摘要:

There has never been any resolution to the possible problems (such as, natural root intrusion) associated with combining implants and natural tooth/root abutments in the same partially-edentulous arch. Lecturers, for the most part, anecdotally advocate “breaking-up” the prosthetic suprastructure so as not to include both entities as anchorage for the porcelain-fused-to-metal suprastructure. In your opinion, is this separation necessary? And, is this separation always possible? If not, what do you suggest?

摘要:

The maxilla is the more difficult arch to restore with endosseous dental implants because of hurdles such as low bone density, narrow buccopalatal width, minimal bone height, and proximity to the maxillary sinus. In this article, a technique to resolve all of these problems using a short, tapered, porous-surfaced implant and a placement protocol using hand osteotomes rather than surgical burs is presented.

摘要:

Today, prognathism in the partially or completely edentulous jaw can be treated with endosteal implants and fixed prostheses. The preferred procedure uses basal osseointegration. If the distribution of available bone is favorable, the prosthodontic suprastructures can be loaded early, taking the various phases of bone regeneration into account. Invasive surgical interventions, specifically iliac crest transplants, are rarely indicated and can be avoided in most cases. Patients are able to return to their everyday lives within a few days.

摘要:

Failing implants can be successfully treated by surgical procedures that use either bone fillers or membranes combined with an antimicrobial treatment. In this report, we present a case of failing implants with the corresponding treatment and results of 8 years of follow-up.

摘要:

The three-dimensional guidance system for implant insertion is a technique for placing a radiopaque vertical orientation pin over the crest of the alveolar ridge on the stone cast during fabrication of the radiographic guide. The cross-sectional and panoramic reformatted images were reproduced on a Polaroid or 35-mm print. The true vertical orientation pin facilitates (1) identification and the exact planned location of each implant in the reformatted images of the CT scan, (2) establishment of the internal starting point for the osteotomy on a photographic print, (3) optimum implant orientation, and (4) measurement of the angulation between the true vertical orientation line and optimum implant orientation. With the aid of a newly developed dual-axes base and transfer of the internal starting point of each implant to the stone cast, the buccolingual and mesiodistal implant inclinations for each implant were transferred to a surgical guide in the form of surgical steel drill guide tubes. The resulting pilot osteotomy transfers to the alveolar bone the exact starting point and the buccolingual and mesiodistal inclination for each implant. The technique provides a three-dimensional guidance system for implant insertion that is extremely accurate and yet practical.

摘要:

Dental implant failure has led to continuous innovations of various implant systems and to different interceptive treatment modalities. These concerns have also led to selection of implant designs that best suit the various types of bone. A checklist has been created to facilitate collection of data on the different factors associated with dental implant failure. The data gathered from this list are the basis of a multinational statistical analysis. This analysis will provide accurate information about the percentage of each element causing implant failure. Different causes of failure, such as host factors, surgical placement, and improper implant selection, were reviewed in Part I of this two-part series. This article discusses failure categories in terms of etiology, failure mode, failure type, failure origin, failure timing, responsible personnel, and different tissue types.

摘要:

This two-part series focuses on localized ridge augmentation using block autografts from the symphysis and the ramus buccal shelf for posterior maxillary (part I) and mandibular (part II) reconstruction. The various aspects of the surgical technique necessary for predictable results and minimal morbidity are discussed in detail. Emphasis is placed on staging, incision design, and recipient site preparation.
