Peri-Implant Tissues

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.

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).

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
