Journal article (peer-reviewed)abstract
- Aim: To examine the existing evidence in identifying risk indicators in the etiology of peri-implantitis. Material and methods: A literature search was performed in MEDLINE via PubMed database of the US National Library of Medicine, for articles published until October 2014 using Medical Subject Heading search terms + free text terms and in different combinations. Results: The microbiota associated with peri-implantitis is complex, demonstrating differences and similarities to the one seen at periodontitis sites. Plaque accumulation at dental implants triggers the inflammatory response leading to peri-implant mucositis/peri-implantitis. Individuals with a history of periodontal disease and smokers have an increased risk of developing peri-implantitis. There is some evidence to support the role of genetic polymorphism, diabetes, and excess cement as risk indicators for the development of peri-implantitis. There is also evidence to support that individuals on regular maintenance are less likely to develop peri-implantitis and that successful treatment of periodontitis prior to implant placement lowers the risk of peri-implantitis. Conclusions: Plaque accumulation at implants will result in the development of an inflammation at implants. A history of periodontal disease, smoking, excess cement, and lack of supportive therapy should be considered as risk indicators for the development of peri-implantitis.

Journal article (other academic/artistic)abstract
- Background: The dynamics of soft and hard tissue volume maintenance following the placement of immediate-loaded implants in aesthetic areas remains unclear in literature. Aim/Hypothesis: To present a method to evaluate by clinical (photography) and radiographic bi- and tri-dimensional means the alterations in soft and hard tissues following immediate implant placement and loading in the anterior maxilla. Material and methods: Ten patients, treated with immediateloaded implants in the maxillary central or lateral incisor, were evaluated in this study. Clinical parameters (distance from the tip of the crown to the interdental papilla – P; distance from the top of the crown to the gingiva – C; keratinized mucosa height – K) were evaluated in standardized pictures taken immediately after (baseline), and 1, 3, and 6 months after provisional implant-supported single crown placement. Bi-dimensional radiographic parameters (distance from the top of the implant to the first bone-to-implant contact – IT-FBIC; distance from the bone crest to the first bone-to-implant contact – BC-FBIC; lateral bone lost at the implant neck – LBL) were evaluated from standardized digital periapical radiographies acquired at the same time points, or from CBCT images (buccal bone wall thickness, measured at the top, the midpoint and the apex of the implant – TT, MT, and AT, respectively) acquired at baseline and 6 months after surgery. The volume of the buccal bone wall covering the central millimeter of the implant (BV) was also assessed in the CBCT images. Comparison among multiple periods of observation were performed using repeated-measures ANOVA followed by Tukey post-hoc test, while two-period based comparison were made using paired t-test. Results: The variation for all clinical (photographic), bi- and tri-dimensional parameters assessed was non-statistically significant. Mean P was 5.55 1 mm, considering all time periods, while C and K were 9.2 1.2 and 5.3 1.6 mm, respectively. Mean IT-FBIC was 1.3 0.8 mm, considering all time periods, whilst BC-FBIC and LBL were 3.9 1.1 and 0.3 0.1 mm, respectively. There was a 94% maintenance of BV. Conclusions and clinical implications: Assessed parameters showed good clinical, bi- and tri-dimensional radiographic stability of soft and hard tissues for implants immediately placed and loaded in aesthetic areas.

- OBJECTIVES: The task of this working group was to update the knowledge about the use of drugs and biologicals affecting healing of soft tissue and bone during implant treatment or procedures associated with it. Moreover, the impact of titanium particles and biocorrosion on complications and implant survival has been analysed. MATERIALS AND METHODS: The literature in the areas of interest (platelet concentrates, antiresorptive drugs as well as implant-host interaction) was screened using systematic reviews for the former two areas, whereas a narrative critical review was performed for the latter topic. Two manuscripts on platelet concentrates, one manuscript on antiresorptive drugs and one manuscript on the effects of biocorrosion, were presented for group analysis with subsequent discussion in the plenum and final consensus approval. RESULTS: Results and conclusions of the individual reviews of the three topics are presented in the respective papers. Conclusions of the group on strengths and weaknesses of available evidence as well as consensus statements and directions for further research are provided in this study. The following papers were subject to group discussions and formed the basis for the consensus statements: Stahli A, Strauss FJ, Gruber R.

Long-term stability of peri-implant tissues after bone or soft tissue augmentation : Effect of zirconia or titanium abutments on peri-implant soft tissues: Summary and consensus statements. The 4th EAO Consensus Conference 2015
- 2015

In: Clinical Oral Implants Research. - : John Wiley & Sons. - 0905-7161 .- 1600-0501. ; 26, s. 148-152

Journal article (peer-reviewed)abstract
- Introduction: Several surgical techniques and prosthetic devices have been developed in the last decades, aiming to improve aesthetic, hygienic and functional outcomes that may affect the peri-implant tissues, such as procedures of bone and soft tissue augmentation and the use of custom-made abutments of titanium and zirconium. Materials and methods: Three systematic reviews, based on randomized clinical trials and prospective studies covering the above reported topics were analysed, and the detected evidence was exposed to interactive experts' discussion during the group's and general assembly's meetings of the 4th EAO Consensus Conference. The results are reported using the following abbreviations: ST: short-term evidence, M-T: medium-term evidence; L-T: long-term evidence; LE: limited evidence. Results: Soft tissue augmentation procedures may be indicated for the increase of soft tissue thickness and keratinized tissue, the reduction of interproximal peri-implant bone loss, and the coverage of shallow peri-implant soft tissue recessions (S-T, LE), L-T is lacking. Guided bone regeneration approaches (GBR) showed efficacy when used for ridge reconstruction after the complete healing of the soft tissues (S-T & L-T), and the stability of the augmented bone may play a role in the maintenance of the soft tissue position and dimensions (LE). No significant differences were observed between titanium and zirconia abutments when evaluating probing pocket depth, bleeding on probing, marginal bone levels and mucosal recessions. Zirconia abutments were associated with more biological complications but demonstrated superiority in terms of achieving natural soft tissue colour (S-T).

Journal article (peer-reviewed)abstract
- Osteoporosis has been called a potential risk factor for bone healing around implants.The aim of this multicentre study was to verify the clinical performance of fluoridated implants in the maxilla of subjects with diagnosed systemic primary osteoporosis/osteopenia.Postmenopausal women in need of 2-8 splinted implants in maxilla underwent bone mineral density measurements in the hip and spine, using dual-energy X-ray absorptiometry scans. Based on their T-scores, they were divided into two study groups: Group O (osteoporosis/osteopenia group) subjects had a T-score ≤-2, Group C (control group) had a T-score of ≥-1, and subjects with a T-score <-1 but >-2 were excluded. Implants were placed with a two-stage procedure and loaded 4-8weeks after abutment surgery. At 6months and 1year after functional loading, clinical parameters (including peri-apical radiographs) were assessed.One hundred and forty-eight implants were placed in 48 subjects (mean age: 67years (range [59-83]). Sixty-three implants were placed in 20 osteoporosis subjects (Group O, mean age: 69years; range [59-83]), and 85 were placed in control subjects (Group C, mean age: 65years; range [60-74]). The cumulative survival rate, on an implant level, was 99.3% (Group O: 98.4%; Group C: 100.0%). The cumulative survival rate, on a subject level, was 97.9% (Group O: 94.7%; Group C: 100.0%). Marginal bone level (MBL) alterations from functional loading to the 1-year follow-up visit were measured on an implant level and a subject level. The overall MBL alteration on an implant level was -0.01±0.51mm (Group O: -0.11±0.49mm; Group C: 0.05±0.52mm). The overall MBL alteration on a subject level was -0.04±0.27mm (Group O: -0.17±0.30mm; Group C: 0.04±0.23mm).Within the limitations of this prospective, non-randomized, controlled, multicentre study, it can be concluded that oral implant therapy in patients suffering from osteoporosis/osteopenia is a reliable treatment option with comparable integration rates as in healthy patients. Long-term follow of the study groups is necessary to compare marginal bone alterations and treatment outcomes.

Bone augmentation by means of a stiff occlusive titanium barrier : a study in rabbits and humans
- 2003
-
In: Clinical Oral Implants Research. - : Wiley. - 0905-7161 .- 1600-0501. ; 14:1, s. 63-71
-
Journal article (peer-reviewed)abstract
- It has already been shown that occlusive titanium barriers have osteoconductive properties. These barriers, however, cover only a limited surface area and have only been used in animal experiments. The aim of this study was to evaluate bone neogenesis under a pre-shaped titanium barrier placed over the top of the rabbit skull and the top of highly resorbed edentulous upper-jaw bone in patients. Computed tomography (CT) scans made it possible to pre-shape the titanium barrier according to individual bone shape in human experiments. On the rabbit skull, tissue augmentation of up to 6 mm 1 year after barrier placement was observed, while the original thickness of skull bone was on average between 1.5 and 2.5 mm. The bone, which remained histologically immature for 1 year, grew systematically along the titanium surface, illustrating its osteoconductivity. Even after removal of the barrier, on average, 75.3 and 59.4% of the newly created tissue volume was maintained after 3 and 9 months, respectively. Clinical observations on 10 consecutive patients showed that, in those (5/10) in which the barrier remained unexposed for several months, an increase of the jawbone height and width of up to 16 mm could be observed when the barrier was removed after 12-18 months. As in the rabbits at barrier removal, the bone demonstrated a limited degree of mineralization as ascertained from biopsies. This newly formed osteoid tissue allowed the insertion of 33 screw-shaped titanium implants which in most cases (30/33) successfully osseointegrated to support a fixed prosthesis. The surrounding marginal bone level remained stable even up to 5 years after implant placement. Both animal and clinical data demonstrate that guided bone neogenesis under a subperiosteally placed titanium barrier can reach large volumes.
