Patient data required for treatment, including images mandibles CBCT scans virtual models soft tissues teeth, were used prepare complete patient clinical conditions. saved as STL files 3D printed in...

The purpose of the present prospective, case-series study was to report implant survival rate and marginal bone remodeling expected 5 years after loading using dental implants placed in daily practice. This research designed as an open-cohort, evaluation. Any partially or completely edentulous patient, scheduled receive at least one level implant, considered eligible for this study. Primary outcome measurements were: prosthetic cumulative any complications experienced up 5-year follow-up....

Students' competency in clinical work is reached via firmly established methods, like training manual dexterity on typodonts and phantom heads. Literature suggests that virtual reality a novel teaching aid offering advantages over traditional curriculum methods. This preliminary study evaluates students' feedback Simodont® Dental Trainer. provides the familiar head environment, but with automated real-time feedback. A questionnaire consisting of single choice five-point Likert scale...

Typically, the greater atrophy of process, more extensive and invasive sinus floor elevation procedure is. This case a 39-year-old man demonstrates minimally hydrostatic lift from 1.7-mm height process in site lost tooth No. 16. Using small flap, safe drills for crestal approach diameter 2.8 mm, 2 mL saline solution under pressure syringe plunger, 1 g particulated bovine xenograft, 14-mm 12-mm width was obtained. The implant placed with torque 30 Ncm, healing cap attached. Despite very...

Restoring teeth with dental implants has become the gold standard in recent years, especially esthetic zone. However, limited amount of available bone as well interdental space anterior zone may create problems for implant treatment. Narrow diameter (NDI) be a treatment option to resolve above-mentioned limitations and providing minimally invasive therapy without additional regenerative procedures. In this retrospective study, comparison clinical radiographic outcomes between one-piece...

Background: The evolution of digital technologies, teaching techniques as well changes in the recent students generations requires adaptation and transformations to provide effective knowledge practical, manual skills dental students. Recent development implementing virtual reality (VR) simulation based training medicine revealed promising outcome. Much part education is on practice simulators different crucial quality education. Objective: goal this study was analyze students' experience...

The aim of the present in vitro comparative study is to validate a novel composite polymer, named “ONLY”, developed overcome mechanical drawbacks conventional, metal-reinforced poly(methyl methacrylate) (PMMA) interim restoration. Ten restorations were designed and fabricated (five “ONLY” group, five PMMA group). All samples screwed into prototype models, simulating complete edentulous mandible rehabilitated with six straight implants. Outcome measures break point (load, N) displacement (mm)...

The use of surgical guides provides accuracy, predictability and shortens clinical time. Templates are widely used in implant dentistry. Studies present also the application for targeted endodontic microsurgery. Nevertheless, most studies focus on one guided surgery. This case report presents single surgery implants placement, sinus floor elevation 3-in-1 was planned as an alternative to a staged approach. A 57-year-old female required microsurgery tooth 24 sites 25 26 where lift procedure...

Purpose: Cysts and other intrabony lesions can grow asymptomatic until being diagnosed by occasionally done radiologic examination. Missing tooth malposition of adjacent teeth should induce clinicians to perform X-Ray diagnostic. Methods: A 37-year-old, male patient was admitted with a hopeless 36, be extracted replaced an implant. Clinical examination revealed also missing one lower incisors remaining incisors. Cone-beam computed tomography horizontally impacted incisor surrounded bone...
