This study aimed to evaluate the most accurate impression technique for "All on Four" restoration, comparing conventional (CIG) and digital impressions (DIG).Patients randomly selected this were required be edentulous in at least one arch, presenting with severe posterior mandibular or maxillary atrophy. All patients underwent full-arch immediate-load rehabilitations, which fixed a total of four implants (two axial two tilted). Following implant placement, stratified into groups....

Abstract Background Aesthetic porcelain veneers proved to be a long-term reliable prosthetic solution, ensuring minimal invasiveness. The use of requires an adhesive cementation technique, so maintaining as much enamel possible is ensure lasting success. A diagnostic mock-up key tool that allows preview the outcome aesthetic restoration: it obtainable both in analog and digital way. With recent developments impression technology ever fast growing CAD-CAM technologies useful understand pros...

The aim of this in vitro study was to compare the quality digital workflows generated by different scanners (Intra-oral (I.O.S.s)) focusing on marginal fit analysis. A customized chrome-cobalt (Cr-Co) implant abutment simulating a maxillary right first molar fixed hemi-maxillary stone model and scanned eight I.O.S.s: Omnicam® (Denstply Sirona, Verona, Italy) CS3500®, CS3600®, (Carestream Dental, Atlanta, GA, USA), True Definition Scanner® (3M, St. Paul, MN, DWIO® (Dental Wings, Montreal,...

Purpose. Recently, the request of patients is changed in terms not only esthetic but also previsualization therapy planning. The aim this study to evaluate a new 3D-CAD-CAM digital planning technique that uses total smile process. Materials and Methods. Study participants included 28 adult dental patients, aged 19 53 years, with no oral, periodontal, or systemic diseases. For each patient, 3 intra- extraoral pictures intraoral impressions were taken. images improved from 2D Digital Smile...

Abstract Background A recent study showed that implant‐prosthetic rehabilitation in well‐controlled HIV patients gave slightly worse results than an healthy population, and failures were all linked to infection. Purpose The aim of this was examine the associations between success treatment systemic CD4 + level, smoking habits, oral hygiene. Materials Methods This mono‐centric included with a stable disease good hygiene requiring implant rehabilitation. Each patient received at least one...

The maxillary canines have long been considered critical for dental function and aesthetics, with traditional practice prioritizing their preservation alignment. However, this view often stems from outdated teachings rather than evidence-based principles, since there is no scientific support the concept of canine-protected occlusion. Therefore, commentary paper provides justification extraction severely impacted first premolar substitution. In cases canines, orthodontic alignment may be...

Gingival recession occurrence is highly prevalent after orthodontic treatment, and keeratinised tissue width at baseline significantly correlated with the prevalence, extension, severity of gingival recession, clearly demonstrating importance evaluating periodontal factors in planning treatment.

Aim: Class II Division I malocclusion poses significant challenges in orthodontics. The combination of a Herbst appliance and miniscrew anchorage emerged as practical solution to improve skeletal dental outcomes. This study employed finite element analysis evaluate the biomechanical effects miniscrew-supported on mandibular advancement dentition movement. Methods: High-definition CBCT scans captured maxilla mandible’s detailed anatomy. were stored DICOM format for seamless integration with...

The clinical trial aimed to evaluate the survival of implant-prosthetic rehabilitation in controlled HIV-positive patients.This mono-centric study included HIV patients with a stable disease, requiring implant rehabilitation, good oral hygiene. Each patient received at least one dental implant. After 90 days upper jaw and 60 lower jaw, appropriate prosthesis was delivered.Primary outcome measures were prosthetic failures, peri-implant marginal bone level changes (MBLCs), biological...

The aim of this study was to evaluate the survival and success screw-retained versus cement-retained implant restorations in immediately loaded implants at 8-year follow-up.Patients who were scheduled for full-arch ceramic prosthetic divided into two groups by randomization: one group, frameworks screwed onto (screw-retained SRG), second cemented on abutments (cement-retained CRG). Dental placed both postextraction healed sites. A temporary prosthesis after placement. Intraoral digital...

The aim of this study was to assess the accuracy digital impressions for "all-on-four" implant rehabilitation.Patients edentulous in one or both jaws were randomly selected study. Complete arch immediately loaded prostheses supported by 4 implants (2 axial and 2 tilted) placed. Five hours after placement, screw-retained full-arch temporary positioned. After months, a scan body used finalize definitive prosthesis. Radiographic assessments obtained surgery at each follow-up visit. Bone level...

This randomized-controlled trial studied the efficacy of palifermin, administered as a dose during hematopoietic stem cell transplant (HSCT) therapy, primary prophylaxis on pediatric patients with acute lymphoblastic leukemia in order to reduce oral mucositis (OM). Patients palifermin group were randomly assigned receive 60 μg/kg, intravenously single 3 days before and 0, +1, +2 post autologous HSCT infusion. The control received only placebo treatment. OM-related assessments WHO...

Aim Chlorhexidine (CHX) is commonly used in clinical applications, including plaque control and gingivitis treatment. The im of this study was to evaluate the properties, terms control, bleeding discoloration levels, six CHX mouthwashes that differ following characteristics: concentration, presence/absence alcohol an anti-discoloration system (ADS). Materials methods A single-center, prospective, double-blind randomized trial carried out on 78 consecutive patients. Six (CHX 0.12% free;...

Abstract Background Quantitative intraoperative evaluation of bone quality at implant placement site and postinsertion primary stability assessment are two key parameters to perform implant‐supported rehabilitation properly. A novel micromotor has been recently introduced allowing measure density record insertion‐related parameters, such as the instantaneous, average peak insertion torque values, torque/depth integral. Purpose The aim this study was investigate in vivo if any correlation...

The purpose of the present study was to evaluate if presence granulation tissue in asymptomatic apical periodontitis compromised immediate implant placement.Patients requiring extraction one tooth (maxillary and mandibular incisive, canine or premolar) with periodontitis, were recruited for this prospective study. They randomly scheduled into two groups: first group (A) including 30 teeth, reactive soft debrided before placement, second (B) left lesion. Implants positioned immediately after...
