation has become more challenging. This article describes a classification system that will help the practitioner understand the different implant abutments available and therefore be able to understand the selection of abutments for single and multip...

BACKGROUND In cement-retained implant-supported restoration it is important to gain adequate retention of definitive restoration as well as retrievability of prosthesis. The surface of the abutment, alloy of the restoration and the type of cement used influences the retention of the restoration. There is a need to analyze the influence of surface modifications of abutments on the retentive capa...

This article describes and illustrates clinical and laboratory prosthodontic procedures for the use of an implant carrier as surgical guide, positional index, impression coping, verification device, provisional abutment, implant-supported record base, and occlusal registration stop.

PURPOSE To evaluate the influence of different implant numbers and connection types on the biomechanical behavior of mandibular full-arch implant-supported rehabilitation. MATERIALS AND METHODS Computed tomography-based finite element models comprising a totally edentulous mandible and 3.8 × 13-mmdiameter implants, abutments, abutment screws, bar retaining screw, and bar were constructed. Dif...

Background and aims. Because of compromised angulations of implants, the abutments are sometimes prepared. The purpose of this study was to investigate the effect of removing one wall of the implant abutment on the retention of cement-retained crowns. Materials and methods. Four prefabricated abutments were attached to analogues and embedded in acrylic resin blocks. The first abutment was left ...
