Summary:

Desde as pioneiras investigações efe c tuadas por Bränemarke colegas que a proc u ra de soluções previsíveis a longo prazo tem vindo a suscitar discussões acerca dos materiais e técnicas utilizadas em implantologia. Uma dessas questões está relacionada com o tipo de conexão entre o implante e a restauração suprajacente. Esta poderá ser globalmente dividida em três categorias: retenção por aparafusamento oclusal, por aparafusamento lateral e por cimentação1. Existem, para além destas, outras técnicas alternativas, como a combinação da cimentação e do aparafusamento na mesma prótese (próteses cimentadas, com parafusos linguais ou palatinos) . Apesar da grande variedade de opções que temos actualmente ao nosso dispor, existe ainda alguma falta de dados baseados em evidência científica que nos permitam escolher a melhor alternativa2, sendo a opção muitas vezes efectuada com base no “gosto” pessoal de cada clínico. O objectivo deste artigo é estabelecer uma comparação entre a prostodontia implanto - suportada aparafusada e cimentada, a nível estético e funcional, focando as principais diferenças e vantagens de cada uma das opções.

Contaminated Implants Raise Global Concern Among Dentists

Contaminated Implants Raise Global Concern Among Dentists
There is a problem that many implantologists are not aware of: recent analyses of dental implants using scanning electron microscopy indicate that an alarming number of sterile-packaged implants are contaminated. The authors assumed that either foreign particles had found their way into the osseous bed during the implant placement procedure or the implant material itself was contaminated.

Aesthetic Enhancement of Anterior Dental Implants with the Use of Tapered Osteotomes & Soft Tissue Manipluation

Aesthetic Enhancement of Anterior Dental Implants with the Use of Tapered Osteotomes & Soft Tissue Manipluation
An adequate bone base is usually a prerequisite for functionally and aesthetically optimal reconstruction of the soft tissue architecture around a dental implant. In patients with sufficient bone height but insufficient bone width as a result of tooth loss, a jaw enlargement technique with osteotomes combined with soft tissue manipulation may be utilized to facilitate proper implant placement while concomitantly optimizing the aes thetics of the final implant prosthesis. The learning objective of…

Instrumentation for Modern Day Implant Surgery

Instrumentation for Modern Day Implant Surgery
Public awareness of the aesthetic possibilities through the replacement of missing or nonsalvageable teeth has been elevated with advances in dental implant therapy and related hard and soft tissue regenerative therapies. This has led to an increase in the fabrication of fixed prostheses supported by either natural teeth, dental implants, or removable prostheses anchored by implants rather than conventional tissue- or tooth-supported partial dentures.

Ridge Expansion, GBR & Meshes: Decision Making in Clinical Practice
A variety of bone augmentation procedures are currently available at use to the clinician. Techniques of variable complexity can essentially yield favorable results. The choice of technique to utilize however, is often based on defect site presentation and operator comfort level. This presentation will focus on the use of ridge expansion, guided bone regeneration (GBR), and titanium mesh. Merits and indications of each technique will be discussed, and clinical cases will be presented that showcase the decision making process involved in treatment planning.

Digital Dentistry in the Management of Simple and Complex Cases: The Digital Intra-Scanner - Part 2
The advent of new technologies has enabled the utilization of new materials and equipment that facilitate the production of restorations with an accuracy that has, up to now, been difficult to obtain reliably. This lecture utilizes patient presentations to help analyze and highlight new systematic clinical protocols that have been developed to optimize the evolving knowledge in digital dentistry and materials. These protocols have allowed us to modify work flow and operational techniques to shorten lead times, while maintaining optimal accuracy. Advantages and disadvantages of the methods outlined will be evaluated and analyzed on the basis of existing literature and personal experience.

Advanced Immediate Implant Placement Strategies Including the Socket Shield (SS) Technique and its Complications
Immediate implant placement in the aesthetic zone has become a controversial topic with regards to the long term aesthetic demands that both the profession and our patients have placed on this treatment modality. Since the controversy broke a few years ago there have been a number of outstanding developments that have revolutionized the way we do immediate implant placement. Soft tissue augmentations using the tunnel technique as well as the socket whiled technique are 2 of these techniques which form the baseline of treatment in our clinic. This lecture will go through all the updated protocols of immediate implant placement supported by the literature as well as deal specifically with the finer details of the socket whiled technique including step by step photos and video of the technique. More importantly it will cover numerous complications that we have had to deal with over the last few years that we have been doing this technique.

Rehabilitation of the Extreme Atrophic Jaws
In this lecture you will learn several alternatives for the full arch rehabilitation of the jaws with different degrees of resorption. Several cases will be presented step-by-step with high-quality pictures for each technique explained. The main goals are to avoid complex regeneration procedures, to avoid zigomatic surgery and to still be able to perform immediate loading in the most compromised scenarios. All-on-Four technique, palatal approach technique, pterygoid implants and the most recent Subperiosteal Implants are some of the key-concepts presented.

Immediate Dental Implants; Are They a Good Option?
Immediate implant placement used to be a controversial subject, but nowadays we can obtain long-term high survival rates with this treatment option. Since surgical and prosthetic time is reduced and a great aesthetic result can be achieved, this therapy is often practiced. The aim of this presentation is to clarify which parameters and how can they influence a successful outcome in immediate implant placement. Several documented clinical cases and supporting literature will be presented to guide through diagnosis, treatment options and improvement of final outcome.
