Flapless Mini-incision Implant Surgery

evaluate the clinical efficacy of the flapless mini-incision method compared to conventional flap and flapless punch methods

Comparison Between Socket Shield and Conventional Techniques in Immediate Implant Placement.

The goal of this randomized clinical trial is to compare whether immediate implant placement using the socket-shield technique can better preserve bone density, bone level, and peri-implant tissue health compared to conventional immediate implant placement in patients requiring tooth extraction in the maxillary esthetic zone. This study is conducted in systemically healthy adult patients aged 20-60 years who have non-restorable maxillary anterior teeth indicated for immediate implant placement. The main questions this study aims to answer are: Does the socket-shield technique result in better peri-implant bone density and bone level preservation compared to the conventional immediate implant technique? Does the socket-shield technique lead to improved clinical peri-implant parameters, including probing depth, bleeding on probing, keratinized tissue width, and soft tissue thickness? participants will be divided into two groups: (both groups will receive immediate implant placement of a tooth requiring extraction in the maxillary esthetic zone.) First group: will recieve immediate implant using conventional technique. second group: will recieve immediate implant using socket shield technique. Participants will: * Undergo clinical and radiographic examinations, including cone beam computed tomography (CBCT). * Receive immediate implant placement using either the conventional technique or the socket-shield technique. * Be followed up clinically and radiographically for 9 months to assess bone and soft tissue healing. * Attend regular postoperative and follow-up visits for evaluation of implant stability and peri-implant tissue health.

Volumetric Analysis of Peri-Implant Soft Tissue Changes Between Polyethereketone(PEEK) Anatomic Healing Abutments and Standard Healing Abutments in Posterior Single Implant Restorations

This prospective randomized clinical trial will evaluate the clinical outcomes of the implant crown fabricated with standard scan body (control) and polyetheretherketone (PEEK) anatomic healing abutment (test).

The Effect of Injectable Platelet-Rich Fibrin in Peri-implant Soft Tissue

An inadequate amount of peri-implant soft tissue results in more plaque accumulation around the implants, peri-implant mucositis, marginal bone loss, mucosal recession, and/or attachment loss. In the literature, there are studies evaluating the application of injectable platelet-rich fibrin to the gingiva and oral mucosa around teeth, but injectable platelet-rich fibrin application around implants has not been encountered. This study aimed to evaluate the effect of subgingival and submucosal application of injectable platelet-rich fibrin on peri-implant soft tissue phenotype in patients with inadequate peri-implant soft tissue phenotype.The study will include 80 systemically healthy and non-smoking patients/implants older than 18 years of age with insufficient peri-implant keratinized mucosa width and mucosal thickness who applied to Kütahya University of Health Sciences, Faculty of Dentistry, Department of Periodontology. There are two study groups according to peri-implant mucosa phenotype: Thin phenotype and thick phenotype. All patients will undergo the same procedure of injectable platelet-rich fibrin application

Prospective Longitudinal Clinical Study for the Evaluation of Peri-implant Tissue and Osseointegration After Rehabilitation With Osseointegrated Implants

The success of rehabilitation with osseointegrated implants is associated with numerous factors, including patient characteristics, installed implants, proper planning, and the prosthetic connections used. In the long term, success is closely related to the clinical radiographic follow-up of the implanted region and the identification of intrinsic or extrinsic factors that may interfere with implant survival. Therefore, the objective of this study is to evaluate, through clinical and radiographic analysis, the peri-implant tissues and prosthetic connections of research participants rehabilitated with osseointegrated implants at the Implant Dentistry Clinic of the Federal Fluminense University, over a period of 5 years. This will be a double-blind longitudinal study. A total of 148 research participants will be selected, respecting the inclusion criteria: completion of surgical-prosthetic planning by the Implant Dentistry Clinic team at UFF, including osseointegrated implants and prosthetic components manufactured by SIN Implant System (São Paulo, Brazil); agreeing to and signing the informed consent form, being willing to be monitored for a period of 5 years; systemically healthy patients who do not use antiresorptive and antiangiogenic drugs; patients with a plaque index \<20% (Ainamo \& Bay 1975) and bleeding on probing \<20% (Muhlemann \& Son 1971) at the start of the study. Participants will undergo clinical and radiographic analysis of peri-implant tissues and prosthetic connections at the following intervals: up to 7 days after implant installation (Time 0), at the time of prosthesis installation (Time 1), 6 months after prosthesis installation (Time 2), and 1 to 5 years after prosthesis installation (Times 3, 4, 5, 6, and 7, respectively). It is expected that this longitudinal study will lead to a better understanding of the factors influencing peri-implant bone loss and long-term success.
