Assessment of the Impact of Neocement Inject P® (Beta-Tricalcium Phosphate) on Bone Volume in Alveolar Ridge Preservation After Tooth Extraction. (BTCPARPBV)

June 5, 2026 updated by: Egas Moniz - Cooperativa de Ensino Superior, CRL

Assessment of Safety and Performance of Neobone®: A Prospective Observational Study in the Field of Dentistry

The goal of this randomized clinical trial is to assess whether β-TCP improves alveolar ridge preservation in patients who need tooth extraction. The main question it aims to answer is whether using β-TCP for alveolar ridge preservation has a positive effect on bone volume compared with natural healing.

The main questions it aims to answer are:

Does β-TCP improve ridge preservation compared with natural healing?

Researchers will compare β-TCP grafted sockets to natural healing sockets to see if β-TCP better preserves ridge volume.

Participants will:

Have a tooth indicated for extraction.

Be assigned to either β-TCP or natural healing.

Undergo CBCT and intra-oral scanning after extraction and after six months of healing to measure horizontal and vertical resorption and bone density.
