Filter by:This study is about the assessment of two oral telemedecine tools compared to an intra oral clinical examination used as a reference among elderly persons living in nursing home. Our hyposthesis is that the diagnostic performance of the two devices will be similar. The main goal of the study is to assess the performances of two intra-oral cameras compared to an intra oral clinical examination to detect at least one decayed tooth. The secondary objectives of this study are : At patient's level: 1. To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) at least one filled tooth, (ii) at least one missing tooth, (iii) gingivitis, (iv) an abscess, (v) dental plaque and (vi) calculous 2. To assess the concordance between each intra oral cameras and the intra oral clinical examination in the evaluation of the number (i) of decayed teeth, (ii) filled teeth and (iii) missing tooth 3. From video acquisitions of each intra oral cameras, to assess the inter-observer concordance for the diagnostic of each dental pathologies (presence of at least one decayed tooth, filled or missing) and periodontal (presence of gingivitis, abscess, dental plaque or scale) 4. From video acquisitions of each intra oral cameras, to assess the inter-observer agreement of the number of teeth: (i) decayed, (ii) filled and (ii) missing At tooth level : 5. To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) a cavity, (ii) a filled tooth and (iii) missing tooth In all patients : 6. To assess patient's feelings about the use of each intra oral cameras 7. To compare the time required for video acquisitions between each of intra oral cameras For patients with dental or periodontal pathologies observed during the intra oral examination: 8 To assess, 2 months after initial evaluation, the proportion of patients attended dental or periodontal care and for which an appointment with a dentist has been scheduled
This study aims to assess the treatment outcomes (clinical, functional and subjective) of full arch rehabilitations supported by implants with or without an immediate loading protocol. In this randomized clinical trial 20 fully edentulous patients were treated with full arch rehabilitations on dental implants. In half of the sample, the implants were loaded immediately by means of abutments after emplacement of the implant; but in the counterparts these abutments were connected to implants two months after the surgery (conventional protocol), and until that time the dentures were retained by healing abutments. Treatment outcomes were assessed at 2, 6 and 12 months after surgery. Clinical outcomes were quantified on the basis of implant failure rate, marginal bone loss and the peri-implant gingival index. Functional outcomes were calculated according to masticatory performance, estimated by the mixed fraction of a two-coloured chewing gum after 5, 10 and 15 chewing strokes, by the occlusal force recorded by pressure-sensitive sheets and by the bioelectrical muscular activity. The subjective outcomes of the treatment were assessed using both the oral satisfaction scale (visual analogue scale) and the Spanish version of the Oral Health Impact Profile (OHIP-20).
Intraoral oral scanning significantly improves scanning accuracy compared to digitized conventional impression techniques. The digitized closed tray impression technique showed significantly more accurate results than the digitized open-tray impression technique in partially edentulous patients.
Objective: The aim of this prospective study was to investigate the patient-reported outcome measures (PROMs) of implant-supported prostheses (ISP) among patients who had excised pathological jaw lesions. Material and Methods: Patients who met the inclusion/exclusion criteria in a dental teaching hospital were recruited. Data pertaining to sociodemographic factors, conditions requiring surgery, surgical procedures and related complications, and types of ISP were collected. Patients' expectation and satisfaction to the ISP including oral health, self-perceived appearance, speech, chewing ability, oral comfort and ease of cleaning were assessed using the visual analogue scale (VAS, 0-100) and global transitional scale/judgement (Likert scale). Data were analysed using t-test and chi-square tests at the significance level α=0.05.
Aim of the study is to examine the feasibility of dental implant insertion in patients receiving high, adjuvant and low dose > 4 years.
Approximately 40 implants from patients seeking treatment at the University of Oklahoma, College of Dentistry will be recruited for this study. Osteotomies will be prepared using the osseodensification technique and implants will be placed immediately after. The implants will be from a single manufacturer (Roxolid® SLA® Bone Level Tapered; Straumann®, Institut Straumann AG, Basel, Switzerland). Volumetric analysis of alveolar ridge will be studied using intra-surgical direct measurements and CBCT imaging. A custom stent will be fabricated to standardize the clinical and radiographic measurements at 2mm, 3mm, and 4mm apical to the alveolar crest. Changes in peri-implant bone density will be analyzed on standardized periapical and bitewing radiographs, using the ImageJ software (National Institute of Health, Bethesda, Maryland, USA). Implant stability quotient (ISQ) values will be recorded with a resonance frequency analysis system (Osstell®, Gothenburg, Sweden). Calibrated examiners will assess implant survival and biological or restorative complications and failures. Sites will be evaluated throughout osseointegration and one year after final restoration is delivered.
The aim of is to compare the survival rate and technical outcomes of cantilever implant-supported fixed denture prosthetics (cFDPs) made either out of monolithic zirconia bonded to a titanium base in a digital workflow, or porcelain fused-to metal using a gold abutment in a conventional workflow. In addition, biological outcomes, wear patterns, PROMs and time efficiency will be recorded. The null hypothesis is: the reconstruction type does not influence the survival rate and technical outcomes of 2-unit implant-supported cFDP.

This study is a clinical trial to determine the retention and durability of the anterior zirconia wing bridge. The type of zirconia-wing bridge the investigators are researching in this study has two wings which generally have three countersunk holes (meaning that the circumference of the outer portion of the hole is larger than the inner part of the hole). Composite resin (dental filling material) is placed in the holes as well as under and around the wings. Twelve patients will have bridges placed and be evaluated every 6 months (ideally) to determine if the bridge is staying in place (retention) and if it is resistant to fracture (durability).
The primary aim of this study is to introduce a new effective and efficient 3D printed design of an intra-oral space maintainer. The secondary aim of the study is to: Evaluate the clinical performance of 3D printed space maintainer versus conventional metal band and loop over a period of 6 months regarding their functional , biological aspects and patient satisfaction.
