- Objectives: To test whether or not transmucosal healing at two-piece implants is as successful as submerged placement regarding crestal bone levels and patient satisfaction. Material and methods: Adults requiring implants in the anterior maxilla or mandible in regions 21-25, 11-15, 31-35 or 41-45 (WHO) were recruited for this randomized, controlled multi-center clinical trial of a 5-year duration. Randomization was performed at implantation allowing for either submerged or transmucosal healing. Final reconstructions were seated 6 months after implantation. Radiographic interproximal crestal bone levels and peri-implant soft tissue parameters were measured at implant placement (IP) (baseline), 6 and 12 months. Patient satisfaction was assessed by a questionnaire. A two-sided t-test (80% power, significance level α=0.05) was performed on bone-level changes at 6 and 12 months. Results: One hundred and twenty-seven subjects were included in the 12-month analysis (submerged [S]: 52.5%, transmucosal [TM]: 47.2%). From IP to 6 months, the change in the crestal bone level was -0.32mm (P<0.001) for the S group and -0.29mm (P<0.001) for the TM group. From IP to 12 months, bone-level changes were statistically significant in both groups (S -0.47 mm, P<0.001; TM -0.48mm, P<0.001). The mean differences of change in the bone levels between the two groups were not statistically significant at either time point, indicating the equivalence of both procedures. For both groups, very good results were obtained for soft tissue parameters and for patient satisfaction. Conclusions: Transmucosal healing of two-piece implants is as successful as the submerged healing mode with respect to tissue integration and patient satisfaction within the first 12 months after IP. © 2011 John Wiley & Sons A/S.

Forskningsöversikt (refereegranskat)abstract
- Purpose: To identify and critically appraise scientific publications evaluating the possible effect of implant design on treatment outcomes in the rehabilitation of patients with a fully edentulous maxilla. Materials and Methods: Scientific reports were sought in three electronic bibliographic databases, combined with searches for meeting abstracts, and in the grey literature. English, German, or Scandinavian scientific publications on prospective or retrospective longitudinal studies with effects of an implant design or feature on the treatment outcomes were eligible. Minimum requirement for inclusion was at least 10 study participants who were followed up for at least 2 years after implant loading. The PRISMA guidelines were followed for selecting data to extract from the individual studies. These were characteristics of the individual studies, risk of bias within individual studies, and the results of individual studies. Three editorial teams independently identified and extracted the data. Results: The search resulted in 998 primary studies, of which 525 met the inclusion criteria and were read in full text. Of these, 105 studies were included in qualitative syntheses. Seventeen studies were designed with an objective to assess effects of implant design or feature on outcomes, 23 studies described tilted implants to enable placement of longer implants, 30 studies reported effects of implants placed in zygomatic bone with or without additional alveolar implants, and 9 studies reported effects of implants placed in pterygoid bone or other bony buttresses with or without additional alveolar implants. Sixteen articles reported bone augmentation with simultaneous or delayed implant placement in patients with a predominantly Cawood-Howell bone class V and VI maxilla. Ten papers reported effects of implant design on outcomes, despite the lack of an a priori stated objective to assess a particular implant design or feature. There is a lack of compelling data to state that one particular implant system or design feature stands out amidst others, when applied to restoring the fully edentulous maxilla with implant-retained prostheses. Conclusion: This systematic review failed to identify compelling evidence to conclude that any particular implant or feature affects the treatment outcome in patients with a fully edentulous maxilla.

- Aim: The aim was to assess the potential trends in Periodontology and Periodontics in Europe that might be anticipated by the year 2025, using the Delphi method. Material and Methods: The expert opinion of 120 experts was sought through the use of an open-ended questionnaire, developed by an advisory group, containing 40 questions concerning the various trends in periodontology Results: The experts (113 responders) expect a stabilization of the prevalence of periodontitis, both for the chronic as well as the aggressive cases, but an increase in implant-related diseases up to the year 2025. Concurrently, the importance of implants is seen to be increasing. They foresee an increased demand for postgraduate periodontology and implantology training. This is mirrored in an increase in publications for implant dentistry and increase in demand and need for training. Concerning the patients, better-informed individuals seeking more routine checkups are expected Conclusion: A continued need for specialized periodontists, but also well trained dental practitioners is foreseen for next decade in Europe. Apart from periodontology they will be increasingly exposed to and trained in implant dentistry

- Department of Cariology and Endodontology, College of Dental Sciences, University Medical Centre Nijmegen, The Netherlands. a.plasschaert@dent.umcn.nl This paper presents a proposed curriculum structure and system of European Credit Transfer (ECTS) for undergraduate dental schools throughout Europe. It is the result of the work of a Taskforce ('Taskforce II'), appointed by DentEd, a thematic network of European dental schools and the Association for Dental Education in Europe (ADEE). There has been pan-European discussion of the document in draft stages (it was distributed to 200 dental schools) and following amendment, it was agreed formally at the National Assembly of ADEE in Athens, Greece, in September 2005. The main elements of the paper relate to: (i) a description of the framework proposed with relevance to the Bologna recommendations and common directive on recognition for professional qualifications as they apply to Dentistry; (ii) the structure of an undergraduate dental curriculum; (iii) student exchange and ECTS. In addition, the paper presents a series of requirements, guidelines and recommendations for action. ADEE expects that the 'requirements' proposed will be followed by dental schools in Europe, whilst the 'guidelines' and 'recommendations' also provided are open to local interpretation. The paper is also published on the ADEE website.

- The aim of the present study was to evaluate the diagnostic accuracy of clinical and radiographic evaluations made at a single time point during follow-up in identifying (i) a history of peri-implant bone loss and (ii) the presence of peri-implantitis.427 patients provided with implant-supported reconstructions 9 years earlier were evaluated clinically by Probing Pocket Depth, Bleeding or Suppuration on Probing (PPD, BoP & SoP) and radiographically. Bone levels were assessed relative to the most coronal point of the intra-osseous part of the implant. A history of bone loss and diagnosis of peri-implantitis was confirmed through baseline documentation (direct evidence). Diagnostic accuracy of radiographic bone levels at 9 years and clinical findings (indirect evidence/secondary case definition) in identifying a history of bone loss and peri-implantitis were evaluated through correlation and multi-level regression analyses as well as Receiver Operating Characteristic curves. Results were expressed as sensitivity/specificity and area under the curve (AUC).Bone levels observed at 9 years were highly accurate in identifying pronounced bone loss (>2 mm; AUC=0.96; 95%CI 0.95-0.98). In the absence of baseline documentation, a secondary case definition based on the presence of BoP/SoP & bone level ≥1 mm (indirect evidence) provided the overall best diagnostic accuracy (AUC=0.80; 95%CI 0.77-0.82) in identifying peri-implantitis cases (direct evidence: BoP/SoP & bone loss >0.5 mm). Moderate/severe peri-implantitis (BoP/SoP & bone loss >2 mm) was most accurately identified by the combination of BoP/SoP & bone level ≥2 mm (AUC=0.93; 95%CI 0.91-0.96). Sensitivity of the secondary case definition suggested by the 2017 World Workshop of Periodontology (WWP) (BoP/SoP ≥1 site & bone level ≥3 mm & PPD ≥6 mm) was low.The present results underline the importance of baseline documentation for the correct diagnosis of peri-implantitis, especially in its early/incipient forms. The secondary case definition of peri-implantitis suggested at the 2017 WWP demonstrated a high level of specificity but low sensitivity. Moderate/severe peri-implantitis was most accurately identified by the combination of BoP/SoP & bone level ≥2 mm.

- Abstract Aim: The primary objective of this study was to determine the association between the size of the void established by using two different implant configurations and the amount of buccal/palatal bone loss that occurred during 16 weeks of healing following their installation into extraction sockets. Material and methods: The clinical trial was designed as a prospective, randomized-controlled parallel-group multicenter study. Adults in need of one or more implants replacing teeth to be removed in the maxilla within the region 15-25 were recruited. Following tooth extraction, the site was randomly allocated to receive either a cylindrical (group A) or a tapered implant (group B). After implant installation, a series of measurements were made to determine the dimension of the ridge and the void between the implant and the extraction socket. These measurements were repeated at the re-entry procedure after 16 weeks. Results: The study demonstrated that the removal of single teeth and the immediate placement of an implant resulted in marked alterations of the dimension of the buccal ridge (43% and 30%) and the horizontal (80-63%) as well as the vertical (69-65%) gap between the implant and the bone walls. Although the dimensional changes were not significantly different between the two-implant configurations, both the horizontal and the vertical gap changes were greater in group A than in group B. Conclusions: Implant placement into extraction sockets will result in significant bone reduction of the alveolar ridge.

- BACKGROUND: Two systematic reviews have evaluated the quality of research and reporting of observational studies investigating the prevalence of, the incidence of and the risk factors for peri-implant diseases and of experimental clinical studies evaluating the efficacy of preventive and therapeutic interventions.MATERIALS AND METHODS: For the improvement of the quality of reporting for both observational and experimental studies, the STROBE and the Modified CONSORT recommendations were encouraged.RESULTS: To improve the quality of research in peri-implant diseases, the following were recommended: the use of unequivocal case definitions; the expression of outcomes at the subject rather than the implant level; the implementation of study validation tools; the reporting of potential sources of bias; and the use of appropriate statistical methods.CONCLUSIONS: In observational studies, case definitions for peri-implantitis were agreed. For risk factor determination, the progressive use of cross-sectional and case-control studies (univariate analyses), to prospective cohorts (multilevel modelling for confounding), and ultimately to intervention studies were recommended. For preventive and interventional studies of peri-implant disease management, parallel arm RCTs of at least 6-months were encouraged. For studies of non-surgical and surgical management of peri-implantitis, the use of a composite therapeutic end point was advocated. The development of standard control therapies was deemed essential.
