简要总结

This study hypothesizes that the SHIELD technique, when combined with a suitable bone graft material, enables successful immediate implant placement in Type 3 extraction sockets with buccal bone dehiscence, regardless of the extent of buccal bone loss. Specifically, it is proposed that the regenerative potential of the SHIELD technique is not significantly affected by the degree of buccal bone dehiscence, whether in compromised sockets (ST3 Subclass B, when a buccal dehiscence is present and extending 1/3 to 2/3 of the total length of the alveolus) or severely compromised sockets (ST3 Subclass C, for severe dehiscence passing more than 2/3 of the facial bone of the alveolus). All in all, this study aims to assess the clinical performance of the CE-approved medical device NOVAMag® SHIELD by evaluating its success rate and long-term suitability for the rehabilitation of edentulous regions in routine clinical settings. It further seeks to generate clinically meaningful evidence supporting the safety and efficacy of magnesium-based biomaterials in the management of complex post-extraction defects. In addition, the study investigates the CE-approved self-tapping conical implant VEGA® + to obtain comprehensive clinical data contributing to post-market surveillance and continuous product evaluation.

详细描述

This prospective, controlled observational clinical study aims to evaluate the clinical and radiographic outcomes of bone regeneration using the SHIELD Technique with the NOVAMag® membrane XS (SHIELD) in 40 patients of the periodontology department requiring regenerative treatment in the aesthetic region.

Patients will be stratified into two groups of 20 individuals each, based on the condition of the extraction socket. The first group will include compromised sockets classified as ST3 Subclass B, in which a buccal dehiscence extends from one-third to two-thirds of the total length of the alveolus, while the second group will comprise severely compromised sockets classified as ST3 Subclass C, in which the dehiscence extends over two-thirds of the facial bone of the alveolus.

In both groups, cerabone plus (a bovine bone substitute mixed with hyaluronic acid) will be used as the grafting material. In all patients, the CE-approved self-tapping conical implant VEGA® + will be immediately placed, allowing the study to obtain comprehensive clinical data contributing to post-market surveillance and continuous product evaluation.

All procedures will adhere to established ethical standards, including data protection (all patient data will be anonymized prior to collection to ensure confidentiality), informed consent, and rigorous clinical follow-up, ensuring that the study provides reliable and clinically relevant evidence on the performance of magnesium-based membranes in the management of complex post-extraction defects, as well as the clinical performance of immediately placed VEGA® + implants.
