Dental implants are considered a predictable rehabilitative option following tooth extraction or in cases of missing teeth. In some situations, the inevitable alveolar ridge resorption that occurs after extraction may make the placement of standard-diameter (\>3.5 mm) or standard-length implants difficult or even impossible without advanced bone augmentation procedures. To counteract post-extraction volumetric bone contraction, alveolar ridge preservation can be performed, consisting of placing a bone graft within the socket walls immediately after tooth extraction. Although this procedure cannot completely prevent dimensional changes, it has been shown to significantly reduce both horizontal and vertical ridge resorption, as reported in the scientific literature. However, there is a lack of clinical and radiographic studies evaluating the outcomes of implant rehabilitation following alveolar ridge preservation with standard-dimension implants in a hospital-based setting.
Patients requiring alveolar ridge preservation procedures prior to implant rehabilitation of edentulous sites;
Age > 18;
Achievement of FMPS and FMBS ≤ 15%;
Signed written informed consent to participate in the study.
Uncontrolled diabetes or hypertension;
Uncontrolled periodontal disease;
Inability to perform consistent and continuous follow-up;
Pregnancy or breastfeeding;
Patients aged 18 years and older requiring bone regeneration with an alveolar ridge preservation technique prior to implant rehabilitation will be included in the study.

Volumetric analysis
The dimensional change of hard tissues following bone regenerative procedures will be assessed radiographically by measuring horizontal and vertical bone resorption through CBCT comparison in patients treated in a hospital-based setting.
Esthetic evaluation
Assessed using the PES/WES esthetic index. Scores range from 0 to 14 for the PES and from 0 to 10 for the WES, with higher scores indicating better esthetic outcomes.
Implant success rate
Absence of biological and technical complications, expressed as a proportion
Implant survival rate
Rate of dental implants remaining in situ, measured as a proportion
Prosthesis success rate
Absence of technical complications, expressed as a proportion
