“…This suggested that the graft was stable just after implant placement. Xenogenic grafts are able to integrate into the host bone, in sandwich cases promoted by two sides of vascularized recipient bone (Cordaro & Terheyden, ; Domingues et al, ; Laino et al, ; Mounir, Mounir, Abou‐Elfetouh, & Shaker, ). Bovine bone integrates with regenerated bone but is resorbed slowly (Bechara et al, ).…”

Objectives:The aim of the present retrospective study was to assess the long-term clinical outcome of sandwich osteotomy in pre-implant augmentation of atrophic mandible. Materials and methods:Sandwich osteotomies were performed in partially and fully edentulous mandibles of 63 consecutive patients in the present study. The vertical bone gain, graft stability, and marginal bone loss were measured radiographically.Implant survival and success rates were estimated in the follow-up ranged from 2 to 144 months (mean, 58 months). Results: A total of 75 procedures were reviewed. After an average healing time of 148 days, 220 implants were placed in 74 procedures. Perioperative complications included intraoperative fracture (1/75), transient paresthesia (18/75), wound healing disturbance (18/75), and keratinized tissue deficiency (14/75). The average vertical bone gain was 5.4 mm at the time of implant placement. Significant marginal bone loss occurred during the first 6 months, after which the resorption remained stable. The implant survival rate was estimated as 96.7%, and the success rate was 95.3%. Implant survival and success showed no significant correlation with higher age, anticoagulation therapy, cardiovascular disease, or thyroid disorder. Smoking was correlated with significant lower success rate. Conclusion: Sandwich osteotomy is a suitable augmentation procedure for atrophic mandible, allowing for implant placement with promising outcome.

“…The higher the surface roughness of the structure, the higher the rate at which the ions are released. Fernandes et al noted that, among these ions, Ag + is the common ion that is doped on glass and glass-ceramics studied in recent studies [ 339 ]. Hence, these materials play a crucial role at the site of dental implants as Escherichia coli, Staphylococcus aureus , S. epidermidis , and Pseudomonas aeruginosa are identified to be present in 90% of all dental implants [ 339 , 340 , 341 , 342 ].…”

Biomimetic Aspects of Oral and Dentofacial Regeneration

Biomimetic materials for hard and soft tissues have advanced in the fields of tissue engineering and regenerative medicine in dentistry. To examine these recent advances, we searched Medline (OVID) with the key terms “biomimetics”, “biomaterials”, and “biomimicry” combined with MeSH terms for “dentistry” and limited the date of publication between 2010–2020. Over 500 articles were obtained under clinical trials, randomized clinical trials, metanalysis, and systematic reviews developed in the past 10 years in three major areas of dentistry: restorative, orofacial surgery, and periodontics. Clinical studies and systematic reviews along with hand-searched preclinical studies as potential therapies have been included. They support the proof-of-concept that novel treatments are in the pipeline towards ground-breaking clinical therapies for orofacial bone regeneration, tooth regeneration, repair of the oral mucosa, periodontal tissue engineering, and dental implants. Biomimicry enhances the clinical outcomes and calls for an interdisciplinary approach integrating medicine, bioengineering, biotechnology, and computational sciences to advance the current research to clinics. We conclude that dentistry has come a long way apropos of regenerative medicine; still, there are vast avenues to endeavour, seeking inspiration from other facets in biomedical research.
