An allograft is donated human tissue that is transplanted into another person of the same species. In dentistry, allograft most commonly refers to **donor bone graft material** used to support bone healing. It is frequently used around **extraction sites, implants, and periodontal (gum) defects**. The material is processed and supplied in forms designed for surgical handling.

An autograft is graft material taken from your own body and moved to another site. In dentistry, autograft most often refers to your own bone or gum tissue used to rebuild or thicken an area. It is commonly used around dental implants, after tooth removal, and in periodontal (gum) procedures. Because the tissue comes from the same person, it is considered “self-sourced” grafting.

A bone graft is a material placed into an area of missing or thin bone to support new bone formation. In dentistry, bone graft is commonly used in the jaw (alveolar bone) around teeth and dental implants. It can be used after tooth removal, around periodontal (gum) defects, or to rebuild ridge shape. The graft acts as a scaffold, and the body gradually remodels it into living bone to varying degrees.

titanium mesh is a thin sheet of medical-grade titanium with small openings (a “mesh” pattern). It is commonly used in dental and oral surgery to help shape and support healing bone. It often works alongside bone graft material during procedures to rebuild jawbone volume. It is also used in broader maxillofacial reconstruction when stable, lightweight support is needed.

A **nonresorbable membrane** is a barrier material placed during certain dental surgeries to separate tissues while healing occurs. It is most commonly used in **guided bone regeneration (GBR)** and **guided tissue regeneration (GTR)** procedures. Unlike resorbable membranes, it **does not break down on its own** and typically requires removal by a clinician. Its main role is to help protect a space so bone or gum-supporting tissues can regrow more predictably.

A resorbable membrane is a thin, temporary barrier used during certain dental and periodontal surgeries. It is designed to slowly break down in the body over time, so it typically does not need to be removed later. In dentistry, it is most commonly used in guided bone regeneration (GBR) and guided tissue regeneration (GTR). Its main role is to help create a protected space for bone or gum-supporting tissues to heal.

A barrier membrane is a thin material placed to separate tissues during healing or a dental procedure. In dentistry, it is commonly used to protect a wound area and help guide bone or gum healing. Some barrier membrane products are soft sheets used in surgery, while others are light-cured resins used as temporary protective “barriers” during chairside treatments. The main idea is the same: create a controlled boundary so the right tissues heal in the right place.

GBR is a tooth-colored, resin-based material used to restore or seal parts of a tooth. It is typically placed using adhesive bonding and then hardened with a curing light. In everyday terms, it is a “bonded, light-cured tooth-colored resin” used in fillings and repairs. It is commonly used in restorative dentistry, especially for small-to-moderate repairs and as a supportive layer under other materials.

guided bone regeneration is a dental surgical technique that helps rebuild jawbone where bone volume is missing. It uses a bone graft material and a barrier membrane to guide healing toward new bone formation. It is commonly used in implant dentistry, periodontics, and oral surgery when bone is too thin or low. The goal is to create a stable foundation for teeth or dental implants.

GTR is a dental term commonly used to describe **gingival tissue replacement** using tooth-colored or gum-colored restorative material. In simple terms, it means **rebuilding the look of missing or uneven gum tissue** with a bonded dental resin. GTR is most often used in **aesthetic dentistry** to manage visible “black triangles,” gum recession appearance, and cervical (near-the-gumline) defects. It may be done as a **direct chairside procedure** or as part of a broader restorative plan.
