NCT07433920
the rationale of the current study is to address a focused and clinically relevant gap in socket shield therapy: which biologic modality best supports healing of the shield-implant gap when SST is performed under a standardized, digitally guided workflow. The study will compare three shield-implant gap filling modalities: (i) L-PRF alone (without membrane), (ii) sticky tooth (autogenous dentin graft +i- PRF), and (iii) sticky bone (particulate graft + i- PRF) under AI-assisted, patient-specific guided implant placement based on IOS/CBCT superimposition, with CBCT follow-up at immediate, 3 months, and 6 months. The working hypothesis is that biologically active, cohesive composites (sticky tooth and sticky bone) will provide superior hard- and soft-tissue dimensional stability compared with PRF alone by improving space maintenance and early wound stability in the shield-implant gap . The null hypothesis is that there will be no statistically significant differences between the three modalities in radiographic and digitally assessed clinical outcomes over the 6-month follow-up period .

NCT07333534
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?

Modified socket shield therapy (SST) has been proposed to preserve the facial plate and peri implant tissues. Whether spontaneous healing after two stage modified SST provides outcomes comparable to grafted SST before delayed implant placement remains unclear.
NCT07456995
This clinical trial evaluates how different surface treatments on a metal base (Ti-Base) affect the success of dental crowns on implants. Patients receiving a zirconia crown for a missing lower back tooth are divided into three groups: one group receives no special treatment on the metal base, one group receives a silica coating, and the third receives both a silica coating and a chemical primer. The study monitors these crowns for one year to see which treatment best prevents the crown from coming loose or breaking, while also checking the health of the surrounding gums.
NCT07459036
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.

H0: "Within the first year post-placement, four interforaminally placed, immediately loaded 2.4 mm narrow-diameter one-piece TiZr implants with miniaturized stud-type attachments show improved patient-reported outcome measures (PROMS) compared to two interforaminally placed, early loaded, TiZr two-piece implants with stud-type attachments to retain a mandibular overdenture."The specific aim is to compare both treatment alternatives to evaluate which one may be recommended for elderly edentulous patients.
NCT06647381
The population of interest will be recruited out of a cohort of patients who were initially treated at the Department of Oral Surgery and Stomatology between 1997 and 2001. The findings from a total of 56 patients that received tooth replacement treatment with dental implants during this period, were previously published in 2008. Now, 20 years later, the investigators will potentially recruit and re-examine as many patients as possible out of this original cohort. Exclusion criteria will be patients not able to come to the re-examination, concomitant diseases that compromise the health of this subject during the comprehensive examination (i.e., active severe infectious diseases, liver or kidney dysfunction/failure, currently under treatment), pregnant women, or unwilling to sign the consent form. Besides them, no further exclusion criteria are defined as patients receiving no intervention. The investigators assume that will be able to retrieve 40 patients having roughly 80 implants with sinus floor augmentation. Recruitment, screening, and informed consent procedure Patients treated at the Department of Oral Surgery between 1997 and 2001 and who were included in the previous case series study will be potentially recruited. Patients who are willing to participate will receive informed consent. The risks and benefits of being part of this study will be thoroughly explained to the patients without a limit of time. All the questions will be answered. After signing the informed consent patients will be examined. The participants will not be charged any costs for the recall examination. Study procedures After ethical approval, available patients will be screened and recruited for a re-examination visit. The anamnesis of the patients will be assessed using a questionnaire. In case of uncertainties regarding the medical history, a report from the patient's physician will be requested. During this re-examination, photographs, in combination with a comprehensive and standard clinical and digital examination will be taken. Further, patients will be given questionnaires to assess patient-reported outcomes. The evaluation visit will take place within a maximum of 1 hour, as the normal time required for a recall appointment on this type of patient with the presence of dental implants. Besides this one re-examination, no more visits will be necessary for the study outcomes. Data will be encrypted and collected in Redcap Software. The key for the encryption will be set up and stored by a person who is not involved in the study.
NCT06527950
Immediate implant placement has been proven to be a successful treatment modality, it is however considered a technique sensitive procedure, which mandates careful planning on basis of the recommended guidelines and thorough site assessment. The anatomical characteristics play a major role in the treatment planning, to determine that enough alveolar bone housing is available to accommodate the implant in the correct prosthetic-driven position and to avoid complications that may be caused by injury of the adjacent anatomical structures. There is scarcity in the literature regarding data on the anatomical features of the mandibular anterior zone in relevance to immediate implant planning. Analysis of the anatomical landmarks of the mandibular anterior region to determine the thickness of the labial and lingual alveolar bony plates, in addition to the bony socket configuration along with the labio-lingual socket dimension and relate them to immediate implant treatment planning

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.
NCT07310979
This prospective clinical study aims to evaluate the clinical and radiographic outcomes of a novel triple-abutment system with hyperbolic paraboloid geometry installed on Morse taper dental implants. The system is designed to support three adjacent crowns on a single implant, aiming to optimize load distribution and preserve peri-implant tissue stability. Thirty systemically healthy adults missing three adjacent teeth will undergo implant placement, followed by a healing period of approximately three months for osseointegration prior to prosthetic loading. Metal-ceramic restorations will then be cemented over triple abutments. Clinical and radiographic evaluations will be performed at T1 (3-4 months after prosthetic loading) and T2 (12-18 months after prosthetic loading). The primary outcome will be marginal bone level change assessed by standardized periapical radiographs. Secondary outcomes include probing depth, bleeding on probing, plaque index, keratinized mucosa height, and patient-reported satisfaction. The study aims to investigate whether this innovative abutment design provides stable peri-implant conditions and favorable clinical performance when applied to Morse taper implants.
