Radiographic bone level changes of implant-supported restorations in edentulous and partially dentate patients: 5-year results.

Purpose: To evaluate and compare crestal bone level changes and peri-implant status of implant-supported reconstructions in edentulous and partially dentate patients after a minimum of 5 years of loading.

Materials And Methods: All patients who received a self-tapping implant with a microstructured surface during the years 2003 and 2004 at the Department of Prosthodontics, University of Bern, were included in this study. The implant restorations comprised fixed and removable prostheses for partially and completely edentulous patients.

Measurement of dental implant stability by resonance frequency analysis and damping capacity assessment: comparison of both techniques in a clinical trial.

Purpose: Two noninvasive methods to measure dental implant stability are damping capacity assessment (Periotest) and resonance frequency analysis (Osstell). The objective of the present study was to assess the correlation of these 2 techniques in clinical use.

Materials And Methods: Implant stability of 213 clinically stable loaded and unloaded 1-stage implants in 65 patients was measured in triplicate by means of resonance frequency analysis and Periotest.

Stability measurements of 1-stage implants in the edentulous mandible by means of resonance frequency analysis.

Objective: Resonance frequency analysis (RFA) is a method of measuring implant stability. However, little is known about RFA of implants with long loading periods. The objective of the present study was to determine standard implant stability quotients (ISQs) for clinical successfully osseointegrated 1-stage implants in the edentulous mandible.

[Anterior teeth esthetics with the SPI implant system].

Replacement of maxillary front teeth with a fixed, implant supported partial denture with a high laugh line is a demanding procedure. For an optimal esthetic result, no deficiency of bone or soft tissue is acceptable. Submerged implant healing has often been recommended for better predictability in esthetically demanding situations.

[The SPI implant system: clinical experience and one-year results].

The new Swiss implant system SPI became available three years ago and is used in combination with fixed and removable prosthetic reconstructions. In a pilot study the clinical procedures were evaluated and data of prosthetic complications of maintenance service were collected. 25 patients participated in the study with a total of 79 SPI implants during the time period from 2003-2004.

[Rehabilitation of an abraded occlusion with Procera-ZrO2 all-ceramic crowns. A case report].

The rehabilitation of a patient with advanced tooth wear by means of Procera ZrO2 ceramic crowns is described. A healthy, 60 year old patient complained about front teeth esthetics and impaired function due to reduced tooth height. He was aware of bruxism and wished full mouth rehabilitation.

Stability measurements of 1-stage implants in the maxilla by means of resonance frequency analysis: a pilot study.

Purpose: The objective of the present study was to determine standard Implant Stability Quotient (ISQ) values for apparently successfully osseointegrated 1-stage implants in the maxilla.

Materials And Methods: To measure implant stability, resonance frequency analysis (RFA) was performed in 35 patients (18 women, 17 men) with a total of 120 maxillary ITI implants. Based on the time interval between implant placement and measurements, the ISQ values of anterior and posterior implants were divided into subgroups: unloaded (n = 41), loaded < or = 12 months (n = 31), and loaded > 1 year (n = 48).
