NCT06764784
This study evaluates three different methods of dental implant surgery-freehand, pilot-drilled, and fully guided techniques-in patients with partial tooth loss (partial edentulism). Dental implants are widely used to restore missing teeth, but the success of these procedures depends heavily on accurate placement and surgical precision. The study involves 90 participants, divided into three groups of 30, each undergoing one of the three surgical techniques. The main goals are to compare surgery duration, implant placement accuracy, post-operative recovery, patient satisfaction, and long-term success rates. Key findings suggest that fully guided implant surgery offers the highest accuracy, the shortest recovery time, and the highest patient satisfaction. Pilot-drilled surgery also showed excellent results, providing a balance between precision and efficiency. Freehand surgery, while flexible, showed slightly lower accuracy and higher complication rates. This research aims to guide patients and healthcare providers in selecting the most suitable implant surgery method for improved outcomes and long-term success in dental care.
NCT07107464
The goal of this clinical trial is to understand how different implant neck designs and placement depths affect the surrounding bone and peri-implant tissue (the tissue around a dental implant) in adults who need implants in the back areas of the mouth (molars and premolars). The main questions it aims to answer are: Does placing implants deeper under the bone crest (subcrestally) help preserve more bone and peri-implant tissue over time? Do implants with longer, conical necks and micro-threaded surfaces result in more stable peri-implant tissue than implants with shorter necks? Researchers will compare three types of one-piece dental implants with different neck heights (short, standard, and long), placed at different depths in the jawbone, to determine which combination better maintains bone and peri-implant tissue levels. Participants will: Receive two dental implants in the posterior upper or lower jaw Be randomly assigned to one of three groups depending on implant neck design and placement depth Undergo implant surgery using a digital workflow, with healing over three months Be rehabilitated with custom zirconia bridges Return for regular clinical and imaging checkups over a period of at least 3 years This study aims to generate evidence that helps clinicians choose implant designs and techniques that promote long-term peri-implant tissue health.
NCT07065487
This clinical trial aims to compare three different impression techniques used to fabricate full-arch implant-supported dental prostheses. Accurate impressions are essential to ensure a passive and precise fit of the final prosthetic framework, which contributes to long-term implant success and patient comfort. In this crossover study, participants with four osseointegrated dental implants in the lower jaw will undergo three types of impressions: Conventional splinted impression using polyvinyl siloxane (PVS) material. Standard digital impression using an intraoral scanner. Geometric pattern-assisted digital impression, which incorporates a visual reference pattern to improve scan alignment and accuracy. Each participant will receive all three impression techniques in a randomized sequence, at different time points. The accuracy of each method will be assessed by evaluating the passivity of the resulting prosthetic frameworks using two methods: (1) digital superimposition analysis to measure three-dimensional (3D) spatial deviation, and (2) the clinical "one-screw test" to detect misfit. The study seeks to determine whether digital scanning, particularly with geometric pattern assistance, can provide accuracy comparable to or better than conventional methods. Findings may guide improvements in digital prosthodontic workflows and support more efficient, predictable treatment outcomes.
NCT06947070
Patient attending the Outdoor Patient Department of the Department of Prosthodontics at Post Graduate Institute of Dental Sciences, Rohtak will be screened. The screening will include history taking and clinical examination of the partially edentulous patients. Patients will be selected according to the inclusion and exclusion criteria. Single stage endosseous implants will be placed. Two different Biocompatible 3D printed Polymethyl methacrylate resin will constitute two groups, Group A and Group B. 3D printed provisional poly methyl methacrylate resin crowns will be fabricated with Group- A and Group-B material followed by evaluation of surface topography and color stability after intraoral use.
NCT06449391
The current clinical implant techniques used include immediate implantation, early implantation, and delayed implantation. With the acceleration of the current pace of life, immediate implantation is increasingly favored by patients due to its advantages such as fewer surgeries, shorter waiting times, and less impact on aesthetics. The research group has shown that the mismatch between traditional implants and extraction sockets in immediate implantation surgery has caused some complications. Therefore, it is believed that 3D printed personalized root shaped implants with certain roughness are more suitable for use in immediate implantation surgery.
NCT04694300
This double-blind pilot study will evaluate the anti-inflammatory and analgesic effects of an over-the-counter (OTC) regimen of naproxen sodium versus acetaminophen in patients receiving one or two (adjacent) dental implants. It will also confirm that naproxen sodium in the OTC dosage range is a good alternative to immediate-release opioid formulations, which are subject to misuse, abuse and diversion in this patient population.
NCT06323993
This study retrospectively evaluated the effect of two different lateral window preparation techniques on peri-implant bone augmentation for patients who underwent lateral sinus floor elevation with simultaneous implant placement using two-dimensional and three-dimensional radiographic results, with special emphasis placed on the stability of the graft material after surgery.
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.
NCT05843526
The aim of this study was to characterize the host-related response of peri-implant soft tissue induced by 3 different materials: titanium, resin and PEEK (polyetheretherketone) on man. The primary endpoint is to asses the histological data available: Histological analyses are carried out with immunohistology (CD68, CD3, CD20, macrophages), non decalcified histology to appreciate the structure of the peri implant soft tissues (Sulcus depth, junctional epithelium, connective tissue adhesion). Moreover: scanning electronic microscope (SEM) of the experimental abutment is performed to juge the cell adhesion on the abutment surface. The secondary endpoint is to assess clinical data, radiological bone remodeling regarding the different material. The hypothesis is that resin abutment lead to more inflammation than PEEK or titanium.
NCT04950491
The aim of this randomized controlled trial was to compare PROMs in patients receiving single tooth replacement in posterior sites by s-CAIS and CIS.
NCT04343066
The aim of this prospective controlled clinical trial is to evaluate the clinical and radiographical outcomes of two implant surfaces inserted in a crest that has been horizontally augmented at least 6 months prior to the implant placement. The horizontal GBR should be done with a xenogenic graft mixed with autologous bone particles, and a collagen membrane stabilized using tacks or screws.
NCT03222219
The objective of this observational study is to evaluate the primary stability of dental implants. Clinical insertion torque data with the Implant Stability Quotient will be correlated.
NCT03915509
This randomised clinical study aims to evaluate different surfaced implants (alkali-modified surfaced implants or sand-blasted surfaced implants) stability with resonance frequency analysis(RFA).
NCT03854162
This is a prospective, adaptive, parallel study with four arms, which seeks to compare the accuracy of freehand and guided dental implantation surgeries. The basis of the comparison in each case is a digital plan, and that digital plan is compared to the actual postoperative status by computerized, three dimensional analysis.
