Changes in alveolar bone following teeth extraction can compromise implant placement. Socket preservation (alveolar ridge preservation) is considered as a surgical procedure employed to preserve the ridge volume within the envelope existing at the time of extraction.The ultimate aim of such procedure is to compensate the expected amount of horizontal and vertical alveolar bone resorption. In order to better understand which socket preservation materials might be more effective for ridge preservation and to strengthen the evidence that is relevant to the clinicians' choice of socket preservation materials, two different materials were compared in a randomized controlled approach. (1) Demineralized Bone Matrix (DBM) Putty and Putty with Chips allograft covered by collagen membrane, and (2) Deprotonated bovine bone xenograft covered by collagen membrane. The independent variable is the grafting material while the dependent variables are the change in socket height, and width; the ability of implant placement without the need for grafting and the success rate of implants at the time of loading.

Inclusion Criteria:

1. Adult patient > 18 years old.
2. Single and or multi-rooted teeth that are non-restorable.
3. Patients are keen to have implant placement at the extraction sites after 4 months of extraction.
4. Intact buccal bone after extraction, which was confirmed by visual inspection and clinical examination using a periodontal probe.
5. Patients are medically fit with no underlying systemic diseases.

Exclusion Criteria:

1. Pregnant females.
2. Smokers.
3. Presence of any acute infection at the time of teeth extraction.
