..No correlation was found between bleeding on probing and marginal bone loss. We conclude that the connection state of 2 implants retaining a hinging overdenture did not influence the peri-implant outcome...

..The idea of not splinting the implants in a fixed partial prosthesis is promising but needs replication before accepting it...

..This study aimed to compare the prosthetic aspects and patient satisfaction with prosthetic care in two-implant-retained mandibular overdentures, whether implants were splinted with a bar or left with magnets or ball attachments...

..The replacement of a single tooth or several teeth by means of single-implant restorations is an increasingly used method that needs long-term validation...

..Eighty-seven per cent of the patients rated their restorations more than 7/10 on an ordered analogue scale for aesthetics as well as for function...

..16 mm only. Thus non-sleeping implants lose on average more bone when compared to sleeping implants. Surgical trauma at the abutment connection is believed to be the most plausible cause of marginal bone loss around non-sleeping implants...

..Finally, the clinical outcome of all groups confirms that overdenture treatment demands regular controls with limited time intervals...

..All patients would repeat the same treatment even though the majority of the Magnet group would prefer a more retentive solution because of limited denture stability...

..However, the clinical significance of greater bone loss in rigid versus non-rigid connections might outweigh the annoying phenomenon of tooth intrusion in the case of non-rigid tooth connection, when connection is considered...

..This retrospective analysis evaluated the peri-implant parameters of implants supporting a 'planned' overdenture in the maxilla, and compared these data with those of an age-matched control group, with a fixed full dental prosthesis...

..Some clinical observations support this hypothesis...

..Because of the different nature of the tissue phenotypes used to describe the differentiation processes, it is however hard to compare both models in terms of their validity...

..These results however are a strong indication of the feasibility of the implemented theory to predict the mechano-regulation of the differentiation process inside the bone chamber...

..Procedures to optimise the mechanical properties of bone scaffolds, in relation to those of native trabecular bone are discussed...

..p.) titanium implants retaining hinging mandibular overdentures...

..The original protocol of Brånemark to achieve predictable osseointegration for oral implants has substantially been modified. One may question whether results are influenced by those modifications, especially for the long-term prognosis...

..0001) then after tightening the gold cylinder in all test conditions (five or six, four or three supporting implants). This study underlines the static load present after screw tightening implant supported fixed full prostheses...

..From the present results, it could be concluded that in patients rehabilitated with oral implant-supported prostheses speech disorder is more frequently observed than in subjects with a natural dentition...

..p. titanium implants with a machined surface (Brånemark system implants) was not influenced by the progression rate of periodontal destruction around the remaining teeth within the same jaw...

..On the other hand, the same approach in patients with congenital defects or who underwent radiotherapy is deceptive. The use of hyperbaric oxygen may dramatically improve these results...

..This retrospective analysis evaluated the long-term outcome of two implants supporting an overdenture in the mandible, as well as the significance of some confounding factors (smoking, implant length, bone quality)...

..Hence they should be integrated correctly in numerical models of in vivo behaviour of oral implants. This necessitates the creation of patient-dependent finite element models...

....

..CONCLUSIONS: The selected imaging techniques showed an acceptable accuracy for peri-implant bone level measurements with an overall error of less than 0.5 mm. Intra-oral images showed the smallest absolute differences...

..The periodontal condition of the UDA anchor abutment teeth was not significantly different from that of the contralateral side. The number of failures, especially the number caused by recurrent caries, is cause for concern...

....

..CONCLUSION: Implants provided anchorage control for tooth movement and created the possibility of prosthetic rehabilitation through a multidisciplinary treatment approach...

..Well-controlled micro-motion positively influenced bone formation at the interface of a roughened implant. An improved bone reaction was detected with increasing micro-motion...

..Tissue formation at the implant interface is known to be sensitive to mechanical stimuli. The aim of the study was to compare the bone formation around immediately loaded versus unloaded implants in two different implant macro-designs...

..The present study evaluated the bone response around a turned (T) and a roughened (R) implant for either an unloaded or a well-controlled loaded situation...

..However, a bone-stimulating effect in the implant's vicinity was assigned to the rough surface when the implant was loaded...

..The present study evaluated the influence of well-controlled mechanical stimuli on the tissue response around immediately loaded cylindrical turned titanium implants at two different observation periods...

..The hypothesis that the existing mechanoregulatory models were able to predict the patterns of tissue formation in the in vivo bone chamber could not be fully sustained...

..A detailed insight into the early healing response of trabecular bone to unloaded titanium implants is lacking...

..The goal of this study was to examine the feasibility of in vivo imaging of trabecular bone around titanium implants by means of microfocus computed tomography (micro-CT) and the use of rabbits for this purpose...

..Periodontitis and peri-implantitis are linked to the presence of several key pathogens. The treatment of these infectious processes therefore involves the reduction/eradication of bacteria associated with periodontitis...

..Marginal bone strains at the buccal and/or lingual sides, however, did not increase...

..CONCLUSIONS: Butt-joint and internal-cone oral implants have similar force distribution characteristics. The implant-abutment mating design is not a decisive factor affecting stress and strain magnitudes in a bone simulant...

..Both animal and clinical data demonstrate that guided bone neogenesis under a subperiosteally placed titanium barrier can reach large volumes...

..Repeated sampling of the bone chamber allows conducting several experiments within the same animal at the same site, thereby excluding subject- and site-dependent variability and reducing the amount of experimental animals...

..Especially comparisons between fixed full prostheses (FFPs) and overdentures (ODs), or between anchoring systems for the latter are scarce...
