“…Several reviews noted insufficient evidence for the need for keratinized mucosa around implants to maintain peri-implant tissue health (16,35,42,43). In the present study, the width of keratinized mucosa was not associated with development of peri-implant diseases.…”

We investigated the prevalences and risk factors for peri-implant diseases in Japanese adult dental patients attending a follow-up visit at dental hospitals or clinics as part of their maintenance program. This cross-sectional multicenter study enrolled patients with dental implants who attended regular check-ups as part of a periodontal maintenance program during the period from October 2012 through September 2013. Patients with implants with at least 3 years of loading time were included in the study. The condition of peri-implant tissue was examined and classified into the following categories: healthy, peri-implant mucositis, and peri-implantitis. Patients were also evaluated for implant risk factors. A total of 267 patients (110 men, 157 women; mean age: 62.5 ± 10.7 years) were analyzed. The prevalence of patient-based peri-implant mucositis was 33.3% (n = 89), and the prevalence of peri-implantitis was 9.7% (n = 26). Poor oral hygiene and a history of periodontitis were strong risk factors for peri-implant disease. The present prevalences were lower than those previously reported. The quality of periodontal therapy before and after implant installation and patient compliance and motivation, as indicated by plaque control level, appear to be important in maintaining peri-implant tissue health.

“…1 Since implant abutments are a part of the superstructure that is in direct contact with peri-implant tissues, their biocompatibility, material structure, surface quality, and shape influence the soft-tissue reaction directly. 2,3 Recent developments in the area of computer-aided design and manufacture (CAD/CAM) enable fabrication of custom implant abutments made of titanium and zirconia ceramic.…”

Objective: CAD/CAM generated ceramic implant abutments have recently attracted interest due to their superior customization possibilities and aesthetic advantages. Despite their widespread clinical use, little information is currently available on their surface topography, however. The transmucosal portion of the abutment shoulder is of particular interest, as it ideally supports soft tissue but minimizes mechanical plaque retention. The aim of this in vitro study was to topographically characterize the trans-and subgingival roughness of CAD/CAM zirconia abutments from different manufacturers and compare them with zirconia stock abutments. Material and Method:The surface topography of eight CAD/CAM zirconia implant abutments (tests) and two prefabricated zirconia stock abutments (controls) was determined using focus variation microscopy. Two points on the abutment shoulder were subjected to profilometric examination. 2D and 3D parameters of roughness were obtained and compared. Results:The surface roughness of all the test abutments exceeded the recommended threshold of Ra = 0.2 µm and therefore exhibited an increased risk of mechanical plaque retention. Obvious differences in surface structure were apparent, allowing conclusions to be drawn about the manufacturing method and subsequent reworking processes. Conclusion:Manually reworking the trans-and submucosal area of the investigated CAD/CAM zirconia abutments appears necessary to fulfil the conditions for optimal surface topography.The Sa value as arithmetic mean, taking the maximum height (Sz value) and surface excess (Sdr) into account, is an essential parameter for assessing the surface topography of implant abutments.

“…Another advantage that seems not to draw much attention in the literature is the abundance of keratinized mucosa that can be achieved in the area of the fistula with a palatal flap, which can be a valuable asset to provide support for a future dental implant in the region [26][27] . As far as the reported limitations of the palatal flap are concerned, limited elasticity did not jeopardize its satisfactory displacement, as, with the technique used, the flap was detached from the periosteum and extended all the way towards the posterior third and soft portion of the palate, where limited elasticity is no longer critical 16 .…”

Sinus lifting has become a routine procedure in modern implant dentistry. Despite RESUMOA cirurgia de elevação da mucosa do seio maxilar para enxerto ósseo e posterior colocação de implantes osseointegráveis vem se tornando um procedimento de rotina na implantodontia moderna. Embora previsível, em alguns casos, tal procedimento, pode levar a complicações e sequelas consideráveis. Na maioria das vezes, essas complicações são ocasionadas por falhas técnicas, como a perfuração da membrana sinusal no momento transcirúrgico, o que pode acarretar perda do enxerto devido a um processo infeccioso no interior do seio maxilar, cuja via de drenagem acaba provocando a comunicação com a cavidade oral. A fístula bucossinusal é caracterizada pela persistência e epitelização desse pertuito. Neste relato é apresentado um caso de fechamento de fístula bucossinusal com o uso de um retalho palatino pediculado, em um paciente que havia desenvolvido um processo infeccioso, após ter sido submetido à realização de uma cirurgia para a elevação do seio maxilar. A cirurgia para o fechamento das comunicações bucossinusais apresenta técnicas variadas, que podem ser eleitas de acordo com as preferências do operador, além da localização e características da comunicação. Para o presente relato de caso, a técnica do retalho palatino pediculado foi eleita para o tratamento cirúrgico, proporcionando a cura do paciente. A técnica do retalho palatino pediculado mostrou-se uma opção adequada para o fechamento da fístula bucossinusal em um único ato cirúrgico, sem perda de mucosa ceratinizada ou diminuição do sulco vestibular na região da fístula.Termos de indexação: Implantes dentários.
