Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Collagen Membrane
ridge preservation with collagen membrane + collagenated bovine bone mineral
alveolar 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.
Collagen Sponge
ridge preservation with collagen sponge + collagenated bovine bone mineral

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Need for molar extraction due to periodontal disease and plan for late implantation
3. No acute infection, such as abscess or effusion
4. 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
5. Presence of one adjacent tooth to the extraction site
Exclusion Criteria
2. Pregnancy or lactation
3. Untreated periodontal disease
4. Severe systemic conditions that contraindicate surgery (such as diabetes, heart disease, cancer etc.)
5. Under radiotherapy
6. Systemic disease or medication that influences bone metabolism and mucosal healing (such as immunosuppressants, phenytoin, bisphosphonates etc.)
7. Extraction of multiple adjacent teeth
8. Allergy to any of the materials used in the study
