Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In addition to alveolar ridge resorption in a horizontal dimension (decrease in width), changes in the vertical dimension of the ridge have been documented following tooth extraction in a canine model. The healing pattern of the extraction socket observed in the preclinical setting was further confirmed in human investigations). A systematic review concluded that greater loss of ridge width is to be expected following extraction compared to loss of ridge height. Clinical mean reductions of 3.87mm and 1.87mm in ridge width and height, respectively, were reported. Radiographically, the mean reduction amounted 1.21mm and 1.53mm for ridge width and height, respectively. These results were confirmed by another systematic review.
If the extracted tooth is to be replaced, the unfavorable dimensional changes resulting from this healing process may necessitate advanced and technique sensitive guided bone regeneration (GBR) procedures prior to dental implant placement. In order to avoid GBR and limit these dimensional changes, grafting of the extraction socket with or without membrane coverage, also called ridge preservation procedure, have been advocated. In order to perform ridge preservation, typically, a graft material and some sort of a barrier (e.g. non-resorbable and resorbable membranes or collagen wound dressing) are used. A large variety of materials are available on the market for the purpose of ridge preservation. No material gold standard has yet been identified to date, which would ensure the best dimensional stability of the alveolar ridge.
Current materials used as part of standard care in clinical practice include freeze dried bone allograft (FDBA) as a grafting material and a dense polytetrafluroethylene (dPTFE) non-resorbable membrane or a collagen wound dressing (Collaplug®, Zimmer Dental, Carlsbad, CA) to protect the extraction grafted site. It is currently now known how the use of a collagen wound dressing would compare to a non-resorbable membrane (which has been documented) and if any would lead to any substantial clinical advantages.
Therefore, the proposed research project will answer the following question:
What are the dimensional changes of the hard and soft tissues encountered following molar extractions with ridge preservation using FDBA and a collagen wound dressing?

Study Groups

Ridge preservation in molar sites
Patient who will need a single molar site extracted as part of their treatment will be screened and consented for this research study.
Ridge preservation will be performed in single molar extraction site. The site will be grafted with freezed dried bone allograft (FDBA) and covered with a collagen wound dressing (Collaplug). This is already part of clinical standard care using FDA approved products in an FDA approved fashion. The study aims at documenting the clinical outcome of such accepted procedure more precisely and compare it existing data using other materials.
Ridge preservation
Ridge preservation consists of grafting an extraction socket with a bone substitute and /or cover it with a membrane or a dressing. This intervention is aiming at limiting the osseous dimensional changes that would have taken place if the extraction would have been left to heal spontaneously.
FDBA
Ridge preservation consists of grafting an extraction socket with a bone substitute and /or cover it with a membrane or a dressing. This intervention is aiming at limiting the osseous dimensional changes that would have taken place if the extraction would have been left to heal spontaneously. In this study a freezed dried bone allograft (FDBA) will be used and the site will be covered with a collagen wound dressing (Collaplug)
Collagen wound dressing
Ridge preservation consists of grafting an extraction socket with a bone substitute and /or cover it with a membrane or a dressing. This intervention is aiming at limiting the osseous dimensional changes that would have taken place if the extraction would have been left to heal spontaneously. In this study a freezed dried bone allograft (FDBA) will be used and the site will be covered with a collagen wound dressing (Collaplug)
