Socket Preservation Using Autogenous Dentin (SPAD)
20. maj 2026 opdateret af: University of Ostrava
Socket Preservation After Tooth Extraction Using Autogenous Dentin in Comparison With Other Techniques
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.

Detaljeret beskrivelse
The study evaluates four different approaches to alveolar ridge preservation after tooth extraction.
Eligible patients aged 18-70 years will undergo minimally traumatic extraction.
Four treatment modalities will be compared: 1) Spontaneous healing secured with a stitch (control group), 2) Application of collagen sponge (Parasorb Cone, Resorba, Germany) secured with a stitch, 3) Application of a tricalcium phosphate xenograft (Poresorb TCP, Lasak, Czech Republic) covered with a collagen sponge (Parasorb Cone) and secured with a stitch.
4) Application of autogenous dentin, covered with a collagen sponge (Parasorb Cone) and secured with a stitch.
Alveolar ridge dimensions will be measured on CBCT before extraction and again after six months.
Primary outcomes include the absolute and relative change in ridge width and height at 1 mm, 3 mm, and 5 mm below the highest point of the alveolar bone as per Del Canto-Díaz, 2019.
Patient factors (periodontal biotype, soft tissue phenotype, and vestibular thickness of the alveolar bone) will be recorded to allow subgroup analysis.
