Dental implants are one of the most commonly used ways to replace missing teeth. Nevertheless, close contact with hard and soft oral tissues expose these devices infectious peri-implant diseases. To prevent such infection, several surface treatments have been developed in last few years improve antimicrobial properties titanium dental implants. In this in-vitro pilot study, activity surfaces coated different types graphene nanoplatelets investigated. Six colloidal suspensions (GNPs) were...

Abstract Objectives to retrospectively evaluate clinical and radiographic outcomes of immediate, flapless full‐arch prostheses, supported by 4/6 implants according prosthetic‐driven planning guided surgery. Materials Methods The study involved 28 edentulous patients (20 female/8 males; average age 67.75 ± 8.627 years), 32 prostheses (17 all‐on‐4/15 all‐on‐6) 164 implants. Implants survival, success/survival, peri‐implant marginal bone loss, incidence biological prosthetic complications were...

Background: Implant surgical guides manufactured in-house using 3D printing technology are widely used in clinical practice to translate virtual planning the operative field. Aim: The present vitro study investigated dimensional changes of printed Shining guide resin (SG01). Materials and methods: Five test bodies, varying shape dimensions, were designed computer-aided design (CAD) software three different Light Crystal Display (LCD) printers (AccuFab-L4D, Elegoo Mars Pro 3, Zortrax...

Objectives . To evaluate the performances of six different bone substitute materials used as graft in maxillary sinus augmentation by means histological and histomorphometric analysis biopsies retrieved from human subjects after a 6-month healing period. Materials Methods Six consecutive patients (3 males, 3 females, aged 50-72 years), healthy, nonsmokers, with good oral hygiene, presenting edentulous posterior maxilla residual crest measuring ≤ 4 mm vertical height to 5 horizontal thickness...

The aim of this survey was to evaluate the knowledge and awareness parents about potential oral health risk factors correct management hygiene their preschool children.The participation proposed all 3-5 year aged children attending a kindergarten in Campobasso. A self-administered questionnaire completed obtain information regarding demographic education variables, caries its transmission, infant feeding practice, maternal during pregnancy, children's habits behaviors (e.g., sharing cutlery,...

The use of digital devices is strongly influencing the dental rehabilitation workflow both for single-crown and full-arch prosthetic treatments.In this study, trueness was analyzed by overlapping scan dataset made with Medit I-500 (by using two different tips strategies) lab scanning, values (90°-10°)/2 method were reported. Precision evaluated same coming from intra-group (scan an IOS overlapped compared to each other). Moreover, software programs used calculate accuracy values.The mean...

Objective . The aim of this study was to validate the role diffusion-weighted imaging (DWI) at 3 Tesla in differential diagnosis between benign and malignant laterocervical lymph nodes patients with head neck squamous cell carcinoma (HNSCC). Materials Methods Before undergoing surgery, 80 patients, biopsy proven HNSCC, underwent a magnetic resonance exam. Sensitivity (Se) specificity (Spe) conventional criteria DWI detecting node metastases were calculated. Histological results from...

Surgery to the mandibular third molar is common, and injuries inferior alveolar nerve lingual are well-recognized complications of this procedure. The aim these technical notes describe operative measures for reducing neurological during surgery. following procedure should be used prevent damage nerve: a well-designed mucoperiosteal flap, obtain appropriate access surgical area; conservative ostectomy on distal distal-lingual side; tooth sectioning, facilitate its removal by decreasing...

Computer aided implantology is the safest way to perform dental implants. The research of high accuracy represents a daily effort. validated method assess placed implants superimposition pre-operative and post-operative cone beam computed tomography (CBCT) with planned This procedure accountable for biologic cost patient. To investigate alternative assessment, fifteen resin casts were printed. For each model, six digitally then following three different approaches: (a) template guided free...

To evaluate the effect of orthodontic stainless steel brackets and two different types archwires on diagnostic quality 3-T MR images.This prospective, case-control study was conducted following Strengthening Reporting Observational Studies in Epidemiology guidelines. The recruitment among patients. 80 subjects, requiring MRI for presence temporomandibular disorders, were enrolled divided into four groups: 20 patients using aligners (control group); with without archwires; nickel-titanium...

Abstract Background Over the years, only few authors have studied association of systemic conditions with peri‐implantitis. The aim this study is to detect frequency and severity peri‐implant diseases among an Italian population patients affected by metabolic syndrome (MetS). Methods In cross‐sectional study, at least one dental implant >5 years functional loading were screened evaluate metabolic, periodontal, status. MetS diagnosis was established in accordance National Cholesterol...

Pterygoid implant placement has not been a common treatment modality to manage the atrophic posterior maxilla. This randomized, controlled clinical trial evaluated accuracy of dynamic navigation using trace registration (TR) technology in pterygoid when compared free-hand surgery. Partially edentulous patients requiring at least one rehabilitate maxilla were included. Implant (in prosthetically directed context) and relation placed implants greater palatine canal (GPC) EvaluNav compare...

A minimally invasive implant treatment approach for future full arch prosthetic rehabilitations of trophic jaws represents a challenge. An optimal planning is strongly related with an accurate merge the information and radiographic data. To comply that, most computer aided implantology (CAI) systems require additional steps, as stents or fiducial markers to overlap digital jaw scans cone beam computed tomography (CBCT) Using dynamic CAI, residual teeth (up three) make it possible avoid new...
