X-ray microtomographic evaluation of the influence of two preparation types on marginal fit of CAD/CAM alumina copings: a pilot study.

This study evaluated the influence of two preparation types on the marginal fit of computer-aided design/computer-assisted manufacture (CAD/CAM) alumina copings. Two subgroups of four alumina copings each were fabricated using alumina master dies with either a chamfer or 90-degree shoulder preparation. Copings were scanned with an x-ray microtomographic scanner, and marginal fit was evaluated.

Prosthodontic complications with implant overdentures: a systematic literature review.

Purpose: Problems associated with a complete denture, such as lack of stability and retention, can be solved with the use of implant-retained or implant-supported overdentures. However, controversy exists as to the anchorage system used and indications for both the maxilla and mandible. The purpose of this review was to identify the prosthetic complications associated with the different attachment mechanisms used for implant-supported or implant-retained overdentures.

Treatment planning of a partially edentulous case.

In the present article, the advantages and disadvantages of three treatment options (clasp-retained removable partial dentures, tooth-supported telescopic retained partial dentures, and implant-supported/retained prostheses) are discussed. Furthermore the case of a 44-year-old woman with shortened and interrupted dental arches is presented. The treatment selected for the case is revealed, and the rationale governing the decision is discussed.

Are ceramic implants a viable alternative to titanium implants? A systematic literature review.

Aim: The aim of this systematic review was to screen the literature in order to locate animal and clinical data on bone-implant contact (BIC) and clinical survival/success that would help to answer the question 'Are ceramic implants a viable alternative to titanium implants?'

Material And Methods: A literature search was performed in the following databases: (1) the Cochrane Oral Health Group's Trials Register, (2) the Cochrane Central Register of Controlled Trials (CENTRAL), (3) MEDLINE (Ovid), and (4) PubMed. To evaluate biocompatibility, animal investigations were scrutinized regarding the amount of BIC and to assess implant longevity clinical data were evaluated.

Results: The PubMed search yielded 349 titles and the Cochrane/MEDLINE search yielded 881 titles.

Relationship between interleukin-1 genotype and peri-implantitis: a literature review.

Endosseous implants present high survival rates within a 10-year observation time; however, implant failure and biologic complications are not completely avoidable. Although specific bacteria, dental plaque, and environmental factors are associated with peri-implant disease, there are currently no reliable predictors of peri-implantitis occurrence and severity. Disagreement about which clinical measures of peri-implant health are of diagnostic value continues because of the complexity of the disease process.

Fracture strength of zirconia implants after artificial aging.

Background: Zirconia (ZrO(2)) might be an alternative material to titanium (Ti) for dental implant fabrication. However, no data are available on the fracture strength of one-piece ZrO(2) oral implants.

Purpose: The objective of this study was to evaluate the fracture strength of ZrO(2) implants after exposure to the artificial mouth.
