Clinical Safety and Effectiveness of the Straumann Dynamic Navigation System Falcon

The Falcon Study is a prospective, multicenter, multinational clinical investigation evaluating the Straumann® Dynamic Navigation System (Falcon) for dental implant placement. The Falcon system is a real-time dynamic navigation device that helps clinicians visualize the position of dental instruments during surgery. The purpose of the study is to assess whether Falcon enables safe and precise implant placement in partially edentulous patients compared to benchmarks from the literature for freehand implant placement. The study will enroll approximately 75 adult patients across four European centers (Switzerland, Italy, the Netherlands, and Belgium). Each patient will undergo preoperative planning, implant surgery with the Falcon system, and a postoperative cone beam computed tomography (CBCT) scan to measure implant placement accuracy. The main outcomes are (1) angular deviation between planned and actual implant position, and (2) safety as measured by adverse device effects. Results will provide clinical evidence to support regulatory clearance and the safe adoption of the Falcon system in routine practice.

To Compare the Two Implant Placement Protocols to Evaluate Placement Accuracy and Post-operative Healing of the Implant

The goal of this study is to evaluate two commonly utilized surgical guide protocols to determine dental implant placement accuracy compared to pre-operative computerized planning, post-operative healing and bone levels to 12-months post-placement, and patient assessed post-operative discomfort and healing using a visual acuity scale (VAS).

Effect of Local Application of 1% Metformin Gel on Implant Stability and Peri-implant Bone Density: A Randomized Controlled Study

This randomized controlled clinical study aims to evaluate the effect of local application of 1% metformin gel on implant stability and peri-implant bone density. Patients requiring dental implants will be randomly allocated into two groups: a control group and a test group receiving metformin gel. Implant stability will be assessed using resonance frequency analysis, and bone density will be evaluated using CBCT imaging. The outcomes will be compared over a follow-up period to determine the effectiveness of metformin in enhancing osseointegration

Hard Tissue Augmentation With or Without Connective Tissue Graft in Immediate Esthetic Implants

This randomized controlled study is aimed to evaluate the esthetic, clinical, and radiographic outcomes following the placement of immediate single-tooth implant with hard and soft tissue augmentation. Subjects will randomly assigned to one of two groups: * Group A (control group) receiving an immediate single-tooth implant in the esthetic zone with bone augmentation only. * Group B (study group) receiving an immediate single-tooth implant in the esthetic zone with bone augmentation and connective tissue graft (CTG). The main questions it aims to answer is: Is there is a significant difference in the esthetic outcome between bone augmentation alone and bone augmentation combined with connective tissue graft after immediate dental implant in the esthetic zone?

Artificial Intelligence-Guided Versus Manual CBCT Planning for Immediate Implant Placement

This study evaluates whether artificial intelligence (AI)-based analysis of cone-beam computed tomography (CBCT) scans can support clinical decision-making for immediate dental implant placement in molar extraction sites. When a molar tooth is removed, placing a dental implant immediately may reduce treatment time and preserve surrounding bone. However, immediate implant placement is not always possible and depends on the anatomy of the extraction socket, particularly the interradicular septum (the bone between the roots). CBCT imaging is routinely used to assess this anatomy before surgery. Traditionally, radiologists manually evaluate these scans. Recently, AI-based tools have been developed to automatically analyze CBCT images. In this randomized controlled trial, patients requiring molar extraction and potential immediate implant placement will be assigned to one of two planning approaches: AI-guided CBCT assessment or conventional manual CBCT assessment. The operating surgeon will use the assigned planning report to guide treatment decisions. The primary outcome of the study is the feasibility of immediate implant placement, defined as successful implant placement with achievement of primary stability during surgery. Secondary outcomes include surgical time, need for changes to the treatment plan, and implant stability measurements. The goal of this study is to determine whether AI-assisted CBCT analysis performs similarly to, or improves upon, conventional manual radiologic assessment in supporting safe and effective immediate implant placement.

Comparative Evaluation of Xenograft Alone and Sticky Bone in Sinus Lift With Concurrent Implant Placement

Introduction \& Background: Modern dental implantology offers solutions for patients with edentulism in the maxillary arch, where sinus pneumatization and alveolar ridge atrophy are common conditions. This often requires sinus floor elevation and bone grafting prior to implant placement. Techniques such as the lateral window approach and osteotome-mediated sinus floor elevation aim to achieve sufficient vertical bone height for successful implant placement. Autogenous bone grafts have long been considered the gold standard; however, their use is associated with limitations including donor site morbidity and graft volume loss, which has encouraged the exploration of alternative grafting materials. Sticky bone is a term used in oral surgery and implantology to describe a cohesive, moldable, and adhesive bone graft material prepared by combining particulate bone graft material (xenograft) with biological additives such as Platelet-Rich Plasma (PRP) or Platelet-Rich Fibrin (PRF). Platelet-Rich Fibrin (PRF), which is used in the present study, is an autologous leukocyte and platelet-rich fibrin matrix containing cytokines, platelets, and stem cells. PRF acts as a biodegradable scaffold that promotes microvascularization and guides epithelial cell migration. In addition, PRF may serve as a carrier for regenerative cells and allows sustained release of growth factors over a period ranging from one to four weeks, thereby enhancing the wound healing environment. Objectives: The study aims to assess the clinical efficacy of sticky bone as a bone graft material in sinus lift procedures compared with conventional xenograft materials. Methods: A randomized clinical trial will be conducted comparing two groups: one receiving sticky bone with simultaneous implant placement and another receiving xenograft with implant placement. Preoperative assessment will include Cone Beam Computed Tomography (CBCT) imaging, followed by postoperative monitoring to evaluate bone height and implant stability. Study Design: Patients fulfilling the inclusion and exclusion criteria will be recruited from the dental clinic. Written informed consent will be obtained from all participants after explanation of study procedures, potential risks, and expected benefits. Eligible patients will be randomly allocated into two equal groups using a computer-generated randomization program: Group 1 (Sticky Bone group) and Group 2 (Xenograft group). Statistical Analysis: Sample size calculation was performed using G\*Power software version 3.1.9.7. The statistical test family selected was the t-test. Based on data from a previous study, a total of 16 participants were required to achieve a study power of 80% with a significance level (alpha) of 0.05. To compensate for potential dropouts, the total sample size was increased to 18 participants (9 patients per group).

Magnetic Mallet Vs Conventional Drilling in D4 Posterior Maxilla

The goal of this clinical trial is to evaluate whether the magnetic mallet technique improves primary implant stability and clinical outcomes compared with conventional drilling during dental implant placement in the posterior maxilla with soft bone quality. The main questions it aims to answer are: Does the magnetic mallet technique result in higher primary implant stability compared with conventional drilling? Does the magnetic mallet technique reduce surgical trauma and related complications compared with conventional drilling? Researchers will compare the magnetic mallet technique with conventional drilling to determine differences in implant stability, bone response, and clinical outcomes. Participants will: Undergo dental implant placement using either the magnetic mallet technique or conventional drilling. Be clinically and radiographically evaluated for implant stability and postoperative outcomes during follow-up

Clinical and Patient-reported Outcomes of Guided Versus Freehand Harvesting Of Positioning of Autogenous Bone Shells

When people lose teeth or have gum disease, the jawbone can shrink over time. This shrinkage makes it difficult for dentists to place dental implants because implants need a strong and stable base of bone. To solve this problem, surgeons often use bone grafting techniques. One of the most reliable ways to rebuild lost bone is called the autogenous shell technique. In this method, very thin plates of bone are taken from another part of the patient's mouth, shaped into a "shell," and fixed into place at the site where bone is missing. The empty space inside the shell is then filled with tiny bone chips, and the whole graft heals into strong new bone over time. Once healed, implants can be placed securely. This technique has been widely studied and is considered highly effective. However, it is not easy to perform. Traditionally, the shells are harvested and positioned by hand, relying heavily on the skill and experience of the surgeon. Even very experienced clinicians face challenges: the shells can break if cut too thin, positioning may take a long time, and results can vary from patient to patient. Patients also report significant discomfort after surgery, including swelling, pain, and difficulty eating and speaking during recovery. In recent years, digital technology has begun to transform oral surgery. Using 3D imaging and computer design, it is now possible to create custom surgical guides and positioning jigs. These guides are printed with 3D printers and act like templates, helping surgeons cut bone in exactly the right size and shape, and place it precisely in the planned position. In implant dentistry, such guides are already used for the accurate placement of dental implants, and studies show they can make surgery faster and safer. However, little is known about whether these guides also improve patient comfort and recovery when used in bone grafting procedures such as the shell technique. This clinical trial has been designed to answer that question. It compares two groups of patients who need vertical bone augmentation before implant placement: Guided group: Patients treated with 3D-printed surgical guides for harvesting and positioning bone shells. Freehand group: Patients treated with the conventional freehand shell technique without guides. By studying both groups, the trial aims to determine whether guided surgery reduces pain, swelling, and recovery problems, and whether it saves time in the operating room. Most importantly, it seeks to put patients' voices at the center by focusing on patient-reported outcome measures (PROMs)-direct feedback from patients about how they feel after the procedure.

Evaluation of Sinus Augmentation Bone Healing Using Autograft and Xenograft Compared to Xenograft Alone

To evaluate bone healing at 4 months after lateral sinus augmentation with a 4:1 ratio of autologous bone and xenograft or xenograft alone. A radiographic volumetric, histomorphometric, and histologic analysis.

Chart Review: Comparing the Position and Tilt of Dental Implants Versus Those of Natural Teeth

Background: When placing a dental implant, it is not always possible to place it exactly in the same position as the tooth that it replaced. That might be because of how the gums and mouth are shaped, since some bone is always lost after a tooth is extracted. Researchers want to study the records of people who have had dental implants. They want to check to see how much difference there is between how the implant is positioned and how the same tooth on the other side is positioned. They also want to compare how the implant is positioned compared to the tooth it replaced, when that is possible in the dental record. Study design: This study will not enroll any participants. The researchers will search the database of patient records at the study clinic to find people who have had dental implants of a single molar tooth. Then they will look at them to find records that include good images that they can use to compare the implant and tooth positions. Researchers will then analyze the findings and write a review article.

The General Aim is to Implement Clinical Assessment of Overload by Voluntary Bite Force Registration to Enable Future Simple But Precise Risk Assessment to Provide Individualized Treatment Plans.

The general aim of this clinical trial is to implement clinical assessment of overload by bite force registration to enable future simple but precise risk assessment to provide individualized treatment plans. The main questions it aims to answer are: * Can we risk-assess patients regarding overload based on bite force measurement before dental implant treatment? * Can we profile patients based on bite force to tailor precise dental implant treatment for individual patients? * Will this profiling lead to improved prognosis by reduced number of technical and/or biological complications? Participants with dental implant prostheses get their bite force measured and followed every year up to 10 years to see complications.

Assessing Current Clinical Concepts in Dental Practice

This purpose of this database is to collect, store and use appropriately derived data from routine patient care in a specialist dental practice. Comprehensive observational data will be gathered, systematically organised and be continuously updated. This data will be used to evaluate treatment outcomes and identify areas for improvement. This will contribute to the existing evidence base to validate new and current clinical concepts in dentistry. Patient consent will be sought for this, and all data extracted from patient notes will be stored and used anonymously. Use of the Oral Health Impact Profile (OHIP) -14 questionnaire pre and post treatment will be used to assess patient satisfaction with outcomes.

Compare the Difference in Occlusal Force Distribution and Denture Retention Using 2 Different Denture Base Materials in Implant Retained Overdenture

The global increase in the aging population has led to a rise in total edentulism, which remains a major public health concern. two-implant-retained mandibular overdentures have been regarded as the standard of care, offering superior retention, stability, comfort, and masticatory efficiency compared to conventional dentures. Among available attachment systems-bar, ball, stud, and magnet-the Equator attachment has gained popularity due to its low vertical profile, suitability for limited inter-occlusal space, and ease of handling. Assessment of masticatory performance and occlusal balance can be objectively measured using devices such as bite force analyzers and the computerized T-Scan system, which quantifies occlusion and disocclusion times. Conventional heat-cured polymethyl methacrylate (PMMA) remains the most widely used denture base material; however, it has mechanical and biological limitations. Flexible denture base materials have been introduced to overcome these drawbacks by enhancing adaptation, distributing occlusal loads more evenly, and improving comfort and retention.

Influence of Timing of Implant Placement on Early Healing Molecular Events

Dental implants have been on the market for several years and they are routinely used to replace single/multiple missing teeth with a high success rate. However, there is still a limited number of studies comparing the influence of timing of implant placement on wound healing. In addition, there is no data available on the signaling pathways and the expression of healing biomarkers involved in the early stages of osseointegration after immediate implant placement (IP) or delayed implant placement (DP). The primary objective of this study is to describe changes in the expression of inflammatory, angiogenesis and osseous biomarkers of saliva at 1, 3, 7, 15 and 30 days and of PICF at 3, 7, 15 and 30 days after immediate implant placement (IP) compared with delayed placement (DP).

Closed Sinus Augmentation With a Calcium Phosphosilicate Putty

The goal of this clinical study is to learn if cone beam computed tomography (CBCT) or 3-dimensional x-ray can help to let the investigator know if dental implant placement can be done after performing closed sinus surgery. The study will look at the structure of your gum where the implant will be placed after performing the surgery using 3-D x-ray and compare that to how the structure of your gum looks 6 months later. The 3-D imaging will happen after standard of care surgery to prepare your gum for an implant and then 6 months later to verify that the site is ready for the implant.

Soft Tissue Volume Changes After Immediate Implants With Two Different Techniques

The aim is to comparatively evaluate the soft tissue volume changes that occur after tooth extraction and immediate dental implant placement using two different surgical techniques. These techniques are: the Socket-Shield technique and conventional immediate placement. The null hypothesis is that the Socket-Shield technique better maintains soft tissue volume after partial tooth extraction and immediate implant placement compared to the conventional technique. From a sample of 20 patients, they will be divided into groups of 10 and will be randomized using the random.org program. The soft tissue volume will be digitally recorded by intraoral scanning before tooth extraction and 6 months later. The soft tissue dimensional changes produced will be digitally evaluated and statistically analyzed.
