1. Influence of Abutment Collar Height and Implant Length on Stress Distribution in Single Crowns
Resumo Este estudo avaliou a influência da altura da porção transmucosa do pilar protético com junção cone morse e do comprimento dos implantes no comportamento biomecânico coroas unitárias com diferentes proporção coroa-implante. Seis modelos virtuais (S11, M11, L11, S13, M13 e L13) foram construídos combinando pilares protéticos com transmucoso

2. Effect of Different Doses of Synthetic Parathyroid Hormone (1-34) on Bone around Implants: a Preclinical Rat Model
Resumo O objetivo deste estudo foi avaliar o efeito de uma menor dose de PTH (1-34) sobre o potencial osteogênico da cicatrização óssea ao redor de implantes de titânio inseridos na tíbia de ratos. Um estudo paralelo cego foi conduzido em 45 ratos Wistar machos adultos. Cada rato recebeu um implante de titânio (4,5 x 2,2 mm) e foi aleatoriamente desig

3. Denaturation processes of collagen from cow bones as a function of temperature
ABSTRACT The thermal stability of collagen is of great interest for the scientific communities both of medicine and archaeology. In medicine, the interest is focused to the reconstruction and repair of bone and cartilage, given the frequency and importance of pathological situations. In contrast, in archaeology the interest is focused to infer from buried an

4. Horizontal Bone Reconstruction on sites with different amounts of native bone: a retrospective study
Abstract: The lack of guidelines for bone augmentation procedures might compromise decision making in implantology. The objective of this study was to perform a retrospective study to verify the outcomes of horizontal bone reconstruction in implant dentistry with different types of materials and amounts of native bone in the recipient bed to allow for a new

5. Finite Element Study of Three Different Treatment Designs of a Mandibular Three Implant-Retained Overdenture
Abstract This study compares ball, bar-clip and bar-ball attachment systems for implant-retained mandibular overdentures with three implants. The first implant is placed in the middle of the mandible and the other two are imbedded in the first premolar regions. Linear elastic finite element analysis is used for design analysis. Three dimensional geometry of

6. Correlation between ultrasound velocity and densitometry in fresh and demineralized cortical bone
OBJECTIVE: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals. METHODS: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were first measured. The bone segments were then divided into four groups of 15 segments each and demineralized

7. Physical and mechanical characterization of a porous cement for metaphyseal bone repair
OBJECTIVE: Macroporous cement with mechanical properties similar to cancellous bone may improve the treatment of large bone defects in relation to solid acrylic cement. The aim of this study was to compare physical and mechanical characteristics of a polymethyl methacrylate (PMMA) based porous cement with cancellous bone. METHODS: Compressive strength and p

8. Histomorphometric analysis of the femoral neck in patients with and without femoral neck fracture
OBJECTIVE: To determine, through bone histomorphometry in femoral neck, whether there are differences in the cancellous bone of the proximal femur from female patients over 60 years old who had femoral neck fracture and similar patients who did not have such fracture.METHODS: We analyzed the trabecular part of the femur of 13 female patients, aged over 60 ye

9. Two and three-dimensional morphometric analysis of trabecular bone using X-ray microtomography (µCT)
INTRODUCTION: Trabecular bones have a porous microstructure and can be modeled as linear elastic solids, heterogeneous and anisotropic. In the literature, few investigations have compared the two- dimensional (2D) and three-dimensional (3D) morphometric analyses of cancellous bone. METHODS: In this investigation eighteen cylindrical samples of cancellous bon

10. Filling of extraction sockets of feline maxillary canine teeth with autogenous bone or bioactive glass
PURPOSE: To evaluate bone healing in the extraction socket of the feline maxillary canine tooth after grafting. METHODS: Eighteen adult cats were submitted to unilateral extraction of maxillary canine tooth and divided into three groups. In group 1 (n=6), control, the extraction socket was left empty. In group 2 (n=6), the extraction socket was filled with a

11. CONTRIBUIÇÕES CIRÚRGICAS PARA O TRATAMENTO DA INSTABILIDADE ATLANTOAXIAL EM CÃES / CONTRIBUTIONS TO SURGICAL TREATMENT OF ATLANTOAXIAL INSTABILITY IN DOGS
Esta tese foi realizada em duas etapas distintas, sendo a primeira destinada à criação de um método alternativo de acesso cirúrgico a articulação atlantoaxial. O objetivo foi apresentar uma variação na técnica de acesso ventral à articulação para tratamento da instabilidade atlantoaxial sem a secção do músculo esternotireóideo. Foram utiliza

12. SUBPRODUTOS DA FRESAGEM FEMORAL OU OSSO ESPONJOSO AUTÓGENO NA OSTEOSSÍNTESE FEMORAL COM HASTES BLOQUEADAS EM CÃES / FEMORAL INTRAMEDULLARY REAMING BYPRODUCTS OR AUTOGENOUS CANCELLOUS BONE IN FEMORAL OSTEOSYNTHESIS WITH INTERLOCKING NAILS IN DOGS
O objetivo desta pesquisa foi avaliar a técnica de hastes bloqueadas na osteossíntese de fraturas femorais em cães e avaliar o uso de subprodutos da fresagem intramedular femoral como adjuvante na cicatrização óssea. Foram utilizados 12 cães, pesando entre 15 e 18 kg, distribuídos aleatoriamente em três grupos iguais de acordo com o tipo de enxerto
