Viability and integrity of cell present in particulate bone collected during the preparation of the implant site: a preliminary study

2014

Aim: The aim of this study was to evaluate viability and integrity of cells (Osteoblasts and Osteocytes) present in the particulate bone (Bone Chips), obtained during the preparation of the implant site. Methods: Four patients aged between the IV and the VI decade presenting edentulous areas class III of Cawood and Howell were selected. All patients suffering from systemic and oral diseases and smoking were excluded. The surgeries were performed with the conventional technique, full-thickness flap, and the implant sites were prepared with large coils calibrated burs mounted on surgical micromotor at a speed of 600 rpm and external irrigation of saline solution previously cooled . The partic…

ImplaVis: A research and educational system for image navigated dental implantology

Evaluation of ultrasound transmission velocity and 3-dimensional radiology in different bone types for dental implantology: a comparative ex vivo stu…

2013

Objective To evaluate ultrasound transmission velocity (UTV) for assessment of mechanical bone quality, an ex vivo comparison of different bone types measured with UTV, 2-dimensional (2D) histomorphometry and with 3-dimensional (3D) radiology (cone-beam computerized tomography [CBCT], computerized microtomography [μCT]) was conducted. Study Design Clinical cortical, cancellous, and mixed bone (each n = 6) was measured via UTV (m/s), CBCT (white pixel/black pixel ratio [WP/BP]), μCT (bone volume/total volume [μBV/TV]), and histomorphometry (bone volume/total volume [hBV/TV]). UTV values were correlated with 2D-histomorphometry and 3D-radiologic results. Results For the cortical, cancellous, …

A tool in support of oral implantology

2009

Il brevetto si riferisce ad un dispositivo che trova applicazione nella tecnica “flap-less” in chirurgia impiantare (inserimento di impianti senza esecuzione di lembo chirurgico), tecnica meno invasiva e traumatica per il paziente; esso consente di: - eseguire in modo diretto e preciso la rilevazione del profilo osseo esterno del sito impiantare - determinare l’angolazione ottimale dell’asse di foratura - guidare l’operazione di fresatura secondo l’asse prescelto Il dispositivo, grazie alla sua adattabilità e modularità è utilizzabile per eseguire siti implantari sia singoli che multipli ed è adattabile a tutte le variabili anatomiche che si possono presentare, è inoltre sterilizzabile e qu…

Gender differences among professionals dedicated to Oral Implantology in Spain: An observational study.

2021

Background: Despite the development of society and the educational progress achieved at the university education level, women continue to face obstacles that hinder their professional development. This study aims to determine whether there are gender differences in a representative sample of professionals dedicated to Oral Implantology in Spain. Material and Methods: This is a cross-sectional observational study based on the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. An electronic survey consisting of two blocks of questions was sent to members of the Spanish Society of Implants. The data were analyzed using descriptive analysis. Results: A tot…

Bone Augmentation in Dental Implantology Using Press-Fit Bone Cylinders and Twin-Principle Diamond Hollow Drills: A Case Series

2009

Background: Bone transplants are mostly prepared with cutting drills, chisels, and rasps. These techniques are difficult for unexperienced surgeons, and the implant interface is less precise due to unstandardized preparation. Cylindrical bone transplants are a known alternative. Current techniques include fixation methods with osteosynthesis screws or the dental implant. Purpose: A new bone cylinder transplant technique is presented using a twin-drill principle resulting in a customized pressfit of the transplant without fixation devices and combining this with the superior grinding properties of a diamond coating. Materials and Methods: New cylindrical diamond hollow drills are used for cu…

Relevance of functional imaging in dental implantology

2018

Background Despite it is widely used in many medicine fields, the use of functional imaging to examine dental implants has not been reported in the literature. This work aimed to evaluate the relevance of functional medical imaging in oral implantology. Material and methods This single-center observational study was conducted for 6 months at the Toulouse University Hospital, France. All patients who underwent positron emission tomography with 18-fluorodeoxyglucose integrated with X-ray computed tomography (FDG PET/CT) and had dental implants were included. Metabolic activity of the peri-implant tissues was assessed qualitatively and quantitatively jointly by a nuclear physician and a dental…
