Evaluation of a Novel Horizontal Ridge Augmentation Technique in Dentistry

Bone Loss, Alveolar Clinical Trial

Official title: Histological and Raman Spectroscopy Evaluation of Edentulous Alveolar Ridge Horizontal Bone Augmentations Using a Xenogeneic Bone Substitute and Autologous Platelet Concentrates: A Prospective Case Series

Status Completed

Clinical Trial Summary

This case series aimed to assess the efficacy of a novel horizontal ridge augmentation modality using histomorphometry and Raman spectroscopy. Combinations of "sticky bone" and tenting screws without autologous bone were used as augmentative materials.

Clinical Trial Description

This case series aimed to evaluate the efficacy of the horizontal augmentation technique using the tenting screw technique with "sticky bone." The main aim was to determine whether this method provides similar results to the gold standard GBR or autologous onlay block grafts. In addition, the validity of neglecting autologous graft and its possible substitution with growth factor concentrate were examined. The novelty of this study is that no human histological examination of the described procedure has been conducted previously. It is hypothesized that the "stick bone" containing autologous platelet concentrate can substitute the use of particulate autologous bone graft in these type of procedures. In this prospective case series study five patients were enrolled and treated with the same type of bone augmentation in order to increase the alveolar ridge in the horizontal dimension with the previously mentioned technique. After 5 months of healing a second reentry surgery was performed in order to harvest the bone core for biopsy, to asses the chemical compound composition by Raman spectroscopy in vivo and to place the dental implants at the same time. Newly formed tissues were evaluated clinically during reentry, radiologically by CBCT acquisition, qualitatively and quantitatively by histological processing and physicochemically by means of Raman spectroscopy. ;
