Clinical Trial Summary

The aims of the study was to correlate the extent of the dimensional alveolar bone changes after tooth extraction and contextual guided bone regeneration with serum vit D levels in 14 patients. Moreover, at 4 months, a small bone sample was collected in order to correlate histological and immunohistochemical parameters of bone with vit D serum levels.

Description:

The study included 14 patients requiring tooth extraction and subsequent post-extraction bone regeneration with heterologous graft material of porcine origin. Four months after extraction, dental implants were placed, and insertion torque values (ITV) and implant stability quotients (ISQ) were recorded. During implant placement, a small bone sample was collected for histological analysis. The aim of the study was to analyze the correlation between serum vitamin D levels and post-extraction bone volume contraction, collagen type I (Col1A1), osteocalcin, osteopontin, runt-related transcription factor 2 (Runx2), ITV, ISQ, Newly Formed Bone Tissue (NFBT).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dimensional alveolar bone changes	Volumetrical changes of alveolar bone after tooth extraction measured by superimposition of two intraoral scans. The first was registered before the extraction of the tooth. The second was registered after 4 months (before inserting implant). The parameter used to measure the dimensional alveolar bone change is called "Integrated Distance" and it is expressed in mm3.	From extraction to implant insertion (4 months)
Primary	Evaluation of new formed bone tissue	Evaluation of new formed bone tissue performed by histomorphometric methods.	Time of implant insertion: 4 months after extraction
Primary	Evaluation of Total Calcified Tissue (TCT)	Evaluation of Total Calcified Tissue composed by the residual bone substitute utilized for regeneration plus the NFBT. The evaluation was performed by histomorphometrics methods.	Time of implant insertion: 4 months after extraction
Primary	Expression of Collagen A1	quantitative analysis of immunohistochemistry performed using deconvolution tool for ImageJ.	Time of implant insertion: 4 months after extraction
Primary	Expression of Osteocalcin	quantitative analysis of immunohistochemistry performed using deconvolution tool for ImageJ.	Time of implant insertion: 4 months after extraction
Primary	Expression of Osteopontin	quantitative analysis of immunohistochemistry performed using deconvolution tool for ImageJ.	Time of implant insertion: 4 months after extraction
Primary	Expression of Runx-2	quantitative analysis of immunohistochemistry performed using deconvolution tool for ImageJ.	Time of implant insertion: 4 months after extraction
Primary	Evaluation of Implant Stability Quotient (ISQ)	Evaluation of Implant Stability Quotient after the implant insertion. The measurement was performed with "Osstell" system (W&H)	Time of implant insertion: 4 months after extraction
Primary	Evaluation of Implant Torque Value (ITV)	Evaluation of Implant Torque Value at the implant insertion performed with the surgery implant device.	Time of implant insertion: 4 months after extraction
