Study Comparing Soft Tissue Changes Using PEEK Anatomic Healing Abutments Versus Standard Titanium Healing Abutments for Single Missing Back Tooth Implant Restorations

What this Trial Is About

This clinical trial investigates the effects of implant crowns made with either a standard scan body or a polyetheretherketone PEEK anatomic healing abutment AHA in patients needing a single posterior tooth implant. The study focuses on how well these two methods preserve soft tissue around the implant and aims to improve the accuracy and comfort of dental implant restorations. It also evaluates patient outcomes related to these two different digital impression workflows. Participants will receive one of two treatments a monolithic zirconia screw-retained crown made using a standard titanium healing abutment with a standard scan body, or a similar crown made using the PEEK anatomic healing abutment digital workflow. The PEEK abutment allows for digital impressions without removing the healing abutment, potentially reducing soft tissue collapse and chairside time. Each participant is randomly assigned to one of these two groups to compare the outcomes. Throughout the study, participants will have their peri-implant soft tissue changes measured using volumetric analysis over 12 months. Researchers will assess tissue stability before and after crown delivery, esthetic scores, keratinized mucosa width, papilla height variation, and patient-related outcomes. The study includes regular evaluations to monitor these factors and ensure safety, with total participation lasting at least 12 months to observe both immediate and longer-term effects.
