BACKGROUND Primary stability after implant placement is essential for osseointegration. It is important to understand the bone/implant interface for analyzing the influence of implant design on primary stability. In this study rigid polyurethane foam is used as artificial bone to evaluate the bone-implant interface and to identify where the torque is being generated during placement. METHODS ...

STATEMENT OF PROBLEM The distal offset placement of a single implant to replace a single tooth would overcome the shortcomings of the placement of a single wide implant in the posterior region. However, long-term evaluation is still-lacking. PURPOSE The purpose of this study was to evaluate the long-term outcomes of patients treated with a single tooth restoration supported by a distal-offset...

After reading this article, the reader should be able to: • describe requirements that would lead to success with immediate implant placement and loading. • describe important surgical considerations to increase the survival of immediate implant restoration. • discuss advantages in the single appointment fabrication of computer-assisted designed and machined porcelain for implant restoration. •...

BACKGROUND The aim of computer-designed surgical templates is to attain higher precision and accuracy of implant placement, particularly for compromised cases. PURPOSE The purpose of this study is to show the benefit of a full three-dimensional virtual workflow to guide implant placement in oligodontia cases where treatment is challenging due compromised bone quantity and limited interdental ...

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...

This case shows an excellent esthetic treatment outcome using implant-retained crowns replacing maxillary laterals and canines in hypodontia patient with unusual incidence of spontaneous diastema closure after the placement of implants. To our knowledge, this is the first case report showing maxillary midline diastema closure after implant placement.

BACKGROUND Deproteinized bovine bone mineral (DBBM) is one of the best-documented bone substitute materials for sinus floor elevation (SFE). PURPOSE DBBM is available in two particle sizes. Large particles are believed to facilitate improved neoangiogenesis compared with small ones. However, their impact on the rate of new bone formation, osteoconduction, and DBBM degradation has never been r...

Implant placement in the anterior maxilla remains a challenge to even the most experienced clinician. Immediate implant placement is a risky procedure in itself and only successful in limited cases. To combine these modalities is expected to have a variety of complications and possible negative outcome. Due to the pressure of patients’ lifestyles and time constricting careers, there is an incre...

tooth/implant supported fixed prostheses may present biomechanical design problems, as the implant is rigidly anchored within the alveolus, whereas the tooth is attached by the periodontal ligament to the bone allowing movement. many clinicians prefer tooth/implant supported fixed prosthesis designs with rigid connectors. however, there are some doubts about the effect of attachment placement i...

introduction: the survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. implant success also is affected by the maintenance of the crestal bone around implants. the aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...
