NCT07429149
This randomized clinical trial aimed to evaluate the radiographic and clinical evaluations of mandibular implant-supported overdentures supported d by two different bar materials。 Completely edentulous patients received two implants in the mandibular canine region and were rehabilitated with overdentures supported by a conventional cobalt-chromium bar and a zirconia CAD/CAM bar。 Radiographic marginal bone loss around implants, crestal bone height changes posteriorly and clinical peri-implant parameters were assessed at baseline,6 months, and 12 months to compare the performance of both bar materials。
NCT07121881
This clinical study will evaluate two types of attachment systems used to support lower dentures in patients who have lost all their lower teeth. All participants will receive dental implants in the lower jaw, and a complete denture that attaches to these implants for better stability and comfort. The study compares two options: A traditional bar attachment A bar with additional OT Equator attachments, which are designed to improve denture retention and reduce wear Each participant will receive three implants in the lower jaw, and either a bar attachment alone or a bar with OT Equator attachments will be placed. The goal is to find out which method provides better retention of the denture, causes less bone loss around the implants, has less wear on the attachment parts, and leads to higher patient satisfaction. Participants will be followed over several months. Their denture retention will be tested using a digital force meter, bone levels will be measured through radiographs, cap wear will be examined using an electron microscope, and satisfaction will be recorded using a questionnaire. This study is being conducted at Cairo University and is self-funded by the primary investigator. Participation is voluntary and does not involve any financial cost to participants.
NCT06673355
after the implants' osseointegration period (4 months), digital scans will be taken for the implant positions and the STL files will be stored and sent for the CAD software to design a full arch restoration. Two types will be constructed, Group I patients will receive porcelain fused to titanium frameworks, and Group II will receive a framework made of high-performance polymer filled with nano-zirconia and carbon. After the installation of the frameworks, the bone height changes and the wear of the occlusal surfaces will be monitored at baseline, after 6 months and 12 months post insertion.
NCT05983718
This is a randomized controlled study that aims to compare the accuracy between full-guided with guide-pin-assisted free-hand dental implant surgeries. The basis of evaluation in each case is the comparison of the preoperative digital plan with the actual postoperative status.
NCT05016401
As part of post-marketing clinical follow-up, BIOTECH DENTAL sets up the collection and evaluation of clinical data proactively with the aim of confirming the safety, performance as well as the constantly acceptable nature of the risks identified and of detecting potential emerging risks with the use of "Kontact Perio Level" implants in everyday practice.
NCT03686865
The aim of present study was to compare peri-implant marginal bone loss and soft tissues conditions around single Laser-Lok implants placed in alveolar
NCT02924142
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?
NCT01392456
The aim of the study is: 1. To validate the Romanian translation of OHIP-EDENT (Oral Health Impact Profile in Edentulous Adults), the short form of OHIP (Oral Health Impact Profile) developed by Allen and Locker for edentulous adults. The OHIP questionnaire is an efficient instrument for assessment of OHRQoL - Oral Health-Related Quality of Life. 2. To compare satisfaction of 69 fully mandibular edentulous patients rehabilitated with implant-supported overdentures with three different types of retention: Retentive Anchors, Magnets, Locator.
