Surgical techniques for maxillary bone grafting - literature review
Faverani,Leonardo Perez; Ramalho-Ferreira,Gabriel; Santos,Paulo Henrique Dos; Rocha,Eduardo Passos; Garcia Júnior,Idelmo RangelFor oral rehabilitation with implant-supported prostheses, there are required procedures to create the bone volume needed for installation of the implants. Thus, bone grafts from intraoral or extraoral donor sites represent a very favorable opportunity. This study aimed to review the literature on the subject, seeking to discuss parameters for the indications, advantages and complications of techniques for auto...
Periodontal ligament influence on the stress distribution in a removable partia...
Archangelo,Carlos Marcelo; Rocha,Eduardo Passos; Pereira,João Antônio; Martin Junior,Manoel; Anchieta,Rodolfo Bruniera; Freitas Júnior,Amilcar ChagasOBJECTIVES: The non-homogenous aspect of periodontal ligament (PDL) has been examined using finite element analysis (FEA) to better simulate PDL behavior. The aim of this study was to assess, by 2-D FEA, the influence of non-homogenous PDL on the stress distribution when the free-end saddle removable partial denture (RPD) is partially supported by an osseointegrated implant. MATERIAL AND METHODS: Six finite ele...
Influence of high insertion torque on implant placement: an anisotropic bone st...
Sotto-Maior,Bruno Salles; Rocha,Eduardo Passos; Almeida,Erika Oliveira de; Freitas-Júnior,Amilcar Chagas; Anchieta,Rodolfo BrunieraThe aim of this study was to evaluate the influence of the high values of insertion torques on the stress and strain distribution in cortical and cancellous bones. Based on tomography imaging, a representative mathematical model of a partial maxilla was built using Mimics 11.11 and Solid Works 2010 softwares. Six models were built and each of them received an implant with one of the following insertion torques:...
Influence of voids in the hybrid layer based on self-etching adhesive systems: ...
Martini,Ana Paula; Anchieta,Rodolfo Bruniera; Rocha,Eduardo Passos; Freitas Junior,Amilcar Chagas; Almeida,Erika Oliveira de; Sundfeld,Renato HermanThe presence of porosities at the dentin/adhesive interface has been observed with the use of new generation dentin bonding systems. These porosities tend to contradict the concept that etching and hybridization processes occur equally and simultaneously. Therefore, the aim of this study was to evaluate the micromechanical behavior of the hybrid layer (HL) with voids based on a self-etching adhesive system usin...
Localized mechanics of dentin self-etching adhesive system
Anchieta,Rodolfo Bruniera; Rocha,Eduardo Passos; Ko,Ching-Chang; Sundfeld,Renato Herman; Martin Junior,Manoel; Archangelo,Carlos MarceloThe bond strength of composite resins (CRs) to dentin is influenced by the interfacial microstructure of the hybrid layer (HL) and the resin tags (TAG). The contemporary self-etching primer adhesive systems overcame the inconvenient of the etch-and-rinse protocol. Studies, however, have demonstrated that HL thickness and TAG length vary according to the wetting time and additional use of acid-etching prior to s...
