Brief Summary

Periodontal diseases are one of the most prevalent chronic diseases involving a spectrum of inflammatory conditions. Intrabony defects, also known "vertical defects," are specific osseous and morphological defects and one of the consequences and end result of periodontitis. Intrabony defects are particularly associated with periodontal progression however certain patient-related factors play important role in its management such as plaque management, smoking, medical history, tooth mobility and endodontic condition. Periodontal repair is aimed to gain periodontal attachment using various modalities in severely compromised teeth, decrease pocket depth, and stabilize gingival recession. Different types of biomaterial substitutes and bone graft materials are available, but the choice of suitable "golden" type or technique is difficult and dependent on various factors particularly anatomical variations, cost effective, clinical situations, the systemic general condition, operation site, socioeconomic conditions and the surgeon choice. The current therapeutic options mainly focus on minimize symptoms and prevent disease progression but are not able to fully restore damaged bone and periodontal supporting tissues. Many of these regenerative approaches, (e.g. bone grafts) provided variable and unpredictable clinical outcomes. Therefore, it is imperative to develop alternative regenerative strategies. There is necessity to introduce novel and alternative materials of natural and synthetic origins for bone grafting use in dental field. This requires well performed clinical trials on humans to understand the effects of such materials (e.g the marine algae-based substitutes and biodegradable (absorbable) materials) either as a single or combined formula. The aim of the current clinical study is to evaluate the clinical efficacy of an algae-based biphasic bone graft material (AlgOss 20/80) and collagen membrane in the treatment of patient with intrabony periodontal defects.

Outcome Measures

Primary Outcomes (1)

  • Clinical attachment level (CAL)

    The CAL will be measured from the cementoenamel junction (CEJ) to the base of the sulcus or pocket

    From date of enrolment until the date of first documented progression i.e.at least12 months after the last enrolment.

Secondary Outcomes (1)

  • Probing pocket depth (PPD)

    From date of enrolment until the date of first documented progression i.e.at least12 months after the last enrolment.

Other Outcomes (5)

  • Bleeding on probing (BOP)

    From date of enrolment until the date of first documented progression i.e.at least12 months after the last enrolment.

  • Plaque index (PI)

    From date of enrolment until the date of first documented progression i.e.at least12 months after the last enrolment.

  • Gingival recession (GR)

    From date of enrolment until the date of first documented progression i.e.at least12 months after the last enrolment.

  • +2 more other outcomes

Study Arms (2)

Intervention

EXPERIMENTAL

Conventional flap with algae-based substitute (AlgOss) combined with collagen membrane

Combination Product: Conventional flap with algae-based substitute (AlgOss) combined with collagen membrane.

Control group

NO INTERVENTION

Conventional flap with collagen membrane

Interventions

The graft material will be prepared following the manufacturer instruction, transferred into a sterile cup than the mixture is condensed without overfilling in the intrabony defect to the level of the surrounding bony walls. The filled site will be than covered with collagen membrane.
