Comparative Clinical Study of Conventional vs Customized Healing Abutments in Dental Implantology

"All participants will receive a single bone-level dental implant placed in a healed posterior site of the maxilla or mandible. The implants will be placed using a biological drilling protocol and inserted with a final torque of at least 30 Ncm. A 2 mm transmucosal one-piece abutment (mono-block) will be connected at the time of surgery, following a one abutment-one time philosophy.~Each patient will receive a healing abutment immediately after implant placement according to their allocated study group (standard, wide, or customized). The assigned healing abutment will not be removed throughout the healing period. All procedures will be carried out under local anesthesia in a standard clinical setting."
