Filter by:This study evaluated the clinical and biochemical aspects of flap design in dental implant applications regarding implantation success and patient comfort. In this split-mouth randomized controlled clinical trial, a vertical releasing incision was made at the distal end of the crestal incision on the test side, and the control side received a crestal incision alone. Sixty-eight implants were placed in 17 patients. Peri-implant groove fluid was collected on postsurgical days 3, 7, 30, and 90; OPG and RANKL levels were assessed to determine bone formation and resorption around the implants. Cortisol levels were assessed in peri-implant groove fluid at postsurgical days 3, 7, and 14. Visual analog scale (VAS), and swelling measurements were taken postoperatively. Panoramic and periapical X-rays were obtained immediately post-surgery and at 3 months. No significant marginal bone loss difference was observed between the test and control sides at 3 months. The RANKL/OPG ratio, cortisol levels, VAS scores, and swelling scores were higher in the test vs. control sides. Overall, while the use of a vertical incision has advantages, such as increasing the visual field of the surgeon and improving the ease of the operation, this approach should be used only when necessary, given the disadvantages of increased bone resorption mediators in the peri-implant tissue and reduced postoperative patient comfort.
purpose: The primary purpose of this retrospective radiographic study were conducted to compare between milled bar and round bar for mini implant retained overdentures (IODs) on peri-implant bone changes and posterior mandibular ridge resorption .Study Design: A convenience sample of 18 completely edentulous participants were selected for this retrospective study from patients originally available at the start of the trial . The null hypothesis was that there were no significant difference between milled in and round bar attachment retained implant supported overdentures in posterior ridge resorption and peri-implant bone changes.
the study aims to investigate the clinical influence of different implant locations; lateral incisor, canine, and first premolar areas; supporting 2-implant retained mandibular over-dentures with locator attachment on prosthesis retention and peri-implant health.
This clinical study aims to evaluate the effect of using PEKK (Pekkton) framework in mandibular implant-supported complete fixed dental prostheses with All-on-four treatment concept on peri-implant tissues health
Eighteen patients will be selected from the outpatient clinic of the Prosthodontic Department, Faculty of Dentistry, Mansoura University seeking prosthetic rehabilitation. patients will be randomly divided into three groups according to the framework materials: PEEK, Soft metal, and selective laser melting construction.
This study will aim to evaluate the effect of two different implant positions, lateral incisors, and canine areas, on anterior and posterior ridge resorption and bone remodeling after different periods of denture insertion.
This study was conducted to evaluate the clinical peri-implant soft tissue changes during the first year after occlusal loading and the ridge base relation after 3 years for mandibular computer-aided design and computer-aided manufacturing (CAD/CAM) screw-retained implant-supported hybrid prosthesis of polyetheretherketone (PEEK) framework utilized with All-on-Four treatment concept.
The risk of Schneiderian membrane perforation and the postoperative complications of the sinus floor elevation surgery were evaluated for patients with and without history of COVID-19 infection.
This study was conducted to radiographically evaluate peri-implant and alveolar bone height changes of locator attachments used for three implant assisted mandibular complete overdenture using two different pick up protocols.
Objectives: evaluate the success rate, prosthetic maintenance , clinical and radiologic results of vertical implants with straight abutments versus inclined implants with angled abutments to retain locator maxillary overdentures. There were two groups : 1) The control group 2) The study group
