Book excerpt: LES RECHERCHES CONCERNANT LES PHOSPHATES DE CALCIUM ONT PERMIS DE PROPOSER DE NOUVEAUX SYSTEMES D'IMPLANTS DENTAIRES RECOUVERTS D'HYDROXYAPATITE. DANS LA PREMIERE PARTIE, L'AUTEUR REALISE UNE ETUDE BIBLIOGRAPHIQUE DESTINEE A DEFINIR LE CONCEPT D'OSTEOINTEGRATION, SES PARAMETRES BIOLOGIQUES ET SES CRITERES DE SUCCES CLINIQUE. PUIS, SONT DEVELOPPEES LES CONNAISSANCES ACTUELLES CONCERNANT L'HYDROXYAPATITE, SON APPLICATION AU DOMAINE DE L'IMPLANTOLOGIE, ET LES ETUDES CLINIQUES ET FONDAMENTALES REALISEES AVEC CE TYPE D'IMPLANTS. LA DEUXIEME PARTIE DE CE TRAVAIL CONCERNE L'ETUDE EXPERIMENTALE. CETTE ETUDE PORTE SUR L'IMPLANTATION DE 64 IMPLANTS DE TYPES DIFFERENTS, DANS LA MANDIBULE DE 8 CHIENS BEAGLE: IMPLANTS TITANE, IMPLANTS REVETUS DE FLUORHYDROXYAPATITE DE FLUOROAPATITE, ET D'HYDROXYAPATITE, D'UNE EPAISSEUR DE REVETEMENT DE 50 ET 100 MICRONS. L'ANALYSE DES RESULTATS DE CETTE ETUDE MONTRE UNE RELATION ENTRE L'AUGMENTATION ET LA MEILLEURE QUALITE DE L'OSTEOINTEGRATION, L'AUGMENTATION DE LA RESISTANCE AUX CONTRAINTES AU CISAILLEMENT, ET L'ABSENCE DE RESORPTION DU REVETEMENT. LES MEILLEURS RESULTATS POUR CES TROIS PARAMETRES SONT OBTENUS POUR LE REVETEMENT DE FLUOROHYDROXYAPATITE

This book was released on 2001 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail porte sur l'analyse des contraintes résiduelles au voisinage de l'interface entre le titane ou son alliage le Ti-6Al-4V et des revêtements d'hydroxyapatite réalisés par torche à plasma. Ces deux matériaux entrent dans la constitution de nombreuses prothèses implantaires et notamment les implants dentaires. Une étude de l'intérêt de ces matériaux pour les applications implantaires est tout d'abord présentée. Cette étude est suivie d'une caractérisation de la porosité, de la fissuration et de l'indice de cristallinité des revêtements d'hydroxyapatite avec l'influence de ces paramètres sur les propriétés mécaniques et biologiques des implants. Dans un deuxième temps, l'étude de la concentration de contraintes résiduelles à l'interface entre le titane et le revêtement d'hydroxyapatite confirme le site privilégié de rupture de l'implant par décohésion de ces matériaux au niveau de cette interface. Ces contraintes sont mises en évidence expérimentalement grâce au rayonnement synchrotron et en simulation par éléments finis modélisant la projection par torche à plasma générant des contraintes d'origine thermique. Enfin une technique de microindentation Vickers est utilisée pour déterminer la résistance à la fissuration des revêtements au voisinage de l'interface. Cette méthode permet une analyse comparative de la ténacité de diverses éprouvettes dans la zone interfaciale.

Book excerpt: Hydroxyapatite is the most widely accepted biomaterial for the repair and reconstruction of bone tissue defects. It has all the characteristic features of biomaterials, such as, biocompatible, bioactive, osteoconductive, non-toxic, non- inflammatory and non-immunogenic properties. In this book, the authors present current research in the study of the synthesis, properties and applications of hydroxyapatites. Topics discussed include nanodimensional and nanocrystalline hydroxyapatite and other calcium orthophosphates; application of biomimetic nanocrystalline apatites in drug delivery and tissue engineering; polymer matrix mediated synthesis of nano hydroxyapatite crystals; osteointegration of titanium porous implants with carbon nanocoating and hydroxyapatite particles into the pores; hydroxyapatite thin film prepared by sputtering technique for medical applications; and hydroxyapatite application in dentistry and maxillofacial surgery.

This book was released on 1996-03-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a split-mouth design, 6 implants were placed in edentulous mandibular ridges of 10 mongrel dogs after preparation of 6 cylindrical mid- crestal defects, 5 mm in depth and 10 mm in diameter. An implant site was then prepared in the center of each defect to a depth of 5 mm beyond the apical extent of the defect. One mandibular quadrant received three commercially pure titanium screw implants (3.75 x 10 mm), while the contralateral side received three titanium double plasma sprayed hydroxyapatite-coated root-form implants (3.3 x 10 mm). Consequently, the coronal 5 mm of each implant was surrounded by a circumferential surgically created defect approximately 3 mm wide and 5 mm deep. The three dental implants in each quadrant received either canine demineralized freeze-dried bone (DFDBA) and an expanded polytetrafluoroethylene membrane (e- PTFE), membrane alone, or no treatment which served as the control. Standardized radiographs were taken at one week and 4 months post-implant placement. Computer-Assisted Densitometric Image Analysis (CADIA) was performed for each of the implants. After 4 months of healing, v block sections of the mandibles were harvested for light microscopy and histomorphometric analysis.
