- Objectives To determine the occurrence and clustering of complications in subjects restored with fixed implant-supported prostheses. Methods In the present retrospective case series, 241 subjects treated at one clinical centre and provided with 729 implants were included. A clinical and radiographic examination was performed after a mean follow-up period of 4.8 +/- 2.0 years. Additional information on occurrence of technical (chipping, loss of retention, fracture of components) and biological complications (marginal bone loss, implant loss) during follow-up was extracted from patient records. For each type of complication and complications overall, regression analyses were performed to identify potential risk factors. Cox regression analyses were used to evaluate time to event for implant loss and technical complications. Results In all, 30% of the 241 patients presented with at least one complication of technical and/or biological character during the follow-up period. Technical complications affected 19.5% of subjects, while 14.1% presented with marginal bone loss >2 mm. Implant loss occurred in 4.6% of subjects. While technical complications were noted already early during the maintenance period (<1200 days), implant loss typically occurred during a later phase. A small subgroup of subjects (7.9%) experienced more than one type of complication. Conclusions Complications occurred frequently and the most common type of complication was of technical character. Technical and biological complications occurred independently of each other.

- Objectives The aim of the present prospective study was to assess the risk for disease recurrence following surgical therapy of peri-implantitis. Material & Methods 73 patients (130 implants) treated surgically for peri-implantitis were examined at 1 and 5 years after therapy. The primary outcome was recurrence/progression of disease defined as any of the following events: (a) bone loss >1.0 mm, (b) surgical retreatment, (c) implant removal/loss after year 1. Patient- and implant-related parameters as well as 1-year outcomes were evaluated as potential predictors through multiple logistic regression analysis. Results 57 implants (44%) displayed recurrence/progression of peri-implantitis during follow-up. Among these, 27 implants were removed. Residual deep probing pocket depth (>= 6 mm; odds ratio 7.4; 95% confidence interval 2.8-19.3) and reduced marginal bone level (OR 1.4; 95%CI 1.1-1.7) at 1 year after surgery constituted risk factors for recurrence/progression of disease. Furthermore, implants with modified surfaces were at higher risk than implants with non-modified surfaces (OR 5.1; 95%CI 1.6-16.5). Conclusion Implants with (a) residual deep probing pocket depth, (b) reduced marginal bone level, or (c) modified surfaces following surgical therapy of peri-implantitis present with increased risk for recurrence/progression.

- Background: It is poorly understood how much additional dental care patients consume subsequent to implant therapy. The aim of the present study is to evaluate costs associated with implant-supported restorative therapy during the long-term follow-up. Material and Methods: Costs associated with preventive measures and complication-related procedures over a mean follow-up period of 8.2years were assessed in patient files of 514 Swedish subjects provided with implant-supported restorative therapy. The restorative therapy and each of the subsequent interventions were assigned a specific cost. Accumulated costs were calculated in three categories: (i) total cost including initial restorative therapy and complication-related interventions, (ii) cost of preventive measures alone, and (iii) cost of complication-related procedures alone. Potential differences by background variables were analyzed using growth curve models. Results: In the whole sample, costs during follow-up ranged from 878 € (95% CI 743; 1,014) for patients with single-tooth restoration(s) to 1,210 € (95% CI 1,091; 1,329) for subjects with full-jaw restoration(s). The majority of costs during follow-up originated from preventive measures (741 € 95% CI 716; 766). Among individuals receiving ≥1 intervention dealing with a complication (n=253), complication-related costs amounted to 557 € (95% CI 480; 634). For patients with full-jaw restorations, the corresponding amount was 769 € (95% CI 622; 916). Procedures related to peri-implantitis and technical complications resulted in costs similar to each other. Implant loss generated greater costs than any other type of complication. Conclusions: Costs related to implant-supported restorative therapy during follow-up were associated with the extent of initial therapy. The higher costs during follow-up noted in patients provided with full-jaw restorations were explained by complication-associated procedures. Implant loss was the most costly type of complication.

- Objectives The aim was to evaluate the overall occurrence and potential clustering of biological and technical complications in implant dentistry. Material and Methods 596 patients provided with implant-supported reconstructions were evaluated for the occurrence of (a) technical complications, (b) peri-implantitis and (c) implant loss during a period of 9 years. Time and type of event were scored, and potential risk factors were explored through parametric modelling of survival and hazards. Clustering of complications was assessed at the patient level, and patient satisfaction was evaluated by questionnaire completed at the 9-year examination. Results 42% of patients were affected by technical and/or biological complications during the 9-year observation period. Extent of therapy (Hazard Ratio 2.5: patients with partial jaw restorations; HR 3.9: patients with full jaw restorations) and a history of periodontitis (HR 1.6) were identified as risk factors. While technical complications occurred mostly as isolated events, 41% of subjects identified with peri-implantitis and 52% of subjects with implant loss also presented with other complications. The hazard for technical complications and implant loss peaked at 0.7 years and 0.2 years, respectively, while the hazard for peri-implantitis was consistent throughout the observation period. The overall proportion of satisfied patients at 9 years was high (95%), and only minor differences between individuals with and without complications were noted. Conclusions Complications following implant-supported restorative therapy were common findings. Extent of therapy and periodontitis were identified as risk factors. While technical complications occurred in an isolated pattern, peri-implantitis and implant loss demonstrated clustering with other types of complications.

- The aim of the present study was to evaluate whether clinical findings at implant sites are relevant as screening tests for a history of marginal bone loss.427 patients provided with implant-supported reconstructions 9 years earlier were evaluated clinically (probing pocket depth (PPD), bleeding on probing (BoP)) and radiographically. A history of bone loss was confirmed through baseline documentation. Diagnostic accuracy was evaluated through Receiver Operating Characteristic curves and multi-level regression analyses. Results were expressed as sensitivity/specificity, area under the curve and odds ratios.While the sensitivity of PPD in regard to bone loss was low, specificity was generally high. Multi-level modelling revealed that each additional millimeter of PPD corresponded to an additional bone loss of 0.30 mm (95%CI 0.27; 0.33). The sensitivity of BOP in regard to bone loss >2 mm was 80.9% (95%CI 73.9; 86.7), while the specificity was 42.2% (95%CI 39.6; 44.8).Clinical parameters at implant sites obtained at a single time point were associated with a history of marginal bone loss. While BoP demonstrated a high level of sensitivity, the sensitivity of PPD was generally low. The present data suggest that BoP is a relevant screening test for history of bone loss.

Forskningsöversikt (refereegranskat)abstract
- Peri-implantitis is a plaque-associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri-implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri-implantitis has become a major disease burden in dentistry. An understanding of the diagnosis, etiology and pathogenesis, epidemiology, and treatment of peri-implantitis must be a central component in undergraduate and postgraduate training programs in dentistry. In view of the strong role of European research in periodontology and implant dentistry, the focus of this review was to address peri-implantitis from a European perspective. One component of the work was to summarize new and reliable data on patients with dental implants to underpin the relevance of peri-implantitis from a population perspective. The nature of the peri-implantitis lesion was evaluated through results presented in preclinical models and evaluations of human biopsy material together with an appraisal of the microbiological characteristics. An overview of strategies and outcomes presented in clinical studies on nonsurgical and surgical treatment of peri-implantitis is discussed with a particular focus on end points of therapy and recommendations presented in the S3 level Clinical Practice Guideline for the prevention and treatment of peri-implant diseases.

- Numerous surgical techniques for root coverage have been suggested with different degrees of success, as assessed by the proportion of complete root coverage. Mandibular incisors, teeth with a high frequency of gingival recession defects (GRDs), were associated with the least favorable outcomes due to unfavorable anatomical conditions. In the present series of three cases, a modified version of the free gingival graft technique for the purpose of root coverage at mandibular incisors is illustrated. The purpose of the modification of the original technique was to achieve improved blood supply from the recipient site to the graft, with the ultimate aim of enhancing predictability and outcomes of the procedure. In all included cases, complete or almost complete root coverage was achieved at challenging GRDs in the mandibular incisor area.

- BackgroundThe aim of this study was to evaluate clinical and patient-reported outcomes following surgical root coverage at RT1 gingival recession defects at mandibular incisors, using either a conventional free gingival graft (FGG) or a modified FGG (ModFGG). MethodsTotal of 30 patients with RT1 gingival recessions at mandibular incisors were enrolled and randomly allocated to either a control (FGG) or test group (ModFGG). Evaluations of clinical changes (recession depth, height of keratinized tissue) and patient satisfaction were performed over a follow-up period of 12 months. Post-surgical changes of keratinized tissue height (shrinkage) were assessed from 1 month and onward. ResultsModFGG resulted in more pronounced root coverage at 1 year compared to FGG (91.8% vs. 60.7%, p < 0.001). Height of keratinized tissue was improved by 4.2 and 2.2 mm (p < 0.001), respectively, with significantly less shrinkage in ModFGG. Post-surgical morbidity was significantly lower for ModFGG at 2 weeks and patient satisfaction was significantly higher 12 months after treatment (9.1 vs. 5.4; p < 0.001). ConclusionsModFGG represents a valid approach for the management of RT1 recession defects at mandibular incisors. The technique is superior to traditional FGG in terms of root coverage, the gain of keratinized tissue height, and patient satisfaction.

- To examine progression of experimental peri-implantitis around different implants placed in augmented and pristine sites. M&M: 6 Labrador dogs were used. 3months after tooth extraction, 4 implants with different surface modifications were installed on each side of the mandible. A standard osteotomy was applied on one side, while on the contralateral side the osteotomy was modified, resulting in a gap between the implant and the bone wall. The gap was filled with a bone substitute and covered by a resorbable membrane. 3months after implant installation, implants were exposed and healing abutments were connected. 2months later, oral hygiene procedures were abandoned and a cotton ligature was placed in a submarginal position around the neck of all implants and kept in place for 4weeks. Following ligature removal, plaque formation continued for 6months (spontaneous progression period). Radiographs were obtained throughout the experiment and biopsies were collected and prepared for histological evaluation at the end of the spontaneous progression period.Differences in bone loss during the spontaneous progression period between pristine and augmented sites were small. The size and vertical dimension of the peri-implantitis lesion were larger at augmented than at pristine sites. Implants with non-modified surfaces exhibited smaller amounts of bone loss and smaller dimensions of peri-implantitis lesions than implants with modified surfaces.Small differences in spontaneous progression of peri-implantitis were detected between pristine and augmented sites. Implants with modified surfaces exhibited more bone loss and larger lesions than implants with non-modified surfaces, irrespective of the type of surrounding bone.
