Active clinical trials for "Mouth, Edentulous"

Evaluation of the muscle activity of masseter in tooth borne partial denture wearers (class III modification 1 Kennedy's classification) with two different denture base materials (Breflex and PEEK) by means of electromyograph.

Steps in short: Undergoing the conventional steps of maxillary single denture construction till the step of framework construction that will be designed and constructed using CAD/CAM after optical scanning of the master cast ( 2 frameworks to cover the palate and crest of the ridge : one made of titanium and the other made of cobalt/chromium) then conventional steps will be undergone including bite, Try-in and delivery ending by measuring the denture retention. Number of visits & follow up period : Visits: will be 5-6 visits for each patient. Follow up period: 6.5 months (immediately post-insertion then after 1 week then after 3 months for the first type then 2 weeks washout period and the same for the second type)

Patients were randomly divided in to two groups by using computerized software ; the first group received flat magnetic attachment design while the second group received dome magnetic attachment design.which the inclusion criteria is completely edentulous patient ,Age range from 40 to 70 year old ,skeletal class 1, both sexes Implant stability will be measured for both groups using smart peg /osstell at the day of implant installation and after 2,4,8,12 weeks. Patient satisfaction measure in 2 weak and after 12 weak by Denture satisfaction questionnaire

the purpose of this study is to clarify the rationale for the choice of the upper or lower jaw for positioning the occlusal splint

The device under investigation is SYNERGOSS, a CE (European Community CE) marked device. Synergoss is a granulated bone graft intended for use in dental applications. It is composed of a ceramic composite of Hydroxihapatite and Tricalciumphosphate in granules, coated with a dedicated collagen coating (porcine origin), obtained by means of collagen crosslinking on the ceramic granule surface. The purpose of the study is to confirm the foreseen efficacy and tolerability of SYNERGOSS, a synthetic dental graft coated with collagen. For this observational study, we will enroll patients that already received a surgical intervention for sinus augmentation/ socket preservation by means of SYNERGOSS to maintain and regenerate bone before installation of endosseous titanium implants to support a fixed prosthesis. Patients will be enrolled just before they receive the surgery for the installation of endosseous titanium implants, about 24 weeks after the first surgery for the implant of SYNERGOSS. The primary hypothesis is to demonstrate that SYNERGOSS consistently obtains the foreseen clinical benefit as declared in the Technical File. The secondary hypothesis is to demonstrate that SYNERGOSS side effects and risks match those declared in the Technical File. The study design is a National Monocentric Prospective: the participants are identified and then followed forward in time. Observational: participants that have recently received the grafting with SYNERGIES as part of normal and foreseen clinical procedures are enrolled in the study when they receive surgery for titanium implant placement and observed over time, with no substantial intervention other than the foreseen clinical treatment

This investigation is undertaken to evaluate the workflow and concomitant products to create full dentures by using Additive Manufacturing (AM) technology, i.e. Digital Light Processing™ Technology (Carbon 3D) to restore fully edentulous jaws. The assessment includes quality of materials provided by Dentsply Sirona Lab by using printers for Additive Manufacturing (M2 series, Carbon 3D 1089 Mills Way, Redwood City, CA 94063). This assessment will be done by clinical review of the AM dentures on fit and quality. In addition, the trial includes a patient survey to assess current dentures and the new AM dentures with a subjective comparison of both.

Tooth loss impact on daily living, mood and self-perceived well-being. However, psychological impact of teeth loss has not been evaluated. Present study aims to evaluate the psychological conditions of patients pending complete tooth extraction before and shortly after tooth loss using Hospital Anxiety and Depression scale (HAD) and Geriatric Oral Health Assessment Index (GOHAI).

The purpose of this study is to evaluate the clinical results of implant-retained mandibular overdentures in edentulous patients.

Osseointegrated root form implants have been applied successfully in treating fully and partially edentulous patients and patients with single tooth missing. However, the success rate of osseointegrated dental implants was not as good in patients with poor bone quality. The reasons are believed that poor bone quality reduces the initial stability of dental implants and then reduces the success rate. For increasing initial stability of dental implants, some technical modifications are suggested in literature. However, due to lack of an objective method to evaluate bone quality, they are controversial. The purposes of this clinical study are to develop a standard procedure which using cutting resistance measured by Osseocare in surgery to evaluate the bone quality and to compare with the clinical experiences of oral surgeons. The objective outcome, initial stability of dental implant, is measured with Osstell. The analyzed results are also helpful for less experienced surgeons.

16 implant placement by surgical guide using double scan protocol versus triple scan protocol to Evaluate angular and linear deviation of virtual implants and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .
