The success of implant-based treatment is dependent on the correct restorative position of dental implants in the oral cavity. Often, the final prostheses require dental implants to be placed at sites with inadequate native hard and soft tissue. Bone augmentation procedures and materials have been extensively studied in the literature and various techniques have been developed over time to obtain adequate hard tissue at proposed implant sites. In the recent past, few publications have also studied soft tissue development at planned implant sites...

Background: Due to the known disadvantages of autologous bone grafting, tissue engineering approaches have become an attractive method for ridge augmentation in dentistry. To the best of our knowledge, this is the first study conducted to evaluate the potential therapeutic capacity of PRP-assisted hADSCs seeded on HA/TCP granules on regenerative healing response of canine alveolar surgical bone defects. This could offer a great advantage to alternative approaches of bone tissue healing-induced therapies at clinically chair-side procedures...

Guided bone regeneration (GBR) is a well-established and generally predictable method for repairing alveolar ridge defects and preparing edentulous sites for implant placement. Standard GBR involves filling the space underneath a membrane with autogenous bone or a mixture composed of autogenous bone particles and allogeneic bone tissue or heterologous biomaterials. The use of a barrier membrane for GBR has sometimes been associated with complications, however - reportedly involving exposure, infection, and collapse - and the non-resorbable types of membrane seem to be involved more often than the resorbable solutions...

Aesthetic implant restoration in the anterior maxilla is a challenge for clinicians. Alveolar ridge and surrounding gingiva deficiencies aggravates implant placement in the aesthetic area. This case report describes a technique for aesthetic single implant placement with simultaneous bone grafting and soft tissue thickening. At the time of implant surgery, allogenic (Maxgraft, Botiss Biomaterials, Germany) and xenogenic bone substitute (Cerabone, Botiss Biomaterials, Germany) was used for bone grafting, soft tissues were augmented simultaneously with collagen tissue matrix derivate membrane (Mucoderm, Botiss Biomaterials, Germany)...

OBJECTIVES: Tooth loss results in an inevitable alveolar ridge reduction. This has established a cautionary approach to extract, wait, augment, and insert the implant, in lieu of immediate placement. However, saving the tooth or part of it whenever possible is more conservative and supports the vital periodontal tissue buccofacial to an implant. The purpose of this cases series was to report on implant survival using this technique in a large cohort of patients at mid-term follow-up. MATERIALS AND METHODS: A private practice patient database was searched for all patients having received socket-shield treatment in conjunction with immediate implant placement...

Alveolar ridge augmentation can be completed with various types of bone augmentation materials (autogenous, allograft, xenograft & alloplast). Currently autogenous bone is labelled as the "gold standard" due to faster healing times and integration between native and foreign bone. No systematic review has currently determined whether there is a difference of implant success between various bone augmentation materials. The purpose of this paper was to systematically review comparative human studies of vertical and horizontal alveolar ridge augmentation comparing different types of bone graft materials (autogenous, allograft, xenograft & alloplast)...
