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.

Deslocamento de implante dentário para o seio maxilar: relato de caso

The residual alveolar ridges may be unfavorable for implant placement. The edentulous maxilla is often challenging for the oral surgeon because of the lack of bone as a consequence of alveolar ridge resorption and/or maxillary sinus pneumatization. Accidents or complications may occur when some of these issues are not being known. This article reports one case of implant displaced into the maxillary sinus, 27 days after sinus bone augmentation with simultaneous dental implant installation, causing moderated sinusitis symptoms. The implant was removed through oral cavity access to maxillary sinus.

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.

Influência da angulação do implante e tipo de intermediário na distribuição das tensões

The aim of this study was to evaluate the influence of implant angulation and abutment type (UCLA and Estheticone) on stress distribution in screw-retained implant-supported prostheses through photoelasticity. Three models were fabricated with photoelastic resin PL-2 (Vishay, Micro-Measurements Group, Inc Raleigh, N.C., USA) containing one external hexagon implant with 3.75x10mm (Master screw, Conexão Sistemas de Prótese Ltda., Arujá, São Paulo) with 0°, 17° and 30° degrees and a screw-retained prostheses with UCLA and Estheticone abutments. The assembly was positioned in a circular polariscope; axial and oblique (45° degrees) loads of 100N were applied in fixed points on the occlusal crown surfaces by a universal testing machine. The stress generated was photographed and analyzed qualitatively with appropriate software (Adobe Photoshop®). The results demonstrated the same number of fringes for both abutment types for each angulation, with fringes increasing in the same way. A higher number of fringes were closer in the oblique loading mode. It was concluded that there was no significant difference in stress distribution in prostheses with UCLA and Estheticone abutments. Higher stress concentrations were observed with increased implant angulation. Stress concentration and intensity were higher in the oblique load than in axial load application.
