Brief Summary
The objective of this clinical trial is to evaluate the impact of different torque values applied during transmucosal abutment placement in dental implants on marginal bone loss and peri-implant parameters, including the patient's perception of the treatment. The main questions the study aims to answer are: 1. Is there any difference in marginal bone loss between abutments torqued at 15 Ncm, 30 Ncm, and submerged implants without immediate transmucosal connection? 2. Are there differences in microleakage between the different torque levels? 3. How do these torque values affect peri-implant soft tissues and patient satisfaction? 4. Does the applied torque influence the patient's quality of life after the prosthetic phase? Each participant will receive three dental implants during the same surgical procedure. One of the following approaches will be applied to each implant: 1. A transmucosal abutment torqued to 15 Ncm 2. A transmucosal abutment torqued to 30 Ncm 3. A healing cap without transmucosal connection (submerged implant) After implant placement, clinical and radiographic assessments will be performed to measure marginal bone loss and peri-implant parameters.
Eligibility Criteria
Inclusion Criteria: * Posterior edentulism * Completion of craniofacial growth * Full-mouth plaque index and bleeding index \< 25% * Sufficient bone height and width for implant placement without the need for bone regeneration procedures * Presence of at least 2 mm of keratinized mucosa around the dental implant * Stable occlusion and healthy periodontium * Absence of medical conditions that contraindicate implant surgery, such as heavy smoking (\<10 cigarettes per day), severe bruxism, pregnancy or breastfeeding, bisphosphonate therapy, and patients undergoing chemotherapy or radiotherapy in the head and/or neck area * Uncooperative patients Exclusion Criteria: * Loss to follow-up * Incorrectly parallelized periapical radiographs
