Efficacy of Collagen Sponge Versus Collagen Membrane in Combination With Collagenated Bovine Bone Mineral on Ridge Preservation of Compromised Extraction Sockets in Periodontitis Patients: a Randomized Controlled Clinical Trial

Sponsor

The Dental Hospital of Zhejiang University School of Medicine

Enrollment

36 participants

Start Date

Apr 30, 2022

Study Type

INTERVENTIONAL

Conditions

Periodontitis

Summary

The study aims to evaluate the efficacy of ridge preservation with collagen sponge or collagen membrane in combination with collagenated bovine bone mineral in extraction sockets of periodontally diseased teeth.

Eligibility

Min Age: 18 YearsMax Age: 70 Years

Inclusion Criteria5

Age ≥ 18 years
Need for molar extraction due to periodontal disease and plan for late implantation
No acute infection, such as abscess or effusion
Presence of bone defects on at one or two socket walls, where the height of the horizontal (suprabony) component of the defect (alveolar bone crest - cement-enamel junction) is >50% of the corresponding root length and the bone height of socket walls is at least 3 mm
Presence of one adjacent tooth to the extraction site

Exclusion Criteria8

Smoking
Pregnancy or lactation
Untreated periodontal disease
Severe systemic conditions that contraindicate surgery (such as diabetes, heart disease, cancer etc.)
Under radiotherapy
Systemic disease or medication that influences bone metabolism and mucosal healing (such as immunosuppressants, phenytoin, bisphosphonates etc.)
Extraction of multiple adjacent teeth
Allergy to any of the materials used in the study

Interventions

PROCEDUREalveolar ridge preservation

Alveolar ridge preservation and augmentation commonly are performed immediately after tooth extraction to preserve or increase ridge volume within or beyond the skeletal envelope that exists at the time of extraction.
