This randomized controlled clinical trial aimed to evaluate the clinical, radiographic, and histological outcomes of immediate implant loading in extraction sockets preserved using autogenous mineralized dentin graft (AMDG), beta-tricalcium phosphate (β-TCP), or no grafting. Twenty-two patients requiring extraction of maxillary premolars were enrolled, contributing a total of 27 extraction sites. Sites were randomly allocated into three groups: AMDG, β-TCP, or ungrafted control. Following socket preservation, dental implants were placed after a 6-month healing period and immediately loaded within 48 hours. Alveolar ridge dimensional changes were assessed using cone-beam computed tomography (CBCT) between implant placement and 2 years post-loading. Implant stability, peri-implant soft tissue health, and probing depths were evaluated at loading and during follow-up visits. Histological evaluation of regenerated bone was performed at the time of implant placement. The study sought to determine whether AMDG provides comparable or superior outcomes to β-TCP and ungrafted sockets in supporting immediate implant loading.
