Efficacy and Safety Evaluation Study of Implants With Periodontal Ligament

The goal of this clinical trial is to evaluate the efficacy and safety of periodontal ligament-integrated implants placed via residual periodontal ligament tissue in extraction sockets in adult patients (aged 18 and older) requiring extraction of a single-rooted tooth. The main questions it aims to answer are: * Does the periodontal ligament-integrated implant achieve stable integration with the jawbone at 24 weeks after placement? * Can this implant reproduce physiological tooth mobility and sensory function similar to natural teeth while maintaining periodontal health? This is a multicenter, single-arm, exploratory study with approximately six participants. Participants will: * Undergo tooth extraction of one single-rooted tooth that meets eligibility criteria. * Receive immediate placement of a periodontal ligament-integrated implant into the extraction socket. * Attend scheduled follow-up visits over 48 weeks for assessments including: * Dental X-rays and clinical examinations to evaluate bone healing, periodontal ligament formation, and implant stability. * Measurements of tooth mobility, pocket depth, and pain levels. * Quality of life assessments using a standardized oral health questionnaire. Researchers will monitor participants for implant integration, safety outcomes, and physiological function restoration over the study period.
