Extraction Socket Augmentation. A Clinical Study
Extraction Socket Augmentation Using GTO vs. Apatos. A Randomized Controlled Clinical Study

Conditions
Summary
Extraction socket preservation is defined as alveolar ridge preservation within the bone envelope remaining after tooth extraction, meanwhile ridge augmentation is defined as increasing the volume of alveolar ridge beyond the bony envelope at the time of tooth extraction. It is recommended to use in cases where extraction socket anatomy is intact. In contrast definition "extraction socket augmentation" defines alveolar ridge restoration when bony walls of the socket are partly or completely lost. In the case of severe loss (\> 50%) of the buccal bone plate, preservation of hard tissue with a prolonged healing time before implant placement has been suggested. The null hypothesis of this experimental work states that: (i) the two different bone graft materials gained the same amount of bone following horizontal ridge augmentation procedure; (i) the two different bone graft materials exhibit similar histological and histomorphometric results Therefore, the main purpose of the current study is to compare two different biomaterials using guided bone regeneration procedures in the ridge preservation/ augmentation (hard-tissue preservation).
Eligibility
Inclusion Criteria10
- Age: ≥ 18 years.
- Good general health.
- Single-tooth implant treatment. Presence of adjacent teeth and opposing occluding teeth (for measurement stent indexing).
- Incisors, canines and premolars.
- Presence of three intact socket walls after tooth extraction with a defect of more than 50% loss of the buccal ridge wall and no fragment of root should be left.
- Reasons for tooth extraction: carious lesion, endodontic complication, root fracture and prosthetic reason.
- Good oral and periodontal health.
- Full-mouth plaque and bleeding < 20%.
- Able and willing to follow study procedures and instructions.
- Informed consent.
Exclusion Criteria12

Existence of any systemic condition such as uncontrolled diabetes mellitus, cancer, HIV, disorders that compromise wound healing, chronic high dose steroid therapy, intravenous and oral bisphosphonate therapy, bone metabolic diseases, history of irradiation of the head and neck area, or any other immunosuppressive therapy that would contraindicate oral surgical treatment.

Interventions
After teeth extraction, a guided bone regeneration procedure will be performed using a bone graft and a soft collagenated cortical membrane as graft stabilizer. Implant placement surgery will also be performed.
