About this trial
Tooth extraction leads to a substantial reduction in alveolar bone volume, with up to 25% loss within the first year and up to 40-60% within three years. This prospective randomized clinical study aims to compare four commonly used methods of alveolar ridge preservation, evaluating their effectiveness in maintaining bone volume for later prosthetic or implant rehabilitation. Alveolar dimensions will be measured using calibrated CBCT imaging pre-extraction and at six months post-extraction.

Treatments tested in this trial
Tooth extraction left to heal spontaneously
Procedure/SurgeryWound after the tooth extraction will be secured with a stitch without addition of any augmentation material.
Tooth extraction plus collagen sponge
Procedure/SurgeryWound after the tooth extraction will be filled with a collagen sponge (Parasorb Cone, Resorba, Germany) and secured with a stitch.
Tooth extraction plus tricalcium phosphate
Procedure/SurgeryWound after the tooth extraction will be filled with tricalcium phosphate xenograft (Poresorb TCP, Lasak, Czech Republic), covered with a collagen sponge (Parasorb Cone, Resorba, Germany), and secured with a stitch.
Tooth extraction plus autogenous dentin
Procedure/SurgeryWound after the tooth extraction will be filled with grounded autogenous dentin, covered with a collagen sponge (Parasorb Cone, Resorba, Germany), and secured with a stitch.
