Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single application of experimental device - TetraMax-B (TMB) or comparator control device (BioOss Collagen granules) by direct injection into the post-extraction dental socket. The approximate duration of the interventional procedure is 2 hours. All devices will be administered by an experienced dental implant surgeon and specialist periodontist. A maximum of 0.7ml of investigational product (TMB) (40% TetraMax 60% BioOss granules) will be applied. A maximum of 2.5ml of comparator control device BioOss Collagen will be applied. Total amount applied is dependent of dental socket dimensions.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The PI will determine if a subject is eligible for inclusion in the clinical investigation and if so, obtain required informed consent.
The PI will advise the sponsor that a clinical trial participant is available for inclusion in the clinical investigation.
The sponsor will randomise the clinical trial participant to the applicable treatment plan (investigational product TMB or SOC comparator BioOssCollagen) using a sealed opaque envelope concealment process.
The PI will be informed whether the participant has been assigned to a standard of care or investigational product treatment plan.
It is not possible to conceal the TMB versus comparator status from the PI for this clinical investigation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random order for the allocation of subjects will be generated using computer software.
Masking / blinding
