As perdas dentárias na região anterior da maxila constituem um grande desafio nas reabilitações implantossuportadas. Quando fatores locais adversos inviabilizam a implantação imediata, a atrofia óssea acontece de forma fisiológica, progressiva e irreversível, uma vez que a manutenção do arcabouço de tecidos duros e moles são dependentes da presença...

Acetylsalicylic acid (ASA) is commonly used as a non-steroidal anti-inflammatory drug that interferes with multiple biological pathways. ASA acts by stimulating osteogenesis and inhibiting osteoclastogenesis. Thus, the objective of this study was to perform a systematic review and meta-analysis to evaluate the effectiveness of the use of ASA in the...

A colocação de implantes na maxila apresenta particularidades diferentes das encontradas na mandíbula. Um dos desafios da instalação dos implantes mais freqüente é a atrofia da maxila após a perda parcial ou total das unidades dentárias. Como resultado há uma diminuição significativa na altura e volume do osso disponível na região posterior da maxi...

Background In recent years, the number of procedures for buccal fat pad removal has increased. In cases of thinning of the face, bite injuries or bruxism, partial removal of the corpuscle is performed, always taking into account facial harmonization.

The keratocyst is a rare development cyst with high destructive power and can reach large dimensions and a high rate of recurrence. Most of this injury affects men aged 20 to 40 years, affecting the posterior region of the mandible. It can be asymptomatic when in small dimensions even with slow growth, the diagnosis can often be observed in radiogr...

Rehabilitation with osseointegrated implants is a therapeutic option consolidated in the literature and has a high rate of success and predictability. However, the loss of dental elements leads to tissue collapse that often make the installation of dental implants unfeasible, causing atrophic defects in the jaws of varying magnitudes. The objective...

Dental implant surgery is a common procedure in oral and maxillofacial surgery practices. Extensive training, skill, and experience allow this procedure to be performed with an atraumatic approach, but like any surgical technique, it is subject to accidents and complications. This is an unusual clinical case of an accidental displacement of an impl...

The periodontal ligament (PDL) and alveolar bone are two critical tissues for understanding orthodontic tooth movement. The current literature is replete with descriptive studies of multiple cell types and their matrices in the PDL and alveolar bone, but is deficient with how stem/progenitor cells differentiate into PDL and alveolar bone cells. Can...

Surface topography modifications have become a key strategy for hastening the host-to-implant response to implantable materials. The present study evaluated the effect of three different carefully controlled surface texture patterns achieved through microrobotized blasting (controlled to high, medium and low roughness) relative to a larger scale bl...

The objective of this study was to assess the bone repair process of crystallized Biosilicate in surgically created defects on rats' calvaria. This biomaterial was recently developed for odontological use. We used fifteen rats (rattus norvegicus albinus, Wistar), and two 5 mm surgical defects were performed on each of them; the defects were made wi...

Dentin in permanent teeth rarely undergoes resorption in development, homeostasis, or aging, in contrast to bone that undergoes periodic resorption/remodeling. The authors hypothesized that cells in the mesenchymal compartment of dental pulp attenuate osteoclastogenesis. Mononucleated and adherent cells from donor-matched rat dental pulp (dental pu...

The aim of this study was to perform a histomorphometric evaluation of the repair process in rat teeth replanted after root canals were filled with calcium hydroxide (CH) and mineral trioxide aggregate (MTA).

Resumo Introdução: As injúrias mandibulares correspondem a cerca de 20% a 50% dos casos de fraturas faciais. Alguns consideram a mandíbula o segundo osso do crânio mais fraturado, além de ser o único osso móvel do arcabouço facial, o que resulta na diminuição da estabilidade frente ao trauma. Quando se leva em consideração a obstrução de vias aérea...

Dental injuries are often the result of direct trauma. The most affected teeth are the upper incisors, and the most frequent lesions are coronal fractures, contusions, and lip and alveolar mucosa lacerations. The objective of this study was to draw attention to the importance of the correct management of cases of crow fractures associated with soft...

Abstract -  Dental tissues have special characteristics, and its regenerative capacity is noteworthy. However, understanding the circumstances that lead to regeneration is challenging. In this study, the chronology of the healing process after immediate replantation of rat incisor teeth was examined by histological and immunohistochemical analyses...

Clinical experience has shown that most avulsed teeth are replanted after a long extra-alveolar time and dry or inadequate wet storage, causing necrosis of periodontal ligament cells. This condition invariably leads to development of external root resorption, leaving the filling material in contact with the periapical connective tissues. In this st...
