Immediate Implant Placement in the Esthetic Zone With and Without Using Autogenous Mixed With Xenograft

2019-09-25 06:13:35 | BioPortfolio


Xenografts are graft materials derived from the inorganic portion of animal bones; the most common source is bovine the removal of the organic component are processed to remove their antigenicity, while the remaining inorganic components provide a natural matrix as well as an excellent source of calcium. The disadvantage of xenografts is that they are only osteoconductive and the resorption rate of bovine cortical bone is slow.

However leaving the jumping gap empty has been the gold standard for immediate implantation as the formed blood clot will allow bone fill in that area.


Not using a grafting material in the jumping gap was chosen as a comparator as it's the standard procedure usually applied and showed high success rates. This should allow us to assess whether the chosen grafting material would have a positive influence on the study outcomes as compared to it.

Intraoral and extraoral autologous bone grafts could be considered as the "Gold standard" pre-prosthetic dentoalveolar reconstruction of atrophic jaws with cortico-cancellous bone grafts from intraoral and/or extraoral donor sites as a predictable technique for the facilitation of dental rehabilitation of atrophic ridges, associated with high bone survival rate and long term implant success. Autogenous bone corresponds to bone graft obtained from the same individual. It is considered the gold standard for filling of bone defects since it allows (I) osseointegration: direct contact with bone tissue without fibrous tissue ; (II) osteoconduction: support to bone growth (III) osteoinduction: differentiation of mesenchymal cells of surrounding tissue (receptor site) into osteoblastic cells ; and (IV) osteogenesis: bone neoformation by osteoblastic cells present in the graft material. Although few mature osteoblasts survive to grafting, precursor cells are responsible for the osteogenic potential

Fixation of the ANTERIOR CRUCIATE LIGAMENT, during surgical reconstruction, by the use of a bone- patellar tendon autograft.

The complement of teeth in the jaws after the eruption of some of the permanent teeth but before all the deciduous teeth are absent. (Boucher's Clinical Dental Terminology, 4th ed)

"Decayed, missing and filled teeth," a routinely used statistical concept in dentistry.

Process of restoring damaged or decayed teeth using various restorative and non-cosmetic materials so that oral health is improved.

The selective extraction of deciduous teeth during the stage of mixed dentition in accordance with the shedding and eruption of the teeth. It is done over an extended period to allow autonomous adjustment to relieve crowding of the dental arches during the eruption of the lateral incisors, canines, and premolars, eventually involving the extraction of the first premolar teeth. (Dorland, 28th ed)
