From an ecological viewpoint, the oral cavity, in fact oro-pharynx, is 'open growth system'. It undergoes uninterrupted introduction and removal of both microorganisms nutrients. In order to survive within oro-pharyngeal area, bacteria need adhere either soft or hard tissues resist shear forces. The fast turn-over lining epithelia (shedding 3 x/day) efficient defence mechanism as it prevents accumulation large masses microorganisms. Teeth, dentures, endosseous implants, however, providing...
A classification for peri-implant diseases and conditions was presented. Focused questions on the characteristics of health, mucositis, peri-implantitis, soft- hard-tissue deficiencies were addressed. Peri-implant health is characterized by absence erythema, bleeding probing, swelling, suppuration. It not possible to define a range probing depths compatible with health; can exist around implants reduced bone support. The main clinical characteristic mucositis gentle probing. Erythema, and/or...

Bacterial adhesion to intra‐oral, hard surfaces is firmly influenced by the surface roughness of these structures. Previous studies showed a remarkable higher subgingival bacterial load on rough when compared smooth sites. More recently, additional effect further smoothening intra‐oral clinical and microbiological parameters was examined in short‐term experiment. The results indicated that reduction below R =0.2 μm, so‐called “threshold ”, had no quantitative/qualitative or colonisation,...
Abstract Previous in vivo studies suggested that a high substratum surface free energy (s.f.e.) and an increased roughness facilitate the supragingival plaque accumulation. It is aim of this clinical trial to explore “relative” effect combination these characteristics on growth. 2 strips, one made fluorethylenepropylene (FEP) other cellulose acetate (CA) (polymers with energies 20 58 erg/cm , respectively) were stuck labial central incisors 16 volunteers. Half each strip was smooth (Ra ± 0.1...
It has been documented that the long‐term clinical outcome of Brånemark® system is very favourable. However, failures do occur before and after loading. This study examined differences in marginal bone loss between standard self‐tapping fixtures attempted to explain excessive or osseointegration during first 3 years Marginal (scored on long cone radiographs) fixture failure rate were compared for different designs. For fixtures, comparison with was clearly higher as well successful no...
In nine patients with fixed prostheses supported by endosseous titanium implants, 2 abutments (trans-mucosal part of the implant) were replaced either an unused standard abutment or a roughened abutment. After 3 months habitual oral hygiene, plaque samples taken for differential phase-contrast microscopy, DNA probe analysis, and culturing. Supragingivally, rough harbored significantly fewer coccoid micro-organisms (64 us. 81%), which is indicative more mature plaque. Subgingivally,...
The aim of this retrospective study was to assess the influence systemic and local bone intra-oral factors on occurrence early implant failures, i.e. up abutment connection.The surgical records 2004 consecutive patients from total patient population who had been treated in period 1982-2003 (with a 6946 Brånemark system implants) at Department Periodontology Catholic University Leuven were evaluated. For each medical history carefully checked. Data collection analysis mainly focused...
In a standard periodontal treatment strategy with consecutive root planings ( per quadrant at one- to two-week interval), re-infection of disinfected area might occur before completion the treatment. This study examines, both clinically and microbiologically, whether full-mouth disinfection within 24 hours significantly improves outcome Ten patients advanced chronic periodontitis were randomly allocated test control group. The from group received scalings as well oral hygiene instructions...
The scope of this working group was to review (1) ecological interactions at the dental biofilm in health and disease, (2) role microbial communities pathogenesis periodontitis caries, (3) innate host response caries periodontal diseases.A health-associated includes genera such as Neisseria, Streptococcus, Actinomyces, Veillonella Granulicatella. Microorganisms associated with both diseases are metabolically highly specialized organized multispecies biofilms. Progression these involves...
L-PRF (leukocyte- and platelet-rich fibrin) is one of the four families platelet concentrates for surgical use widely used in oral maxillofacial regenerative therapies. The first objective this article was to evaluate mechanical vibrations appearing during centrifugation models commercially available table-top centrifuges produce impact centrifuge characteristics on cell fibrin architecture a clot membrane. second how changing some parameters protocol may influence its biological signature,...
Abstract Aim: To evaluate the precision of transfer a computer‐based three‐dimensional (3D) planning, using re‐formatted cone‐beam images, for oral implant placement in partially edentulous jaws. Material and Methods: Four formalin‐fixed cadaver jaws were imaged 3D Accuitomo FPD ® computed tomography (CT). Data used to produce an accurate planning with surgery by means stereolithographic drill guides. Pre‐operative CT images subsequently matched post‐operative ones calculate deviation...
Abstract Diagnostics imaging is an essential component of patient selection and treatment planning in oral rehabilitation by means osseointegrated implants. In 2002, the EAO produced published guidelines on use diagnostic implant dentistry. Since that time, there have been significant developments both application cone beam computed tomography as well range surgical prosthetic applications can potentially benefit from its use. However, medical exposure to ionizing radiation must always be...
The aim of this randomized placebo-controlled clinical trial was to evaluate the effects Lactobacillus reuteri-containing probiotic lozenges as an adjunct scaling and root planing (SRP).
Abstract Aim To investigate the influence of use L‐ PRF as a socket filling material and its ridge preservation properties. Materials Methods Twenty‐two patients in need single bilateral closely symmetrical tooth extractions maxilla or mandible were included split‐mouth RCT . Treatments randomly assigned (L‐ versus natural healing). CBCT scans obtained after extraction three months. Scans evaluated by superimposition using original DICOM data. Mean width differences between timepoints...
