Qualitative studies of patients' perceptions of loss of teeth, the edentulous state and prosthetic rehabilitation: a systematic review with meta-synthesis.

Objective: To conduct a systematic review and meta-synthesis of qualitative studies addressing patients' perceptions of loss of teeth, edentulism and oral rehabilitation.

Background: Qualitative studies can complement quantitative studies by achieving deep understanding of patients' subjective experiences of losing teeth and coping with edentulism. They can also explore the perception that the benefits of prosthetic rehabilitation extend far beyond primary clinical treatment goals of restoration of oral function.

Treatment of adult patients with partial edentulism: a systematic review.

Purpose: The purpose of this systematic review was to identify and critically appraise published studies of treatment methods used in general practice to rehabilitate adult patients with single tooth loss or partial edentulism, with special emphasis on outcomes reported after at least 5 years of follow-up.

Materials And Methods: Three databases were searched using specified indexing terms. Publications were included if the study design, research questions, and sample size satisfied pre-established criteria.

Treatment of adult patients with edentulous arches: a systematic review.

Purpose: This study aimed to evaluate the outcomes of treatment methods used to rehabilitate adult patients with maxillary and/or mandibular edentulism after at least 5 years of follow-up. The risks, adverse effects, and cost effectiveness of these methods were also evaluated.

Materials And Methods: Three databases as well as the reference lists of included publications were searched using specified indexing terms.

Materials And Methods: Three databases were searched using specified indexing terms. The reference lists of relevant publications were also searched manually.

Outcome of Brånemark Novum implant treatment in edentulous mandibles: a retrospective 5-year follow-up study.

Background: A gradual progression from a two-stage surgical technique to a one-stage and even immediate surgical protocol has occurred during the last decade with most oral implant systems. However, every new approach must obviously be reported individually, with long-term results, in order to assess whether the changes have any real patient value.

Purpose: The aim of the present report was to retrospectively review the 5-year outcome of patients treated with the Brånemark Novum (Nobel Biocare AB, Göteborg, Sweden) protocol.

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.

Outcome of oral implant treatment in partially edentulous jaws followed 20 years in clinical function.

Background: Most long-term follow-up studies of implants in partially edentulous jaws present their outcomes as mean values of implant survival and follow-up time, and few address the fate of the remaining teeth.

Purpose: The aim of this study was to investigate the results of oral implant treatment in partially edentulous jaws after 20 years, and simultaneously to assess what happens to teeth present at the time of implant placement.

Materials And Methods: Seventeen partially edentulous patients, of 27 originally treated individuals, were retrospectively reviewed after receiving implants from 1983 to 1985.

Tissue alterations at implant-supported single-tooth replacements: a 1-year prospective clinical study.

Objectives: The aim of this prospective study was to evaluate dimensional alterations of the peri-implant tissues at single-tooth restorations from the time of implant placement to 1-year post-loading.

Material And Methods: Eleven patients, aged 18-36 years, subjected to single-tooth replacements with implant-supported restorations (Brånemark implant system) in the maxillary anterior region were included in the analysis. The implant installation was performed as a two-stage procedure with a 6-month healing interval.

Single implants and buccal bone grafts in the anterior maxilla: measurements of buccal crestal contours in a 6-year prospective clinical study.

Aim: The aim of the present study was to assess the prevalence of subjects with progressive bone loss at implants with a function time of at least 5 years.

Material And Methods: Radiographs of 1346 patients who had attended annual follow-up visits at the Brånemark Clinic, Public Dental Services, Gothenburg, Sweden were retrieved. Six hundred and sixty-two subjects fulfilled the inclusion criteria.

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.

Failure patterns of four osseointegrated oral implant systems.

The aim of this metanalysis was to investigate possible differences in failure patterns among four different osseointegrated oral implant systems. Only systems with a supposed scientific validation, based on long-term follow-up studies, were selected for this analysis, i.e.

Microbiologic diagnostics at titanium implants.

Background: The microbiota found at periimplant lesions have been shown to contain putative periodontal pathogens as well as opportunistic species such as Staphylococcus spp, enterics, and Candida spp. Therefore, a microbiologic diagnosis may be of value as guidance before treatment of such lesions.

Purpose: The aim of this study was to evaluate the prevalence of some putative pathogens associated with long-term followed-up cases using two different microbiologic procedures.

Histopathological observations of human periimplantitis lesions.

Objective: The aim of the present study was to analyze some characteristics of advanced and progressive periimplantitis lesions in man.

Material And Methods: Soft tissue biopsies were obtained from 12 implants in six patients. The implants had been in function between 4 and 21 years and were, with one exception, located in the maxilla.

Measurements of buccal tissue volumes at single-implant restorations after local bone grafting in maxillas: a 3-year clinical prospective study case series.

Purpose: The purpose of this study was to measure changes in buccal and proximal tissue volumes after local bone grafting and single-implant treatment.

Materials And Methods: Ten patients were provided with buccal bone grafts 6 months prior to implant treatment in central upper incisor regions. Following a healing time of 6 months, abutments and single-implant crowns were installed and followed up for 2 years.

Peri-implant bone alterations in relation to inter-unit distances. A 3-year retrospective study.

The aim of the present retrospective study was to evaluate longitudinal alterations in radiographic bone topography at proximal sites of three-unit implant-supported fixed partial prostheses during the first 3 years after bridge installation, in relation to vertical and horizontal inter-unit distances. The subjects were partially dentate patients who had received implant-supported fixed partial prostheses during the year 1995 at the Brånemark Clinic, Göteborg, Sweden. For inclusion in the study, the patient had to have a three-unit bridge construction supported by three implants in the posterior area of the jaw.

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.

Statistical outcome of random versus selected withdrawal of dental implants.

Purpose: When performing clinical trials, missing data from withdrawn patients should be evaluated differently, depending on the reason for the withdrawal of the patients. The question is, if a certain type of patient drops out, will that affect the result? Could a randomly selected sample of a study population be used for analyses instead of evaluating each and every patient? The purpose of this study was to answer these questions.

Materials And Methods: Detailed information on 1,738 implants in 487 patients was pooled together in a new database and used for statistical evaluations.

Outcome of implant therapy in relation to experienced loss of periodontal bone support: a retrospective 5- year study.

Purpose: The aim of this retrospective study was to analyse bone level alterations over a 5-year period at implants in the maxillary posterior segments in patients with varying experience of periodontal bone loss in the natural dentition before implant placement.

Materials And Methods: 97 partially dentate patients with a total of 346 Brånemark oral implants in the maxillary posterior segments were included. By assessing the degree of radiographic marginal bone loss in the remaining natural dentition at time of the implant therapy, an age-related bone loss score (ArB-score) was calculated for description of the patient's experience of periodontal destruction.

Orthodontic aspects of the use of oral implants in adolescents: a 10-year follow-up study.

The aim of the present study was to evaluate the long-term effect of implants installed in different dental areas in adolescents. The sample consisted of 18 subjects with missing teeth (congenital absence or trauma). The patients were of different chronological ages (between 13 and 17 years) and of different skeletal maturation.

Five-year evaluation of implants placed at extraction and with dehiscences and fenestration defects augmented with ePTFE membranes: results from a prospective multicenter study.

Background: Barrier membranes have been used to promote bone ingrowth on implants with dehiscences and fenestrations. Membranes also have been used to protect defects adjacent to implants placed at the time of extraction. The concept of guided bone regeneration relates to preferentially allowing cells from bone to migrate into various defects while excluding fibrous tissue and epithelium.
