Active clinical trials for "Mouth, Edentulous"

Forty completely edentulous patients were selected and randomly distributed into two groups 20 patients each.Group I received complete dentures constructed from elastomeric impression with wax spacer,group II received complete dentures constructed from elastomeric impression with no wax spacer.then on time of denture insertion pressure areas were detected using pressure indicating paste and the denture retention was detected.The results showed less pressure areas in group I and more denture retention values than group II.

The study will compare between osteotome technique and New Reverse Drilling Technique in the placement of dental implant in posterior maxilla , primary outcome will be Implant stability that will be measured by Periotest device . follow up for 6 month. secondary outcomes will be crestal bone loss , pain and swelling.

PICOTS: P: Kennedy class І patients I : Mandibular removable partial denture with OT Cap attachment C: Mandibular removable partial denture with gingival approaching clasp assembly O: 1ry outcome: Oral Health Related Quality of Life 2ry outcome: Biting force T: 1 Year S : Randomized control trial Research question: In Kennedy class І patients will the removable partial denture with OT Cap attachment compared to conventional removable partial denture with clasp assembly results in difference in Oral Health Related Quality of Life of Patients?

The purpose of this study is to compare the regenerative results of using separately two different xenografts after two-step sinus floor elevation.

Twelve participants with edentulous alveolar crests in the distal portion of the arches will be included in the study. At least two implant sites will be identified in each patient and will be sub-prepared with drills or sonic instruments. One site will be used as a test and one as a control where experimental mini-implants will be installed. Reconstructive surgical procedures will be applied at the biopsy sites.

A multicenter prospective observational study in which aim is to illustrate the clinical outcome of dental implants "Kontact N"; and the effects of its nanostructured surface on the osseointegration and secondary stability without increasing the rate of peri-implantitis. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.

Purpose: To determine if adjustment of full-arch zirconia frameworks processed on a model obtained with an intraoral scanner and an auxiliary device is not inferior to that of identical frameworks obtained from an elastomeric impression. Materials and methods: Eight consecutive patients ready for a full-arch rehabilitation on already osseointegrated implants were selected. Two sets of impressions were taken, one open tray with polyether and splinted impression copings and a second one with an intraoral scanner. A verification plaster jig was used for the elastomeric impression and a prefabricated auxiliary device was used to adjust the optical intraoral impressions. Two full-zirconia frameworks with the same design were processed and tested on the patient by two independent calibrated operators. Accuracy of both frameworks was measured by calibrated blinded operators, who determined tactile adjustment, Sheffield test, radiographic adjustment, and screwing torque. Overall perception of adjustment was used to determine the better framework to be delivered to the patient. Hº: Frameworks obtained from an impression taken with an intraoral scanner are not inferior in accuracy to those obtained from a conventional elastomeric impression

Acqua GM (Grand Morse) Helix implants present an optimized implant design with adapted treatment protocol, allowing for treatment of patients with different bone qualities. The objective of the study is to prospectively collect clinical data to confirm the long-term safety and clinical performance of Acqua GM Helix implants and GM prosthetic abutments in daily dental practice setting, by means of success and survival rates of these devices. Devices will be used according to standard routine in daily practice, according to all indications as specified by the manufacturer in the IFU (instructions for use). patients will be followed for 36 months after implant placement.

A prospective observational study guided by the guidelines of Strengthening The Reporting Of Observational Study in Epidemiology (STROBE) in 2014, that will be conducted to evaluate implant stability using three devices; Osstell®, Peiotest® and AnyCheck® and comparing the results.

Objectives: The purpose of this study is to evaluate bite force (BF), oral health-related quality of life (OHRQoL), and patient satisfaction in 2-implant-supported overdentures. In addition, the effects of clinical parameters such as age, gender, implant length, implant diameter, locator attachment height, attachment color, and interimplant distance were also evaluated. Material and Methods: A total of 51 patients were included in the study. BFs were measured with a force meter in complete dentures and implant-supported overdentures. OHRQoL was assessed with the Oral Health Impact Profile (OHIP-14) and patient satisfaction was assessed with the Visual Analog Scale (VAS).
