Microestrutura e resistência à corrosão do Ti c.p. soldado a laser utilizando em prótese sobre implantes

Foram realizados estudos para avaliar a microestrutura, a dureza e a resistência à corrosão do titânio comercialmente puro-Ti c.p. soldado por laser e utilizado na confecção de prótese sobre implantes. Verificou-se que na soldagem a laser a microestrutura apresentou três regiões distintas: o cordão de solda, a zona afetada pelo calor - ZAC e o metal base. O Ti c.p. possui microestrutura granular, a microestrutura do cordão de solda é mais refinada e de maior dureza do que o metal base. A ZAC obtida por este processo de soldagem foi relativamente pequena quando comparada com o processo de soldagem por brasagem. Os ensaios eletroquímicos mostraram que a região da solda apresentou menor resistência à corrosão em meio de NaCl 0,15 molL-1 à temperatura ambiente.

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.

Prótese total imediata: relato de caso clínico

The immediate complete denture is defined as a removable or partial denture made to be installed immediately after the extraction of the natural teeth. This type of prosthesis can be used for a short period of time, for aesthetic reasons, mastication, occlusal support, convenience or for the adaptation of the patients to the edentulous state, until the final prosthesis is installed. The objective of this study was to report a surgical and prosthetic rehabilitation planning of a patient by means of an immediate complete maxillary denture, and the results obtained with this treatment modality. The immediate complete denture is a necessary, well-established, useful and effective prosthetic procedure for patients who, inevitably, will present an edentulous state, despite it is a slightly more expensive and it requires more sessions for adjust

Reabilitação protética com associação entre prótese parcial removível e implante dentário: relato de caso

Removable partial denture improve functional and aesthetic failures caused by partial loss of teeth, however specific characteristics of each patients can determine the success of treatment, especially with regard to the support of the prosthesis, which may depend on teeth, the combination of teehe and mucosa and currently associated with the dental implants. The aim of this study is report a case in which there was the need of the association, to enable better aesthetics and self-esteem to the patients. After implant placement and fabrication of prosthetic patient reported satisfaction with the rehabilitation treatment, improving their quality of life.

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.

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.

Parafunção severa: reabilitação oral com prótese total mandibular x overlay maxilar: relato de caso

In many oral rehabilitation professionals seeking venture renew people smile. However, these procedures have functional implications and aesthetic criteria which must be satisfied so that the final result is predictable. The restoration of relations intermaxillary, phonetics, masticatory function, esthetics and patient comfort are the goals to be achieved. An effective way to achieve these goals when immediate reconstruction with permanent dentures is not possible, make use of a type of partial denture called overlay. Bruxism is a manifestation of biopsychological imbalance that affects the stomatognathic system, characterized by clenching and / or attrition of teeth together so centric or eccentric, can be manifestation of nocturnal or diurnal. Its effects can manifest themselves in different parts of the stomatognathic system, varying the severity of the damage as the resistance of the structures affected, the time of existence, its regularity and the general state of the wearer. The description of the steps followed in solving this case, in which the patient edentulous mandibular arch while the maxillary arch showed absence of teeth 16 and 26 and, except for the teeth 17 and 27, all other teeth showed wear very sharp in the sense denoting incisal cervical, severe impairment of the vertical dimension, the quality of masticatory function and a marked impairment phonetic, this case report aims to guide the beginning of a rehabilitation, as well as the transitional phase of treatment for recovery of functional and aesthetic relationships intermaxillary .

Emprego de prótese intra-ocular de resina acrílica. Estudo experimental em ratos

Foram eviscerados os globos oculares esquerdos de 32 ratos, linhagem Wistar, divididos em quatro grupos (A, B, C, D) constituídos, cada um, de cinco testemunhas e três controles. Nos animais-testemunha introduziu-se, dentro da capa córneo-escleral, uma esfera de resina acrílica (metilmetacrilato), previamente confeccionada e esterilizada por autoclavagem, ao passo que nos controles a cavidade eviscerada foi mantida sem prótese. Os ratos dos grupos A, B, C e D foram sacrificados respectivamente aos 7, 15, 30 e 90 dias de pós-operatório, quando os conteúdos orbitários esquerdos foram exenterados e preparados para o exame histopatológico. Observou-se que os animais-testemunha tiveram resposta inflamatória do tipo tecido de granulação ao redor da prótese de cavidade, com edema inflamatório da córnea especialmente nos grupos A e B, quando se iniciou a regressão da inflamação aguda. A cavidade orbitária manteve o tamanho em todos os grupos nos animais-testemunha e houve contração significativa nos animais-controle. Com estas observações, foi possível concluir que a esfera de resina acrílica é uma opção, de baixo custo e fácil confecção, para correção de defeito estético causado pela perda do globo ocular.
