Submicron Scale-Structured Hydrophilic Titanium Surfaces Promote Early Osteogenic Gene Response for Cell Adhesion and Cell Differentiation

2011

cid_339 166..175 ABSTRACT Background and Purpose: Titanium (Ti) surface roughness and surface hydrophilicity are key factors to regulate osteogenic cell responses during dental implant healing. In detail, specific integrin-mediated interactions with the extracellular environment trigger relevant osteogenic cell responses like differentiation and matrix synthesis via transcriptions factors. Aim of this study was to monitor surface-dependent osteogenic cell adhesion dynamics, proliferation, and specific osteo- genic cell differentiation over a period of 7 days. Materials and Methods: Ti disks were manufactured to present smooth pretreatment (PT) surfaces and rough sandblasted/ acid-etched (SL…

Early implant healing: promotion of platelet activation and cytokine release by topographical, chemical and biomimetical titanium surface modificatio…

2011

Abstract Objectives: Platelet releasate has been shown to promote osteogenetic cell proliferation and differentiation. Topography and chemistry of biomaterials have high impact on platelet activation. More specifically, the bioactive cell adhesive peptide sequence Arg–Gly–Asp (RGD) triggers platelet activation mediated by the αIIbβ3 integrin receptor. Accordingly, topographical, chemical and biomimetical (immobilized RGD peptide) modifications of titanium (Ti) surfaces may enhance early platelet activation and bony healing of implants. Therefore, the aim of the study was to evaluate platelet activation with subsequent platelet-derived cytokine release by accordingly modified Ti surfaces. Ma…

Medication-Related Osteonecrosis of Jaws (MRONJ) Prevention and Diagnosis: Italian Consensus Update 2020

2020

The Medication-Related Osteonecrosis of Jaws (MRONJ) diagnosis process and its prevention play a role of great and rising importance, not only on the Quality of Life (QoL) of patients, but also on the decision-making process by the majority of dentists and oral surgeons involved in MRONJ prevention (primary and secondary). The present paper reports the update of the conclusions from the Consensus Conference—held at the Symposium of the Italian Society of Oral Pathology and Medicine (SIPMO) (20 October 2018, Ancona, Italy)—after the newest recommendations (2020) on MRONJ were published by two scientific societies (Italian Societies of Maxillofacial Surgery and Oral Pathology and Medicine, SI…

Wie gut läßt sich der Wachstumstyp schätzen?

1990

The purpose of this study was to determine to what extent growth type can be predicted using different information. Correlations between estimated values and those measuring cephalometric growth indicators revealed that the growth type can be evaluated reasonably well by merely viewing the cephalogram. The viewer is guided by form which is represented by the Go2 angle according to Jarabak. Growth type can also be evaluated from a profile photography. The assessment can be improved if one uses a wooden spatula to determine the mandibular and occlusal planes.

Systemic risk factors for peri-implant bone loss: a systematic review and meta-analysis

2014

The aim of this study was to determine the influence of patient-related systemic risk factors (systemic disease, genetic traits, chronic drug or alcohol consumption, and smoking status) on peri-implant bone loss at least 1 year after implant installation and prosthetic loading. An electronic search was performed of MEDLINE, EMBASE, and The Cochrane Central Register of Controlled Trials up to January 2012. One thousand seven hundred and sixty-three studies were identified. After applying a three-stage screening process, 17 articles were included in the qualitative analysis, but only 13 in the quantitative analysis, since smoking was a common exposure. The meta-analysis of these 13 studies (4…

Patient-centered outcomes after surgical treatment of peri-implantitis: a prospective clinical study.

2022

Background: Peri-implantitis is an inflammatory process affecting soft and hard tissues surrounding dental implants, causing progressive marginal bone loss. Peri-implant surgery is the treatment of choice. However, evidence about its impact on patients' quality of life (QoL) is limited. This study aimed to assess pain and QoL in the first seven post-operative days and measure patient satisfaction at the end of this period. Material and methods: A prospective cohort study was conducted in patients with peri-implantitis. Patients reported pain on a visual analogue scale (VAS) ranging from 0 to 100mm every day during the first week after surgery. They then completed the OHIP-14sp questionnaire…

Quando bisogna discostarsi dalle linee guida? I casi problematici nella prassi odontoiatrica

2018

Obiettivi Delineare vantaggi e limiti delle linee guida e dei riferimenti alle buone pratiche nella valutazione della condotta professionale dell’odontoiatra. Definire tipologie di pazienti e contesti operativi nei quali esse non risultano applicabili. Quest’obiettivo è coerente con i recenti sviluppi giurisprudenziali della Corte di Cassazione a Sezioni Unite del dicembre 2017 in tema di colpa e responsabilità dei sanitari. Materiali e metodi Si analizzano i riferimenti contenuti nella Legge 24/2017; quindi, in riferimento alla metodologia della responsabilità medico/odontoiatrica, si individuano i contesti della pratica clinica nei quali è più opportuno cercare di sviluppare buone pratich…

Root repair after injury from mini-screw

2005

Mini-implants and mini-screws are commonly used in orthodontics to provide extra anchorage. One potential insertion site is between the roots in the alveolar process, which results in a risk of damaging the roots of neighbouring teeth. In an animal-experimental study, 20 mini-screws (bracket screw bone anchors, BSBAs) were inserted into the mandible of five beagle dogs. Each dog received two BSBAs in each lower quadrant, between the roots of the second and third, and third and fourth premolars. Sequential point labelling was performed every 6 weeks with vital stains, and apical X-rays were taken every 6 weeks. Radiographic examination demonstrated damage at three roots because of insertion …

Is the Erich arch bar the best intermaxillary fixation method in maxillofacial fractures? : a systematic review

2015

Background Intermaxillary fixation is used to achieve proper occlusion during and after oral and maxillofacial fracture surgery. The aim of this systematic review was to compare Erich arch bar fixation with other intermaxillary fixation methods in terms of the operating time, safety during installation, oral health maintenance and occlusal stability. Material and Methods An electronic online search was conducted of the Scirus, PubMed, Ovid, Cochrane Library and VHL databases. A clinical trial dating from the inception of the data bases until August 2013 was selected. Studies that compared Erich arch bars with other intermaxillary fixation methods in patients older than 18 years-old were inc…
