A study on variances in multivariate analyses of oral implant outcome.

Background: Elaborate studies have shown that interdependency exists between implants being placed in the same patient/jaw. Therefore, interdependency ought to be an important aspect to address, whenever performing statistical analyses of oral implant outcomes. A Jackknife method could be an option when conducting statistical evaluations of oral implant failure prognoses.

Removing dentine caries in deciduous teeth with Carisolv: a randomised, controlled, prospective study with six-month follow-up, comparing chemomechanical treatment with drilling.

Dental fear is often associated with experience of pain, unpleasant sounds and uncomfortable vibrations caused by dental drills. Therefore patients welcome alternative, less painful excavating methods such as lasers, sandblasters and chemomechanical systems. The aim of this study was to compare a chemomechanical caries removal system (Carisolv) to traditional drilling with regard to patient acceptance and time consumption as well as the six-month success rate of fillings.

Evaluation of patient and implant characteristics as potential prognostic factors for oral implant failures.

Purpose: The purpose of this study was to evaluate patient, implant, and treatment characteristics to identify possible prognostic factors for implant failure.

Materials And Methods: Out of a database with different dental implant treatment protocols, a research database of 1 randomly selected implant per patient was created. The database consisted of 487 implants.

Some soft tissue characteristics at implant abutments with different surface topography. A study in humans.

Background: : If an implant with a rough surface is exposed to the oral cavity, it may accumulate greater amounts of plaque than a smooth surface, which may lead to severe problems with mucositis and peri-implantitis. The purpose of the present paper was to investigate the early inflammatory response to mucosa-penetrating abutments prepared with varying surface roughness.

Methods: : Nine patients had all five of their original abutments exchanged to test abutments for a 4-week period.

The influence of Carisolv on enamel and dentine surface topography.

The purpose of the present study was to investigate the surface topography of healthy enamel and dentine before and after application of a new chemomechanical system for caries removal, Carisolv. The same surfaces were investigated with respect to the influence of phosphoric acid, plus carious dentine after removal with either Carisolv or burrs. One-hundred freshly extracted teeth were used.

A 5-year multicenter study on implant-supported single crown restorations.

In this multicenter prospective study, the results achieved with the use of Brånemark implants for single tooth replacement were evaluated. The overall cumulative success rate was 95.9% for implants and 91.

Implant survival rates in partially edentulous patients: a 3-year prospective multicenter study.

Purpose: This multicenter investigation is an interim 3-year survival report of a 5-year prospective study using Brånemark osseointegrated implants in partially edentulous patients.

Materials And Methods: Previously defined patient characteristics and clinical parameters were related to implant survival using lifetable analysis.

Results: Three years after prosthesis insertion, 460 implants placed in 139 patients remained in the study.

MkII--a modified self-tapping Brånemark implant: 3-year results of a controlled prospective pilot study.

A modified self-tapping implant (MkII) with improved cutting characteristics has been designed for use in both maxillae and mandibles. Four sequential studies were conducted to evaluate the outcome of the MkII implant compared to the standard implant. The results presented here are from the extended pilot study that has been conducted as an intra-individual study of 103 patients; ie, each patient received both test (MkII) and control (standard Brånemark System) implants.

The use of e-PTFE barrier membranes for bone promotion around titanium implants placed into extraction sockets: a prospective multicenter study.

This multicenter study was conducted to determine the predictability for implants placed into immediate extraction sockets and augmented with e-PTFE barrier membranes. Forty-nine implants were placed in immediate extraction sockets. Initial and final defect measurements and the number of threads exposed were compared.
