Perda óssea em prótese sobre implante: revisão de literatura

One of the complications that concern prosthetists is bone loss peri-implant, because the success of dental implant treatment requires long-term maintenance of hard and soft tissues around the implant. Whereby the dental implants have not only the goal of restoring function, but also the aesthetics of the patient, the bone loss peri-implant can dramatically compromise the aesthetics of rehabilitation, particularly in anterior regions. The aim of this study was to analyze and reason, through literature review, the main factors that can cause bone loss in peri-implant and possible ways to prevent it.

Higienização em prótese sobre implante

With the advances of osseointegration principles, the use of implant-supported prosthesis has become a routine treatment option. The success of an implant is initially associated to the surgical technique, primary stability and absence of bacterial contamination on the implant site. Subsequently, the absence of mechanical trauma (overload) and peri-implantitis are sine qua non conditions to the longitudinal success of implant treatment. Therefore, the strict maintenance of oral hygiene is highly important to avoid biofilm accumulation around the implant and consequently to provide last-long implant-supported dentures. The clinician has the responsibility to supply a favorable prognosis to the patient so that the rehabilitation succeed. For this reason, during prosthesis fabrication the clinician should observe the design and emergency profile of the prosthesis, the peri-implant sulcus depth as well as the presence of motor or psychological impairment by the patient. Subjects with missing teeth and that will be submitted to the implant treatment should be motivated and adequate instructed regarding oral hygiene and its importance since the best option to obtain treatment longevity and consequently patient’s satisfaction is the prevention. Therefore, this study aimed to perform a literature review about the hygiene of implant-supported prosthesis.

Como realizar o selamento periférico e a moldagem funcional?

The functional impression technique is one of the most important steps for complete and/or partial edentulism treatment. So, correct analysis and record of supporting structures are essential to determine the denture extension. The functional impression technique has two stages - a customized final impression tray and a border impression - which aims to record the optimal denture supporting area. The aim of this study was to review the literature related to border impression and functional impression techniques, describing the technique and materials, and identifying the procedure’s objectives and function.

Abordagem clínica dos registros utilizados para restabelecimento da dimensão vertical de oclusão em prótese total

The determination of occlusal vertical dimension (OVD) is one of the most important steps in the rehabilitation treatment. Although various techniques have been used to measure it, none has proven to be scientifically accurate. Thus, the purpose of this study was to survey the different methods of measuring the vertical dimension and describe the clinical sequence of a method that we deem reliable.

Moldagens em prótese total

The anatomical and functional impressions philosophies are presented to the professionals who are active in the area, so that they can review concepts and thus obtain more precise molds, based on scientific knowledge. In parallel, impression techniques recommended by the Prosthodontics subject from Araçatuba Dental School – UNESP are also commented.

Técnicas de reembasamento para prótese total

Alveolar bone resorption is continuous throughout the life of edentulous patients, the prosthesis mismatch can generate during speech and chewing. An alternative to this would be to destabilize the denture reline, a maneuver which aims to readjust the denture base to the rim by the addition of a plastic film to the inner surface of the prosthesis material. This procedure may be direct, when performed in the clinic, or indirect when made in prosthetic laboratory. The aim this study is to demonstrate the technical of two reline for denture.

Técnicas de confecção de prótese total imediata mucossuportada

The immediate complete denture is a prostheses made prior to teeth extraction, that aims to re-establish the patient aesthetics and function immediately after the removal of the remaining teeth. The objective of this paper is to report the technical procedures during the manufacture of immediate prosthesis. The study reports the clinical steps prior to teeth extraction as well as the surgical and maintenance procedures. The immediate complete denture is a viable rehabilitation method, especially to restore patients’ self-esteem, aesthetics and function promptly. An accurate planning and manufactory beholds better results

Nível de satisfação dos pacientes edêntulos reabilitados com prótese total na faculdade de odontologia de Adamantina FAI

The population’s life expectancy is growing every year. This fact highlights the importance of the elderly for the dentistry. The oral cavity quality has great influence on quality of life at both the biological and the psychological and social factors by maintaining a self-esteem, self-expression, communication and satisfactory facial aesthetics. Unfortunately, the number of edentulous elderly population is also high, which may create problems to their social life. Therefore, the objective of this study was to demonstrate and evaluate the difficulties of treating edentulous patients, comparing data prior to treatment to post data after treatment by complete dentures made to the patients undergoing oral rehabilitation in the Dental Clinic of the Faculty of Dentistry of Adamantina – FAI. For this study, questionnaires were filled in the form of answers developed alternative focused on the degree of patient satisfaction, the current situation of occlusion, and outcome of treatment. The results showed that 96% of patients were satisfied with the results obtained in the treatment, all of whom believed that the prosthesis helped them feel better aesthetically and improved self-esteem. By this methodology, it was concluded that the degree of satisfaction was high, but the services provided must be constantly reevaluated, once the elderly population presents a wide labor market for dental professionals and demand level services will certainly increase each year.

Resolução estética associando prótese sobre implante e prótese convencional na região anterior

The combination of several methods for solving aesthetics in a clinical case can be a complicating factor. The diagnosis and planning of the event held in conjunction with the dental technician expand the possibilities of success. The present case illustrates the aesthetic resolution through the association of implant- and tooth-supported prostheses using metal free ceramic systems. A 38-year old male patient presented with a complex smile. After diagnosis and treatment planning, two ceramic crowns were made, one on tooth 11 and one on the implant region 21, along with a laminated porcelain veneer on the region of 12. Aesthetic needs of the patient are predictable only with a sound diagnosis.

Solução estética para prótese sobre implante

Próteses sobre implantes esteticamente favoráveis estão diretamente relacionadas com a condição dos tecidos moles e duros que as envolvem. A preservação dos tecidos mucogengivais ao redor de implantes dentários instalados na maxila anterior propicia um sorriso harmonioso, com uma estética bastante agradável. No entanto, em alguns casos, isso não ocorre principalmente pela grande reabsorção tecidual na região, na qual deveria ter sido realizado enxerto ósseo, antes mesmo da instalação dos implantes. Desse modo, o objetivo deste trabalho foi apresentar uma solução reabilitadora estética para essas possíveis falhas durante o planejamento com reabilitações sobre implantes, por meio de gengiva artificial cerâmica.

Reabilitação estética por meio de prótese ocular a base de PMMA: relato de caso

Eye loss results on facial asymmetry compromising its aesthetics. Ocular prostheses are important to re-establish aesthetics; protect the anophthalmic cavity; recover function such as the redirection of lachrymatory liquid; and reintegrate the patient to society. The aim of this study was to describe a case report, demonstrating clinical and laboratorial procedures for confection of ocular prostheses and highlighting their advantages. A female patient was afflicted by toxoplasmosis, which led to the loss of her eye. An eye visceration was performed. The patient reported no previous use of ocular prosthesis. A PMMA ocular prosthesis was manufactured restoring patient’s aesthetic and facial contour. The patient was satisfied with the treatment. Therefore the present study has shown that PMMA ocular prosthesis is able to restore facial aesthetics and can be a safe and satisfactory alternative for patients that have lost their eyes due to toxoplasmosis.

Reabilitação de maxila atrófica com tecido ósseo homógeno e prótese fixa implantossuportada

The techniques of bone reconstruction for atrophic maxillae have been improved in order to promote bone tissue growth in both height and thickness. The grafts performed with use of autogenous bone is considered the gold standard by most researchers, for demonstrating osteogenic capacity and not to promote antigenic response. However, this type of grafting is not possible to get bone tissue in large quantity for extensive renovations. In recent years, alternatives have been researched to overcome the limitations of autogenous bone. Several alternatives have been investigated to supply the disadvantages of autogenous bone grafts. In such studies, allogeneic bone grafts which are obtained from individuals with different genetic load, but from the same species have been extensively used. They can be indicated in cases of arthrosplasty, surgical knee reconstruction, and large bone defects as well as in oral and maxillofacial reconstruction. Besides showing great applicability and biocompatibility, this type of bone is available in unlimited quantities. To rehabilitate atrophic maxillae an option that has been performed with high success rate is the reconstruction with bone graft followed by osseointegrated dental implants to rehabilitate the patient aesthetics and functionally. This paper aims to show the feasibility of allogenic bone as material for reconstruction of atrophic maxilla, and subsequent rehabilitation with metal ceramic fixed prosthesis implant and dental restoration with accompanying three years through literature review and clinical case report.
