ABSTRACT

Parameters such as the correct 3-dimensional positioning and the quality of peri-implant soft tissues are fundamental to the success of implant-supported restorations. Digital planning and guided surgery techniques can make the implant placement more accurate, and modifying the periodontal phenotype is often fundamental to increasing esthetics and peri-implant health, mainly in esthetic areas. This article describes a guided surgery technique that assists in the 3-dimensional positioning of implants and identifies the best anatomic area (volume and safety) for obtaining a palatal gingival graft.

ABSTRACT

Making an intraoral digital scan of the emergence profile is a clinical challenge. The peri-implant soft tissue collapses after removal of an interim prosthesis, which compromises the correct design of a definitive implant-supported prosthesis. Although techniques are available for digitally reducing such a distortion, achieving a correct alignment of scans to replicate the internal and external characteristics of the peri-implant tissue is still challenging. This article describes an alternative technique for achieving a precise alignment of the peri-implant soft tissue emergence profile generated with an interim prosthesis.

ABSTRACT

Atrophic maxilla rehabilitation through dental implants is always a challenging procedure. However, alternative approaches such as guided surgery and the installation of short implants are progressively supplanting more invasive bone regeneration procedures. A V-4 technique described in 2016 facilitates the installation of dental implants in patients with atrophic maxilla; however, its authors recommend incision, flap opening, and elevation of the anterior area of the maxillary sinuses. This case report describes a less invasive proposal for modifying the technique through the association of guided surgery, which improves implant placement accuracy, shortens surgical time, and reduces morbidity.

ABSTRACT

Apesar da vasta literatura científica e das novas tecnologias, substituir elementos na região maxilar anterior continua sendo um grande desafio estético quando utilizamos a terapia com implantes osseointegrados. Este artigo relata um caso clínico em que um paciente do sexo masculino, 27 anos, que apresentava agenesia dos dois incisivos laterais superiores, após tratamento ortodôntico, teve os elementos substituídos por implantes osseointegrados. Regeneração tecidual guiada (RTG) utilizando osso bovino desproteinizado em conjunto com uma membrana de colágéno natural foi necessária para compensar defeitos ósseos vestibulares bilaterais. Imediatamente após o ato cirúrgico, duas coroas definitivas de cerâmica foram cimentadas. A proservação aos 18 meses demonstra boa estabilidade dos tecidos (AU).


Despite the vast scientific literature and new technologies, to replace elements in the anterior maxillary region remains a great aesthetic challenge when using osseointegrated implant therapy. This paper reports a clinical case of a male patient, 27 years old, who presented agenesis of two upper lateral incisors, and that had the elements replaced by osseointegrated implants after orthodontic treatment. Guided tissue regeneration (GTR) using deproteinized bovine bone in conjunction with a natural collagen membrane was required to compensate bilateral vestibular bone defects. Immediately after surgical procedure, two ceramic crowns were cemented. After 18-months follow-up, the case showed good tissue stability (AU).

ABSTRACT

Para ser a primeira opção em um plano de tratamento, a terapia com implantes deve atender requisitos funcionais e estéticos. A técnica de instalação de implantes imediatos tem sido indicada devido à diminuição do tempo de tratamento, o que traz benefícios para o paciente. Antes de avaliar a viabilidade do implante, é essencial o conhecimento da indicação para uma adequada instalação em área infectada. Áreas de infecção periodontal subaguda, infecção perio-endo, infecção periodontal crônica, lesão periapical crônica e cisto periodontal só devem receber implantes imediatos desde que medidas pré, pós e durante o procedimento cirúrgico sejam tomadas. O presente artigo relata um caso de instalação de implante imediato em alvéolo infectado com a utilização de enxerto autólogo com 18 meses de acompanhamento (AU).


To be the first choice in a treatment planning, implant therapy must join both functional and aesthetic requirements. Implant installation technique has been indicated due to the reduction of time treatment, which brings benefits to the patient. Before evaluating the viability of the implant, it is essential to know the proper indication of the immediate implant installation in an infected area. Areas of subacute periodontal infection, endo-perio lesion, chronic periodontal infection, chronic periapical lesion, and periodontal cyst should only receive immediate implants provided that measures are taken pre, post, and during surgical procedures. The present article reports 18 months follow up after the installation of an immediate implant in infected socket associated to autologous graft (AU).

ABSTRACT

The placement of dental implants and subsequent placement of immediate temporary dentures after extractions has become a treatment modality accepted by the scientific community. In addition to the functional factor, the surgical procedure in a single stage in the anterior region of the maxilla offers an esthetic appearance, and relieves the psychological concerns of patients. To guarantee the success and longevity of treatments performed, the fabrication of surgical guides is a helpful method in these situations. Guided surgery has gained attention because it restores esthetics with immediate restoration, provides the patient with comfort in addition to dispensing with the need for performing surgical flaps. This auxiliary method allows the position and design of the implant, as well as the perforation sequence to be programmed, thus optimizing the clinical results. In this study, the authors present a clinical case of a patient who was submitted to extraction and subsequent implant placement with immediate loading in the anterior region of the maxilla, performed in a satisfactory manner.

ABSTRACT

OBJECTIVE: This systematic review evaluated survival rates, marginal bone loss (MBL), and complications of using 2 to 4 implants to support full-arch fixed prostheses in the mandible. MATERIALS AND METHODS: An electronic search was performed in PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials to identify relevant articles published until March 2015. Articles were critically reviewed to determine the level of quality. RESULTS: The initial search resulted in 910 articles from PubMed/MEDLINE, 162 titles from the Cochrane Central Register of Controlled Trials, and 363 from the Web of Science. After an initial assessment and careful reading, 19 studies published between 1999 and 2014 were included in this review. CONCLUSIONS: The results of this review suggest that full-arch fixed dental prosthesis in mandible supported by 2 to 4 implants exhibited a low rate of failures for implants and prostheses, a low rate of MBL, and a low rate of biomechanical and biological complications.

ABSTRACT

A infecção dos tecidos peri-implantares é um problema que acomete um número significativo dos pacientes submetidos a reabilitações orais com implantes osseointegrados. O tratamento das infecções dos tecidos peri-implantares visa a manutenção do implante na cavidade oral removendo as áreas infectadas, porém as terapias ressectivas normalmente levam a sequelas estéticas. A utilização de técnicas regenerativas associadas ao tratamento da peri-implantite apresentam um bom prognóstico e minimizam as complicações estéticas. O presente artigo relata um caso de tratamento da peri-implantite por meio da técnica de regeneração óssea guiada com acompanhamento de 24 meses (AU).


The infection of the tissues around the implants is a problem that affects a large number of the patients treated with osseointegrated implants. The treatment of this infections aim to maintain the viability of the implants in the oral cavity by removing the contaminated areas, however the resective therapies usually lead to poor aesthetic results. The use of regenerative techniques associated to the treatment of peri-implantitis have a good prognosis and minimize the aesthetic complications. This article reports a case of treatment of peri-implantitis through guided bone regeneration technique led to a 24-month follow-up (AU).

ABSTRACT

Apesar do avanço no conhecimento científico biológico e com melhores instrumentos para o planejamento, a perda de dois elementos dentários contíguos na região maxilar anterior continua sendo um grande desafio estético quando utilizamos a terapia com implantes osseointegrados. Este artigo relata um caso clínico em que um paciente do sexo masculino, 27 anos, teve dois incisivos centrais substituídos por implantes osseointegrados após o trauma. A opção foi a instalação de um implante no local incisivo central esquerdo com uma coroa provisória imediata cimentada, e atrasar a implantação no sítio do incisivo direito por seis meses. Regeneração Tecidual Guiada (RTG) foi necessária para o site incisivo central direito. Osso bovino desproteinizado com colágeno a 10% (Bio-Oss Collagen®) foi usado em conjunto com uma membrana de colágéno natural (Geistlich Bio Gide®). Depois de seis meses, um implante foi instalado no sítio do incisivo direito e, após período igual de tempo, duas coroas de cerâmica com base CAD-CAM de zircônia foram cimentadas. A proservação de seis meses demonstra boa estabilidade dos tecidos (AU).


Better planning tools are available, but, even following biological scientific parameters, the substitution of two adjacent teeth in the maxillary anterior region remains a major challenge when using cosmetic dental implants therapy. This article reports a clinical case where a male patient, 27 years old, had two central incisors replaced by osseointegrated implants after trauma. The option was to perform the immediate installation of an implant at the left central incisor site with a cemented immediate provisional crown, and delay for six months the placement of the implant at the right incisor site. Guided tissue regeneration (GTR) was necessary for the right central incisor site. Deproteinized bovine grafting material with 10% collagen (Bio-Oss Collagen®) was used with a natural collagen membrane (BioGide®). Six months later an implant was installed at the right incisor site and, after the same period of time, after casting and scanning, two CAD-CAM zirconia based ceramic crowns were cemented. After six months the tissues showed good stability (AU).

ABSTRACT

Apesar do avanço no conhecimento científico biológico e com melhores instrumentos para o planejamento, a perda de dois elementos dentários contíguos na região maxilar anterior continua sendo um grande desafio estético quando utilizamos a terapia com implantes osseointegrados. Este artigo apresenta um caso clínico no qual uma paciente de 25 anos teve dois incisivos centrais perdidos, por reabsorção interna e externa após trauma e tratamento endodôntico, substituídos por implantes dentários. Enquanto no sítio do elemento 21 foi possível instalar um implante imediatamente após a extração, com provisório imediato, no sítio do elemento 11 foi necessária a execução de regeneração tecidual guiada. Um bloco de material xenógeno bovino desproteinizado (Bio-Oss Block) foi utilizado em conjunto com uma membrana de colágeno natural suíno (Bio-Gide) para este fim. Após seis meses, um implante foi instalado no sítio 21. Após a moldagem e escaneamento, dois pilares de zircônia e duas coroas de cerâmica com base de zircônia foram fabricados, instalados e cimentados de maneira precoce, 12 dias após a segunda implantação. O controle após seis meses demonstra boa estabilidade dos tecidos.


Although advances on treatment planning tools and biological knowledge have been made, the loss of two adjacent teeth in the anterior maxilla continues to be a great esthetic challenge when dental implants are to be inserted. This case report presents a 25 years-old patient where the two central incisors had to be removed due to internal and external root resorption after trauma and endodontic therapy. While in the region of tooth 21 it was possible to insert a dental implant soon after tooth removal, a guided tissue regeneration procedure was necessary at the region of 11. Thus, a deproteinized bovine xenogeneic bone block (Bio-Oss Block) was grafted along with a natural collagen porcine membrane (BioGide). After six months, a dental implant was placed in the same region. After impression and scanning, two zirconia abutments and zirconia-based defi nitive ceramic crowns were fabricated and cemented 12 days after the second implant surgery. The six-moth postoperative results demonstrate good tissue stability.

ABSTRACT

PURPOSE: To evaluate the angulation of the maxillary sinus walls at the apical sinus region. MATERIALS AND METHODS: Using preoperative computerized tomographies of 15 patients selected for sinus lift procedures, the angulation of the maxillary sinus floor was measured drawing straight lines tangential to the mesial and lateral walls. The measurements were taken from sagittal images at specific areas (i.e., second bicuspid, first molar, and second molar). RESULTS: The results showed that the second bicuspid sites have a sharper angulation than the second molar sites, and these second molar sites have a sharper angle than the first molar sites. CONCLUSION: The sharper angle observed in the second bicuspid area can influence the feasibility of schneiderian membrane evaluation when compared to the molar areas.

ABSTRACT

A instalação de implantes associada com a cirurgia de levantamento do assoalho sinusal pode ser realizada no mesmo estágio ou num estágio cirúrgico posterior, dependendo da quantidade de osso residual localizado sob o antro maxilar. Para que esta instalação dos implantes seja realizada simultaneamente ao levantamento do assoalho sinusal é fundamental que este rebordo residual possa proporcionar estabilidade inicial adequada aos implantes. Uma altura óssea mínima de 5 mm foi inicialmente estabelecida como quantidade mínima para permitir esta estabilidade. Estudos demonstram resultados confiáveis com a instalação simultânea de implantes cilíndricos revestidos de hidroxiapatita em seios maxilares com rebordos extremamente atrésicos (de 1 a 2 mm), como uma forma de otimizar o procedimento de minimizar a morbidade. A viabilidade de utilização de implantes rosqueados possibilita um melhor controle de angulagem de instalação quando comparados aos implantes cilíndricos. O objetivo deste trabalho é apresentar um recurso técnico que viabiliza com segurança a instalação de implantes rosqueados simultaneamente a elevação de seios maxilares extremamente pneumatizados
