Purpose. To present the outcomes of immediately loaded single implants placed in the anterior maxilla. Methods. Over a 2-year period, all patients referred to a private clinic were considered for enrolment in this study. Inclusion criteria were single-tooth placement in postextraction sockets or healed sites of the anterior maxilla. All implants were immediately loaded and followed for a period of 1 year after the placement of definitive crowns. The outcome measures were implant stability, survival, and success. Results. 34 patients were selected and 43 tapered implants with a knife-edge thread design and a nanostructured, calcium-incorporated surface (Anyridge®, Megagen, Gyeongsang, Korea) were installed. Two implants were not sufficiently stable at placement (ISQ < 60) and were considered failed for immediate loading; 41 implants had an ISQ ≥ 60 at placement and were immediately loaded. One year after the placement of definitive crowns, no implant failures were reported, for a survival rate of 100%. No biological complications were found, but 2 implants had their prosthetic abutments loosened: the implant success rate was 95.2%. Conclusions. In the present study on the immediate loading of single implants in the anterior maxilla, positive outcomes were reported, with high survival (100%) and success (95.2%) rates (the present study has been registered in the ISRCTN registry, a publicly available trial register recognized by WHO and ICMJE, with number ISRCTN12935478).

Abstract This clinical report describes the traumatic avulsion of the left maxillary central and lateral incisors with minimal tissue trauma, followed by placement of provisional restorations of two root-form implants in a 14-year old female patient. Ten days following the avulsion, implant therapy was performed with Summers osteotomes and flapless technique using a root-form 3i osseotite NT. Angulated abutments and acrylic provisional crowns were placed. No occlusal contact was detected. An impression was made 30 days after implant insertion and ceramic restorations were placed 3 months later. No significant soft tissue contraction was observed during the provisional period. The patient exhibited no clinical or radiologic complications for 8 months after loading. In carefully selected under-aged patients implant therapy and immediate loading in the anterior maxilla for traumatic tooth avulsion may prove to be valuable to avoid soft tissue contraction, alveolar bone resorption, and positive esthetic/psychological response.

Background: COVID-19 neurological manifestations were demonstrated during the pandemic, including cognitive impairment. Objectives: To determine the prevalence of cognitive and behavioral complaints (such as dementia, MCI or SCD) in a outpatient sample with recent SARS-COV2 infection. Specific: Evaluate the association of cognitive impairment with the presence of the polymorphism found in the APOE gene and with respiratory disease. Methodology: Observational, longitudinal, prospective clinical study. Inclusion criteria: patients with confirmed Covid-19. Patients are evaluated in an outpatient clinic. They are evaluated through a standardized attendance record, with somatic and cognitive neurological assessment. Cognitive assessment involves the application of cognitive (ACER, MMSE and CDR), functional (Pfeffer) and psychiatric (GDS or Beck) screening instruments, in addition to subsequent extensive neuropsychological assessment. In addition, APOE polymorphism is analysed. Preliminary. Results: To date, 191 patients and 11 controls were evaluated. The average age is 46.5 years, with 65.4% female, 79.16% with 8 or more years of schooling, in addition to 57.5% of the sample with cognitive complaints. Conclusions: The results so far in our study demonstrate that cognitive complaints are frequent in patients even in the chronic phase of the disease.

Abstract Immediate loading of splinted implant restorations is a growing trend, but limited clinical documentation hampers evidence-based treatment planning for single-tooth applications. This study prospectively evaluated the clinical efficacy of placing implant-supported, single-tooth restorations into immediate, full-occlusal loading. Sixty consecutive patients (intent-to-treat group) with 1 missing tooth between 2 intact teeth were treated with a total of 69 implants. At placement, final impressions were made and implants were provisionalized with nonoccluding prostheses. Definitive prostheses were delivered 2 weeks later. A claim of noninferiority was made with a 95% confidence interval (Mann-Whitney U test) if the success rates between the experimental group and a 97% historical control was &gt;7%. Standardized radiographs taken at placement and bimonthly intervals were analyzed for crestal bone changes at a type I (alpha) error level of .05; significance levels were not adjusted for multiplicity (Fisher exact tests and Student t tests). Sixteen patients (18 implants) were withdrawn for protocol deviations. The resulting treated-per-protocol group consisted of 44 subjects with 51 implants. Cumulative implant success rates were 98.55% (n = 68/69) for the intent-to-treat group and 98.04% (n = 50/51) for the treated-per-protocol group. There were no significant adverse events or statistically significant differences between the experimental and historical control groups. At 12 months mean crestal bone loss was 1.05 mm, and ranged from 0.38 to 1.5 mm (77%) and 1.6 to 2.69 mm (23%). Immediate full-occlusal loading of single-tooth restorations was safely performed in selected subjects when good primary implant stability and an appropriate occlusal load were achieved.

Conflict across the globe has displaced over 16.1 million refugees, with approximately half under the age of 18. Despite the number of young refugees, there is a dearth of research reporting on the needs of refugee children and youth. The purpose of this systematic review is to begin to fill this gap by summarizing what we know about the needs of refugee children and youth (5–18 years old). Eighteen manuscripts met the study inclusion criteria. In these studies, the identified needs of refugee children and youth were primarily in the domains of social support, security, culture, and education. Several strategies were identified as facilitating their integration, such as mentorship programs. The current review can help inform future integration programs designed for refugee children and youth. Supporting the integration of refugee children and youth, and their families, promotes positive outcomes and is beneficial for both refugees and members of host communities.

Replacing a single tooth in the anterior maxilla is one of the greatest challenges in dentistry. Both functional and aesthetic results are to be strictly pursued. Planning and executing such a case through a totally digital methodology eventually guarantee many advantages, above all patient’s operative and postoperative comfort. To ascertain this, a BOP analysis was performed which allowed us to evaluate soft tissues health, and more; crestal bone resorption was measured to evaluate hard tissues stability. This assumption was studied through four cases in which patients were alternatively treated with analogic and digital techniques. Four homogeneous patients were recruited. They all needed to extract one of the upper incisors, due to different clinical reasons, and then to replace it with an implant. Each patient was treated with an immediate postextractive implant which was immediately loaded, and finally, analogical and digital techniques were compared. All patients underwent a preoperative CBCT examination. After surgery, patients were checked by the surgeon after 10 days and one month to evaluate the progress of healing and to exclude any prosthetic problem. At 6 months (T1), one year (T2), and three years (T3), intraoral x-rays were performed using customized centring devices, according to the parallel beam technique. All data have been collected in a table and statistically processed; mean and standard deviation were measured. All patients entered an oral hygiene program with six months recall. Dental hygienist checked the BOP at T1, T2, and T3. At every step, similar levels of BOP were recorded. About interproximal bone loss, all patients showed an initial moderate loss (between T1 and T2), followed by stable values between T2 and T3. Despite the important limitations of a study with few cases, these results show a similar outcome comparing digital and analogical methods.

Introdução: A reabilitação com implantes dentários tornou-se possível de forma imediata a partir do conhecimento e aplicação da osseointegração. Esse procedimento propicia otimização entre o tempo de osseointegração e maturação óssea, além de minimizar a reabsorção alveolar, preservar a arquitetura gengival, e evitar novo procedimento cirúrgico. Objetivo: Evidenciar o sucesso de implante dentário unitário, instalado imediatamente após exodontia e curetagem de lesão periapical extensa, e a instalação da prótese com proservação de 33 meses. Relato do caso: Paciente do sexo feminino, 24 anos de idade, apresentou-se com uma parúlide na gengiva inserida acima do dente 25 e fratura coronal do mesmo. A tomografia computadorizada de feixe cônico (TCFC) revelou uma extensa área hipodensa na região do ápice da raiz do dente 25, medindo 6,7 X 8,2 mm. A referida lesão já havia causado fenestração da parede vestibular, cerca de dois terços no sentido ápice-coroa. Foi instituído como plano de tratamento a instalação de implante dentário imediato com carga imediata. A prótese final foi instalada 13 meses após a instalação do implante. Decorridos 17 meses do procedimento cirúrgico, foi solicitada radiografia periapical de controle, onde foi possível avaliar trabeculado ósseo sadio em torno do implante. Conclusão: Tendo em vista o avanço dos biomateriais utilizados em reabilitação oral e o aprimoramento das técnicas e profissionais que a desempenham, conclui-se que é possível realizar implantes imediatos e reabilitação imediata em área infectada, mesmo em casos limítrofes, com segurança e efetividade, possibilitando a obtenção de resultado final satisfatório.Descritores: Implantes Dentários; Infecção; Regeneração Óssea.ReferênciasBrånemark PI, Adell R, Breine U, Hansson BO, Lindström J, Ohlsson A.

Purpose Pharmacologic doses of corticosteroid (CS) have been shown to ameliorate the progression of Duchenne muscular dystrophy (DMD) preserving strength, pulmonary function and ambulation as well as reducing the incidence of scoliosis. However, there are serious side effects of CS, which may impact dose tolerance. The purpose of this study was to compare the magnitude of positive CS effects on patients in our clinic to those reported in the literature. Methods We retrospectively reviewed medical records and radiographs of 142 DMD patients who were seen between 1st January 1991 and 31st December 2017. Results In total, 101 boys met study inclusion criteria. Of these 32 were steroid naïve, 37 took the recommended dose (standard of care, SOC) of Prednisone or Deflazacort, and 32 took a lower dose (LD). Following initiation of CS, both treatment groups showed an increase in weight velocity and decrease in linear growth velocity. Although there was a trend to later loss of ambulation (LOA) in the SOC group relative to the naïve group by one year, this was not significant, however, a small subgroup of boys on Deflazacort showed a 3.4 year later LOA than the naïve group. The incidence of scoliosis was reduced from 69% in the naïve, to 41% in the LD and 47% in the SOC group. Conclusions Although there was a reduction in the incidence of scoliosis, it was not as robust as seen elsewhere. Many published studies have inadequate data on scoliosis probably due to the lack of inclusion of orthopaedists in the study group. Level of evidence IV

And Control

The risk of developing white spot lesions (WSLs) after orthodontic treatment with lingual brackets is generally considered lower than with labial ones, even if plaque accumulation is frequently higher due to the increased difficulty level in oral hygiene maintenance. In this prospective clinical study, selective enamel etching technique effectiveness in reducing plaque accumulation and WSLs was tested. Thirty patients were bonded with a split-mouth approach: two randomly selected opposite quadrants were used as the test sides, using customized plastic etching guides, and the other two as control sides, applying traditional direct etching methods. The plaque presence around the braces was recorded after 1, 3, 6, and 12 months according to a lingual plaque accumulation index (LPAI), as was the presence of WSLs. PAI measured values were significantly higher in the control sides during the observation period. Test and control sides differed significantly for new WSL onset only after 12 months of treatment. Therefore, the present research demonstrated that this guided enamel etching technique allowed for significant reduction in plaque accumulation around the lingual brackets and reduced onset of white spots after one year of treatment.
